The usual port doesn't exist on this @#&*($^ machine so I either have to take the thing apart and void the warranty OR bring it to Apple along with my car, many dollars and likely my first born child to have them do it.
Can't figure out what OS I'm running, but it's not Catalina - based on the little I know and what I've read here, that would be a bad upgrade for me.
Not sure if an external SSD would help? I have one of those lying around? Input and an idiot proof guide on how to make it happen would be appreciated.
