Sorry, it's
hw.apic.0.disabled=1
I missed the 'd'. It's not a sysctl, it's a tunable (they share the
same namespace and often overlap, but not always). kern.smp.disabled
works too. You'll need to either put these settings into
/boot/loader.conf, or manually set them in the loader by hitting the
space bar during the 10 second timeout. 5.x had a nice menu for doing
this, but it because controversial over silly reasons and was removed.
