Is a driver required on all Mac OS?

LightBurn Hardware Compatibility Atomstack

I’m running an Atomstack A5 40w on a PowerBook using Monterey. I set-up Lightburn without installing a driver and it ‘found laser’ no problem. A few homing issues aside (until I disabled autohome) think I’m ready to begin some engraving tests.

My question is: do you recommend I install the CH34X driver anyway? PDF notes for the driver suggest Monterey requires some additional steps on install (in Terminal) and it feels like that’s inviting trouble …

Hi John and welcome!

You don’t usually need to install any drivers on MacOS. Since your Mac connected to the laser, it’s clearly not required.

If your machine does not have homing switches, keep Autohome disabled and be aware of this:
