How do you remove write protection on an external drive in MAC OS X?
To remove write protection on an external drive in macOS, first ensure the drive is not physically locked (some drives have a switch for this). Then, open "Disk Utility" from Applications > Utilities, select the external drive, and click on "Erase" to format the drive, which can remove write protection. If that doesn’t work, check the drive's permissions by right-clicking the drive icon, selecting "Get Info," and adjusting the "Sharing & Permissions" settings to allow read and write access.
