I am trying to clean up my iMac as it's struggling a little. In an idle state I notice in activity monitor that I have 2 entries both called "Adobe CEF Helper", one taking 28.5 mb (Intel) real memory and the other using 14.4mb (Intel 64 bit). Additionally I have Adobe Creative Cloud using 54.6 Intel memory. Is it possible to pause these and then manually update Photoshop, Lightroom, and Illustrator as and when I can? I have an iMac that is 6 years old running Lion OSX 10.7.5 and with only 2.5gb memory so I realise image manipulation with these apps is going to slow it all! The max memory my iMac will take is 3gb so I'm near to that. I have repaired permissions so is there anything else I can check?
