Hi, I own a early 2008 Black MacBook 3,1 2.2 GHz Intel Core 2 Duo, 1GB Memory and a 160GB HD. I recently put all my photos and music onto an external HD, and now have 90GB of free space. As part of the same operation I updated to Snow Leopard. It is now running quite slow. Not unfunctionally slow but definitely not what you would expect from a full clean out, an extra 40GB of space and a new system. I can't remember what OS I had before this but it was definitely not this slow. iphoto takes ages to load, I wouldn't even think about putting photoshop back on it and Pages often drags the chain a little too. When I did the new install, I did a big clean up, repaired permissions, etc. Questions: 1. Will extra ram solve all my issues? 2. What are some other options I could look at to speed things up again? 3. Am I best to maybe just downgrade back to leopard? PS: I'm not massive on computer jargon so a little consideration in any helpful tips would be appreciated. Cheers.
