Hi, I have a mac mini purchased 2nd hand off a friend. I've spent a couple of week with it and am using it as a htpc for the most part. What I'm hoping for is to change the 'registered user' information without having to reformat the machine. So the copy of the OS is registered to me, I'd like to do this without reformatting, as I've never installed an os on a mac before and I'd rather keep it working before I dive in and mess something up Also, I use a keysonic wireless keyboard to connect to the mac, does anyone have a list of alternative keys for use with a qwerty keyboard when not using a mac specific keyboard? Or is this something I would need to 'bind' within the mac itself? As you can probably gather, I'm still getting used to my new toy. Thanks.
