In my experience: The mac kernel intermittently locks up during single-step kernel debugging. This has been an issue since well before 10.12, at least going back to 10.6 .

Using breakpoints instead of single-step mostly avoids the kernel debugger lock-ups, but still happens occasionally. For issues where breakpoints don't cut it, things can be pretty frustrating.

I can confirm all of the above and will add: it seems to be a little more reliable over Firewire versus Ethernet. Plus, commands with large output (showallthreads and such) tend to run much faster. These days, using Firewire means a multitude of dongles, but what can you do. It'd be nice if you could do it via a direct Thunderbolt connection or if macOS started supporting the special USB 3.0 A-to-A debug cable that can apparently be used for debugging the Linux and Windows kernels.
