can I update macOS high Sierra to Monterey
iMac 21.5″, macOS 10.13
Thanks so much. This worked. I am sure glad I had a time capsule for backups. I got to get one for this computer before I update this one. It has macOSHigh Sierra also. Do you recommend that I update to one of the later softwares before doing Monterey again. Thanks again.
How to update from Mac OS High Sierra to Monterey?
Shutdown by any means required including the Power Button.
Disconnect any and all external drives.
Restart and Immediately hold the SHIFT key until the Apple Logo is presented and then release the key. If using a Bluetooth Keyboard, suggest using a Wired Keyboard as the Bluetooth may or may not work as well.
The Safe Mode will do a repair disk, clear cache files and only load Apple Software, extensions and fonts. The loading will be slow and cold take up to 10 minutes to load depending on the amount of data on the drive. This is all normal.
The Safe Boot may or may not allow the upgrade process to complete

It might be better to upGrade to Catalina or Big Sur first. Then, attempt the Monterey upGrade.

Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina, Big Sur & Monterey supports only 64 bit and there is no workaround.
Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may required update or upGrades to 64 Bit Versions.

Caution - jumping over all the newer versions and directly to Monterey on Qualifying computers is Technically possible - there are those who have attempted and were successful. Then there are those who attempted and had less than good results.
If this is a Production or Mission Critical Set-up - a more prudent and measure approach is suggested.

I was able to install Monterey but on the final install where the computer did a restart it has froze where there was less than one minute. What can I do to wake it up. I have done a couple of hard shutdowns with no luck. Thanks
Welcome and Thank you too.
Do come back to the ASC Forums, in the future, if / or when additional question may arise
