Check here how to insert an SD card into your Mac:
If your Mac comes with a built-in SD card slot, you can insert a compatible SD card. And note that:
- Avoid using an SD card that has a thickness greater than 2.1mm.
- Make sure that the metal contacts face down and point toward the computer when inserting an SD card.
- If your SD Card is an SD adapter for microSD, make sure the MicroSD is inserted properly in the adapter, if the issue persists replace the adapter for another one.
- Do not force the device into the slot if you note an uncommon resistance, instead pull back the SD card or MicroSD adaptor and visually check for deformities in the card or slot.
Anyway, a simple reboot can fix a computer issue 80-90% of the time. It also works when external drives are not showing up on Mac. So, when your Mac like MacBook not reading the SD card, you can try to remove the SD card and then switch off the Mac. Leave it for a few minutes, turn it back on, and try again.
Then your computer will recognize the SD card inserted into the card slot as a storage device. You can read and write to an SD card just like any other external drive.
But if your MacBook Pro/Air has no SD card slot, you need to buy an SD card reader/adapter for your Mac and download its SD card reader driver. Insert the micro SD card into the slot face up with the gold pins going first.
If your SD card is still not showing up, download (free download), install iBoysoft Data Recovery on your Mac, and then check if your SD card is recognized by iBoysoft Data Recovery.

1. Go to Finder > Preferences > General, and make sure the "External disks" option is ticked. This will make the SD card show up on the Desktop.
2. Select the Sidebar tab on the top, and make sure the External disks option under Locations is also ticked.
3. Go to Desktop and check if your SD card is showing up.
Fix 3: Check if the SD card is locked or damaged
Another case for Mac not reading SD card is that the SD card is write-protected. To work on the SD card again, you need to safely eject the SD card and adjust the lock slider tab on the SD card to unlock it. Then, reinsert the SD card into the slot.
If it is still not working, you can test if your SD card is damaged on different devices, such as phones, digital cameras, or other computers.
For instance, you can remove the SD card from your Mac and insert it into your digital camera. If your SD card is still not detected or working on the camera, the card might be damaged, or you need to try the following solutions.
Fix 4: Check if the SD card reader is not working
Commonly, the latest Mac models have no SD card slot. You usually need an SD card reader for MacBook Pro to read your SD card. When your Mac doesn't recognize the SD card, it is necessary to check whether the card reader is working or not.
It doesn't matter that you access the SD card by the built-in slot on your Mac or a third-party SD card reader (or adapter). Simply follow these steps to check if the SD card reader is recognized or not.
- Click Apple Menu > About This Mac > System Report(the location has been changed on macOS Ventura).
- Find Card Reader under the Hardware list.
- If the card reader works, you can see its Vendor ID and some other product information.
When your SD card is inserted, it should also be listed on the right pane with specifications.
If unfortunately, the SD card reader is not working, it might be an SD card hardware issue. For a broken slot built in your MacBook, you need to send it to a local Apple store for repair service, but you can still work on SD cards with an external reader until you fix the built-in one. Instead, for a malfunctioned external SD card reader, you can simply replace it with a new one.
Fix 5: Mount SD card in Disk Utility
If your Mac can't read and recognize an SD card, you should go to Disk Utility and see whether the SD card is listed. Just Open Finder > Applications > Utilities > Disk Utility.
If your SD card is showing up in Disk Utility, but the SD card is greyed out, that means the SD card is not mounting on Mac. Simply select the Mount option to see if the SD card will be mounted and appear in Finder and the desktop.

It's worth resetting whenever you find your computer's hardware acting in unexpected ways. For example, an SD card can't work on Mac.
To reset NVRAM, you should shut down your Mac, then turn it on and immediately press and hold Option + Command + P + R. Keep holding down those keys for about 20 seconds. Then release the keys and allow your Mac to continue starting normally.
