ScreenBlur 1.0.0
Blur part of your screen while you share it. Draw a zone over what nobody needs to see — it stays hidden for the whole screen share. A zone can be fixed on screen, attached to one app and follow its window, or you can hide a whole app.
macOS 15 Sequoia or later. Download ScreenBlur-1.0.0.dmg.
First launch
The app is signed but not notarised by Apple, so macOS will refuse to open it ("cannot verify the developer"). Dismiss the message, then System Settings → Privacy & Security, scroll to the bottom, Open Anyway. The right-click → Open trick no longer works since Sequoia.
The one thing to know
Sharing your whole screen shows the masks. Sharing a single window does not — the call captures that window alone and no tool of this kind can insert itself into that capture. Share the whole screen, or check first with Aperçu de ce que voient les autres… in the menu.
Permissions
None to get started. Frosted glass and opaque masks need nothing at all; adjustable blur and pixelate reread the screen and ask for Screen Recording. Window tracking and the global shortcuts (⌥⇧N, ⌥⇧B) need no Accessibility permission.
The interface is in French for now.
Flouter une partie de son écran pendant qu'on le partage. Une zone fixe, une zone rattachée à une application qui suit sa fenêtre, ou une application entière. Aucune autorisation n'est nécessaire pour commencer.
