On early 2011 MacBook Pro 15inch -- I use the SD card slot a lot. Suddenly after the upgrade to 10.9.2 (for security reasons), now inserting an SD card gets no reaction, instead of showing an icon on the desktop for the new mounted volume.

  • Have you already checked the Finder's Preference settings (Cmd-comma)?

  • Yes, Finder Preferences is set to show everything.

try another brand of sd card, I had this problem with sandisk cards but al others would work perfectly. You can also try wiggling it around a bit after a while it would read my cards if I did that. Just don't break the card ;)

  • I have currently handy only Transcend and SanDisk cards. I've tried both and the result is the same: not recognized. And this started only when I upgraded to 10.9.2 recently.

  • Eureka. That did it. Must have gotten dirt on the contacts -- now they're clean and the problem is gone. Weird of course that this happened simultaneously with the MacOS upgrade, but clearly that was a coincidence. Thanks, Dennis!!
