Every mac has it,
search for it by clicking on the magnifying glass in the top right corner.

–Not sure if you need to use iRecovery for mac users though.

I was able to downgrade from 3.1.2 to 3.0 using Windows, however when following this video you don’t have to download iRecovery or access it in the command prompts or terminal. All I did was follow what he did until the iRecovery part and then run redsn0w to unlock and jailbreak the iphone ( i have a iphone 2.0- 1st gen).

Sorry i removed last comment by mistake, yes it will work as long as your device is a 3G not 3GS.
thanks
