The macOS “Installing a software update…” screen on a black background: the ring-and-glyph emblem, a slim white progress bar and an “About N minutes remaining” estimate that keeps politely resetting. A calm, convincing Mac holding screen that never actually finishes — and installs nothing.
What you can do with it
- A harmless “my Mac is stuck updating” prank
- A believable macOS holding screen for videos and films
- An ambient “please wait” screen for a spare Mac display
How to use Mac Update
Open Customize to set the colours, title and behaviour, then press Fullscreen (or add ?present=1 to the URL) for a clean, controls-free screen. To run it unattended on a stream, copy the OBS browser-source URL; to drop it into a web page, use the <iframe> embed. Everything is a visual prop — no real hacking, network or data.
Is my Mac really updating?
No. Nothing is downloaded, installed or changed — it is a full-screen picture of the macOS update screen with an animated progress bar. Press Escape to leave.
Can I switch it to Windows?
Yes. Open Customize and change the update style to Windows 11 or Windows 10; the emblem, bar and wording switch to match.
