I have had my first MacBook now for about a year. Its beginning to slow down quite a bit, which is expected I guess. I have been looking around for ways to speed things up, but I do not know what they mean, how they work, how to do it. I have a MacBook Pro 13in, 2.53 C2D, 4 GB ram, 500 GB hard drive, running 10.6.4. I also have a bootcamp of Win7 64 bit Ultimate but I am not having any problems with that. Apparently there is a way to reinstall the OSX that preserves everything, but a clean install of the operating system. I bought this before Snow Leopard, so do I insert the Snow Leopard disc to do it? I tried restarting and booting from the disc but I must have missed something because it just booted normal. Anyways, advice from those much more wise than I would be much appreciated. EDIT: I ran xBench 3 times after a clean shut down, averaged roughly 138 every time. Is this normal for my specs?
