How to Upgrade the RAM in an Apple Mac
Mini
Mac Mini RAM Upgrade Tutorial
Want
to upgrade the RAM in your Mac Mini? It's definitely a good idea if you have an older Mac
Mini
that you want to get some extra life out of. RAM always makes an old machine a little faster. Or, you can definitely save a
few bucks by buying a new stripped down
Mac Mini
and upgrading the RAM
yourself later.
But before you can install that extra RAM, you'll need to take a walk
down to your local hardware store and grab a couple putty knives. Thanks
to the Mac Mini, the putty knife is now becoming part of the standard
set of essential computer hardware tools.
Traditionally, Apple computers
have easily come apart with a few screws and levers. In fact, some
Apple
machines, like the PowerMac G5, almost come apart entirely
without tools. However, brute force, patience and a
putty knife are
required to crack open the Mac Mini.
Many
people speculate that Apple made opening the Mac
Mini difficult on purpose. Apple would prefer that you let an authorized Apple service
provider handle all hardware upgrades and part replacements with
their consumer level products. While we're on the subject, please
keep in mind that if you ruin your computer while trying to open
it, Apple will not replace it for you. Also, don't come complaining
to us. Any damage you inflict on your computer is your fault, not
ours.
Proceed at your own risk
and before you begin, you might want to consider backing up all important
files. Better safe than sorry.
Requirements:
putty knives ($0.86
plastic putty knives are recommended if you hate scratches)
fingernails
standard size regular
head screwdriver
small Phillips head
screwdriver (magnetic if possible)
RAM (DDR2 SDRAM)
shot glass or cereal
bowl
static wrist guard

Do you have a PowerPC or Intel Mac Mini?
06) Congratulations 1st
generation Mac Mini owners. If you have a Mac Mini with a PowerPC chip you can skip this step because your RAM slot is unobstructed.
However, Mac Mini Intel owners will have to remove the AirPort
card antenna, upper chassis and a tiny cable before getting
access to the RAM slots.
Take a quick
moment to look at the image below and familiarize yourself with the
inside of the Mac Mini and locations of specific parts.
Removing the 4 Corner Screws
To remove the
upper chassis, which holds the hard drive and the
CD/DVD drive, you will need to take out 4 corner
screws (3 small screws and one big one)
surrounding
a black plastic chassis. We suggest a magnetic screwdriver.
Getting the 4 screws in and out is very difficult without one.

NERD NOTE: All Intel Macs, including the Mac Mini, work better when the RAM is equally paired (i.e.. two 512 MB RAM chips work better than an unequal 512 and 256 MB pair). |
the Mac Mini
Print out this tutorial
so you can refer to it later if needed.
01) Find a flat, clean, sturdy and dry surface that you can use for your Mac Mini's "operating table". Your kitchen table will probably work nicely. Some bad work-surface examples include: a diving board, the ball pit at Chucky Cheese, and a sauna. You should also try to reduce the chance of static shock in your surroundings by not standing on carpet, not wearing a cell phone, putting on a static wrist guard and repeatedly grounding yourself. |
02) If your computer is on, then shut it down. Unplug every cable that's connected to your Mac Mini and carry it over to your operating table. Then flip the Mac Mini upside down. |
03) Use your fingernails to slightly pry apart the top case of the Mac Mini. Using a metal putty knife will almost guarantee a few scratches that can be avoided simply by using your fingernails. If you have a friend helping, have them try to insert either a putty knife or flat-headed screwdriver into the gap created by the fingernails(s). It's a very tight fit and will require some elbow grease and finessing. You can also try using rulers if your plastic putty knife isn't thick enough. Be careful not to dig the putty knife in too deep or you will tear up some of the gray foam on the inside of the case. Opening the Mac Mini is not an easy task. Turn back now if you don't feel comfortable. |
04) Once you have the putty knife inserted into the side, use it to carefully pry the top case apart from the rest of the Mac Mini. You may have to push back until the putty knife starts to bend. Don't be alarmed if your Mac Mini starts to snap, crackle and pop like a bowl of Rice Crispies. This is the sound of the plastic clips and metal rim coming loose. Also be aware that minor scratches in and around your Mac Mini will be pretty difficult to avoid [see image]. But a plastic putty knife will dramatically decrease the amount of scratches your Mac Mini will suffer during this procedure. A plastic putty knife is only about ¢0.80 from Amazon.com or your local hardware store. Once you have loosened the top cover, carefully slide it off. |
05) Be careful and take your time. Here's a video of us removing the Mac Mini cover. |
06) Congratulations 1st
generation Mac Mini owners. If you have a Mac Mini with a PowerPC chip you can skip this step because your RAM slot is unobstructed.
However, Mac Mini Intel owners will have to remove the AirPort
card antenna, upper chassis and a tiny cable before getting
access to the RAM slots.
