Apple is shrinking! No, not in the AAPL stock way (that's high as ever), but in the 'Let's name everything mini' way. Along with the announcement of the iPad mini on October 23rd (teardown coming soon; we promise) came the new and improved Mac mini, the 2012 iteration of the optical-drive-less mini from last year. With the current trend, we look forward to maybe one day tearing down a smaller version of the Mac mini: the Mac mini mini. But until then, we content ourselves with tearing into the Mac mini Late 2012.

Good things come in mini packages. This mini is packing:
-
2.5 GHz dual-core Intel Core i5 or 2.3 GHz quad-core Intel Core i7
-
500 GB hard drive or 1 TB hard drive configurable to a 1 TB Fusion Drive or 256 GB solid-state drive—upgradable with an extra hard drive or SSD using our dual hard drive kit
-
4 GB, 8 GB, or 16 GB of DDR3 SDRAM
-
Intel HD Graphics 4000
-
Thunderbolt and HDMI ports
-
SDXC card slot
-
-
-
It's beginning to feel like Groundhog Day. The same model number (A1347) has graced the 2011 and 2010 minis.
-
The port layout is consistent with last year's model:
-
10/100/1000BASE-T Ethernet
-
FireWire 800
-
HDMI (HDMI to DVI adapter included)
-
Thunderbolt (supports high-speed I/O and Mini DisplayPort)
-
Four USB 3.0 ports (an upgrade from last year's 2.0)
-
SDXC card reader
-
-
-
A simple twist of the bottom cover and we're in. That is plus one for repairability.
-
Upgradeable RAM!! Oh, how we've missed you!
-
The 2012 iteration of the Mac mini is equipped with PC3-12800 DDR3 RAM.
Macbooks and iMacs are always easy to upgrade for memory..
hahaha the link to twist and shout is really funny! i loved that

We're fans of easily removable fans.
-
Easily accessible fans mean soot sprites better run for cover, because cleaning dirty fans is no problem.
-
Need to clean your fan? Directions can be found here.

-
We remove the fan cowling, eager to get at the Wi-Fi antenna plate.
-
We are really starting to suspect that Dr. Emmett Brown had something to do with this mini as the antenna board and grille look identical to the last two renditions.

Bu adımda kullanılan alet:Mac mini Logic Board Removal Tool$4.99
-
Here we find the legendary Mac mini logic board removal tool in its natural habitat.
You might want to perhaps mention that you cannot fully remove the logic board until you unplug the cable underneath… People need to know that they can only fly the logic board out about a quarter to a half an inch and then need to unplug the cable connecting to the machine.
Hey Eric,
Thanks for the tip! As mentioned above, this is this teardown is an educational first look at the device, and is not meant to be used as a guide. Our actual Mac mini guides have much more detailed instructions for properly completing repairs.
-
-
-
-
The first component off the logic board assembly is the speaker assembly.
-
The speaker cable was arranged in a twisted pair, probably to reduce EMI that could distort the sweet, iconic tones of the Apple startup sound.
-
-
-
The Wi-Fi board, labeled BCM94331PCIEBT3B, stands no chance against our spudger as we make it truly wireless.
-
Removing the EMI shields allows us to peek at the ICs on the communications board:
-
Broadcom BCM4331 802.11 a/b/g/n Wi-Fi chip
-
Broadcom BCM20702 Bluetooth 4.0 transmitter
-
SiGe 5503A 2304A Dual Band 802.11a/b/g/n Wireless LAN Front End
-
SiGe 2598L
-
P2303A TUB2P
-
7871 1228 C6050
Which antenna is for the bluetooth? J0, J1, or J2?
-
-
-
The heat sink is next to go.
-
Apple has really keyed in on their boomerang-style heat sink abilities—and for that, we applaud them. We know boomerangs can be tough to master.
-
Similar, again! We have not tried installing old 2011 mini parts in the 2012 mini, but we are certainly not ruling out the possibility!
-
-
-
A series of screws and tightly wrapped antenna cables secure the rear I/O panel shield to the logic board.
-
A few twists of our precision aluminum driver with a T6 Torx bit and some cable de-routing is all it takes to remove the shield.
-

-
Some mini players on the top of the not-so-mini logic board:
-
Cirrus Logic 4206B Audio Controller
-
SMSC USB2512B USB Hub Controller
-
Broadcom BCM57765 gigabit ethernet and memory card controller
-
Intel L232TB45 Thunderbolt Port Controller
-
LSI L-FW643E-2
-
DELTA 8904C-F Filter
Are you sure that the late 2012 Mac Mini comes stock with a SMSC USB2512B USB Hub Controller? I looked it up and this is a USB 2.0 High Speed Hub Controller. How is this possible when the 2012 Mini has USB 3.0 ports, and 3.0 devices read out as having a speed of 5Gb/s (from Mac's System Profile) when connected to the Mini's USB ports.

