Around the first of November, I upgraded my iMac to Catalina and the results have been disastrous. Since the upgrade, the computer will spontaneously shut itself down, and sometimes try to restart itself. I've spent many hours on the photo with Apple support, reinstalled the OS twice, run diagnostics on the hard drive, etc. with no improvement.
So, I bought a new iMac, hoping for a quick migration; it was not to be. Multiple attempts using the Migration Assistant failed when the old computer just shut down in the middle of the migration. After a few of these attempts, the new iMac would no longer run!
I've reinstalled Catalina on the new iMac, and have been advised by the Apple tech to use the target disc technique - hold down the letter T while starting the old computer and its hard drive becomes accessible to the new computer without actually starting the old computer's OS. I've finally acquired the necessary adapters and cables (Thunderbolt 2 to Thunderbolt3) and am preparing to move files from the old to the new.
My Lightroom installation is very important to me, and I'd appreciate any suggestions regarding specifically what I transfer to the new computer. My image files are on external drives; I don't need to move them.
Any thoughts will be appreciated!
