Keeping the prompter out of your recording
Short version: capture a window, not the whole screen.
Why it has to work that way
Apps used to be able to ask macOS to leave a window out of screen recordings. MiniPrompter still asks, and on macOS 15.3 and earlier it is still honoured.
From macOS 15.4 onwards it is not. Apple's own developer support has confirmed there is no public way for an app to keep itself out of a screen capture any more, and every modern recorder — OBS, Zoom, Teams, QuickTime, ⇧⌘5 — uses the new system that ignores the request.
No Mac teleprompter can do it. If you see one claiming it can, it is describing how things worked a few years ago.
What to do instead
Capture the window, not the display. This is the reliable answer and it is what most people who record for a living already do.
- OBS — use a Window Capture or Application Capture source pointed at your slides, browser or whatever you are presenting. MiniPrompter is a different window, so it simply is not in the shot.
- Zoom, Meet, Teams — when you share, choose the specific window or the specific application rather than "Entire Screen".
- QuickTime — record the camera rather than the screen, and the question does not arise.
Or put it on the other display. If you have two, keep MiniPrompter on the one with the camera and capture the other. The script window and the fill light can live on different displays, which is exactly the arrangement this needs.
The menu bar icon
MiniPrompter's icon sits in the system menu bar, and that is owned by macOS rather than by MiniPrompter. A recording of the whole display will include it, and there is nothing the app can do about that.
If you record full-screen and want it gone, macOS can hide the whole menu bar for you: System Settings › Control Centre › Automatically hide and show the menu bar. Capturing a window rather than the display sidesteps it too.
The fill light
The fill light is drawn on your screen, so a full-display recording captures it along with everything else. Capturing a window leaves it out, same as the script.
If you are recording your camera rather than your screen, none of this applies — the fill light just lights you, which is the point.
