How should I restore a backup of my user account from a .dmg?
Copy the user folder into /Users
Make a user with the same short name as the user that you copied in using the Users &amp; Groups preference pane. This should prompt you to link the new user to the home folder that you copied in.

Note: Don't log in as that user yet.
Reset the new user's ACLs using the ACL tool on the Recovery HD.


Boot into the Recovery HD using ⌘R.
Run resetpassword in Terminal (available from Utilities → Terminal).
Select your account from the drop-down list.
Click the Reset button for Reset Home Directory Permissions and ACLs.
