Why isn't my SD card showing up on my Mac?

Normally, when you connecting an SD card to your Mac directly or via an external card reader, it should appear in Finder, on the desktop and in Disk Utility. However, in most of the cases, you don't see your SD card show up on Mac because you haven't setup your Mac to.

What's more, there could actually be a number of other reasons for the SD card not showing up. A few possible candidates include:

  1. Virus infection
  2. System error
  3. SD card corruption
  4. Damage to the Mac card reader slot

In either case above, you can try out the following solutions one-by-one and your SD card should wind up safe and sound, along with all of the precious data that you have stored on it.

The worst scenario is, if you cannot see the SD card showing up in Disk Utility, it unfortunately indicates that your SD card isn't recognized. It could have sustained physical damage that is beyond our fixes here.

Thus, examine it carefully to see if you can see any noticeable damage to it. It could simply be overly dusty or greasy, so perhaps give it a quick wipe down with a clean, dry cloth and try again. If not, the card may be repaired by a professional company, although if there wasn't any very important data stored on there, you may simply wish to purchase a replacement.

How to fix the SD card not showing up on Mac issue?

If your Mac is set up to show up SD cards in Finder and on the desktop but you still cannot see it, there may be something wrong with your SD card. Probably, the file system of the SD card is corrupted. If that is the case, you could see the SD card detected or showing up in Disk Utility, but it is unmounted or greyed out.

Now, you can try the methods as below to mount the SD card or fix the corrupted SD card.

Solution 1: Mount the SD card manually

You can try to mount this SD card by clicking on the Mount icon beside it, or by clicking on the Mount button on the top of Disk Utility window. Either way, you may mount it and then access pictures, videos or other files stored on it.

Solution 2: Repair the corrupted SD card with First Aid

If you can't mount the SD card manually, then another very effective strategy that you could implement when it comes to the SD card not showing up on your Mac computer is to repair it with First Aid in Disk Utility. Disk Utility is there to repair specific disk-related issues with Macs. This does indeed include SD cards failing to show up on your Mac. To use the Disk Utility feature:

Step 1: Go to Applications > Utilities > Disk Utility.

Step 2: Select the SD card that happens to be unmountable and, at the top, click "First Aid".

Now, sit back and wait for the repair process to finish and hopefully work its magic.

Solution 3: Reformat your SD card

If you have still not had any luck in getting your Mac to read the SD card, it could be time for you to reformat. This is perhaps the most complex solution so far, but it gives unmountable (unreadable) SD cards the chance to rebuild and restructure the disk structures, while avoiding utilizing any bad sectors. If your SD card is not showing up on a Mac computer, it is a very sound strategy. Now, before we go any further, we need to talk to you about the data stored on your SD card. If there is any data stored on your SD card that you are desperate to keep, reformatting is not for you. Reformatting will erase all of the data stored on the card and will essentially wipe it clean. If you happened to perform a regular Time Machine backup beforehand, you should be able to recover data from Time Machine.
