What you can do for a Mac not reading an SD card
There are a few ways to fix a Mac not recognizing your SD card. Try these steps if your card reader needs help.
1. Ensure proper connection and orientation of the SD card
Make sure the SD card is inserted correctly into your Mac card reader slot. The card should click into place.
2. Restart your Mac
A quick restart can resolve minor software glitches that may be preventing the SD card from being recognized. Save your work if you can and follow these steps to restart your Mac:
- Click the Apple menu icon > Restart.
- If your Mac doesn’t restart, press and hold the Power button on your computer for about 10 seconds or until it turns off. Then turn your Mac back on.
3. Try different SD cards
Your SD card could be a dud. Test your card reader with another SD card to determine if the issue is with the card itself or your Mac computer’s card reader.
4. Test the SD card reader's functionality
Use a different card reader to see if the issue is with the reader rather than the SD card. If you have a USB-C to SD card reader on hand, try swapping the card readers.
When using a USB-C to SD card reader adapter, you’ll want to try your adapter in another USB-C port to rule out port damage being the reason your computer isn’t reading your SD card.
5. Check Finder settings
If your SD card is detected but not showing up, it may be hidden in Finder.
- Open Finder.
- Click Finder in the top menu, then Settings (or Preferences).
- Click the Sidebar tab.
- Make sure External disks is checked.
6. Use Disk Utility
You can quickly open Disk Utility using Spotlight by pressing Command (⌘) + Space and typing “Disk Utility.”
If your SD card appears in Disk Utility but not Finder, the issue is usually related to mounting or visibility settings.
7. Check accessory connection settings
On newer Mac devices, security settings can block external storage devices from connecting.
- Open System Settings.
- Click Privacy & Security.
- Scroll to Allow accessories to connect.
- Set it to Automatically when unlocked or Always.
8. Reset the NVRAM/PRAM
Resetting the Non-Volatile Random-Access Memory (NVRAM) or Parameter RAM (PRAM) can sometimes resolve hardware recognition issues on your Mac. This step won’t erase your data—though it’s never a bad idea to back up before starting a reset.
On Apple silicon Macs (M1 and newer): You don’t need to manually reset NVRAM. Just restart your Mac—these settings reset automatically when needed.
On Intel-based Macs:
- Power your Mac off.
- Press the Power button, then immediately press and hold the Option, Command, P, and R keys together.
- Hold the keys for about 20 seconds, then release.
9. Data recovery service
If your SD card contains essential data that you can’t access, consider contacting a professional data recovery service for help.
If you've tried these steps and still need a little help, we're right around the corner. Schedule a repair at the nearest uBreakiFix® by Asurion store and our certified experts can get your device back up and running as soon as the same day.
