I have a 13-inch MacBook Pro Unibody, early 2011. Yesterday, I took delivery of a Crucial M4 and have been eager to pop it in. I picked up a 00 Phillips screwdriver, but apparently I need a Torx T6 to free the HDD. I held off installing the SSD last night for that reason; however, a couple trips and calls to hardware stores today have been ineffectual. Of course when something needs to be upgraded, Apple must require a screwdriver that is hard to come by. Could I possibly get the job done without one?
