Install the new memory

Disconnect the power cord and all other cables from your Mac mini.

Lay your Mac mini upside down on a soft cloth or towel, and then rotate the bottom cover counterclockwise to the unlocked position.

Remove the original memory modules

Press on the cover to pop up the opposite side, and then remove the cover. Gently spread the clips at the ends of the top memory module just enough to let the free edge pop up.

Replace the bottom cover

Pull the module out of the slot. Repeat to remove the second, bottom module. Carefully press the notched edge of the new memory module into the bottom slot while keeping the opposite edge slightly raised.

Remove the bottom cover

Press down on the raised edge until the clips snap into place. Repeat to install the top memory module.

Don't connect the power cord or turn on your Mac mini until you replace the bottom cover. Never operate your Mac mini without the cover in place. Replace the bottom cover using the alignment dots to place it in the unlocked position.

Rotate the cover clockwise to lock it in place.

  1. Reconnect the power cord and any other cables you disconnected.
  2. After you install the memory, confirm that your Mac mini sees the new memory.

    To remove or install memory in the following Mac mini models, go to an Apple Authorized Service Provider.

  3. To check that the computer recognizes the new memory:. Start up your computer.
  4. When you see your desktop, choose Apple menu , then choose About This Mac.
  5. Confirm that the memory listed matches the memory you installed.

    If the reported memory size isn't correct or if your Mac mini repeatedly plays three tones, it may be having trouble recognizing a memory module.

  6. If this happens, shut down your Mac mini, verify the module specifications against the requirements for your Mac mini model, and then repeat the memory installation instructions to make sure that the modules are installed correctly.
  7. If you still have issues, remove the memory and consult the support information that came with the memory, or contact the vendor who provided the memory.
  8. I have a Late 2012 Mac Mini running MacOS Sierra. I'm using it as a media server and DVR (Channels DVR) and now would like to also run Docker on it for some related capabilities.

    I need to update the OS to Catalina, which according to everything I fan find it supports.

  9. If I go into the App Store and select Updates, its not showing a MacOS update available.
  10. My understanding is that is where it should show up.

    I also tried searching in the App Store for MacOS Catalina and it brings up Big Sur, which this Mac doesn't support.

  11. How can I do this update?
  12. EDIT - I think Mojave would also be OK for Docker, so that would work too.Thanks.
  13. Pull the existing hard drive clear of the Mac Mini.

  14. Detach the Torx T8 screws from the existing hard drive.
  15. Attach those same screws to the left-hand side of your new SSD.

  16. Detach the ribbon cable from the existing hard drive.
  17. Connect the same ribbon cable to the new SSD's SATA connectors.
  18. Turn the SSD over so it's upside down and the screws from step 15 are facing the edge of the Mac Mini.
  19. Using a business card again for support, slide the new SSD into place until the screws lock into place on the bracket inside the Mac Mini.

  20. Reconnect the ribbon cable to the logic board.
  21. Reassemble the Mac Mini reversing the steps above, first installing the black shroud, then the fan, then the wireless shroud.
  22. Line the markings on the base up with the corresponding markings on the Mac Mini.
  23. Twist the base back into place.

One additional thing to do throughout this process is to use some canned air to blast out any dust. You'll be surprised at how clean the inside of a computer this old is, but it never hurts to clear it out while you're inside.

All the parts you need to easily add a second hard drive to your 2012 Mac Mini, including the all-important ribbon cable and logic board removal tool.

Better than using your fingers, this pry tool kit is worth having in your tool kit for those hard to remove and tiny parts.

Not everyone will want to do this, but it is possible to install a second drive in the 2012 Mac Mini to maximize its storage potential. You could reuse the existing hard drive, but since it's over six years old, it makes much better sense to use a fresh one.

You can use either a hard drive or an SSD, or as we have here, a Seagate Firecuda hybrid drive, not unlike the Fusion Drive Apple uses in some of its machines.

  1. Follow steps 1-17 from the section above to remove the existing drive and prepare your new SSD boot drive.
  2. You will need to detach any remaining items from the logic board at this point, including the wireless shroud and the IR cable.
  3. Grab your second drive install kit.
  4. Remove the final screw from the logic board with a Torx T6 screwdriver.
  5. Insert the logic board removal tool into the holes pictured.

  19. Re-attach both by screwing the T6 screws back into the case.
  20. Reverse the steps above to reinsert the logic board, all fixings, and connectors, including the new hard drive ribbon cable.
  21. Follow steps 18-23 from the section above to insert the new main SSD and reassemble what remains of the Mac Mini.

Once everything is back in place, and the Mac Mini is closed up, it's time to do a fresh install of macOS.


You could clone the existing drive and skip this step; however, when doing any kind of work this extensive, we always find that doing a fresh install of the OS is a good idea.

The process is pretty straight forward.

  1. Turn on the Mac Mini.
  2. Press CMD+Option+R to enter Internet Recovery mode.

It'll take some time, but you'll now download a factory-fresh version of macOS from Apple and use it to set up your Mac Mini again from scratch.

On your new drive, you will need to use the Disk Utility feature to first erase the SSD (even though it's blank) and then create a new partition to install macOS on to.

From here, run the install process for macOS and leave it while it does its thing.

Maxed out

Crucial 16GB RAM kit

Max out the RAM in your 2012 Mac Mini

The most you can install in the 2012 Mac Mini, 16GB of RAM is a great performance upgrade, and this kit from Crucial will slot right in.

Besides adding an SSD, the next best thing to do to give your old Mac Mini some additional legs for present-day computing is to add more RAM.

The 2012 Mac Mini uses 1600MHz DDR3 SODIMM modules and can accept up to 16GB across two slots. So the best you can do is grab a 16GB kit made up of a pair of 8GB sticks.

Here's how you install it.

  1. Flip over the Mac Mini.
  2. Place your thumbs in the circular divots and twist the base clockwise.
  3. The base should simply pull away, but may need prying with a plastic tool or even a credit card.
  4. Pry apart the metal brackets around the current RAM sticks.
  5. As they pop up, gently pull them away.
  6. Line up the new RAM sticks and push gently into the slots.
  7. Push down gently until they lock into place.

To verify all is well, boot up the Mac Mini and check out the About This Mac information. If it shows the amount of RAM you installed, all is well. If not, you'll need to go back in and troubleshoot your installation one stick at a time. Remove one, reboot, and check About This Mac again to verify.

By doing it a stick at a time, you can easily identify if you have any bad RAM. If this is the case, the system won't post, so it's easy to spot.

Pair it with a good monitor

AmazonBasics miniDP to DP($11 at Amazon)

Use one of these and hook up to a 1440p monitor for high resolution computing every day.

Now you've brought your Mac Mini back to life for the present day; it's worth considering what you're going to use to look at it all day.

The 2012 Mac Mini won't give you a 4K output, but it can handle 1440p but only over a DisplayPort connection. HDMI on this model is limited to 1080p.

But, grab a cheap mini DisplayPort to DisplayPort cable and a great 1440p monitor like Dell's UltraSharp U2719D, you'll have yourself a really fantastic workstation.

Where to find a 2012 Mac Mini in 2021

A new Mac is an expensive thing; there's no denying that. Ultimate performance will always be better on newer models. Still, if you're looking for a really expensive way to get into Mac computing, or want a solid secondary machine, you can do a lot worse than picking up a used 2012 Mac Mini and upgrading it.

Where do you find one, though? That depends where you live, but the usual places like eBay and Craigslist are a great place to start. Don't overpay, though, for one that someone else has upgraded, when you can likely do the work yourself for less.

Whether you buy or already have an old Mac Mini sat around doing nothing, with not a lot of money and a couple of hours of your time, you can turn it into a fantastic little computer to use in the present day.
