But what do you do if you encounter any issues when installing Monterey? Let’s dive into a few quick fixes that address that problem here.

Why Won’t macOS Monterey Install?

Normally, your Mac should be able to install macOS Monterey like this.

Anytime a new update is released, there can be various bugs and issues that come along with it. These are usually ironed out pretty quickly by developers, in this case, Apple, but before that happens, you might encounter an issue.

If you are having trouble with the Monterey install, you can try any of the fixes below. But if that doesn’t work, you also might need to wait until Apple deals with the problems directly.

Fix #1: Check for Compatibility

If you are experiencing any issues with installing macOS Monterey, a recommended first step is to check and make sure that the computer you are trying to install the update on is compatible with the update.

If it’s not, you won’t be able to download and install the program. You will usually see a message indicating incompatibility when you first start to attempt to download the update but might experience the issue further down the installation line as well.

Fix #2: Make Sure There is Enough Available Disk Space

You also might be experiencing issues with installing macOS Monterey if there isn’t enough free disk space on your computer. This is another common problem that is quick and easy to fix.

You can delete any files that you don’t need, such as photos and videos. Removing unused apps is another way to free up enough disk space to complete the installation quickly.

And you can always reinstall these apps later on if you need or want them on your system.

To install macOS Monterey on your computer, you will need at least 35 GB of free storage, the more the better. If you can’t free up that much storage, try using a Mac cleaner app.

Fix #3: Perform First Aid in Recovery Mode

Since the update for macOS Monterey was just released, there isn’t an abundance of information on how to fix every issue you might encounter when attempting an install.

But that doesn’t mean you can’t try a fix that worked in the past on different versions of macOS that were experiencing similar issues. You can follow the steps below for a potential fix that can help resolve the issue of Monterey not installing.

  1. Restart the computer while holding down the Command and R keys at the same time. This will allow you to access the Utility Menu upon startup.
  2. When you see the Utility Menu on your screen click on Disk Utility.
  3. Select Continue.
  4. You will see a list on the side of the window and you should click on the indented volume entry from here.
  5. Click on the First Aid tab.
  6. Once you see the Done button appear, click on it.
  7. Quit the disk utility menu.
  8. Restart the computer again.
  9. Attempt another install of macOS Monterey.

Fix #4: Force a Reboot After Freeze

One issue being reported when attempting to install macOS Monterey is the computer freezing after the installation process has begun. This is a specific problem that you might encounter when you see the Setting Up Your Mac screen, as seen below.

If you reach this point of the installation, but then nothing happens, and your Mac seems frozen, don’t panic because the fix is pretty straightforward.

If you have gotten this far with the installation process, the update should actually be installed on your computer, and all you need to do is force a restart and fix the problem.

To force a restart of your computer, just hold down the power button until it turns off. Wait for about 10 seconds, and then start the computer up again. After the computer starts up again, you should have Monterey installed successfully.

Fix #5: Try to Install macOS Monterey in Safe Mode

Another option you can use if Monterey won’t install on your computer is to attempt another install with your computer in Safe Mode.

Safe Mode is a way to start up your Mac computer without any other programs running that may be causing an issue with the software update.

The software necessary to allow the computer to run will still work but Safe Mode prevents unneeded software from running and can help you diagnose certain issues.

To boot your Mac in Safe Mode follow these steps:

  1. Shut down your computer if it is currently on.
  2. Wait until the computer is completely powered off.
  3. Press the power button to turn the computer back on.
  4. When you hear the startup sound, immediately press the Shift key.
  5. Release Shift key when you see the Login window.
  6. Once you are in Safe Mode, you can attempt to install macOS Monterey again.

Final Thoughts

Hopefully, one of the fixes mentioned here has allowed you to install macOS Monterey on your computer properly. If it doesn’t, you may need to keep searching for solutions to help with the installation.

You can always reach out to Apple’s customer support or search for a good Mac forum, such as CNET or Apple Discussions.

And just know that if you are experiencing an issue with installation soon after the update has been released, any bugs causing this should be worked out fairly quickly.

    Simple comment: Apple should not sell a MacBook with less than a 250GB disk. Operating system upgrades for my 128GB Mac are virtually impossible and VERY frustrating! With each attempt, the amount of disk space required changes, etc etc
