Recently, I've been having serious heat issues when running InDesign and Photoshop CS5 in Lion. I'm on a 17" early 2009 MacBook Pro 3.06GHZ Intel Core 2 Duo with 8Gb of RAM, running OS X Lion 10.7.1.
I'd say it was a Lion problem entirely, but checking Activity Monitor, Photoshop and Indesign are routinely grabbing close to 2GB of real memory EACH plus close to 2GB of virtural memory each. This is without having any documents open in Photoshop, working on a 44-page document in Indesign with about 80 images, mostly TIF and a few JPEGs.
Not surprising, Indesign choked, gives me an occasional "Out of Memory" warning.
The only other apps open at the same time were mostly small fry, like Numbers, BBEdit, iCal, HoudaSpot ... and Time Machine.
Suggestions? Ideas? Any magic Cache files I can dump to clean things up?
Those have had quite a few lion heat issues beyond indesign. If my memory is correct that is one of the first models to feature two GPUs that switch between loads, somewhat poorly compared to the new ones also.
Check out http://codykrieger.com/gfxCardStatus this guy and see if you can spot it swapping to graphics modes. Choosing the lower end graphics could alleviate your heat issue.
Thank you, macinbytes. I'll try it. Sounds like a great app.
