2. Restart Won’t Work? Check These Devices Carefully

When we read and write on a SD Card, there are 3 items required to complete this job: a Mac, an SD Card Reader and the SD Card itself. So, no matter what the ultimate reason is to lead to SD Card Not Showing up on Mac, it must be relating to any of these devices. Consequently, we need to check these devices carefully before using 3rd party tools.

First, check the Mac

Cause: Ineffective Mac USB Port

Test: Connect the SD card reader to your computer via different USB ports if your Mac doesn’t come with a card slot.

Solution: If the previously USB port is ineffective, change to another USB port, or connect your sd card reader to anther computer.

Then, check the SD card reader 

You may need a card reader to access to the SD card data on your Mac. And as time goes by, there will be dirt and dust accumulated in your SD card reader, which will adversely impact the contact between your SD card, SD card reader and the computer. In this case, lightly wipe your SD card reader with a cotton cloth soaking a little alcohol. Then try again to connect the SD Card to your Mac with the card reader and check if it works.

Finally, check the SD card itself

Cause 1: Poor contact of SD Card.

Solution: Same as that for SD Card reader, try to blow away the dirt or dust clogged deep in the slot of your SD card, or lightly wipe. 

Cause 2: The SD Card is locked

Solution: In this case, we need to first make sure that your SD card’s lock switch is in the “Unlock” position, otherwise, there will be meaningless to remove the write protections.

    My iMac does not recognize my SD cards when using the card slot in the computer but does recognize them when I use a card reader plugged into a USB slot. Any ideas? Thanks.

      Was the card seated in the slot properly? It might be the compatibility issue.
