And as they click on the icon the same error message appears as the Mac is unlocked. The icon appears like the 2 rectangles above one another in the top-right corner of the Mac OS screen.
Your Screen is Being Observed on MacĪlong with the error message the users get an “ overlapping squares” icon in the Apple status Menu Bar. As per the users, the error message appears on Mac’s lock screen, the screen appears before logging into the Mac OS. If you continue to have trouble with the shortcut, or you’d rather have more general display options visible from anywhere, you can use a free third party utility that adds the Displays menu bar item back to Mac OS X.Many users are seeing the “ your screen is being observed” error on their Mac OS. Unless the Mac supports the same resolution, that’s hard to avoid with those screen types, but old fashioned CRT’s and any projector should be immune from those effects.ĭo note that some Macs and keyboard layouts may require the usage of ALT+Command+F1 to get the Mirror toggle to work.
This means that some external displays, typically LED, LCD, and HDTV’s, will often not run at their native resolution, which leads to fuzzy looking images on that external display as it mirrors the native resolution from the Mac. Something to consider with screen Mirroring is the resolution of the external display, which is often different from the resolution set on a MacBook Pro or Air.
Use this the next time you need to do a presentation, or watch a movie on a bigger screen, it’s super fast. This command works with quite literally any Mac, whether a MacBook Pro, Air, iMac, whether it’s using a built-in or external keyboard, and with any connected secondary display, from an external monitor, a TV, a projector, Apple TV through AirPlay Mirroring, whatever. In order for this shortcut to work you will need an external display of any sort attached, then once hit hit Command+F1 you will see both displays briefly flicker bright blue and suddenly mirroring will be enabled.
