I just purchased a Galaxy Tab 8.9 and would like to root it. I have been reading for the past couple of days on how to get my device rooted. I have found instructions on how to root through a PC. I am wondering if the same instructions would work on a Mac. All of the instructions point towards connecting the tab via USB and my mac won't allow it to go into mass storage mode. I have also tried downloading a zip file from another post and when trying to flash it says "signature verification failed." Do I have to use a PC or is there a way that I can use my Mac? I'm super new with Android so any help would be nice. Thanks in advance.
