[macOS 27 Golden Gate](https://iboysoft.com/wiki/macos-27-golden-gate.html)introduces a redesigned experience along with new Apple Intelligence features, including the new Siri AI. But such a major macOS upgrade can also bring temporary performance problems, app compatibility issues, installation failures, and bugs that don't appear until you start using the new system with your particular Mac, apps, peripherals, and settings.

This is especially important with Golden Gate because many problems reported during the beta period involved specific hardware, third\-party software, or individual macOS components. This guide focuses on problems that are most useful to know, explains what may be causing them, and gives you practical ways to fix them.

If you're considering upgrading to macOS 27, use the guide to understand what could go wrong before you install it. If you've already upgraded and something stopped working, jump directly to the problem you're experiencing.

| Category | What you may experience | Possible causes |
| --- | --- | --- |
| **Installation problems** | Golden Gate doesn't appear, won't download, gets stuck, or fails to install | Insufficient storage; unstable internet; Software Update glitch; VPN/network filter interference; external startup disk or peripheral conflicts |
| **Boot/system instability** | Black screen, Apple logo stuck on screen, restart loops, freezes, or serious system problems | Incomplete installation; incompatible system extension or driver; startup\-disk problems; peripheral conflict; corrupted system data |
| **Performance problems** | Slow Mac, high CPU usage, heat, lag, spinning beach balls, or temporary post\-upgrade slowdown | Spotlight indexing; Photos processing; iCloud syncing; Apple Intelligence setup/model downloads; incompatible background utilities; low free storage; resource\-heavy apps |
| **App compatibility** | Apps crash, freeze, won't open, show errors, or lose functionality | Apps not yet updated for macOS 27; outdated drivers/extensions; changed permissions; Intel\-only components and Rosetta not installed; VPN/security software conflicts |

## macOS Golden Gate won't download or install

Installation problems are the first issue you may encounter because they can prevent you from getting to macOS 27 in the first place. You may find that:

- macOS 27 doesn't show up in Software Update.
- The download doesn't start.
- The download is stuck at "Checking for updates" or "Find Update."
- "Preparing macOS Golden Gate" is stuck at 30 minutes remaining.
- The Mac restarts, but the installation fails.
- Golden Gate installs, but the Mac returns to the previous system.
- The installation fails with an error message, such as " [Installation failed. An error occurred while installing the selected updates](https://iboysoft.com/howto/an-error-occurred-while-installing-the-selected-updates.html) ," " [Failed to personalize the software update. Please try again](https://iboysoft.com/howto/failed-to-personalize-the-software-update.html) ," or "This copy of the Install macOS Golden Gate.app application is damaged and can't be used to install macOS."

A macOS upgrade requires enough free storage, a stable connection to Apple's update servers, a compatible Mac, and a working startup environment. A failure at any of these stages can make the update appear stuck or cause the installation to fail.

Thus, your macOS 27 upgrade can fail because of insufficient storage, an unstable network connection, problems with the current macOS installation, incompatible models, or an issue with Apple's update service.

Problems can also occur when upgrading from a beta build, using external startup storage, or relying on third\-party software that interferes with the update process.

Although Apple fixed several installation\-related beta problems before the public release, including an issue that prevented macOS 27 from being installed to external storage connected through the DFU port, installation problems can still occur with a certain build.

### If macOS 27 doesn't appear in Software Update

Try the following first:

1️⃣ Check that your Mac supports macOS 27.

macOS Golden Gate has dropped Intel Mac support and requires Apple Silicon.

Here are the Mac models that are compatible with macOS Golden Gate:

- **macOS Golden Gate Compatibility List:**
- MacBook Neo \(2026\)
- MacBook Air \(2020 and later\)
- MacBook Pro \(2020 and later\)
- iMac \(2021 and later\)
- Mac mini \(2020 and later\)
- Mac Studio \(2022 and later\)
- Mac Pro \(2023 and later\)

2️⃣ If you have a compatible Mac, restart it and open System Settings → General → Software Update again.

![Upgrading to macOS Golden Gate in Software Update](https://iboysoft.com/images/en-howto/macos-golden-gate-issues/update-macos-golden-gate-software-update.jpg)

3️⃣ Make sure your Mac is connected to the internet, and your current macOS isn't on a beta version that's newer than the public version. For example, if you have installed macOS Golden Gate beta 27.1, then the public release of macOS Golden Gate 27.0 won't be available as an update.

