Mick, Good job on KisMAC! System Notes: System Version: Mac OS X 10.3 (7A202) Kernel Version: Darwin 7.0.0b1 AiroJack driver works fine with 005f but no go with 005f1. See below. Has anyone been successful with GPS on 10.3 pre-release? ___Other Notes____ KisMAC005f1.zip -- Cisco driver start failed with problem (you're not root). I installed scripts SUID but no go. Maybe something fluky here. Keyspan USB to SERIAL: -- Has anyone else noticed that the Keyspan USB to Serial Installer doesn't work in 10.3 pre-release. Anyone successful? UC232A USB to SERIAL: -- Found this page that was helpful in setup for 10.2: http://www.osxhax.com/archives/cat_miscelaneous_hacks.html Look for section-- IOGear -232A USB serial dongle under OS X. Looks like the UC232A driver also doesn't work in 10.3 Cheers, Rob
