I have always been on the safe side when it comes to buying authenticated apps and software. Never jailbreaked my iPhone/iPad; and never ever used cracked mac software. But I landed my macbook pro (running lion) to my brother which he used in a roadshow for about a month on the run. When i got it back it had an Adobe CS 5 photoshop in it. My brother said he essentially needed and cracked it... Anyway, i will be pleased if we can skip the moral side and try to have a helping hand. He said he installed it through terminal editing the hosts file by a walkthrough. I immediately uninstalled the software, but how can i turn my hosts file back to the original. Please help me out. He said he used this walkthrough to proceed: INSTRUCTIONS: ------------ 1.Extract the files. 2.Run Setup, Install as trial. 3.Make shure photoshop is closed. 4.Open the 'Terminal' application and paste the following: sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts 5.
