The Genius Bar people can reset the firmware password but they will need a proof of purchase for the original purchase. I have the same problem with a MacBook my college roommate gave me and they told me he has to provide them with the original proof of purchase (or the credit card he used to buy it since he bought it at the Apple Store) in order to unlock it.

Does this work on an A1502?

Oops. Just saw Pablo Guerrero’s July 11 post and Eric Drummond’s August 19 reply. I will reinstall the thermal sensor.

Thanks for a great guide!

I want to replace the 3.5” hard drive with a 2.5” hard drive. I bought the Sabrent 3.5-Inch to x2 SSD/2.5-Inch Internal Hard Drive Mounting Kit (I actually have two of these iMacs and will install a 1TB HD in one and a 500GB SSD in the other). Do I have to install the thermal sensor as in steps 18-20 if I’m using a 2.5” drive/SSD?

Thanks in advance.

Thanks, Sam. How can I tell for sure if I need to replace the digitizer as well or only the glass? As I said, the iPad seems to work perfectly other than the shattered glass.

My son dropped our iPad Mini 2 and the glass shattered. Other than that it works perfectly. My question is, do I have to replace the LCD or can I just buy the glass (much cheaper, around $20) and replace that? It seems that repair would be much simpler as well. Thanks in advance.

I think you're missing this step: With the iMac lying on its back screen facing up, grasp the aluminum sides of the bezel and carefully pull it straight up. Then disconnect the microphone cable. Took me a while to figure it out.

OK, so the airport wire is short and the only place it looks like it goes is in the right side socket closest to the rear of the unit, also taking in account the kinks in the wires. I'm going with that but would appreciate if anyone can confirm. Thanks.

PS: I found this page about antennas (Mac mini Model A1283 Antennas Replacement) but the wire colors they mention are different.

I have a dual-drive (mirrored RAID) A1283 which I bought as a preconfigured Snow Leopard Server. The optical drive was omitted to accommodate the second drive. I have to replace both drives. I've been able to disassemble the machine fine but now all 3 of the antenna leads have become disconnected-- both Bluetooth antennas and the Wifi antenna. I can't figure out which goes where. The little board with the barcodes on it has three antenna sockets. With the back of the Mac Mini facing away from me, the Serial Number info reading correctly and the 3/8 inch wide copper ribbon cable on the left, there are two sockets on the right side and one on the left above the copper ribbon cable. My question is, which goes where? The plugs and sockets are all the same. The wires are as follows: Bluetooth closest to the back of the case, black/light blue; Bluetooth closest to the front of the case, silver plastic sheath; Wifi right rear corner closest to the back of the case, black and brown. Thanks in advance.
