I have a 17 inch MPB at 2.3 ghz 8gb ram and a hybrid harddrive. Under OSX SL i had absolutely no problems running any of the adobe products or even apple's aperture. With the update a couple of weeks ago i found that my machine wasn't able to handle iTunes or even finder! cpu temp and fan speeds are at 89C and 6000 rpm continuously. I read somewhere that lion make the GPU run a little warmer but that is ridiculous. The only way i am able to run aperture (took 30 mins to edit a picture) is to close itunes. I tried a GM copy of lion from a friend and that seemed to work nicely with this machine prior to upgrading too lion so i dont know what the problem could be. Anybody have any experience with osx 10.7.1 with this machine?
