Root How to install ICS on GT-P1000 unlocked tablet using a Mac

[danibau]

Does anyone have instructions on how to root the GT-P1000 (unlocked version) using a Mac. I have not found any instructions on how this is done using a mac. I've never done anything with android before and I'd like to keep the functionality of my tablet since it is a 3G tablet and am unsure of whether the roms I've found would brick it or leave it crippled if i try to update android.
