Hi everyone; thought I'd offer a tip.

Mac Mini Sd Slot Not Working Money


Sometimes my Mac Mini (2010 unibody server model) will recognize an SD card... but then after it's ejected, it won't recognize a new one inserted -- sometimes not even the same SD card. The Mac Mini just refuses to mount a SD card after the original card is pulled out/ejected.

I have a Late 2012 Mac Mini with 16GB OWC RAM running Sierra without problems since I upgraded the RAM. Right after I installed Mojave, however, the lower RAM slot stopped working: two chimes at intervals. Both 8GB RAM modules work fine in the upper slot (no RAM in lower slot). Any suggestions? The 2012 Mac mini has a SDXC card slot. Most of the newer SD cards are SDHC. My 2011 MBP with a SDXC card slot could not read my new 32 Gb SDHC card. I had to get an external USB Card reader that could read the SDHC card as well as the older formats.


This tip from 2011 for iMacs appears to work quite well to fix this issue... at least one my Mac Mini.

'Turns out this is not a software problem, but a hardware problem. There is a small switch inside the card reader that signals to the computer that a card has been inserted. This switch can get stuck.'


'The solution is to insert a toothpick or other non-conductive “stick” into the SD card slot to free up the switch. According to posts on the Apple site, the switch is located at the top/back of the card slot. I also poked around the bottom/back of the slot for safe measure (I never actually saw the switch). After “flossing the inside of the slot a couple times, the reader works once again!'

Remember! Don't use any metal or other conductive materials! Do use plastic or, if you're confident you won't leave splinters behind, a wodden toothpick!


Odd error for the Mac Mini SD Card slot, and odd fix, eh?
