Software migration and updates for an unused 3-year-old iMac
Bought an iMac 3 years ago. Never been used.
It's about time to put my current iMac to rest. Am I going to face a software nightmare trying to migrate from the "old" system to the new one? What would be the best protocol for handling this situation to ensure the OS and applications are uptodate?
iMac 21.5″, macOS 13.7
