I built a macOS app that bricks your Mac for 30 seconds so you can clean it

说明与用途

WashMyMac 是一款 macOS 工具，显示黑屏并阻止所有输入，允许用户安全、高效地清洁 MacBook 屏幕，避免意外快捷键触发。

问题

Cleaning a MacBook’s screen is difficult because the display remains active, making fingerprints invisible and risking accidental input during wiping.

结果

WashMyMac enables safe, efficient screen cleaning by providing a black overlay that blocks all input and guarantees a safe exit, eliminating accidental shortcuts and making fingerprints visible.

工作流

• Launch WashMyMac via ⌃⌥⌘W or menu bar
• The screen turns black and all input is blocked
• Wipe the screen freely
• Exit by holding ⌃⌥⌘U for 1.5 s or use the auto‑exit after 5 minutes

证据

Every display goes flat black. Keyboard, trackpad and mouse go dead — including ⌘Space, ⌘Tab, ⌘Q, volume, brightness and trackpad gestures.

The rule: ⌃⌥⌘U counts only when exactly those three modifiers and U are down. Not one extra key.
