Accessing the RAM requires the removal of the internal frame.

  1. Power down your Mac mini, disconnect all of the cables, and flip it over.
    • Power down your Mac mini, disconnect all of the cables, and flip it over.

    • Insert the Jimmy into the crack between the aluminum top housing and the plastic lower housing.

    • The Jimmy should reach a stop about 3/8" down.

  2. Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount.
    • Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount.

    • There are several plastic clips on the lower housing that fit into a channel in the aluminum top housing. Your goal is to use the Jimmy to push these clips inward enough to free them from the channel, while gently pulling up on the lower housing.

    • Once you have the first side free, rotate the Mac mini and start prying up on the front edge.

    • Use the same prying motion to both bend the clips inward and lift the lower housing up out of the top housing.

    • You may need to move the Jimmy along the edge to pry up all of the clips. Be patient and do a little bit at a time.

    • Keep working around the perimeter, freeing the clips along the final edge.

    • Flip the Mac mini back over and lift the top housing off of the lower housing.

    • In the next few steps you will be removing the AirPort and Bluetooth antennas (shown in red) from the internal frame. Be very careful, as breaking the brackets will require replacing the internal frame.

    • We will first remove the AirPort antenna, located in the lower left corner of this picture.

    • Slightly squeeze the two retaining arms toward each other and lift the AirPort antenna off its post.

    • Squeezing the two posts excessively will surely break them off the internal frame. Work delicately.

    • During reinstallation, you will have to slightly squeeze the two posts together so they fit into the openings on the AirPort antenna board.

    • The two Bluetooth antenna boards simply lift off the internal frame.

    • Grab the Bluetooth antenna nearest the port side of the computer by the edges of the board and pull it straight up off the internal frame.

      • Pull carefully, as it may offer significant resistance and release suddenly.

    • Remove the antenna board near the front of the mini by pulling it straight up off the internal frame.

    • If necessary, remove the piece of tape securing the antenna leads to the internal frame.

    • Be sure to keep track of the springs under each of the three antenna boards.

    • Use the flat end of a spudger to pry the audio ribbon cable connector up off the audio board.

    • Remove the following four screws securing the internal frame to the bottom housing:

      • Three 6.7 mm Phillips #00 screws

      • One 9.5 mm Phillips #00 screw

    • The screw in the lower right corner of this image is recessed deep in the internal frame and longer than the other three screws. A flashlight and a thin screwdriver aid in removal.

    • Lift the internal frame off the bottom housing, starting at the rear edge, until you feel the concealed edge connector on the motherboard disconnect. Then lift straight off, minding the bluetooth and 802.11 antenna cables.

    • When reassembling, the wifi antenna wire routes to the inside of the vent and then over the top of the vent.

    • Simultaneously pull the tabs on each side of the RAM chip away from the center of the chip. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

    • Pull the RAM chip directly out from its connector.

    • If there are two RAM chips installed, repeat the above procedure for the second chip.


To reassemble your device, follow these instructions in reverse order.

if you are upgrading to 8g it may not work. my system would only recognize a mismatched 4g and 2g for 6g. even the 2g boost from 4g made some speed improvement

Well done! Easy to follow and thorough! Took me 10 minutes start to finish!

You probably need to install Mac Mini EFI firmware update 1.2:

Wife has the Late 2009 Macmini (MM) originally with 2GB. We upgraded to 4GB a couple of years ago, and it has been running very slow with Yosemite (10.10.5) for far too long.

Ordered the 8GB upgrade kit and set for 2 day delivery. Bummer it came in 1 day via UPS. Thanks for the surprise iFixit. The tools were unnecessary for me (as I have most), but they are totally outstanding and the real deal. So I decided to use them all. ;)

The upgrade took about 15 min (even for this experienced Mac repair guy). Fired it up and the MM recognized all 8GB. It doesn’t scream, however, it is probably 2-3 times faster and can handle the amazing multi-takser that is my wife; 16 Safari pages, Mac Mail, Calendar, and 7 other apps open at all the same dang time. Thanks iFixit for the absolute best in repair universe parts, service, tech commitment, and guides.