-
The rear side of the logic board:
-
Intel HM77 (SLJ8C) platform controller hub
-
Intel V227C254 2.5 GHz dual-core i5
-
SMSC 1428-7 system management bus temperature sensor
-
Parade PS8401A HDMI/DVI level shifter

Hello,
Intel E224B809 platform controller hub
Intel V227C254 2.5 GHz dual-core i5
are not comercial names, what are the comercial names of that Intel chipset and Intel processor?
Regards
The Mac Mini uses somewhat custom parts, they don't have direct counterparts in Intel's main OEM and retail lines.
If you wanted to know what is kind of close, the CPU is very similar to, but not identical to a i5-3210M.
The chipset is much harder to classify, since it doesn't have a lot distinctive features to differentiate it. It's probably similar to the Mobile Intel® HM76 Express Chipset (Intel® BD82HM76 PCH).

-
-
Tucked away neatly near the rear of the mini is the hard drive.
-
Our model came with a 500 GB Hitachi hard drive.
-
The mini is one of the Macs launched with the Fusion Drive.
-
Apple's Fusion Drive is not to be confused with the Impulse Fusion Drive of Star Trek.
Based on the spec of Mac mini 2012, looks like 500GB is not fusion drive, I think.

-
Next up, we displace the power of the mini.
-
It is beginning to feel repetitive to say how repetitive Apple is in the design of the mini; nonetheless, the power supply appears identical to last year's model.
-
Just like last year, the power supply provides 85 watts to the Mac mini—that's the same kind of electric juice as the AC adapter for a 15" or 17" MacBook Pro.
We can clearly see this is an international PSU. Switching power supply, 110-240V, meaning it can be used in Norway, UK as well as USA. Using the proper cord of course, which is so different.
So, are you saying I might be able to run one of these things off a macbook pro battery? I might have a bad battery and want to test.

Mac mini Mid 2012 Repairability: 8 out of 10 (10 is easiest to repair).
-
No proprietary screws are found within the device.
-
You can easily upgrade your RAM and hard drive, as well as add a secondary drive.
-
There's no glue anywhere inside that needs to be removed while disassembling the mini.
-
The CPU is soldered to the logic board and not user-upgradeable.
-
While not difficult to do, you still have to remove almost all the internals in order to replace the power supply.

Hello,
I see that Mac mini Late 2012 have a Hitachi HTS545050A7E362 HDD
What kind of SATA connection have that Hitachi HDD?
And what kind of SATA connection have Mac mini Late 2012? SATA II or SATA III?
Regards
when reinstalling the heatsink did you notice the heatsink does not 100% connect to the platform hub?
even when screwed down tight and new thermal paste applied there is still a paper thin gap between heatsink and platform controller hub
can anyone else confirm this???
thanks

I don't have audio output from headphone jack but ok using usb headphone
Hi, I was wondering what your licensing policies are for your images, I am interested in embedding one of your images onto my website in the future. Is there an embed option? If not, how much would I have to pay per image?
anybody know about s/n CO7JFACFDWM, its 4gb ram
Hi anyone know how to take the VGC out as mine has stopped working and want to try a possible fix. Thanks! (Mac mini 2012)
Hi, i just came over this teardown, great job! does anyone know what this port is used for? https://d3nevzfk7ii3be.cloudfront.net/ig... you see it in the middle, there is a little connector, im just wondering for what this port is.
The second HD has separate connector?
Will it support NVMe SSD? I mean I see now in Catalina for NVMExpress section: “This computer doesn't contain any NVMExpress devices. If you installed NVMExpress devices, make sure they are connected properly and power on.” Am I correct that instead of SATA SSD I may install there NVMe SSD?
Thanks in advance!
I miss the Temperature sensors in this setup … any hint where I could find more information on those ?
My mini is running hot. Hot enough to shut down instead of spinning up the fan. SMCFan Controls helps as a workaround.
Hi There I was wondering if I could pick someone's brains on something. I just bought a really cheap Mac Mini late 2012. All is working which is quite a finding. I decided to open the little beast to change its HD from a spinning one to an SSD and I found some mangled pieces inside. This little Mac has probably had a really bad drop in the past and it was seriously messed about. Still, all vital parts seem intact, and the machine is working. However, When I was changing the HD I noticed a loose wire.... Looking at pics on this site, I think that the loose wire belongs to the IR connector which is - I think, broken. Since I plan not to use the IR sensor, it will not affect the workflow in any way. The thing is, if I post a pic, can anyone confirm that the loose wire is IN FACT from a broken IR connector? Many many thanks for your help
In step 12, what is the unused connector in the middle of the board?
10 years later and we still don’t have the mini mini.
