Ok so Next Wednesday I'm taking my MacBook Pro to be repaired at the Apple store. But recently my data got corrupted on my HDD and I had to erase it and now I'm having to reinstall OS X Lion. I thought I could just boot into the Recovery HD and reinstall lion fine that way. But it's giving me an error saying "Can't download additional components" so I can't install OS X. I backed up my data on a external HD but it's over at my cousins and he's on vacation so I can't get it until next Friday. What I'm trying to ask is, Since it won't let me reinstall OS X right now, Can I download OS X Lion 10.7.4 off thepiratebay, mount it on a USB and Install it that way? Will Apple find out that I have a pirated copy causing me to get in trouble?
