A technician has turned off Bonjour on a Mac and now Logic 9 gives the erroneous message upon bootup that there is a license error, as if another Logic with the same serial number is booted up elsewhere on the network. But the Mac isn't even plugged into Ethernet, and there is no Airport card, and Bluetooth is turned off (and there is definitely no Mac or network connected in any conceivable way, Firewire or otherwise). I have no clue what Bonjour is (other than it is required to be turned off for their Internet to work). I have no clue how to turn it back on (a search in the Mac help or Finder yields no results). I don't know if the two are related either, but the exact same problem happened on a completely different Mac in an identical situation (but with Logic 8), Bonjour turned off but nobody knowing how to turn it back on. Bring back the dongle!!!!! I've had far more trouble without it in many contexts.
