Mac mini is Apple's compact yet powerful desktop computer. It has a variety of ports, including four Thunderbolt 3, two USB 3, a Gigabit or 10 Gigabit Ethernet, an HDMI 2.0, and a 3.5mm headphone jack. You can configure Mac mini's CPU, SSD, RAM, and Ethernet before buying. Best of all, you may upgrade its RAM after getting your system. Although Apple doesn't recommend to do so, you can do it with careful work. In this article, I'll explain how to change your MAC mini 2018's RAM.

What You Need

  • A RAM (or kit) compatible with MAC mini.
  • A screwdriver kit with T4, T6H, and T10H bits.
  • Phone opening tool (plastic guitar picks).
  • A tweezer.
  • I know you're not going to do it, but it's better to ground yourself with an ESP Wrist Strap during the process.

RAM Recommendation

Mac mini is compatible with DDR4 (PC4-21300 - 2666 MT/s - SODIMM 260-Pin - unbuffered - nonparity) memories. Since Mac mini doesn't have Intel XMP 2.0 profile for RAM configuration, you should carefully select the RAM to get 2666 MHz speed. I upgraded my configuration with Crucial 32GB Kit (CT2K16G4SFD8266), and it's running flawlessly.

Since Apple recommends doing RAM upgrades at Apple Stores or Apple Authorized Service Providers, proceed at your own risk. Some connectors can be easily damaged, so be careful.

Upgrading Your RAM

You may wish to do the upgrade on a soft surface to avoid scratching your Mac mini.

Step 1: Remove all accessories from your Mac mini, and then power it down. Face down the Mac mini on a smooth surface to avoid scratches.

Step 2: Remove the bottom cover using a phone opening tool. Remove the antenna plate using a T6H bit. There are three big and three small screws. (The plate is connected to the mainboard with a short cable, so be careful lifting it.)

Step 3: Unscrew the metal protector that secures the antenna cable to the mainboard using a T6H bit. Then, carefully unplug the antenna socket from the mainboard. You may use a tweezer to remove the socket.

Step 4: Remove the fan by unscrewing the four screws using a T6H bit again. Be careful removing the fan since it's connected to the mainboard with a small connector. Remove the fan's connector from the mainboard.

Step 5: There are two connectors left. The smallest one goes to the LED connector of the chassis, and the largest one goes to the power supply. Remove them carefully. Take extra care to the LED connector. You may use a tweezer to remove it.

Step 6: Remove two remaining big screws using the T10H bit.

Step 7: Slide out the mainboard. It's the most critical point of the process. There is a small hole between the fan exhaust and the power supply. Using a tweezer, gently pull the mainboard from the hole, or gently push the mainboard from the exhaust. Be careful; the mainboard will move suddenly when it moves out of place.

Step 8: Here is the mainboard of your Mac mini. To access the RAM slots, remove the four screws of the metal covering using the T4 bit.

Step 9: Remove the rubber inserts from both sides of the RAM slots. Remove the RAM modules, and insert your new modules. Once you secured the RAMs, reattach the rubber inserts.

Step 10: Now, reverse the process. You completed the RAM installation.

Your New Configuration

Turn on your Mac mini. Open the "About This Mac" dialog from the Apple menu, and then go to the "Memory" tab.

You should see your upgraded RAM configuration.
