I just purchased my first macbook pro and need a little help. It is a great mac with a ton of memory and hard drive but when I purchased it (used) Windows XP was installed on it instead of mac's OS X. However, I do have the original discs to install OS X on the mac. I want to install it and completely remove Windows XP but I dont know really know how to. I tried to research it and ran across something concerning PearPC?? If anyone could please tell me the best way to do the os x installitation and windows removal-step by step please- it would be greatly appreciated!!!
