Can't delete files from an encrypted dmg container
MacBook Pro, OSX 10.11.3
I created an encrypted dmg container, using Disk Utility. I chose the Read/Write option. When I open the DMG file using the password I can view the files it contains, however, when I try to delete files from it I get an error message:
"The item “IMG_6617_1.mp4” can’t be moved to the Trash because it can’t be deleted"
Is there a way to be able to add and remove files from the DMG file?
Thanks,
Jeff
