I have been having problems with my Macbook (2008, 2.4, 2GB, 160GB HDD) slowing down to a stop. I repair permissions and get 1-3 hrs of normal performance when it happens again. I have a Snow Leopard DVD (10.6.3) and have restarted from that and seem to get normal performance (that's what I'm using now to be on the forum). My system profiler, however shows 10.6.8, but I can use the computer without the slowdown problems (at least for the last 30 minutes). What's happening here? I have recent posts here and have checked Activity Monitor, etc. Nothing looks out of the ordinary. While writing this post, I opened Photoshop Elements 10 and had no problems. Hard drive going bad? And, can I make a DVD for startup purposed of 10.6.8?
