I just bought a new MBA and I want to use the same external HD for Time Machine that I used for my old computer. Time Machine works perfectly on my old computer, but when I recently plugged it into my new computer, it started backing up and now when I enter Time Machine on the new computer, I can only see today's backup. The thing is, I can still get to my old files by going Time Machine/backups/old computer/date of backup but it is a pain to do it this way and somewhat unintuitive. How can I restore Time Machine to the way it usually works on my new computer with all my old files?

p.s. Sorry if this gets asked a lot, but I Googled around and all I could find was stuff about Time Machine migrating data between Macs.

Edit: Did some searching on the Apple Communities and found this thread:

Pondini's post is particularly useful. If anyone could add anything that would be great!

I'm pretty sure it separates them on purpose to keep each machine separate. AFAIK there's no way to merge two time machine backups from two different Macs
