I have a late 2008 macbook unibody. Since I bought it 5 months ago, it has been a bit slow. Since this was my first Mac and I haven't had a laptop for a while I thought it was just the way it was. The only way I can temporally fix it is to restart the computer. Issues I have been having: After it has been asleep I will wake it up. Shortly after I will be tying in a URL and there will be a 2-6 second delay from when I type the word to when it shows up. I have noticed this in Safari, Chrome, and Firefox. Doing light editing in Lightroom will cause the computer to freeze and not respond for a few minutes. I get the beachball a lot even when just typing, opening programs. Some programs will go in and out of not responding. Steps done to diag: Reinstalled OS and upgraded to Mountain Lion Fixed permissions Verified disc showed ok Replaced RAM Cleared caches Re-installed all programs (did not install from backups) Took to Simply Mac, they could not find any causes of slowness Specs: Late 2008 Macbook 13' 8GB RAM 250GB stock HD (only 55GB used) Core 2 Duo 2.4 I am thinking of replacing my HD, could be having some issues that tech tools nor Disk Utility are catching, but I am unsure. EDIT: Tech Tools did say my spin up time was slow. But after searching it, it could be a fluke.
