Since I move a bunch of USB devices between my personal and work MacBooks anyway, I just wired my Magic Keyboard and Trackpad up to the same KVM switch and that works fine. However, it wouldn’t work for a Magic Mouse if I decided to use that, so I’ll give Magic Switch a try (especially compelling since it doesn’t require the same Apple ID as Continuity does). I’d like to see if I can wire it up to switch when the KVM switches from one laptop to the other.
