Do you remember when it JUST FUCKING WORKED before 10.6?
Yes. I think it changed because they introduced Airdrop.
Ugh - Airdrop which you have to disable in any decently dense Wifi environment
If I want a video call to work properly I have to:
sudo ifconfig awdl0 downHmm? As far as I know it's not "on" until you open an Airdrop window in Finder.
