Fake macOS Apple Loading & Update Prank Screen
Prank Apple users with a highly realistic, fake macOS update loading screen. This simulator features the iconic white Apple logo on a black background, a smooth white progress bar, and a time remaining indicator that mimics macOS system updates.
Since macOS updates can take a long time, this screen is the perfect gag to run on a friend's MacBook when they step away. When they return, they will think their laptop is locked in a long, unsolicited operating system update.
Set the estimated remaining time in the settings panel and enter fullscreen mode to hide the dock, menu bar, and browser tab. The screen will look exactly like a native Apple system reboot.
