Mac OS X 10.1 works with IrComm, an infrared communication protocol, on the PowerBook G4 (Gigabit Ethernet) computer and some third-party USB infrared pods.
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.
