Fix 1: Check the connections and restart your Mac

When your SD card not showing up on your Mac after being inserted, the first thing you should do is to check the connections.

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 with 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.

How to insert an SD card on Mac

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.

Fix 2: 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.

Unlock a write-protected SD card

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 3: 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.

  1. Click Apple Menu > About This MacSystem Report (or More Info > System Report on macOS Ventura).
  2. Find Card Reader under the Hardware list.
    Find SD card reader info on Mac
  3. 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 into 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.

NVRAM/PRAM, a chip in an Intel-based Mac, is used to remember the basic settings for your computer, including sound volume, display resolution, startup disk selection, peripheral devices, and more. 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.

Fix 7: Update the drivers on Mac

If the problem persists, you can check whether the drivers on your Mac are renewed. If your Mac drivers are outdated, your SD card or other external hard drives will not be recognized by your Mac.

In addition, for those whose SD card can't be read by the M1 Pro or M1 Max Mac after reformatting. Apple says that its future software update will fix this issue.

So, updating your Mac and the drivers is indispensable. You can follow these steps to update drives on Mac:

  • 1. On macOS Ventura, go to Apple Menu > System Settings > General > Software Update. If any updates are available, click Update Now to install them.
  • 2. On macOS Big Sur or macOS Monterey, you should choose Apple menu > System Preferences > Software Update. If any updates are available, click Update Now to install them.
  • 3. On an earlier version of macOS, launch the App Store. Click the Updates tab on the top and check if any items need to be updated, then update them.
