I have a standard license for my CO2 machine, and have updated to the fiber license ($90). I have deactivated and reactivated the license key, but the software is not finding my fiber laser. Mac 12.7 Monterey.
This should eliminate the hardware. I’d suggest you check the permissions to ensure you have access to the device… I don’t know how to do that with the Mac.
I’d conclude it’s a protection issue you’re up against.
If you can run Lightburn as root and it connects, then it’s likely a protection issue.
You can always go out to the license portal and it should show that a fiber is authorized to you.
