I have tried drawing on the black screen, and I can see input showing on my Mac screen.
My Mac been has not been restarted to Safe mode recently.
I am not using any programs like Parallels, nor any external displays attached to my Mac.
I tried the factory reset for Astropad. There wasn’t any difference - the issue still persists.
– If you try drawing on the black screen, does any input show on your Mac screen?
Has your Mac been restarted to Safe mode recently?
Are you using any programs like Parallels? Or any external displays attached to your Mac?
Try factory reset for Astropad—
Close Astropad’s Mac app.
Then hold Option/Alt key, while opening the Mac app again.
It will ask if you want a factory reset.
Let us know if there is any difference, or if the issue persists.
