Check internet connection

Even if you're installing macOS Ventura from a downloaded installer, the internet is still needed for the installer to get firmware and other information specific to your Mac. So, you should make sure that your Mac has a working and stable internet connection. Consider using an ethernet cable if your WiFi is slow.

Or, you can directly download macOS 13 from the macOS Ventura download database.

Reboot your Mac and retry the installation

Sometimes, a reboot is all you need to get past the installation error, as it can fix all sorts of minor glitches, clear the memory and give your Mac a fresh start. You can click the Apple menu and choose Restart to reboot your Mac. After it starts up, retry installing macOS Ventura. You might need to try several times for the installer to work correctly.

If you still can't install macOS Ventura after several attempts to rerun the installer, move on to the next fix.

Ensure Macintosh HD is APFS-formatted

If you are upgrading from an old version of macOS, your Mac may still be formatted with Mac OS Extended (Journaled), also known as HFS+, rather than the required APFS for macOS Ventura. Incompatibility could also lead to SDErrorDomain error 104 and you may not install to this volume missing firmware partition. To verify what file system your Mac has, open Disk Utility, select Macintosh HD, and you can find the info on the pop-up window.

Check the file system of your startup disk

If Macintosh HD is indeed formatted with Mac OS Extended (Journaled), you need to reformat your startup disk into APFS following the last method in this post.

If your Mac is already with APFS, keep reading other solutions below.

Set your Mac to the correct date and time

It's possible that your Mac has incorrect Date & Time settings. When that happens, it may result in issues connecting to the Apple Server, which could be the reason why the installation failed with "macOS Ventura cannot be installed on Macintosh HD."

Follow these steps to make sure your Mac has the correct date and time:

  1.  Open System Preferences > Date & Time.
  2. Click the padlock and enter your administrator password.
  3. Check the box before "Set date and time automatically."
    Configure your Mac to set date and time automatically

If the "macOS Ventura not installing" issue persists, continue with the next solution.

Delete the installer and redownload it

Chances are that the macOS Ventura installer may have become corrupted somehow. Since you can't upgrade to Ventura if its installer file is corrupt, it's a good idea to delete the installer from your Applications folder, empty Trash, and download a new one from the App Store.

After the new installer is ready, install macOS Ventura again to see if makes any difference.

Install macOS Ventura from Software Update

If "macOS Ventura cannot be installed on Macintosh HD" pops up, you likely have tried to install macOS Ventura from the full installer downloaded from App Store or a bootable USB drive. Either way, you should try upgrading to Ventura via the Software Update pane.

Different from previous major updates, upgrading to macOS Ventura from the Software Update pane will install macOS Ventura to your Mac automatically without asking you to select the startup disk or save an installer to the Applications folder.

To upgrade from macOS Monterey or earlier to macOS Ventura, open System preferences > Software Update, and click "Upgrade Now."

Install macOS Ventura from Software Update

Update to the latest version of your current macOS first

Suppose your Mac won't update to Ventura directly. You can try updating your current macOS release to the latest version first. Besides releasing a major macOS update annually, Apple also keeps the major update maintained with security patches in small point releases.

You're recommended to install these minor releases before upgrading to macOS Ventura, as it can often fix different problems on your current macOS and increase the possibility of a successful upgrade. Here's how to do it:

  1. Open System Preferences  > Software Update.
  2. Click "More info" if any.
    Update the currently installed macOS to the latest before upgrading Ventura
  3. Select the available update and click "Install Now."

After the installation is complete, you can install macOS Ventura again.

Install macOS Ventura in Safe Mode

Alternatively, you can upgrade to macOS Ventura in Safe Mode. Booting into Safe Mode only allows the essential components to be loaded and can thus prevent third-party programs from interfering with the installation. Note that the processes of restarting in Safe Mode on Apple Silicon (M1 & M1) Macs differ from Intel-based Macs.

On Intel-based Macs:

  1. Turn off your Mac.
  2. Press the power button, then immediately press and hold the Shift key.
  3. Release the key when you see the login screen.
  4. Log into your account.

On Apple Silicon Macs:

  1. Shut down your Mac.
  2. Press and hold the power button until seeing "loading startup options."
  3. Select your startup volume.
  4. Hold the Shift key and click "Continue in Safe Mode."

Once you're in Safe Mode, you should see the words "Safe Boot" in the top-right of the menu bar. Perform the installation again to see whether you can upgrade to Ventura.

Mac Safe Mode

Install macOS Ventura from App Store

If you weren't running the Vetnura installer downloaded from App Store, you should definitely try it out. Simply open App Store and search for macOS Ventura, then follow the on-screen instructions to install it.

Install macOS Ventura from Internet Recovery

When you reinstall macOS from Local Recovery Mode, you usually get the current version of the most recently installed macOS. However, if your Mac is Intel-based, you can reinstall the latest macOS that's compatible with your Mac via Internet Recovery.

