Introduction

Noisy or poorly-performing fan? Use this guide to replace the fan, or remove it for cleaning in your Mac Mini Late 2014.

Read Me First: I purchased an SSD drive directly from Crucial and, of course, it came uninitialized. After going thru the entire tear down, installing the new drive, and rebuilding the mini, it refused to recognize the new drive. So, of course, I had to re-tear it down, remove the new drive, insert it into an external housing and format it using my Macbook. After that the mini recognized the new drive. A word to the wise: format the new drive before installing it.

How were you installing the OS? I am planning on booting into a USB drive with a copy of OS High Sierra on it, and I assume I will be able to format my new Samsung SSD using that?

Pre-formatting is not necessary if you make a USB boot installation drive with macOS installer. During boot up, hold down the option key until the mac boot into the USB, formatting can then be done using disk utility running off the USB drive.

I used some wooden toothpicks instead of the opening tool. This worked flawless for me.

I taped the "Mac Mini Logic Board Removal Tool" to the flat part of the antenna plate before sealing everything up again. I mean, where else am I supposed to store it without forgetting where it is? I'm pretty sure it won't cause any problems there.

Had a T7 security screw driver [and didn't want to wait to have the T6 version shipped to me], so I gave it a whirl. I lined up the driver with the screw socket, pressed down a bit to make sure the driver would get enough grip, and slowly [but forcefully] rotated the driver and got these screws out. BE CAUTIOUS not to strip the screws. May not work for everyone.

As TR6 screwdrivers were sold out all over Germany and I wanted to exchange the HDD THIS friday, I took a VERY fine dental milling tip (0,8 mm head diameter) for my proxxon and milled away the little dots in the center of the the TR6 screws. After that I could open the case with a regular T6 screwdriver. All went fine, MM is closed again + working like a charm with it's new SSD. NOTE: For this task I used my loupe glasses (3x) ;)

On the whole screw thing. I just used a tiny dremel drill bit and drilled out the security pin. I hate those screws. I don't see the point in locking the them with those. they should have left the screws alone.

That worked for me, thanks for the trick!

I used the T7 very carefully. No problems.

I just had success using standard pliers to remove the longer screw posts, and then I used standard needle nose pliers to press down and grip the tiny screws. Please note that this method may/will cause scrapping of the aluminium cover.

Northern Tools sells a set of 13 Torx Security Keys for $28.99 that has the TR6 size.

On my 2nd drive replacement (swapping out to an SSD this time). Could not find my logic board removal tool. So I made another one from a metal coat hanger. So, here’s my tip, when you put it all back together: the logic board removal tool fits around that small black circle antenna perfectly and you can replace the large black cover over the top snuggly. No rattles or anything.. So, next time: I’m guaranteed to find my logic board removal tool.

Do not completely remove the antenna plate; it is still connected to the Mac Mini by an antenna cable. With the I/O ports facing you, flip the antenna plate to the right to allow access to the antenna cable connector.

Is this really necessary? The antenna is no where near the SSD drive....

This was the most tricky part for me when remounting the Mac Mini. With my bad eyes, I’ve spent 10 minutes inserting this tiny round antenna plug in the hole. I’ve decided to put the screw back without tighten it too strongly and then it was easier.

I have been having wifi issues ever since I changed the drive. I don’t know if this connector is the cause or not.

Had a problem with a noisy fan. Apparently the blades were scratching its housing, so i just bend the aluminium housing a bit and spin the fan to see if its still had a contact. It works like a charm.