### If the Golden Gate download is stuck

First, check[Apple's system status page](https://www.apple.com/support/systemstatus/)and ensure the "macOS Software Update" service is operational. If it's unavailable, the server is likely overwhelmed with a large number of download requests. Try again at a quieter time, such as before you go to bed.

If the server and your internet are working properly but macOS Golden Gate still won't download, try obtaining the full installer directly from Apple's content delivery network \(CDN\) or from Terminal.

Tips:Full Installer vs. Software Update

There are two main ways to download and install macOS Golden Gate \(27\), and they don't require the same amount of storage:

- **Software Update \(OTA\):** Downloads the files needed to upgrade your existing system and generally uses less storage than a full installer. It's the simplest option for a normal upgrade.
- **Full Installer:** Downloads the complete macOS installer, which can take up tens of gigabytes of storage. You need additional free space while the installer is downloaded, unpacked, and used for installation.
- A full installer is mainly useful when you want to install macOS manually, create a bootable USB installer, or troubleshoot problems with the normal Software Update process.

From CDN:[Download macOS Installer Safely: Apple Links and Methods](https://iboysoft.com/howto/download-macos-installer.html)

**Download macOS Golden Gate from Terminal:**

1. Open Finder and launch Terminal from the Applications/Utilities folder.
2. Type in the following command and hit Enter to download macOS 27. softwareupdate \-\-fetch\-full\-installer \-\-full\-installer\-version 27.0
3. Wait for the download to finish.

### If Golden Gate downloads but won't install

If the installation freezes or gets stuck at a certain point, make sure your Mac has enough free space to perform the upgrade.

The Golden Gate installer itself is roughly 17–18 GB, but the Mac needs additional temporary space to unpack the installer, prepare the new system, and complete the upgrade. As a practical rule, keep**at least 30–50 GB of free space**before upgrading to macOS Golden Gate, especially if you're using the full installer.

To make more free space on your Mac, clean it with[iBoysoft Cleaner](https://iboysoft.com/mac-cleaner.html). It can analyze and optimize your disk space, remove system junk files, fully uninstall apps, delete duplicate photos and files, and quickly locate large files, freeing up more space in less time.

Step 1: Free download and install iBoysoft Cleaner.

Step 2: Choose a module from the left to begin a scan.

![Make more space on Mac with iBoysoft Cleaner](https://iboysoft.com/images/en-howto/macos-golden-gate-issues/iboysoft-cleaner-interface.jpg)

Since deleting large files can quickly reclaim space, I suggest choosing**Large Files**, then select**This Mac**to scan large files on your Mac.

Step 3: After the scan is complete, choose the unwanted files and click**Remove**to permanently delete them.

![Delete large files on Mac to reclaim space for Golden Gate](https://iboysoft.com/images/en-howto/macos-golden-gate-issues/clean-mac.jpg)

Once your Mac has enough space, try the installation again.

If it continues to fail, try installing from macOS Safe Mode or a bootable USB installer.

## Mac won't boot properly after installing Golden Gate

A successful installation doesn't necessarily mean you're finished troubleshooting.

After the Mac restarts, you may encounter:

- a black screen;
- the Apple logo remaining on screen;
- a progress bar that doesn't move;
- repeated restarts;
- a frozen login screen;
- a Mac that reaches the desktop and then becomes unresponsive.

The Mac may still be completing installation or startup tasks, but a genuine installation failure, incompatible system software, or startup\-disk problem can produce similar symptoms.

If the Mac appears to be making progress, give it some time before forcing it off.

If it remains completely stuck, wait and observe whether the progress bar changes. If not, disconnect unnecessary external devices and hold down the power button to force a restart.

The last resort is to[reinstall macOS](https://iboysoft.com/howto/reinstall-macos.html)in Recovery Mode.

1. Shut down your Mac.
2. Press and hold the power button until you see "Loading startup options."
3. Select Options \> Continue \(enter your administrator password if asked\). ![Click Continue to boot into macOS Recovery mode in Apple Silicon Mac](https://iboysoft.com/images/en-howto/macos-golden-gate-issues/boot-apple-silicon-into-recovery.jpg)
4. Click Reinstall macOS \> Continue.
5. Follow the onscreen instruction.

