Photos on SD card now "Read only" and locked

Thanks, I got it fixed.

The only bad system seemed to be CleanMyMac. Maybe it conflicted with the new Catalina OS? I'm not that computer savvy.

One of the worst...

CleanMyMac —excellent marketing campaign, strong wallet vac, and is known to cause nothing but added issues on the macOS, it is never recommended.

Thanks, which computer protector would you recommend for a MacBook?

Third party AV is not recommended— it typically does nothing but add issues to the macOS and competes directly with Apples own built in security:

My SD cards from game cameras are now locked and "Read Only." The lock tab is not on lock. I cannot delete the photos on my computer, but can delete them in a camera other than my macbook pro

Reformat the SD card using the camera if you have an issue.

If the SD card is failing in some way

Try a different SC card to compare results.
