How to Boot into Recovery Mode
It seems as though there is a different way to boot into recovery mode based many different things about your Mac and I cannot remember mine. I have an iMac that I bought in May of 2023. It's an M3, 8 GB, now running Sequoia 15.6.1.
I have 2 back up disks that won't record backups and Disk Utility won't work in regular mode, so I am hoping that it will work in recovery mode. It seems unlikely that it would be a disk problem since the problems are happening at the same time.
I checked the Internet, but there are so many ways of getting into recovery mode that I simply do not know which one is appropriate for my iMac.
