Hello, I have an imac late model 2009 with 8gb RAM that is currently running Snow Leopard and I have a Macbook Pro Retina with 8gb RAM running Mountain Lion. The difference between the 2 operating systems in terms of memory usage and optimization is HUGE to say the least... I have to really try to get my iMac to use 4gb RAM in Snow Leopard. In Mountain Lion it is just a piece of cake... This is -as many have said- stupid. I can understand that ML is a more advanced operating system that would require to allocate some more RAM for various tasks, but having safari web content use 2gb of RAM is downright retarded and unecessary. My question is this. Since I havent been monitoring the way apple handles memory optimizations, can we expect something in the forseeable future with an update to address this issue? Can we expect apple to optimize mountain lion memory usage and fix certain apps that really have gone overboard (safari etc)? Thanks for your time.
