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.

The preboot partition contains the code which handles the login for an encrypted drive, after that is successfully unlocked it is handed off to the main OS. The screen capture service is a system-wide service (not a per-user service) and system-wide services should only be modifiable by an administrator. Starting with macOS Big Sur, granting access to screen recording will require admin authentication.
