Full Summary
In the early 2000s, Apple introduced iChat AV, a pioneering tool for audio and video conferencing, alongside the iSight webcam. This was during a time when competitors like Microsoft and AOL dominated the consumer video conferencing space.
Recently, it has been discovered that iChat can still function on older Macs running Leopard or Snow Leopard, provided the router supports port-preserving NAT, which most do. For users with BSD-based routers like pfSense or OPNsense, enabling source port preservation in outbound NAT settings is necessary for iChat to work.
This revival allows users to reconnect with a nostalgic yet functional conferencing tool, highlighting the longevity of certain software despite advancements in technology.
