Many people will go with cracking an application, disassemble, reversing, use so many tools out there, like otx, and many other to get full version of application (which they can’t afford to buy).
But there’s another way. One brave, wise, and tricky guy went to Apple store, playing with iMac there, opened the application library, wrote down the serial number of the application (that belong to Apple), go home and share it at codez4mac (where I read his story). And it’s a good one!
May be I will try this someday? Another crime?
