I've started down the path of tinkering with my Android phones. What's curious to me is that during the bootloader unlocking process if you're on Windows you are required to download and install drivers while on OS X or Linux drivers are not required. Why is this?
I haven't tried it myself, but these directions from androidcentral make no mention of the Samsung driver.
And looking at the bottom comments, it looks like some people do, some people don't.
My guess is it depends on your system configuration.
