Trying to downgrade OS on iMac from Monteray to Sierra. Error message when installing "Error occured during installation. Try again." Tried 3 times. What's going on and soluition?
iMac 27″, macOS 12.6
Did you erase the drive to MacOS Extended Journaled?
APFS format won't work for Sierra.

I'm flattered that you think I'm computer savvy enough to know how to "erase the drive to MacOS Extended Journaled"....but I am not.
Would you line out for me the steps that I need to follow for that procedure?
I appreciate your help.
FWIW, it doesn't make much sense to downgrade a supported version of macOS to a version that is no longer supported. Is there some compelling reason you would want to?
I see many reasons. :)

I guess if you don't want to run current versions of software from Adobe, Microsoft, and oodles of others. 😎
Good question. I want to be able to work in and open previous inDesign and Photoshop Element files. This will be my backup computer as well as being used for those applications.
Yes it does. Many thanks.
Great news my friend, take care. :)