## Mac runs slowly or feels laggy after upgrading

One of the most noticeable post\-upgrade problems on macOS 27 Golden Gate can be a Mac that suddenly feels slower.

You may notice:

- Apps taking longer to open
- Delayed window animations
- Spinning beach balls
- Slow Finder operations
- Higher CPU or memory leak
- Fans running more often
- General UI lag

This does not automatically mean that Golden Gate is too demanding for your Mac. After an operating system upgrade, macOS may need to rebuild Spotlight indexes, rescan photos, synchronize iCloud data, and perform other background tasks.

Apple also describes Golden Gate as bringing new Apple Intelligence capabilities and Siri AI, so the first period after installation may involve additional setup activity. Those processes can temporarily increase CPU, disk, memory, and power usage.

**How to tell what's causing the slowdown?**

Open Activity Monitor and check CPU, Memory, and Energy. Look for:

![Check Activity Monitor to find culprit](https://iboysoft.com/images/en-howto/macos-golden-gate-issues/activity-monitor.jpg)

- a single application consuming excessive resources;
- indexing\-related activity;
- synchronization processes;
- unusually high memory pressure.

If the Mac returns to normal after background activity settles down, the slowdown may have been temporary.

**How to fix:**

1️⃣ Keep the Mac connected to power and Wi\-Fi for several hours after the upgrade.

2️⃣ Update apps to the latest version.

3️⃣ Completely uninstall incompatible apps and clean up your Mac with iBoysoft Cleaner.

Don't assume that every performance problem is caused by Golden Gate itself. A third\-party utility that worked normally on macOS 26 may be the actual source of the slowdown.

However, if you've waited long enough, uninstalled incompatible apps, and made enough free space, but the issue remains, consider downgrading macOS or wait for another update.

## macOS Golden Gate freezes, crashes, or becomes unstable

Your Apple Silicon Mac may repeatedly freeze or restart after the Golden Gate update. Some of the symptons include:

- Finder repeatedly crashing;
- applications becoming unresponsive;
- the entire desktop freezing;
- unexpected restarts;
- severe graphical glitches;
- repeated crashes after login.

Before escalating to a macOS reinstallation or downgrading, you should rule out the culprit app or background process. Ask yourself whether the freeze or crash happens after you open certain applications. If you can tie it to an app, update or reinstall it.

If not, open Activity Monitor and look for processes that use abnormally high CPU or memory resources.

For instance, a user noticed that[corespotlightd](https://iboysoft.com/wiki/corespotlightd.html)was consistently using more than 100% of the CPU load, so he investigated Spotlight. After disabling two Spotlight settings: "Show Related Content" and "Help Apple Improve Search," the CPU load dropped, and the freeze also stopped. The issue didn't return after he turned them back on.

You can also test the Mac in Safe Mode, disconnect recently added peripherals, or check whether the problem continues with unnecessary login items disabled.

## MacBook battery drains faster after installing Golden Gate

You may notice that your MacBook loses battery faster after upgrading to macOS 27. This can happen immediately after installation without necessarily meaning that the upgrade has permanently reduced battery life.

**Why is macOS Golden Gate using more battery?**

macOS Golden Gate may consume battery faster due to Spotlight indexing and the automatic downloading of the necessary models for Apple Intelligence and Siri AI. According to Apple, Apple Intelligence and Siri AI use on\-device models for many tasks, and setup after an update can involve downloading required models.

These post\-upgrade processes can temporarily increase energy, CPU, memory, storage, network, and other activity. But that doesn't mean that they will necessarily cause long\-term battery drain.

To check what programs are consuming battery, go to Activity Monitor \> Energy, then check which applications are using the most energy. Also check whether the battery behavior improves after leaving the Mac connected to power and Wi\-Fi for several hours.

If battery life remains substantially worse after the system has settled, investigate the individual applications or processes responsible. You can fix the battery drain by:

- Updating all apps for macOS Golden Gate support.
- [Resetting the SMC](https://iboysoft.com/wiki/system-management-controller.html) to reset battery management.
- Open System Settings \> Battery, and choose **Always** for **Low Power Mode** .
- Go to System Settings \> Accessibility \> Display \> enable Reduce Transparency, and then Accessibility \> Motion \> Reduce Motion.
- Open System Settings \> Apple Intelligence & Siri, then turn off features you don't use.

