2. How to install the macOS Monterey developer beta

First of all, you have to be an enrolled Apple developer. If not, go to Apple's developer page to enroll in the program. If you can't enroll as an Apple developer, you can also wait until the public beta program is out in a few weeks.

3. Can't install macOS Monterey on Mac

Normally, you can sign up to the Apple APP Store to download and install the macOS Monterey 12. But you could encounter problems while you are downloading or installing it.

How to fix:

If you are suffering from this problem, you probably need to check if you have enough space on the drive or volume for installation. The macOS Monterey update will take more than 4.9 GB in total.

Or you may not install to this volume because the Macintosh HD is not mounted when installing macOS Monterey, then you need to check your startup disk in Disk Utility.

Space is enough but the macOS installation couldn't be completed still? Well, you can boot your Mac into Safe Mode and reinstall macOS 12. This will isolate incompatible software when you update the sysem. Here is how to boot Mac in Safe Mode (also known as Single User mode).

  • 1. Restart your Mac and immediately hold the Shift button.
  • 2. When your Mac boot into Safe Mode, reinstall macOS 12 Monterey.
  • 3. Reboot your Mac.

Also, you may be unable to upgrade to macOS Monterey because of the error "macOS Monterey could not be verified" below, even though you have cleared out your content caching and re-download for times.

How to fix:

  • 1. Click the Apple logo at the upper left and choose System Preferences.
  • 2. Find Date & Time and open it.
  • 3. Select Date & Time panel and Click the lock to make changes at lower left.

Then restart the computer and proceed to download the update once again through settings and software update. Hopefully, it will resolve the issue of the update not being verified.

4. macOS Monterey runs into low disk space during installation

Chances are that you still can't install macOS Monterey even in Safe Mode. Sometimes, even though you have pretty much no personal file on this Mac and space appears to be enough, you still could fail to install this system due to low disk space warning. As a matter of fact, it's just one of the macOS Monterey problems many users would face.

However, if you are disturbed by the low space problem, you received the low space warning from the system.

How to Fix:

You can fix the low space issue is to delete some local Time Machine snapshots which were made by the system previously. However, if you are not a specialist, you are not advised to do this deletion in case of losing data. Instead, if you have backups in Time Machine, you can just downgrade the macOS Monterey to another stable one like Mojave and then restore your lost files.

Some users see an additional Macintosh HD - Data volume in the Disk Utility of macOS Monterey and regard it as an unknown issue. Indeed, it's not. APFS drive in macOS Monterey will be divided into two volumes. One is called Macintosh HD which contains the system information and is protected with read-only mode, while the other one is Macintosh HD - Data volume where your apps and files are stored.

To switch between your current macOS Mojave and macOS Monterey, you can access System Preferences by clicking the Apple logo at the upper left of the desktop and select Startup Disk. Then click the lock at the lower left corner to make changes, key in the password as the system asks. Finally, select your system and restart your Mac.

8. Several macOS Monterey features unavailable on Intel-based Mac

According to macOS Monteray preview by Apple, some newly updated features may be exclusive on Apple Silicon M1 Macs released in November 2020. If you find those features not available on your Mac running macOS 12, that is the reason. Those exclusive features include:

  • In FaceTime videos Portrait Mode blurred background
  • Live Text for copying and pasting, looking up, or translateing text extracted from images and photos
  • An interactive 3D globe of earth in the Maps app
  • More detailed maps in big cities such as San francisco, Los Angeles, New York, and London in the Maps app
  • Text-to-speech supports more languages including Swedish, Danish, Norwegian, and Finnish
  • Offline on-device keyboard dictation
  • Unlimited keyboard dictation that used to be limited to 60 seconds per instance

No information has been confirmed why Apple doesn't release these features to Intel-based Macs. A reasonable guess is that Apple is gradually leaving Intel-based Macs behind and keeps transitting to its custome silicon chips.

9. Windows can't be installed on M1 Mac

Boot Camp Assistant is a feature that helps users to install a Windows partition on Mac's startup disk and supports dual boot at startup. However, this software only works on Intel-based Macs.

Macs with an Apple M1 chip don't support installing Windows operating system on Mac any more (at least not now). Even though Microsoft rolled out Windows 10 ARM version, Apple has not officially supported Windows 10 on M1 Mac models. If you are an M1 Mac owner, when you launch Boot Camp Assistant an error message pops up telling you it cannot be used.

If you do need to be able to use Windows, the best way is to install virtualization software like Parallels Desktop for Mac to help you accomplish some tasks that need Windows environment.

It is possible that you install macOS Monterey on your Mac, only to find that some of your software like Microsoft Word 2011 won't run or even open in macOS 12 at all. Instead, you may receive a message like below to inform you that your app is not optimized for your Mac and needs to be updated.

32-bit Apps won't work in macOS Monterey

Why? Actually, it is because macOS Monterey doesn't support 32-bit apps anymore. Apple has been phasing out 32-bit software for the last 10 years and macOS Mojave is the last one that supports 32-bit software.

By default, macOS will tell you that the app is "not optimized for your Mac" or something like that when you attempt to open a 32-bit app in macOS Monterey. However, if it doesn't give any warning but the software just won't open, you can also check your apps for 64-bit compatibility manually.
