In general, after you connect an SD card to a Mac, the SD card will show up on the desktop, in the Finder or in the Disk Utility. If you can find the SD card in Disk Utility but not on the desktop or in the Finder, you should feel relieved because the problem is fixable. However, if you don’t even see the SD card in the Disk Utility, it is most likely that the SD card cannot even be detected because of the physical damages. The reasons why the SD card is not showing up in the Finder include the incorrect Finder setting and the mounting issue for the SD card. Let’s make your SD card show up in the Finder again.
Change Finder setting
After Mac detects and mounts a disk, it will be shown up in the sidebar of the Finder for users to access the SD card easily. However, if the default setting is somehow changed, your SD card won’t appear there. It is easy to correct the setting: Then your SD card will show up in the Finder now. If the card is not showing up in the Finder after you change the setting or the setting was correct, it could be the SD card not mounting successfully. You can first mount the SD card manually in Disk Utility to see if it can be mounted. If not, your SD card must be corrupted and needs repairing or formatting. To make the SD card show up on Mac normally, follow the methods below:
Repair the SD card with First Aid
