  • Connect your SD card with Mac properly. Make sure the connection is tight.
  • Open the Finder by clicking the smiley face on the desktop.

Now your SD card should appear in the Finder. Still, chances are you can either find the SD card on the desktop or the Finder. Maybe you can go to Disk Utility to check. If the SD card lies safe and sound in Disk Utility, but you can’t mount it, what can you do?

How to fix the SD card showing up in Disk Utility but not mounting?

The unmounted SD card can also result in an SD card not showing up on Mac. To fix this issue, we offer three solutions for you.

Solution 1: Manually mount the SD card

Automatically, your Mac will mount the SD card. But accidents always happen, and you can manually mount the SD card by right-clicking on it and choosing the Mount icon beside it. Or you can select the memory card in Disk Utility and click Mount on the top of the menu. How’s it going now? If you can’t mount it manually, it means the SD card might be corrupted and needs to be repaired, or even formatted.

Solution 2: Repair the corrupted SD card

You can use the Apple built-in repair tool, First Aid, to fix your corrupted SD card. Follow these steps:

Step 1: Go to Launchpad and then Others. Select Disk Utility.

Step 2: Select the unmountable SD card and click First Aid at the toolbar.

Now you can wait for the magic to be done. If you still have no luck in mounting your SD card, perhaps you can move to the next method.

Solution 3: Format your SD card

You can resort to this method when your SD card is too severely damaged to be repaired. However, formatting will erase all the original data on your SD card and write a new file system on it. Therefore, before making any move to your memory card, always remember to back up the files or restore the important data first! Then you are good to go.

Step 1: Go to Launchpad > Other > Disk Utility, launch it.

Step 2: Select the SD card at the left sidebar and click on the Erase button at the top.

Step 3: Give the SD card a name, file system, and scheme. We recommend exFAT or MS-DOS(FAT) as the file system.

Step 4: Click on the Erase button to format your SD card.

Once it’s done, you’ll get a fresh new well-functioning SD card. Then you can transfer your backups to it.
