Just install the game as usual then replace the original "FlatOut 2.app" with the crack.

Then run the game. It will ask you for a name, company and serial so insert any name, any company except for the serial, use EXACTLY this one : FT20-YKMPP-5XZ5-2995

This one isn't an original serial and isn't owned by anybody, so it won't work with the original "FlatOut 2.app" so don't bother trying. It's just the game wants a serial for the first run, so insert this one.

YOU NEED TO INSTALL THE CRACK FIRST BASICALLY!!!!!

Have Fun!
