Unable to create folders in my DMG file on MacBook Pro
I have created a .dmg which I can access after password entry. OK so far. But I cannot create a folder in it even though it is R/W to me. Am I right in assuming I must have everything I need in there as folders and files before I protect the folder? Thanks.
