Fake macOS Update
The fake Mac update prank throws the black macOS install screen up — Apple logo, thin progress bar creeping across, and the unspoken message: don't you dare touch this. Open it on their Mac, hit fullscreen, and disappear.
Press F11 for maximum realism. Tap or press Esc to exit.
Installed the crack fills the entire screen — no browser bar, no tabs, no giveaway.

- Tap Launch Full-Screen Prank above (or press F11 once it's running).

- When they panic, tap the screen or press Esc to reveal it was a joke.
For laughs only. Nothing here installs, downloads or damages anything — it's all harmless CSS/JS in the browser. It's a staple of April Fools' Day pranks and works any day of the year. Just keep it kind — see what makes a good prank.
