Hi Joseph and the crew;

I have a brand new (couple months old) 15” MacBook Pro w Retina (16GB RAM, 2.3GHz) and I can actually repeatedly crash it just by running Aperture in a full screen mode and flipping through the photos. It appears as if it was running out of RAM and not releasing it back. I have all the latest updates installed (always) and I know this is not related to my machine since within the first week of having it I noticed a dent on my screen and Apple sent me a brand new machine. I could replicate this behaviour on both machines. 

To mitigate the restarts, I use FreeMemory Pro set at “freeing” RAM once it drops to 4GB but if I push the Aperture too fast (and I do not mean major editing but just simply going through many photos in full screen mode, viewing them), I still crash it. 

I was wondering if there is anyone else with something similar and if you have any tips. I will post this on Apple forums as well and report it to Apple.
