Hi there, I have a 3 month old MB Pro 13" (2.5 i5 with 4GB) running 10.8.2 Firstly it is incredibly slow to come out of sleep if its been shut for more than a few hours. The grey screen comes up and has a progress bar. If I am just running on battery this seems to not happen. Any ideas? Also certain apps and settings take a long time to load up, especially system preferences, which can take up to 15 seconds to load up. I had a 2007 macbook before this and up until it finally bit the dust it did everything lighting quick. Is this just a symptom of Mountain Lion? Thanks for any replies.
