Cleaning Up Old Mac Before Migration
I have purchased a new MacBook Pro. I currently have a 2007 iMac (running El Capitan) that was set up from my even more ancient MacMini, so I have a lot of very old unused stuff on my iMac.
Since I am not a tech person at all, I was hoping to use Apple's migration feature or install from a Time Machine backup (recommended by an IT friend) to set up my new computer rather than try to do a clean set up and figure out how to get what I want moved over. But I'd like to clean out all the really old stuff on there that I do not use. Is there a recommended app that could help me with that? Or is there a pretty easy way to make sure I delete old apps entirely, as well as hunt for old files/stuff that I would want to delete before migration/Time Machine install?