## Apps Crash, Freeze, or Won't Open on Golden Gate

Application compatibility is also one of the known macOS Golden Gate problems, as an operating\-system upgrade can change APIs, security behavior, and system frameworks that applications depend on.

You may find compatibility problems in third\-party applications, especially Intel\-based apps or utilities that interact deeply with macOS, such as mouse software, display utilities, security software, VPNs, backup tools, and system\-management applications.

Besides, authentication plugins and other pre\-login utilities that require Rosetta may not work in Golden Gate, because Rosetta isn't available for those components at the relevant stage of startup.

You might find that an app:

- Crashes immediately after opening
- Freezes during normal use
- Stops responding
- Loses access to a peripheral
- Behaves differently than it did on macOS 26
- Requires an update before it works correctly
- Report an error

Here are the causes behind the apps that don't work on macOS Golden Gate:

**Cause 1: The app has not been updated for macOS 27**.

**Cause 2: The app still depends on Intel code**.

Golden Gate requires an Apple Silicon Mac and is the final macOS generation with Rosetta 2 support.

If an Intel\-based application requires Rosetta, macOS may prompt you to install it when you first launch the application after upgrading. You can also check System Settings \> General \> About \> Intel\-Based Apps \> Details to identify applications that still rely on Intel code.

![Check all the Intel apps on macOS Golden Gate](https://iboysoft.com/images/en-howto/macos-golden-gate-issues/intel-app-on-golden-gate.jpg)

Generally, you can try the following solutions to**fix apps not working on macOS Golden Gate:**

- Update the affected app.
- Check the developer's compatibility information.
- Restart the Mac.
- Check whether the problem occurs in another user account or with a clean environment.
- Temporarily disable related background utilities.
- Reinstall the application if necessary.
- Uninstall the app completely.

If the application has become obsolete and you no longer need it, a complete uninstall may be better than repeatedly troubleshooting it.

When removing a third\-party application, don't just drag its icon to the Trash if you want to remove its associated files as well. Leftover preferences, caches, support files, and background components can remain. Use a tool like iBoysoft Cleaner to remove the app and all files related to it completely.

### Intel Apps Show "Bad CPU Type in Executable" in Terminal

Some older applications \(e.g., git or vcprompt\) may fail to launch on an Apple Silicon Mac after upgrading to Golden Gate. One possible error is "Bad CPU type in executable." This is because the application or one of its components may still depend on Intel architecture.

macOS 27 is still within the period in which Rosetta 2 supports Intel applications, but Apple's Golden Gate release notes indicate that Rosetta behavior has changed. In particular, Rosetta is not automatically restored after an upgrade if it was previously installed.

To continue using the Intel app, you can either reinstall Rosetta or switch to its Apple Silicon version if available.

**Method 1: Install Rosetta from Terminal by running the command below:**

softwareupdate \-\-install\-rosetta \-\-agree\-to\-license

Then try opening the application again.

**Method 2: Install the Apple Silicon version**

If the application still doesn't work, check whether its developer provides a newer Apple silicon\-compatible version.

## macOS Golden Gate memory leak

After installing macOS Golden Gate, you may notice unusually high memory usage that gradually makes the Mac slower, less responsive, or even forces a restart. In some cases, memory pressure increases over several hours rather than immediately after startup. Users have reported symptoms such as beach balls, delayed UI responses, extremely slow performance, and "Your system has run out of application memory" warnings.

Background processes like dasd or[WindowServer](https://iboysoft.com/wiki/windowserver-mac.html)may consume tens of gigabytes of RAM and swap, sometimes reaching 40–70 GB and eventually causing the Mac to freeze.

**How to identify the culprit of high memory usage?**

1. Open Activity Monitor.
2. Select the **Memory** tab.
3. Sort processes by the Memory column.
4. Watch the top processes for several minutes.
5. Check whether one process continues growing without releasing memory.

**How to fix memory leak on macOS Golden Gate?**

1️⃣ Update macOS.

If the excessive memory usage is caused by a macOS bug, installing the latest Golden Gate update is the most meaningful solution.

2️⃣ Update or stop the app responsible.

If a third\-party app is consuming excessive memory, check whether a newer version is available for macOS 27 Golden Gate. If the problem continues, quit the app or temporarily avoid using it until the developer releases a compatible update.

