I have taken apart quite a few laptops but this is my first Mac. This confirms my statements, to anyone that will listen, that these are the most "exquisite" machines ever produced. I just performed these HDD Replacement steps and with appropriate fear and trepidation popped the clips off. It would have been very helpful if someone had mentioned that they come straight up. I wasn't sure so I wiggled and (carefully) pried with the spudger until one of them went "POP". The credit card idea was helpful but my card was pretty soft so I didn't dare use it with too much force. When I got the top cover loose I just leaned it back against the screen so as not to take a chance on damaging the cable. Reassembly was according to the notes, but again the spudger was perfect if inserted into the drive slot (careful on the felt!) to support the base of the clips. Thanks to all for the notes. BTW; Prayer helps!
