Hello, I just got my first Mac about a month ago after a lifetime of Windows. I have a few questions/problems. First off, starting this morning, my Macbook Pro has been noticabely slower. I have the 2.4 GHz Intel 2 GB 667MHz DDR2 SDRam. The model that was most recently released, baseline. Everything has been sluggish recently, even with few programs open. So, I thought that I'd try and get the thing moving a little quicker. I opened up disk utility and thought that the option "Erase Free Space" would erase those little backup files that get left behind after you delete something from the trash, giving me more space on my harddrive and hopefully let the thing run faster. Amazing, I come back to my computer and see that the remaining disk space has gone from about 80GB to 65!!!! Fantastic, less space! So my first question being how do I reverse that and get my space back, and where the hell did it go???? Second. How do I free up space and make my harddrive a little bit faster, and why is it sluggish right now? Pretty frustrating just because I'm so used to a Windows system where I could fix this in a second. Thanks.
