Right now I need a clean install Lion. But my mbp was pre-installed Lion when I purchased it. I use some trick from google to option - click in app store but can't find the Lion. Tried download Lion from recovery disk, downloaded but It can't install for some reason. Can someone help me in this case? Ps: if I download the installer from torr*** or others source, can it use Xcode and else from apple? If it is, Should I upgrade to mountain lion (wanted to buy but only paypal in my country, and apple didn't permit that)? Thanks!
