Using Aperture 3 with new (2011) iMac
Currently I have been using Aperture 3 with my MBP. My library is on an external drive. When I bought my iMac, I hooked up my drive to that machine and then opened Aperture and I got a message that popped up saying something like my library was 32bit and the iMac is 64bit and I would have to convert my entire library over to be able to use AP3 on my iMac. Does this sound right. I remember it was something along those lines and I ended up not converting all my files and still use my MBP instead.
iMac, iOS 5.0.1
