Hi, for the first time, I inserted an SD card into my MBP SDXC slot and it's not reading or showing up in Finder? Should it be able to read SD cards? Is the slot dead?
 
It should read just about all sd cards. With that being said, I have an early 2011 13" that reads my Kingston, Kodak, and Patriot but not my Sandisk.
Thanks, it's a Kingston card. I wonder if the reader is dead? I ended up putting the card in a USB reader and I copied it over, so I know the card is good. Bugging me on whether the slot reader is dead.
 
It could be that the reader is picky about the sd cards.

I have one card that is seen in disk utility when I boot from an installation usb key but not when I open disk utility from Sierra.
 
Thanks. I'll try another card when I come across the need again. This was my only card and it’s pulled from an old digital camera.

Sounds familiar. If you’ve never used it before, there’s a high likelihood you’ve got dirt stuck in your slot . Try blowing into it forcefully a few times, use compressed air or an alcohol-based cleaning solution that will evaporate without leaving any residue to clean the electrical contacts within.

Bingo, that was it. Blew hard into the slot and then sprayed some alcohol onto an microSD to SD Adapter (not the actual SD I was looking to read) and inserted and removed a few times, repeated with alcohol and all is good. It reads my camera SD.

Thank you.

OP:

I've found that the SD card slot in Macs can be "picky" about what cards it reads, and others that it chooses not to read. You never know.

Surefire, 100% "read 'em every time" solution:
Spend $15 and buy a USB3 card reader.
That's what I did.

Yes, I have one and used it. Just bugging me whether it was dead or not.
