I'm having this long-term, annoying issue where Photo Stream won't stay enabled in Aperture after a MacBook Pro restart. As long as I don't restart the computer, things are fine, but once I reboot, then Photo Stream becomes disabled. I've scoured the web for tips and fixes, and have tried them all, and still can't find a real fix. Right now, I'm in the midst of trying the tips on here:
I just use Aperture on one machine and have turned off the Photo Stream on my Apple TV. I've deleted the iLife asset caches and plists multiple times to no avail. Anybody have this same issue?
