The steps for debugging a kernel panic are pretty much the same as before. You’d need the kernel debug kit.
If you intend to use 2 machine debugging over the thunderbolt firewire adapter, you’ll need to set the nvram on the test machine to
nvram boot-args=“debug=XXXX kdp_match_name=firewire fwkdp=0x8000 fwkpfv=0x8000"
Hope that helps,
David

Can anyone give me a set of steps for debugging using lldb assuming I have the kernel panic log, similar to what's defined here (https://developer.apple.com/library/mac/technotes/tn2063/_index.html#//apple_ref/doc/uid/DTS10003091-CH1-SECTION9)? Thanks for any help.
