saxat från knowledgebase (artikel 106617):
"The following computers have built-in infrared hardware that does not work with Mac OS X 10.1:
*
PowerBook G3 Series
*
PowerBook G3 (Bronze Keyboard)
*
PowerBook (FireWire)
*
PowerBook G4
*
iMac 233 (233 MHz, 233 MHz/B)
These computers may communicate more efficiently via Ethernet cables. Infrared´s vulnerability to interference (from florescent lighting, for example) and limited ability to operate over relatively short distances make it a less ideal choice for communication than AirPort wireless or Ethernet technologies."
Om du ska köra Ir via OS X ska du nog tänka på att första generationens PBG4 inte stöder det (inte fullt i alla fall??). har för mig att det finns nån slags USB kabel man kan koppla mellan telefon och dator som lösning.
