How did you restore them?
Our Time Machine eggs spurt Pondini.. is really great at this stuff..
See the whole section Q14-17 here. http://pondini.org/TM/FAQ.html
And permissions as a particular issue here.
Permissions should not be an issue if you migrated the backup, as per the instructions.
But I have run across it, and ended up doing a double restore.. first time to external drive then fixed permissions as copied them to the actual Mac.
