Updating…

What is it

A convincing full-screen “system updating” display. It detects your OS and applies the matching UI: Windows dot-spinner blue screen, macOS dark progress bar, Linux (Ubuntu) update page — or switch manually. Progress eases upward and gets stuck at 99% forever; duration can be set to 15/30/60/120 minutes, perfect for a lunch-break slack.

Highlights

• Auto-detects Windows / macOS / Linux and applies the matching update screen
• “Do not turn off your computer” + changing step messages
• Eased progress that stalls at 99%; adjustable duration (up to 120 min)
• Fullscreen, no giveaways; Esc / triple-tap the top-left corner to exit
