  • Use the flat end of a spudger to pry the hard drive connector up from its socket on the logic board.

Edit Step 2  ¶

Edit Step 2  ¶ 

  • Use the tip of a spudger to lift the IR sensor connector up and out of its socket on the logic board.

  • Make sure to pry up from beneath the wires and not underneath the socket.

Edit Step 3  ¶

Edit Step 3  ¶ 

  • Remove the following three screws:

    • One 5.0 mm T8 Torx or 2.0 mm Hex screw (either screwdriver will work)

    • One 16.2 mm T6 Torx screw

    • One 26 mm T6 Torx standoff

Edit Step 4  ¶

Edit Step 4  ¶ 

  • To remove the logic board, the two cylindrical rods of the Mac Mini Logic Board Removal Tool must be inserted into the holes highlighted in red. Inserting instruments into any logic board holes other than the ones highlighted in red may destroy the logic board.

  • Insert the Mac Mini Logic Board Removal Tool into the two holes highlighted in red. Be sure it makes contact with the top side of outer case below the logic board before proceeding.

  • Carefully pull the tool toward the I/O board. The logic board and I/O board assembly should slightly slide out of the outer case.

  • Cease prying when the I/O board is visibly separated from the outer case.

  • Remove the Mac Mini Logic Board Removal tool.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • Pull the I/O board/logic board assembly out of the outer case enough to access the power connector.

  • Use your fingers to disconnect the DC-In cable from the logic board.

  • Pull the power cable connector toward the front side of the mini.

Edit Step 6  ¶

Edit Step 6  ¶ 

  • Carefully slide the logic board assembly out of the mini, minding any cables that may get caught.

It may just be my own experience, but the hard drive connectors appear to be "sensitive" to ANY pressure, even when (re)connected properly. I found that I had to repeatedly re-seat them when re-installing the drive, AirPort antenna, and cowling. I would recommend holding off on putting the screws back for the AirPort antenna and cowling until both are in place, and re-checking the hard drive connectors before installing/tightening those screws.

This board component is very delicate, I screwed up my Mac Mini IR receiver and HDD led light by doing this wrong. PLEASE take your time to do this delicately.

I have the same problem. I damaged the connecter for IR Sensor which is on the Logic Board.

Is there a way to fix it?

Michel,

Yes, this is extremely fragile. A couple of the pins on the logic board broke off. They are very tiny pins that are secured to the board surface with solder. I was very careful with it too, but they broke nevertheless. There is no repairing that when it happens. Thus, I have no IR sensor (which I never used) and no front LED (minor loss - not worth the cost of a new logic board). Works fine otherwise.

Mannn this part is difficult. Tks for my girlfriend that disconected it for me. Hands of fary!

I also just snapped this off by levering at the wrong point. So this is just for the IR sensor and the flashing light? If so, I'll just ignore it and happily carry on with life without these two features that I never used or noticed! I've been searching for someone who can do the delicate welding to reconnect the 5 pins but if what you say is true I'll stop searching.

Recommend emphasizing even more in the instructions, the potential for disaster!

Hi, I can't remove the yellow screw, I don't even see it (it look like more like on this picture: http://static.macgeneration.com/img/2012...)

So I don't know what to do, I don't want to damage the tread (if there is actually one..) and I can't move the logic-board..

Do you hav any idea?

The "yellow screw" depicted in this picture doesn't exist in the Mac Mini late 2012, at least in mine. Well, to be more precise, it exists but was already removed when the fan was unscrewed (it was actually in the fan).

Jeff Evans,

I found the same as Jeff.

For reassembly, note that the red T8/2mm hex screw doesn't screw all the way down. It is for the bottom lid to slide-lock onto. Don't look for a hole beneath it on the logic board.

If you're in a pinch and don't have time to order the removal tool, you can use two 2mm hex wrenches.

You can also use the probes from a Digital Multi-Meter. Just be very careful not to stab the pointed end into the casing. With a little care, you can get the logic board out.

On re-assembly, when you're putting the HD back in place, before you've pushed the logic board fully back into place, make sure the disk is in the right place for the antenna plate screw holes (step 8/9) or you'll have problems getting the screws back in. I did, and had to back up a few steps to realign the disk drive!

Look at all of the images. Initially, I took the text literally. I pulled the tool straight back without letting it pivot, and without success. I suggest the following additions: "The tool acts as a lever. Carefully pull the top of the tool down and toward the I/O board. The logic board and I/O board assembly should slightly slide out of the outer case."

You can pull the board out about 1cm with the wires intact.

Martin Cleaver, · Reply

While you can remove this pin with your fingers as shown in the photo, putting back in proved frustrating by hand. I finally got out a forcep which allowed me to grab each side of the plug and push it in at a flat angle.

I found way easier to remove the power wire line by removing the hard drive (loose already) first!

When reconnect it on the board, make it when the board is in the middle of the mac, or you will be not abble to do it!

In April, I purchased a late 2012 mini (MD387LL/A) - 2.5Ghz i5 with 500MB hard drive.

It looks like Apple now secures the drive to the tray with 3 screws. 2 on back side and one on front. This means the entire drive tray has to come out to remove the drive - it no longer just "lifts out" as in step 18. In order to remove the drive tray, you have to remove the power supply (step 22).

During reassembly, watch the power harness and connector from the power supply when reinserting the logic board assembly into the case. When the board is close enough for the connector to reach, re-attach it before inserting the board the rest of the way. I found that if the connector is lined up properly, it almost attaches itself.

Also be careful of the hard drive and IR sensor connectors.

UNSC Jon 117, · Reply

Also, when you're re-assembling (especially with a tight squeeze if you've got dual drives), be sure that the internal AC power connector matches up in profile with the port outline on the rear plate of the main logic board assembly. If the two aren't mated identically, the black port plate won't mate flush with the aluminum case.

johnkimmel,

Speaker trademark? Is it a sony, or a Bose...

I think it is a bad quality speaker.What do you thick?

Does anyone know if the airport/bt board from a mac mini late 2012 can be retrofitted to the 2011 mini? this would add the airdrop functionality to the older device in theory and I have seen a similar procedure performed on MacBook pro's
