Transfer of files and apps - without overwriting
I wish to transfer files and apps from a MacBook (2017) to an iMac27 (2019). I do not want to overwrite the contents / wipe-the-drive on the iMac - rather this would be a Copy and Paste scenario. Be advised that for a couple of the apps the original load files are lost, and or the firm is out of business.
Both run Catalina
The MacBook is continually backed up using TimeMachine. Can I use T/M as a means to transfer - without overriding existing files on the iMac?
