Check the connections
If you can’t find the SD card at any location on your Mac, you need to consider the connection problems first. Once you fail to connect the SD card to your Mac correctly, the system won’t detect it, let alone show it up on the Mac.
Therefore, you can follow these steps to check and fix the connection issues.
- Check if you insert the SD card into your Mac correctly
Ensure you insert a compatible SD card with a proper way into the Mac’s built-in SD card slot or the SD card reader. The SD card should be inserted in with the metal contacts face down and face to the slot. For the built-in SD card slot, the thickness of the SD card should be less than 2.1mm. For the SD card reader, make sure the SD card reader is connected to your Mac tightly and correctly.
If you insert the SD card to the Mac’s built-in SD card slot or the SD card reader well but it still doesn’t show up on Mac, check if the slot on the Mac or SD card reader is damaged.
- Check if the SD card is set to not show up on the desktop or Finder
By default, when the external storage device is connected to your Mac, it will appear on the desktop or in Finder (under the Locations section). If you’ve set not to show the external disks on the desktop and Finder, you can’t see them on your Mac.
You can open Finder and move to the top Finder menu bar. Click Finder > Preferences. Then, under the General tab, check the box beside External disks under the Show these items on the desktop section. Besides, click on the Locations section to expand the devices, including the SD card, to show them up in Finder.

Maybe, you’ve mistakenly moved the slider on the SD card to lock it. Therefore, it won’t show up on Mac. You can unplug the SD card and adjust the lock slider to unlock it.

You can select the SD card from the left sidebar of the Disk Utility window and then click the Mount button at the top. After that, the SD card will display on the desktop. You can copy, edit, and delete the photos and other files on it.
