How to fix macOS Monterey installation issues

The first problem you may encounter is the inability to update your macOS. macOS Monterey's official release date is October 25, 2021 - so from that time on every Mac user is entitled to update. Here are the possible problems:

• macOS Monterey not shown as available
• macOS Monterey download failed
• macOS Monterey cannot be installed
• macOS Monterey update stuck or freezes
• Mac cannot start after update

macOS Monterey not shown as available

To get a new macOS on your Mac, you should go to the Apple menu and download it from About Native > Software Updates. If you turn on "Software Update" but don't see macOS Monterey, you can try these three ways:

1. Check device compatibility. We list compatible Mac models below.
2. Press Command R to refresh the Software Update dialog box. If there is some kind of network error, this should fix the problem.
3. Download macOS Monterey from the App Store.

macOS Monterey download failed

What if the update itself is available but you can't download it?

When trying to download Monterey from "Software Update", you may see an error message saying "Installation cannot continue" or something like that. Some possible solutions:

Check device compatibility

macOS Monterey does not support some older Mac models, so it may not run on your Mac at all. Here is a complete list of macOS 12-compatible Mac models:

• MacBook Air (early and beyond 2015)
• MacBook Pro (early and later 2015)
• MacBook (early and beyond 2016)
• Mac mini (late 2014 and beyond)
• Mac Pro (late 2013 and beyond)
• iMac (late 2015 and beyond)
• iMac Pro (2017 and beyond).

Repair Wi-Fi

Network connection is crucial when installing software updates. If your Wi-Fi signal is weak, an installation error may occur. To determine if this is the case, you need to use WiFi Explorer. Simply open the app and click on your network connection to check signal strength and noise levels. If you have multiple available network hotspots, WiFi Explorer will tell you which network connection is the best.

Fix "Gateway Timeout" error

If you have started the download process and then it suddenly breaks and displays an "gateway timeout" or an alert similar to "error gateway", you should try restarting your Mac in safe mode. Just hold down the Shift key while the Mac is booting. This should solve the problem.

macOS Monterey cannot be installed

Maybe you have completed the download process, but can't continue because macOS 12 cannot be installed. Too bad. Often, some kind of compatibility or verification problem is the cause of this problem.

You may need more storage

macOS Monterey download and successfully install it takes about 12GB of space. Ideally, you should free up at least 20GB of space. If you don't have that much storage on your drive, delete some cluttered files from your Mac.

CleanMyMac X is the fastest and most reliable tool to free up Mac storage space. Run a smart scan to identify any system cluttered files, duplicate files, old caches – all content that should be deleted. Then delete it with one click. As a result, CleanMyMac X frees me about 10GB of space per month. If you haven't cleaned up for a while, you'll get more space.

macOS Monterey cannot be installed when using non-Apple SSD

Some users report that even if their machines are compatible, they cannot install macOS 12 on Macs that have non-Apple SSDs installed. This does happen and you should run a firmware update to fix this. Don't worry, you won't lose SSD data. Here are what you should do:

1. Connect to Apple SSD
2. Run firmware updates
3. Reinstall your non-Apple SSD while running Monterey.

"Unable to install required firmware update" issue

Some users have problems trying to update the firmware. The first thing to check is the internet connection. Use WiFi Explorer to ensure you have a stable connection as this is essential for firmware updates.

Also, be aware that you cannot update the firmware on non-Apple SSDs. To get it working you must first get an Apple SSD.

macOS Monterey update stuck or freezes

If you have started the update process but it takes too long to complete the update, your Mac may be stuck. You can do the following:

1. Make sure it really gets stuck . Press Command L to view detailed information about the update process. Your Mac may not be frozen, it just takes a long time to install the update. In this case, you should wait a moment.
2. Restart your Mac in Safe Mode : Apple Menu > Close > Hold down the Shift key when restarting your Mac > Release the Shift key after you see the login window. Then, try installing Monterey again.
3. Reset NVRAM : Turn off Mac > Press and hold Option Command PR for 20 seconds > Release the key and wait for the Mac to boot normally. Install Monterey.

macOS Monterey makes certain Macs unusable, unable to boot, or brick

There are some reports that the Mac cannot boot after the update. It's no exaggeration to say that this is one of the toughest issues as it can make your Mac unavailable.

This happens primarily on older Macs, and never on Macs with Apple M1 chips installed. The possible solution is to try to restore the firmware of your computer, and you definitely need the help of Apple experts.
