Off-topic: How to capture traffic in monitor mode on a Mac

·1 min

It used to be something that couldn’t really be done on a Mac but I have just read through the documentation and it turns out that anything 10.6+ has the ability to automatically put an Airport card into monitor mode.

If you want to give this a go it is as simple as changing the framing mode when capturing on Wireshark, once you start capturing it will put the card into promiscuous mode and you will be able to see all traffic and not just the traffic to/from your machine.
