Another common cause for the external hard drive 'Read Only' problem on Mac is the formatting errors of the storage device itself. If you see a warning says the device is only being mounted in read-only mode while connecting, your hard disk is diagnosed to have formatting errors that prevent you from writing files to it.

Step 4: Click Erase to reformatting your external hard drive.
