Believe it or not, there is actually a cheat engine for the Intel Mac OS X systems! Personally I didn’t know till I read through the front page.
If you try searching for a mac cheat engine, you will find an older version on other download sites and ports on sourceforge, which do not work on the current Mac OS X operating systems.
Also, there are other memory reading softwares such as iHaxGamez and The Cheat. But, they only find temporary memory addresses with no pointers or offsets. So I highly recommend getting Cheat Engine.
