I want to transfer the backup files from my old iMac onto my new one. Thought it was time to also get a new external G-Drive. Unable to transfer the backup files from my old G-Drive to my new G-Drive using Finder on my iMac. When I attempt to MOVE the backup files to the new drive, I’m asked to authenticate as the administrator but then told “The operation can’t be completed because backup items can’t be modified.” When I attempt to COPY and PASTE, I only get the second message. Under GET INFO on my new G-Drive using Finder, I’ve verified that “Everyone” has read/write privileges. I’d really prefer to have only one external for all my backups. Thanks for your help.
