Granted screen recording access but the Mac recorder still says it is needed

You turned iRecord on in System Settings, came back, and the app still shows Screen Recording access needed or still records a black screen.

Cause. macOS gives an app its screen access at launch. A copy of the app that was already running when the switch was flipped keeps the answer it was given when it started.

Fix

1. Quit iRecord completely — ⌘Q, not just closing the window.
2. Open iRecord again.
3. Open the New Recording window. The row is gone and the Record button is enabled.

If the row is still there after a restart, check that the switch you turned on is under Privacy & Security → Screen Recording and that it is iRecord, not another app with a similar icon. Camera and microphone access take effect immediately and do not need a restart.
