This didn't seem to work... Hold down 3 and 2 during boot right? Kismac still froze. What are you quoting?
Did you find any solution to this? Or do you know of any alternative passive scanner for Mac?
If you just need a scanner - iStumbler 99 works just fine.
Not just anything goes in Anything Goes
Agreed with Brian and Osxx. iStumbler for just a WiFi Sniffer is great. I have used it for years. Latest version works fine in Lion.
