Aperture 3 crashes when entering upgrade serial number - solved
Was a bit frustrated after I shelled out $99 to apple for an Aperture 3 upgrade license and Aperture kept crashing whenever I entered the license key they emailed me. Following this thread I renamed my /Library/Application Support/ProApps/Aperture System ID file and everything seemed to work out. That, of course, meant digging out my Aperture 2 serial number which was a bit of a maddening hunt since I bought A2 prior to using YoJimbo where I store all my serials. Anyway, problem solved. Will wait til later today to upgrade my library as I hear that's a bit of a nightmare process as well.
