How to fix the SD card not showing up in Disk Utility?
Disk Utility, a built-in system utility designed by Apple, is used for performing disk and disk volume-related tasks on the macOS operating system. By default, it will list all disks and volumes at the left sidebar in the Disk Utility window. However, sometimes the hard drives become invisible on your computer. It’s possible that the setting is modified somehow. To make your SD card visible in Disk Utility, here’s what you can do:
- Launch Disk Utility.
- Click View at the top menu bar.
- Choose Show All Devices.

If the SD card doesn’t show up in Disk Utility, still, you can try to restart your Mac, does your SD card finally make its appearance? If not, it’s not your day. But don’t worry, you have one more thing to do, that is to connect your SD card to a Windows PC. Then you can check if Windows disk management can recognize it. If the PC doesn’t show your memory card as well, unfortunately, either your SD card or the card reader may be physically damaged.
- If the card reader is damaged
This situation is easy to check and handle. All you need to do is change another card reader to test if the memory card can be listed on your Mac. Likewise, you can use other media devices like a camera and access the SD card via a USB port.
- If the SD card is physically damaged
Under this circumstance, you have no way but to send it to a local data recovery specialist for help, especially when you have important data on it. You can also simply buy a new one as a replacement if you don’t care about the previous data.
How to fix the SD card in Disk Utility but not mounting?
One strange scenario is that you can find your SD card in Disk Utility, but it’s grayed out. It means it’s not mounting and that’s why you can’t normally use it on the Mac. An unmounted SD card can result from both computer setting and card corruption. Here are some methods to fix an unmounted SD card:
Method 1: Mount the SD card manually
Right-click on the SD card and choose the Mount icon beside it, or you can click on the Mount button on the top of the Disk Utility window. Either way should be helpful.
Method 2: Repair the SD card with First Aid
If the SD card is showing up but you can’t mount the SD card manually, then the SD card is corrupted for some reason. You should check and repair the disk with Apple’s built-in disk repair tool, First Aid. It can repair disk-related issues on Macs, which include SD cards failing to show up on your Mac.
To use First Aid:
Step 1: Go to Launchpad> Others> Disk Utility, launch it.

Step 3: Select the drive or volume that you want to repair in the left sidebar, here it should be your SD card.
Step 4: Click First Aid on the top menu of Disk Utility.
Step 5: Click Run to check and repair errors in this drive. Wait for the process.
Method 3: Format your SD card
Likely, the SD card is too seriously damaged to be repaired, in this case, it’s time to format your memory card to have a fresh start. However, formatting your SD card is very risky since it will wipe out all your previous data. Therefore, before formatting it, you are strongly suggested to recover your data with professional data recovery software. Then you are good to go.
Step 1: Open Finder, go to the Applications folder and Utility folder, launch Disk Utility.
Step 2: Select the SD card at the left sidebar and click on the Erase button at the top toolbar.
Step 3: Name the SD card and select the file system and scheme for it.
Step 4: Set security options if you want to securely erase all data. Use the slider to choose how many times to write over the erased data, then click OK.
