I have a friend at UofT who wants to transfer to Mac. He has the grades, but he doesn't know exactly what procedure he must go through. Does anybody know what to do?

Not completely sure, but I think you have to apply through OUAC.

He should probably talk to someone at UofT, like their registrar's office on the procedure that he's supposed to take. As far as I know though, it's not difficult to transfer.

yeah, i am trying to do the same thing.
well instead of transferring to Mac, i am trying to transfer to U of T

just apply using the 105 application on OUAC
it's pretty simple. but it was kinda pricey i mean almost $200 just to apply to one other universityy..
