Hi,
i am aware of the need to give OBS display capture permissions in system preferences, and i did so.
Indeed, i reopen OBS, add screen capture, and it works beautifully.

The problem arises when i close OBS and reopen it : in the auto-saved scene, Display Capture shows black screen and the display tab says 'device not connected or available'.

the only way to make it work again is to delete the source and readd a new Display Capture from scratch. It works as expected, then when you close and reopen OBS you still get the black screen, so you always have to readd the source when you close OBS.

This is the log:

Hi,

Have you guys found a solution for this problem?
I am having the same issue.

I configure the Display Capture and it works fine.
As soon as a close OBS and reopen it, the display capture shows me a black screen.

What is weird is that, if I then plug an external monitor to my Macbook Pro 16, OBS starts correctly & the display capture works correctly as well.. Even though the display capture is configured to show the built-in monitor.

I would really appreciate some guidance/help here.
This issue is driving me insane.

Thank you.

I upgraded my mac to "Big Sur" and had the same problem.
I managed to remove and add a new scene.

Hi - I have the same issue, I temporarily fixed it by making a whole new scene but as soon as I closed and re opened OBS it was broken again. Same as above OBS has full permission to screen record so I've no idea what the issue is, but it's only cropped up since upgrading to Big Sur.

I have upgraded to big sur today and noticed this straight away. Is there any ETA on a fix as it seems to have been around for a long time?

The workaround also works for me however the process is too long for my setup so using quicktime for recordings in the meantime.

This is hitting me, too, in exactly the same way. I have to re-add the display capture every time. A fix would be great! Thanks.
