How to Remove Write Protection on SD card on Mac? How to Disable It?

This guide helps you resolve the frustrating issue of a write-protected SD card. Whether it's a physical or digital lock, or a virus causing the problem, we'll show you how to regain control of your SD card and access its contents.

Fixing a Write-Protected SD Card

A write-protected SD card prevents saving, deleting, or formatting. Before attempting any software solutions, check for a physical write-protect switch on the side of the card. If present, slide the switch to the "unlock" position.

Removing Digital Write Protection on a Mac

If there's no physical switch, the write protection is likely digital. This can often be resolved using Disk Utility's First Aid feature:

1. Insert the SD card: Make sure your SD card is securely inserted into your Mac.
2. Check file permissions: Open a file on the SD card and select "Get Info." If it's read-only, you'll see a message indicating this.
3. Open Disk Utility: Use Spotlight search (CMD spacebar) to find and open "Disk Utility."
4. Select the SD card: Choose your SD card from the list in the sidebar.
5. Run First Aid: Click "First Aid" and then "Run." Allow the process to complete. This repairs disk errors, often resolving the write protection.

Virus Removal

A virus can also cause write protection. Run a thorough scan of your SD card using reputable antivirus software (like MacKeeper's Antivirus).

After scanning, check the file permissions again. The read-only restriction should be gone if a virus was the cause.

Additional Troubleshooting

• NTFS Driver: If your Mac can only read files from a Windows-formatted SD card, an NTFS driver (like Paragon Drive) might be necessary.
• Formatting: As a last resort, format the SD card. Remember to back up your data first! You can do this within Disk Utility's First Aid.

Safe SD Card Usage

Regularly check your SD card for issues. Keep your antivirus software enabled (like MacKeeper's Antivirus) for ongoing protection.
