I confirm that my A5 Pro+ is not automatically detected by Lightburn using the button “Find My Laser”, but works using “Create Manually”. This is weird I concur. I have a MacBook Air M1 with macOS Monterey 12.5, and I connect the Atomstack to the Mac using the USB-A to USB-B cable provided in the box and an Apple USB-C to USB adapter.
I will try again a direct connection without adapter when I buy a USB-B to USB-C cable. But it seems that such cables only exist unshielded, with no ferrite. Another oddity.
EDIT: It seems there is really an issue with this machine and current macOS, see the various posts on the same subject:
I give only three, there are others.
Atomstack says this machine is compatible with macOS when using Lightburn. It’s in the web site and the manual that comes with the machine.
All solutions provided in the Lightburn forum consist of asking to configure the machine manually.