With that said, you can upgrade to macOS Ventura by reinstalling macOS. This replaces your current macOS version but keeps all the data on your Mac intact. Follow the steps below:

  1. Shut down your Mac.
  2. Press the power button, then immediately press and hold the Option + Command + R keys.
  3. Release the keys when you see the spinning globe.
  4. Select a WiFi network if you're using one.
  5. When the macOS Utilities window pops up, select "Reinstall macOS Ventura" and click Continue.
    Install macOS Ventura from Internet Recovery
  6. Follow the onscreen instructions to reinstall macOS and upgrade to the latest macOS Vetnura.

Install macOS Ventura with a bootable USB drive

Another popular way to install macOS Ventura is by booting from a USB drive. If you haven't tried it already, you can create a bootable USB installer, boot from it, and point the installer to Macintosh HD. To prevent the installation from getting the error reading "macOS Ventura cannot be installed on Macintosh HD," you need to ensure the followings are checked:

  • The macOS Ventura USB installer needs to be formatted with Mac OS Extended (Journaled).
  • Ensure your Firewall settings allow all incoming connections. (Open System Preferences > Security & Privacy > Firewall, tap the padlock and enter your administrator password, uncheck "Block all incoming connections" and check "Automatically allow built-in software to receive incoming connections."
  • Open Startup Security Utility to allow booting from external or removable media if it's a T2 Mac.

Install macOS Ventura on the original SSD

If the error reading "macOS Ventura cannot be installed on Macintosh HD" appears when upgrading macOS on a new internal hard drive, you need to switch back to the original SSD. That's because the EFI Boot ROM included in Ventura needs to verify for the original SSD. If it's not found, macOS Ventura won't install on your Macintosh HD.

Therefore, you need to put the original hard drive back into your Mac and install macOS Ventura on it. After that, replace it with the new drive and rerun the installation.

Repair your startup disk

macOS Ventura won't install on Mac if your startup disk has disk errors. It's advisable to check and repair your Mac with Disk Utility First Aid and then attempt the installation of macOS Venture one more time to see if it works. Here's how to repair your startup disk on Mac:

  1. Shut down your Mac.
  2. Boot into Mac Recovery Mode.
    On an Intel-based Mac: Hit the power button, then immediately press and hold the Command + R keys until you see the Apple logo.
    On an M1 & M2 Mac: Press and hold the power button until "Loading startup options" appears. Then click Options > Continue.
  3. If you're asked to select a user you know the password for, select one, click Next, then enter the administrator password.
  4. Select Disk Utility > Continue.
  5. Click View > Show All Devices.
  6. Select the last volume list under your internal storage, click "First Aid," then tap the Run button.
    Repair startup disk in macOS Recovery
  7. After repairing the last volume, continue checking the volume above it until the disk (usually labeled similarly to Apple SSD) has gone through the repair process.
  8. Click on the Apple menu and select Restart to reboot your Mac.
  9. Try again to install macOS Ventura.

Free up space on Macintosh HD

Your Mac won't update to Ventura if it lacks the storage space to accommodate the installation. Though the full Ventura installer is about 12 GB, you'll need extra space to run it. If you're upgrading from macOS Sierra or later, prepare at least 35GB of free space for macOS Ventura. But if you're upgrading from an earlier version, macOS Ventura requires up to 44GB of free space.

You can open the Apple menu > About This Mac > Storage to view the available space on your Mac. If it doesn't have enough storage for Ventura, you can free up space on Macintosh HD by deleting unwanted files and emptying the Trash.

If you prefer an easier way to clean the junk files on your Mac, you can free download iBoysoft DiskGeeker.

The clean Junk feature of iBoysoft DiskGeeker

It features "Clean Junk" and "Clean Drive" to help you get rid of unwanted files easily. With "Clean Junk," you can find and delete unnecessary temporary files, user caches, log files, etc. And "Clean Drive" allows you to browse all files on your Mac and sort them by size so that you can quickly locate and trash the files that are taking up space on Macintosh HD.

Clean install macOS Ventura

If macOS Ventura won't install despite you've tried all the above solutions, the last resort is to erase your Mac before retrying installing macOS Ventura. This will remove all data on your hard drive, so back up your Mac before attempting the steps below.

  1. Turn off your Mac.
  2. Boot into macOS Recovery Mode.
    On an Intel-based Mac: Hit the power button, then immediately press and hold the Command + R keys until you see the Apple logo.
    On an M1 & M2 Mac: Press and hold the power button until "Loading startup options" appears. Then click Options > Continue.
  3. Select Disk Utility > Continue.
  4. Click View > Show All Devices. (Jump to step 7 if your startup disk isn't APFS-formatted.)
  5. Select Macintosh HD - Data and click the ( - ) button to delete it.
  6. Continue deleting other internal volumes except for Macintosh HD.
