I just bought a new Mac and I'm manually migrating everything over given that it's been a while since I did a clean install and that the new Mac has less storage than my existing one. I will be wiping the old Mac after I do the migration.
However, I have about 600GB worth of Time Machine backups for the old Mac on the NAS which I'd like to shrink to make space for Time Machine on the new Mac. I just want the latest Time Machine backup to serve as an archive in case I forget to move some files when I wipe the old Mac.
Is it possible to (easily) delete all but the latest snapshot of the Time Machine backup?
