I have an encrypted, password-protected sparsebundle that I occasionally mount and unmount from the terminal. I want the system to ask for the password every time I mount it, but for some reason it keeps remembering.
This is how I mount it:
hdiutil attach ~/path/to/my/bundle -mountpoint ~/my/mountpoint
These are some of the ways I've tried to unmount it:
hdiutil detach -force ~/path/to/my/bundle hdiutil detach -force /Users/me/path/to/my/bundle hdiutil eject -force ~/path/to/my/bundle diskutil eject ~/path/to/my/bundle diskutil unmount force ~/path/to/my/bundle
(I've read here that
hdiutil unmount is not sufficient to make the system forget the password.)
However, whatever I try, the system "helpfully" remembers the password each time.
Only when I use the eject button in Finder, does the system forget the password.
Also, there is no entry in my keychain that suggest the password has been cached. (At least, I can't find it. There are none with kind
disk image password.)
I've even created a new sparsebundle, with a new name and a different password, but the problem persists.
What am I missing here? How can I make sure the sytem always asks for the password, each time I mount the sparsebundle?
