Hi guys. I'm in a bit of a pickle here and need your help. I've got a Macbook Pro 2.53ghz (late 2008 unibody), 8gb RAM, Lion 10.7. Yesterday I did some heavy Photoshop+Aperture work which maxed out my 8gb RAM and scratch disks as well, and the system suggested I force quit some applications. I did that, and rebooted my system. Afterwards everything was back to normal and Photoshop and other apps were back in full effect. BUT! Now, whenever I start up Aperture (3.1.3), it starts processing an image (the process apparently got cut off when I used force quit earlier), and it maxes out my RAM and the system becomes unresponsive and fans scream at 7k rpm. This happens every time I startup Aperture. I can't do anything, I can't even cancel the processing task in Aperture, it says "canceling" but nothing happens. I need Aperture to work and I don't know what to do, everytime I start Aperture the system becomes unresponsive. Thanks in advance! EDIT: Solved, thanks to psxguru!