3️⃣ Understand and address the process causing the high memory usage.

Once you identify a process consuming excessive memory, find out what the process does before deciding what to do with it. This helps you distinguish a normal background task from a potential memory leak.

For example,dasd is a macOS system process associated with Duet Activity Scheduler, which manages and schedules background activities. Unusually high dasd usage suggests that something may be repeatedly scheduling or triggering background work.

To discover what app or feature is triggering it, you should continue investigating what other system processes are doing at the same time or what apps are showing unexpected behaviors. You may soon notice that BiomeAgent was repeatedly registering the Apple Intelligence task com.apple.intelligenceplatform.IntelligencePlatformCore.ViewLive. Then conclude that repeated registration of that task appeared to be causing dasd to accumulate memory.

You can allow the process to finish, quit it to restart the process or disable it.

## Wi\-Fi or network connections keep dropping

Networking problems on Golden Gate can be particularly confusing because several completely different problems can produce the same symptom: "the internet doesn't work."

Before changing system configuration files, determine which type of failure you have.

**Cause 1: Only certain applications cannot connect**

If Safari works but Chrome, Discord, VS Code, Dropbox, or another application cannot connect, the problem may involve a network filter rather than Wi\-Fi itself.

VPNs, firewalls, antivirus products, content filters, and corporate security software can interact with macOS networking at a low level.

One community report documented a group of Chromium/Electron applications failing to connect while Safari continued working, with network\-filter software identified as a contributing factor.

Temporarily disable the relevant third\-party network software and test again.

If that fixes the problem, update the security or VPN software rather than repeatedly resetting macOS networking.

**Cause 2: The Mac cannot connect to the network at all**

Start with the low\-risk checks:

- Turn Wi\-Fi off and back on.
- Restart the Mac.
- Restart the router.
- Forget the Wi\-Fi network and reconnect.
- Test another network.

In\-Depth reading:[Mac Connected to Internet but No WiFi](https://iboysoft.com/howto/mac-connected-to-wifi-but-no-internet.html)

If the problem affects only one Mac, continue troubleshooting on the Mac rather than assuming the router is defective.

## Apple Intelligence or Siri AI isn't working

Golden Gate introduces new Apple Intelligence capabilities and Siri AI. Some features may require additional setup after upgrading, and availability can depend on the Mac, language, and region.

If an Apple Intelligence feature isn't immediately available, ensure you:

- Set your Mac and Siri with the same language.
- Have enough free space for on\-device models \(typically around 7 GB\).
- Have an Apple Silicon Mac with an **M1 or later chip** for standard features.
- Have **M3 or later** chip with at least **12 GB of unified memory** for advanced on\-device feature.
- Check whether the feature supports your language, and region.
- Make sure the Mac is connected to power and internet and has given enough time to complete setup.

## External displays don't work correctly

Some Golden Gate users have reported external\-display problems after upgrading to macOS Golden Gate, including a monitor that isn't detected, a black screen even though the display is connected, or a second external monitor that stops working when multiple displays are connected.

First determine whether macOS detects the monitor. Go to**System Settings \> Displays**while the monitor is connected.

| **If the monitor doesn't appear** | Test the cable, port, dock, and monitor separately. If possible, connect the monitor directly to the Mac instead of through a dock. |
| --- | --- |
| **If the monitor appears but shows a black screen** | The connection is being detected, so investigate the display configuration and macOS's multi\-display behavior. |
| **If the monitor works when mirrored but not when extended** | This points more strongly toward an Extended Display, Spaces, or window\-management problem than a completely failed connection. |
| **If one monitor works but the second doesn't** | Disconnect both and test them individually. If each monitor works alone but they fail when connected together, investigate the multi\-display configuration, dock, connection method, or macOS 27 before replacing either monitor. |

Then fix it with the solutions below:

1️⃣ Update macOS.

If the problem appeared after upgrading to Golden Gate, install the latest macOS 27 update available.

2️⃣ Toggle "Displays have separate Spaces."

If the monitor works as a main display or in Mirror mode but shows a black screen when used as an extended display, try changing:**System Settings**\>**Desktop & Dock**\>**Mission Control**\>**Displays have separate Spaces.**

This is particularly worth trying when the display is detected but the extended desktop is not rendered correctly.

