The new Mac mini (Late 2014) has no upgradable Memory. Its 4, 8, or 16 GBs of 1600MHz LPDDR3 are soldered to the logic board. A suction cup is required to remove the Bottom Cover. Six T6 security screws are required to remove the Antenna Plate. Each security screw must be replaced before the Mac mini can be reassembled.
Locking customers out of their computers is not a first for Apple. It all started in 1984 with the release of the Macintosh 128k, which had no slots and was bolted together. It makes sense when a computer contains no user serviceable parts. The only upgradable part in a Mac mini (Late 2014) is its Hard Drive. An Apple Certified Macintosh Technician must remove the Power Supply and Logic board to replace the Hard Drive.1
I know this because I am a Apple Certified Macintosh Technician. I have access to the Apple Service Manuals. I do most of the Macintosh repairs at MIT. And I am the one who told Brian Stucki, the founder of Macminicolo, the RAM in the new Mac mini (Late 2014) is not upgradable.
If you are thinking of buying an Apple computer, choose your hardware wisely. You won’t be able to upgrade at a later date.2 All of your computer’s repairs will be performed by an Apple Certified Macintosh Technician. Your computer will be either be glued shut, or screwed up tight. None of the hardware will be user serviceable anyway.
If this bothers you, build a Hackintosh, buy a Dell, or complain to someone else. You are not Apple’s customer. But you are missing out on a great computer.