Take a quick
moment to look at the image below and familiarize yourself with the
inside of the Mac Mini and locations of specific parts.
A: RAM slots - hidden from view B: infrared receiver - at the end of the optical-drive slot C: Bluetooth antenna D: AirPort antenna E: Bluetooth card - beneath and behind the AirPort antenna |
To remove the
upper chassis, which holds the hard drive and the
CD/DVD drive, you will need to take out 4 corner
screws (3 small screws and one big one)
surrounding
a black plastic chassis. We suggest a magnetic screwdriver.
Getting the 4 screws in and out is very difficult without one.
IMPORTANT: At first glance you'll notice what is essentially three "levels" of screws. The first or top level holds the metal lid on top of the hard drive... leave these alone! The second or middle level holds the hard drive to the black chassis... leave these alone as well. The third or bottom level of screws are what need to be removed. These are the corner screws. |
10) The next step is to unplug the tiny cable next to the battery. Your Mac Mini has what looks like a giant watch battery inside. To the right of this battery is a tiny black cable plugged into the main board of the Mac Mini. Gently pull upwards on the cable and it will pop out of it's socket. If it doesn't pop out, try to gently lift or pry it up from the plastic connector using a a small flat head screwdriver. Don't pull the wire too hard or it will rip out and you'll be screwed. Finding someone to replace and install this part will be very pricey. When putting the Mac Mini back together, don't forget to reattach this tiny plug. It's a bit of a no brainer but I bet someone out there will forget! |
11) Properly bracing the upper chassis is very important. After you've removed the 4 screws and the tiny cable next to the battery, the chassis can be removed. Gently lift the chassis straight up - pay close attention to the wires and the daughter board. This sounds more ominous than it actually is, just be careful. Flip the upper chassis over, it should still be connected by a few wires in the back. At this point you can either ask a friend to gently hold the upper chassis in place while you insert the RAM or you can rest it on a book or box. Don't rip the cables or you'll be screwed. |
12) Sticking the RAM into place is the easy part. But before you touch anything inside the computer, make sure you are static free. Touch the metal cover on the inside of the Mac Mini top cover. If you are replacing RAM, grab the tiny metal hinges, spread them apart and gently pull out the RAM chip(s). Insert your new RAM at an angle and push it down until it snaps into place. |
13) Before you put the Mac Mini back together, you should power it on and test out your new RAM. The last thing you want to do is put the cover back on, find out that the RAM wasn't seated properly, and then have to take it apart again. Remember several internal components of your computer will be exposed while the top cover is removed. Please be extra cautious. |
14) Zap the PRAM! It's a good idea to zap the PRAM whenever putting new hardware inside your computer. If you forget the zap the PRAM, you computer will probably boot up and present you with a folder icon and question mark warning. There are 2 ways to zap the PRAM: OPTION A - Loosely lay the cover back on. and make sure there are no exposed areas where you could electrocute yourself. Safety first! Then carefully plug in all the cables and turn on your computer while holding down the following keys: P, R, Option, Apple. You should hear the Macintosh startup chime. Don't let go until you hear the chime ring 3 times. This is called "zapping" the PRAM. OPTION B - You can also reset the PRAM before closing up your computer buy pressing down a little black button inside the Mac Mini. It looks similar to the Airport Antenna and is in the opposite corner after the lid is removed (see image on right). I usually call it a doorbell and people know what I'm talking about, but the "doorbell" is actually called the SMC switch (System Management Controller). Do NOT press it or handle anything inside your computer while it's plugged in. You could electrocute yourself. Press the doorbell while the computer is unplugged and make sure you are grounded first. One static shock could kill your computer. If you can't find the "doorbell" then just use the startup key combination listed above. If your computer starts up fine, then checkout the About This Mac window under the Apple menu. Everything look OK? The About screen should indicate the presence of your newly added RAM. You can click on the "More Info" button to see the status of each chip. If everything looks good, Shutdown the computer, unplug all the cables and go to the next step. If you ran into any problems, then try some of these RAM troubleshooting tips. |
15) If the RAM is good and everything checks out, then you can put the Mac Mini back together . Shutdown the computer, unplug everything and bring it back over to the operating table. Return the 4 corner screws back into place. Remember the big screw goes in the front right corner of the Mac Mini. Snap the Airport antenna back into its two plastic clips Don't forget to reattach the tiny plug. As far as the top cover goes, We've heard people say this next step is either very easy or really hard. We just carefully lined up the cover and gently pushed it back into place all in one motion. Easy. However, we can see how putting the cover back on so the metal prongs line up is pretty tricky. If you put the cover on only to find a gap or two showing around the edge of the Mini, then you will have to pry it open and try again. It's a tight fit and will require some patience. |