3️⃣ If you use DisplayLink, update DisplayLink Manager.

Check that you are using a version of DisplayLink Manager that supports your macOS 27 build. If there's a new DisplayLink Manager version, install it. As we know, DisplayLink Manager 16.2 has already introduced beta support for macOS 27 and included fixes for some blank\-display problems.

4️⃣ Connect the affected monitor directly to the Mac if possible.

5️⃣ Reset display preferences.

If the monitor worked before the Golden Gate upgrade, continues to work with another device, and the usual connection tests do not help, corrupted or stale WindowServer display preferences may be contributing to the problem.You can reset the display preferences to resolve the issue if you don't mind resetting display\-related configurations.

To reset the preference, you can delete the WindowServer display preference files with the commands below in Terminal and restarting macOS.

sudo rm /Library/Preferences/com.apple.windowserver\*.plistrm ~/Library/Preferences/ByHost/com.apple.windowserver\*.plist

## Spotlight doesn't find apps or results correctly

After upgrading to macOS 27 Golden Gate, Spotlight may behave differently from before. It may fail to show applications, display inconsistent search results, or missing some results.

Ordinary Spotlight searches depend heavily on indexing. So, initiate a Spotlight reindexing is a common solution.

For ordinary file and application searches:

1. Restart the Mac.
2. Give Spotlight time to finish indexing after the upgrade.
3. Check Spotlight settings.
4. Rebuild the Spotlight index if ordinary search results remain incomplete.

Some newer intelligence\-related results involve additional Apple Intelligence components, so rebuilding the normal index isn't necessarily a solution to every Spotlight\-related problem.

If files and applications can be found normally but intelligence\-related results are missing, check that the relevant Apple Intelligence features are enabled, your language and region are supported, and the required models have finished downloading.

## iPhone Mirroring or Mission Control isn't working

Early testers reported iPhone Mirroring becoming stuck while loading and Mission Control/App Exposé failing to display all windows consistently.

Because these features depend on multiple system components, avoid immediately changing unrelated settings.

Try:

- Update macOS Golden Gate.
- Restart the Mac.
- Restart the iPhone if the problem involves iPhone Mirroring.
- Confirm that the relevant devices are signed into the expected Apple Account.

## Should you upgrade to macOS Golden Gate?

The answer depends less on whether macOS 27 has bugs and more on how much those bugs could affect your particular workflow.

**Upgrade to Golden Gate sooner if:**

- Your important applications already support macOS 27.
- You have a current backup.
- You use mainstream hardware and peripherals.
- You can tolerate some troubleshooting.
- You want the new macOS 27 features.

**Consider waiting for 27.2 or 27.3 if:**

- Your Mac is essential for work.
- You depend on specialized professional software.
- You use unusual peripherals or drivers.
- You rely on complex multi\-monitor setups.
- You cannot afford even a short period of incompatibility.

Waiting a few weeks can allow Apple and third\-party developers to address problems.

## 5 things to do before installing macOS Golden Gate

1. Back up your Mac

Have a current backup before starting the upgrade. Don't treat a major macOS update as a routine app update.

2. Check your important applications

Don't just ask whether an application launches. Check whether the features you actually use for work continue to work.

3. Update third\-party utilities

Pay particular attention to:

- VPN software
- security software
- mouse and keyboard utilities
- display utilities
- backup applications
- audio software
- hardware drivers
- system\-management tools

4. Make enough storage available

A major macOS upgrade needs working space during installation in addition to the space occupied by the finished operating system. To[free up space on Macintosh HD](https://iboysoft.com/howto/how-to-free-up-space-on-macintosh-hd.html)and improve performance, get iBoysoft Cleaner to remove unwanted files and files buried deep in the hard drive.

5. Make sure you have a recovery plan

Know where your backup is and how you would recover your files if the upgrade caused a serious problem.

## FAQs

AThe public release should be more mature than the earlier beta builds, but no major operating system release is free of compatibility problems. The actual experience can depend on your Mac model, applications, peripherals, and configuration.

AOnly if the upgrade causes a serious problem that you cannot work around, particularly if a critical application or peripheral is incompatible. Temporary performance problems immediately after upgrading aren't necessarily a reason to downgrade.

AYour Mac may still be indexing files, processing Photos data, synchronizing information, or completing Apple Intelligence setup.
