I have a MacBook aluminum from late 2008 with 2 ghz intel core 2 duo processor, 4gb of memory and 160gb hard drive. I have been having a lot of issues with it for the past year or so. I just did a clean instal of Mavericks on it and with just the pre-installed programs on it I am still getting the beach ball all the time. That's with none of my files on it. I've checked the hard drive and ram and they all are fine according to the Mac hardware test. I'm to the point of buying a new MacBook but if this one is salvageable I'd be fine with keeping it. Any help would be much appreciated!
