An SD card is a terrific way to store and transfer data while on the go. Files such as images, videos, and documents can be moved between a Mac and an SD card with ease. USB-C Hub with SD Card Reader slot can be used if your Mac has just Type-C connections.
However, a problem with the SD Card not showing up on the Mac may occur for some users. On Mac, SD cards don’t show up. This thread provides a variety of fixes.
1. CHECK IF THE SD CARD IS LOCKED
A little sliding switch on the side of every SD card serves as a security feature, allowing the card to be locked. This will prevent the SD card’s data from being changed or deleted. We recommend unlocking the switch once to see if the data appears on your Mac even when the switch is in the locked position.
2. CHECK THE SD CARD READER PORT
To see if it helps, you can clean the SD card port on your Mac after unlocking the SD card. Try re-connecting your SD card reader to your Mac to see if it helps. To clean the SD card port, use a cotton bud or a small dental floss brush.
3. RESTART YOUR MAC
Restarting your Mac is another simple remedy that we recommend. This will reinstall macOS and all of your software from scratch. To do so, simply adhere to the guidelines below.
For starters, click on the Apple icon.
Step 2: Select Restart from the drop-down menu of choices.
Make sure that your SD card is recognized after your Mac has restarted.
When using the sidebar, make sure you’ve checked your preferences for the “Find” option.
It displays in the Finder’s sidebar and on your desktop when you plug in an external storage device like an SD card. If your Mac doesn’t show your SD card in the Finder sidebar, look for settings there.
Your SD card will be shown in the sidebar by following this guide.
In the top-left corner, select the Finder tab.
To begin, click on Preferences from the drop-down menu.
4. CHECK YOUR FINDER SIDEBAR PREFERENCES
Step 5: Verify that Location has been enabled for all products.
To make your SD card appear on your desktop, follow these instructions.
Step 1: Select Finder from the drop-down menu.
Step 2: Select Preferences from the Finder tab in the upper-left corner.
Verify that everything is checked under the General tab.
If it doesn’t show up, plug in your SD card and check again in Step 4.
5. CHECK FOR SD CARD LISTING IN DISK UTILITY
Disk Utility should list any SD cards that aren’t showing up in Finder or on the desktop. Using your Mac, connect the SD card and follow these instructions.
Open Spotlight Search by pressing Command + Spacebar and typing Disk Utility; then hit Return.
Step 2: In the Disk Utility window, look to the left for an SD card entry.
If the name of your SD card is grey, your Mac has not mounted it. Simply click on the Mount option in the top-right of the screen to correct this..
You should now be able to see your SD card in Finder or on the Desktop.
6. REPAIR SD CARD USING FIRST AID
Even after mounting the SD card, if your Mac still cannot read it, you should use Disk Utility’s First Aid option to fix the problem. First Aid can identify and resolve all SD card storage issues. It’s possible that this method will result in data loss. Since the SD card contains your data, we recommend that you first restore it. These are the steps to running First Aid after that.
Open Disk Utility on your Mac once more.
Step 2: Select the First Aid tab.
Step 3: Confirm your activity by clicking Run.
Check to see if your SD card now appears in Finder or Desktop after completing the First Aid procedure.
7. CHECK FOR SD CARD READER LISTING IN SYSTEM REPORT
The SD card connector on your Mac may not be working properly if the problem persists. Go to System Report in your Mac to see the same. To do so, simply adhere to the guidelines below.
The first step is to select the Apple icon in the upper-left corner by clicking on it.
Step 2: Click on the About This Mac menu.
Select System Report in the third step.
8. RESET NVRAM (FOR INTEL MACS ONLY)
If the details like Vendor ID and Device ID are not visible after selecting the choice in Step 5, go to Step 6. If your Mac does not have a built-in card reader, you will not be able to see this information.
You can try the following if you still can’t see anything after picking the option.
9. RESTART USB DAEMON FROM TERMINAL
To reset the NVRAM on an Intel-powered Mac, follow these instructions: NVRAM (Non-Volatile Random Access Memory) stores data such as the volume of sound, the startup disk, the time zone, and many more things. If your SD card isn’t showing up on your Mac, you can attempt this solution. Once the NVRAM reset has been performed, these settings will need to be changed again on your Mac. To do so, simply adhere to the guidelines below.
The first step is to click the Apple logo and choose Shut Down.
The second step is to restart your Mac.
For the final step, hold down the Option + Command + P + R keys for a total of 20 seconds as your Mac boots up.
When the Apple logo shows for the second time, the NVRAM reset is complete and all four keys can be released. Afterwards, your computer will reboot.
Step 5: Re-insert your SD card to make sure it’s recognized this time.
9. RESTART USB DAEMON FROM TERMINAL
USB Daemon is a procedure that takes place in the background of your Mac and manages external storage devices, as well as data transfers. Otherwise, your Mac will not be able to read or recognize your SD card or any other external storage device. The Terminal application on your Mac can be used to restart USB Daemon. To do so, simply adhere to the guidelines below.
In order to open Spotlight Search, press Command + Spacebar and type Terminal. Then hit Return.
Step 2: Once you’ve opened Terminal, type the command below:
stop com.apple.usbd with sudo launchctl, then start it with sudo launchctl
Press the Enter key on your keyboard to complete the process.
Step 4: Close Terminal and insert your SD card to verify whether or not your Mac recognizes it when the operation is complete.
10. VISIT YOUR NEAREST APPLE STORE
When all other options have failed, we recommend that you visit an Apple Store. The SD card port could be having some issues right now. We recommend purchasing a new USB-C SD card reader for your Mac if you are currently using one that does not.
Use an SD card for your Mac
You may be able to transfer files from your SD card to your Mac using these solutions. In the absence of a USB-C Hub, a USB-C SD Card Reader can be used to transfer files to and from your Mac.
