The possible causes of checking for updates stuck

Given that Apple no longer offers delta and combo macOS updates as standalone downloads since macOS Big Sur, you need to download and install the entire update package which makes the macOS updates so large. Therefore, it may take more time for the system to check for updates. But if you wait for hours and it remains on the screen without any change, then it is most likely that there are errors on Mac causing the checking for updates stuck.

Proven fixes for Mac stuck on checking for updates

After knowing the possible causes of the checking for updates stuck on Mac, here we can proceed to the detailed fixes to get the update stuck problem resolved. You can apply these fixes one by one to get rid of the error so that you can perform a normal update on the Mac and won't receive the error - macOS Monterey cannot be installed on Macintosh HD. Let's dive into it now.

  Check the internet connection

An unstable and poor internet connection can contribute to the Mac failing to find and download the available updates and stuck on the "Checking for updates…" screen. Therefore, the first move is to check the internet connection of your Mac computer. 

To eliminate the internet connection error, you can reconnect to the Wi-Fi or change to another Wi-Fi, restart your router, and unplug and replug the power cord. Then you can head to the Apple menu > System Preferences > Software Update to check for updates on MacBook again.

  Check available storage space on Mac

As we mentioned before, the macOS updates become larger than before. According to Apple, macOS Monterey requires 26GB of available storage to upgrade from macOS Sierra or later, and requires up to 44GB of available storage to upgrade from an earlier release. Thus, you need to make sure there is sufficient storage space on the startup disk to install macOS updates. Otherwise, it may lead to the Mac stuck on checking for updates.

How to check storage space on Mac:

  1. Click the Apple logo at the top left corner of your Mac computer.
  2. Choose About this Mac from the dropdown menu.
  3. Select the Storage tab from the pop-up window.
  4. Wait for a second and then the system will return the results of whole storage space, used space, and free space.

If the free space is not enough for the macOS updates, you need to free up space on Mac to reclaim more available space on the drive to install the macOS updates such as uninstalling unused apps, deleting unwanted downloads, moving or deleting large files, and so forth. 

  Restart your Mac

Inevitably, your Mac suffers some abnormal situations from time to time, like Mac runs slowly, the Mac fan is so loud, apps crush suddenly, etc. In these cases, restarting Mac is a tried-and-true cure to get the malfunctioned Mac back on track. And it may work to solve the checking for updates stuck on Mac issue by giving the Mac a fresh start.

  Update macOS in Safe Mode

Restarting your Mac doesn't work and the Mac is still stuck on the checking for updates screen? Then, you can try to boot Mac into Safe mode to install macOS. It is a diagnostic mode of the operating system, performing certain checks and preventing unnecessary programs and drivers but basic startup items from loading or opening during the startup. Perhaps, you can successfully download and install macOS updates in Safe Mode.

Boot an Intel-based Mac in Safe Mode:

  1. Turn off your Mac computer and wait for 10 seconds.
  2. Press the power button to restart your Mac and simultaneously hold down the Shift key.
  3. Release the Shift key until seeing the login window.

Boot an Apple M1 Mac in Safe Mode:

  1. Shut down your Mac computer and wait for 10 seconds.
  2. Press down the power button until the startup options and the Options gear icon appear on the screen.
  3. Choose your startup disk.
  4. Hold down the Shift key and click Continue in Safe Mode. Then, release the Shift key.

After entering safe mode on Mac, you can try to check for updates in System Preferences again. After you finish installing the macOS, you can restart the Mac to quit the Safe Mode.

  Reset NVRAM and SMC

NVRAM stores OS-related settings to enable the Mac to start up quickly and perform properly. If there are any bugs in NVRAM, it will cause unexpected issues on your Mac, including Mac stuck on checking for updates. Therefore, you can give it a shot to reset NVARM on Mac. Unluckily, you fail to update macOS after resetting NVRAM, you can apply to reset SMC, a component responsible for lots of parts in the Mac. That's worth a try.

  Install macOS from Apple Store or Apple's site

If you are unable to update macOS in Mac's System Preferences, you can find other ways out. There are two alternative ways, installing the latest macOS from the Apple store and from Apple's site - support.apple.com. Just search for the version of macOS you prefer and follow the guide to download and install it on your Mac. By the way, you can't find macOS Mojave/Catalina/Big Sur in App Store given that Apple hides the entries of these earlier versions.

  Update macOS using Terminal

In addition to updating macOS in System Preferences, from the Apple store and Apple's site, you can also do it by using Terminal, the macOS utility. It can bypass any bugs on Mac to perform a macOS installation with the Terminal command. 

1. Go to Applications > Utilities and from there start the Terminal app.

2. In Terminal, type the following command and press Enter/Return to execute it:

sudo softwareupdate -l

3. Type in your password and press Enter/Return again.

4. To download and install a particular update, use the command:

sudo softwareupdate -i 'NAME'

You should replace NAME with the particular update you want to download and install such as 'macOS Big Sur 11.4-20F71'

5. The update you've selected will start to download and will automatically start installing once downloaded.

  Reinstall macOS

The software update stuck on checking for updates may result from errors in the current operating system on your Mac computer. A corrupted OS usually leads to the Mac behaving in an abnormal way. To troubleshoot a problematic operating system, you can reinstall macOS on Mac. It needs to boot Mac into Recovery mode. Before that, you should back up your Mac because reinstalling macOS will delete all the contents on Mac.
