how to turn on iCloud in Photos preferences when iCloud says your mac does not have enough disk space to handle current Photos volume in iCloud. Do not want to optimize iMac....want to keep full resolution pics on iMac.
Mistakenly turned off Photos in iCloud while following instructions for magazine procedure to correct multiple password requests to sign into iCloud. Using Retina 4K 21.5" 2017 iMac with Catalina 10.15.7 installed. Turning off iCloud for Photos means that when you turn it back on, you get a message that says that my iMac disk does not have enough space to accept download for all Photos in iCloud storage. The Photos in iCloud are the identical same Photos as the full res photos already currently on my iMac drive. The process will not proceed without forcing me to accept "optimization" on my drive which will convert all of my full res pics to thumbnail "optimized" size and possibly creating 2 photos for every photo.
Is there a workaround for this problem?
The only thing I can think of is to turn off my backup process, let the "optimization" process from iCloud complete (which takes a horrific amount of time - 600GB of Photos), and then copy the pics from my back up external drive to the iMac drive. Hoping that will not create 2 copies of every photo.
