The data and documents on your SD card display as read-only when you connect it to your Mac computer, and you can only access them to read or see them. So, what gives? Is there a way to get rid of this issue, please?
Stop worrying! Sometimes you may experience issues with your SD card, such as being read-only, not appearing on your device, or becoming corrupted. If an SD card is set to read-only mode, you won't be able to make any changes to the information already on it. Fortunately, the solution to this problem is straightforward. If you read this piece, you'll understand.
What does Micro SD Write Protection mean?
SD Card Write Protected is another name for "read-only" errors on an SD card. Despite its name, this feature only reads and cannot change it. That happens on Android every once in a while. There will be rapid shifts to read-only periods. Because of this, you can no longer update or remove data from the SD card.
Use the Micro SD card's write protection function to prevent data from being overwritten or erased. When a Micro SD card is write-protected, you can still access the files on the card, but you won't be able to copy or move them to another device.
The following are the most common reasons for the "SD Card Read Only" error:
- Occasionally, we'll turn on write protection and secure the SD card.
- The SD card's physical write protection switch.
- As a result of the application, the SD card displays the message "SD card read-only."
- The SD card could have corrupted files.
Solution 1: Unlock the physical write protection tab
There is a physical write protection tab on some SD memory cards and adapters. The SD card cannot be written on a Windows or Mac machine while the switch is in the Lock position. You need to turn off write protection to access the SD card.
Remove the SD card from the adapter or the computer if it is a read-only card.
Look for a physical write-protection tab and see if it's present. That is possibly the appearance of the safety lock button.
To remove the write protection, move the tab from the Lock to Unlock position. Then, see if you can test writing to it right now.
Do not fret if it does not work. If one option fails, try another.

Solution 3. Solve read-only issue with NTFS for Mac tool
In some cases, you may find the SD card is read-only because that it is an NTFS device. NTFS file system is a Windows-based file system and is not compatible with macOS. If the SD card has been formatted to NTFS, it won’t be read-write on a Mac. To solve this issue, you can try a NTFS for Mac tool - such as DoYourData NTFS for Mac software.
Step 1. Download and install DoYourData NTFS for Mac, run it from Mac Launchpad. Make sure the SD card has been connected to your Mac.
Step 2. Under NTFS Disk, find the SD card, then click Enable Writable. It will grant full read-write access to all NTFS devices on your Mac.
After enabling writable, you can write data to the SD card without any limitation and you can find the SD card becomes read-write.
