App Won't Quit

Closing a window does NOT quit the app on macOS. This is intentional: apps reopen faster when they stay in memory.

How to Actually Quit

• Cmd + Q: quits the app
• Right-click Dock icon → Quit
• Cmd + Tab to the app → Cmd + Q

Force Quit (Frozen Apps)

• Cmd + Option + Esc: opens Force Quit dialog
• Or: right-click and hold on the Dock icon → Force Quit appears
• Terminal: killall AppName

Known Traps

• Red button (X) in Safari, Finder, etc. closes the window but the app runs in background
• Look for the small dot under Dock icons: that means the app is still running
• Finder can't be quit. It's always running.
