I'm using Alfa AWUS036NH, Wireshark 1.8.4 and Mac OS 10.8.2. I can't set monitor mode, that's what I get:

a disabled checkbox :(

Is there any way to turn on monitor mode with this card and mac os?

best regards, Rorax

As far as I know, this only works with AirPort Extreme adapters.

You could run BackTrack Linux in a virtual machine and map the USB device to that virtual machine. A lot of people do exactly that.

Yes. Sadly, the IO80211* classes in IOKit are private, so third-party network drivers have to be Ethernet drivers; this means that third-party 802.11 adapter drivers can't expose any capabilities other than those offered by Ethernet adapters, including monitor mode support (which involves supplying 802.11 headers rather than Ethernet headers - from userland, requesting monitor mode is done by selecting one of the 802.11 DLT_ values with a BIOCSDLT ioctl on the BPF device).
