I just connected a new 27" Thunderbolt Display monitor to my 15" MacBook Pro, but when I go to Displays as instructed to set up the configuration of the monitor (mirroring or extended desktop) there is no "Arrangement" tab as the instructions indicate. Is there a work around or am I missing something here? Using OS X (10.6.8) if it matters...
Any advise is much appreciated
