To help you fix the SD card not showing up, working, or reading on Mac, here is the list of all solutions.
Fix 1. Check the Connection
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.
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 Test it Using Another Device
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 it on another device, 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 Your SD Card Reader
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 (or More Info > System Report 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 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.

Fix 4. Check Finder Settings
It's good news if your SD card shows up there. This indicates that the card is physically functioning and that incorrect Mac settings may be preventing it from appearing where you expect.
By default, external drives can be configured to appear on the desktop and in Finder. Let's walk through how to adjust these settings so your SD card shows up on your Mac's desktop and in Finder.
Here's how to show the SD card on the Mac desktop and Finder on macOS:
- Open Finder.
- From the menu bar, click Finder > Settings.
- In the General tab, tick the box next to "External disks" to show the item on the desktop.
- In the Sidebar tab, tick the box next to "External disks" to show them in the Finder sidebar.
Fix 5. Check System Information
Providing the SD card doesn't appear in Disk Utility, open System Report (it will list out the System Information) > Hardware > USB and check whether the Mac detected the connected SD card.
If the device appears under USB but not as a usable disk in Disk Utility, your Mac can detect the USB connection but may be unable to properly access the storage device or recognize its file system.
Note: "Seeing the card reader" does not mean that the SD card's storage medium has been successfully initialized. Make sure your SD card is initialized first.
Fix 6. Update macOS and Check Accessory Compatibility
Sometimes, upgrading to the latest macOS version can fix your SD card not working issue. To update macOS to the latest Golden Gate 27, go to System Settings > General > Software Update, then install the available update.
Then, restart your Mac, reconnect the SD card using a card reader, and try reading from and writing to the card again.
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.
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.
Fix 7. Reset NVRAM/PRAM
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 8. Manually Mount the SD card
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.
Just open Finder > Applications > Utilities > Disk Utility. Then select the SD card and click the Mount option from the toolbar.
Fix 9. Recover Data from the SD Card
If your SD card won't mount, or it's risky to repair your SD card, it's recommended to recover your important data first. You can use iBoysoft Data Recovery for Mac to recover photos from a detected camera memory card.
iBoysoft Data Recovery for Mac supports recovering photos, as well as videos, music, documents, Email, archives, etc., from unmounted, corrupted, unreadable, or inaccessible internal and external storage drives, like SD cards, memory cards, HDDs, SSDs, and USB drives.
Note: This software works with SD cards that macOS can at least detect. If the card does not appear in Disk Utility or System Information, the software usually cannot scan it. In that case, you should first troubleshoot the connection, card reader, or hardware issues.
Watch this video to learn how to recover accidentally deleted or lost data from the detected SD card quickly.
Alternatively, you can follow this step-by-step tutorial to perform SD card data recovery on Mac.
1. Download and install iBoysoft Data Recovery for Mac on your Mac.

Fix 10. Repair SD Card via First Aid
To use First Aid to repair a corrupted SD card, keep the following notes in mind before you take any further action:
- Make sure your important data is backed up, or recover any critical data before proceeding.
- Check the SD card one volume or device level at a time.
- If First Aid fails to repair the card, don't keep running it repeatedly. Instead, move on to data recovery or seek professional assistance.
Now, repair your SD card via First Aid in Disk Utility:
- Go to Finder > Applications > Utilities > Disk Utility.
- Select the corrupted SD card and click First Aid on the top.
- Wait until the process is finished and click Done.
If your SD card cannot be repaired with the First Aid tool, for example, you receive an error message like this: Disk Utility can't repair this disk, formatting the SD card will probably eliminate any errors that stop your Mac from reading it.

Fix 11. Format the SD Card Only After the Data is Safe
Formatting the SD card will restore the SD card to a blank state, meaning all stored files will be deleted. Formatting rebuilds the file system; it does not repair a physically damaged SD card. To avoid permanent data loss, use iBoysoft Data Recovery for Mac to retrieve as many files as possible. If you haven't secured your files, do it now.
Then find the details on how to format an SD card on Mac.
- Select the SD card from the left sidebar of Disk Utility.
- Click Erase on the top.
- Set a name for your SD card, and select a file system and the Scheme.
- Click Erase and wait for the SD card to be formatted.
If your SD card not showing up in Disk Utility at all after trying all the above methods, it means the SD card has some hardware problem so the Mac can't detect it. In this situation, you have no choice but to send the SD card to an expert for reparation and/or retrieve data.
