Created encrypted folder, but it won't let me write to it
I just created an encrypted folder, using the disk utility, and it won't let me write on it.
If I right click on the finder window for the folder, and get info, at the bottom of get info where it has Sharing and Permissions, it says "you can only read", even though in the list of who can do what just below that, it says that I can read and write.
I tried opening a terminal and doing > chmod 700 foldername.dmg
but that didn't change anything.
Any ideas? Thanks much in advance.
