I remember reading early reports that programs such as InsomniaX and Caffeine did not work on the new 2011 MBP's - does anyone know if a workaround had been found or if someone has figured out a way to prevent these machines from sleeping? I hate leaving my MacBook open, but I use Plex to watch all my Mac's videos from the iPad, so I can't really close it down at night without it sleeping and killing Plex.
