macOS Sierra: AppleScript mount volume keeps asking for login
-

Question
For several OS X versions I've used:
/usr/bin/osascript -e mount volume "smb://yourserver" as user name "yourusername" with password “yourpassword”
This has worked great, a nice and quiet mount of the network share, if it is available of course.
Now recently I installed macOS Sierra (10.12 public beta, build 16A238m), and the script still works, however it will now suddenly always show a login dialog, pre-populated with the "yourusername" and "yourpassword" values. The user will still have to click "Connect" to mount the share.
Does anyone know if this is a "bug" in the beta version (I did report this with Apple's Feedback app), or is this expected and/or what would be the "fix" for that?

Solution
As Apple replied to the ticket referenced in mattdwen's Open Radar link above, as of macOS Sierra 10.12,
you can no longer create items in /Volumes unless root.
Further, my best understanding of the AppleScript mount volume command is that it doesn't have a way to specify the mount point and consequently it only mounts volumes under /Volumes
through the Finder's standard mechanism. So, I don't think you can do it via AppleScript.
But there's another way. You can accomplish the same thing using the lower level mount
command:
mkdir -p ~/mnt
mount_smbfs "//my_username:my_password@my_hostname/share" ~/mnt
After mounting the volume this way, you should see a normal "volume" icon appear on your desktop and the ~/mnt
directory will appear as "share" when you browse your user directory via Finder.
The one thing missing from this approach is saving the login credentials in Keychain. To do that, you have to do a bit more scripting. Something like this.
Save the password:
security add-generic-password -a my_username -s my_hostname -w my_password
Retrieve the password and mount the share:
pass=$(security find-generic-password -a my_username -s my_hostname -w)
mount_smbfs "//my_username:${pass}@my_hostname/share" ~/mnt
NOTE: If you have special characters in your password, you will probably need to URL encode it, perhaps like this:
pass='my !@#%%^& password'
pass=$(php -r "echo urlencode(\"$pass\");")
>>> my+%21%40%23%25%25%5E%26+password
OTHER TIPS
This has been fixed by Apple in macOS Sierra 10.12.2:
