I'm unsure what to do. I've posted before and clearing my harddrive to give it an extra 100GB of space or so worked temproarily however, the problem is now back. Details: MBP Early 2011, 4GB RAM on Mountain Lion with 150GB free harddrive space of 500GB. Upon a fresh restart, my MBP works beautifully enough opening up all the programs I need very fast. The programs which I have ALWAYS running on mountain lion are: Messages, Utorrent, Facetime, Evernote, Google Chrome, Finder, Mail, Microsoft Word, Preview, Dropbox, MplayerX (idle) and iTunes. These all load up properly and take up about 2.5-3GB of RAM. However, the longer my laptop is on, the more sluggish it gets. Especially after waking from sleep. Just now, Google Chrome crashed and I had to force quit it. I then reopened chrome and it took 20 seconds for it to open again with one rainbow wheel hang. Questions: Is it worth organising an appointment with apple under apple care? Will they do anything about it? My worry with this is the problem takes an hour or two.. or sometimes a day for it to happen. Then after a restart, the problem does go away for about an hour so although its consistent, its one of those things whcih at the apple store they might not appreciate. Or shall I buy more RAM to up it to 8GB? I need my medical videos and music with me at all times so an SSD might be out of the question. Could my harddrive be failing? I find a 2 year laptop to be performing this poorly under the new OS (and it was playing up a bit with lion) really horrendous considering although I have a lot of apps open, I'm not exactly video editing. photo editing or anything heavy.
