It attempted to use ~45 gb of memory to process a 1mb image.feelix 10y agoIt does use a hell of a lot of RAM, but not that much usually. For a 1MP image it'll usually use ~8GB. I think there's something else wrong. What sort of machine are you using? & OSX version?stephenr 10y agoLate 2011 17" MBP. Quad core 2.4GHz i7, 16GB RAM, SSD.
