Ejectit

A macOS menu bar app that automatically unmounts external drives before the system or display sleeps, and remounts them on wake — so you stop seeing "Disk Not Ejected Properly" notifications.

Features

• Auto-unmount on sleep — choose between system sleep, display sleep, or both
• Auto-remount on wake — drives that were unmounted are brought back automatically
• Per-drive toggle — exclude specific drives from auto-ejection
• Manual eject — eject all enabled drives, or one at a time
• Polite-then-force fallback — if a process (e.g. loginwindow) holds a handle, the app retries with unmount force
• Launch at Login — optional, via SMAppService
• No Dock icon — runs as a menu bar utility (LSUIElement)

Requirements

• macOS 13 Ventura or later
• Xcode 15 or later (to build)

Build & Run

1. Open Ejectit.xcodeproj in Xcode
2. Build & Run (Cmd+R)
3. The first time it touches a removable volume, macOS will prompt for access — click Allow

Usage

Click the eject icon in the menu bar to open the panel:

• Eject All — unmount every drive whose toggle is on
• Per-drive switch — enable/disable that drive for auto-ejection
• Per-drive eject button — eject just that one drive
• Eject on: — choose the trigger (System Sleep, Display Sleep, or Either)
• Launch at Login — start automatically on login

Prior art

Ejectit takes its architectural cues from nielsmouthaan/ejectify-macos — a feature-rich Swift/AppKit menu bar app with a privileged helper, IOKit power notifications, and Disk Arbitration. Ejectit is a leaner SwiftUI take on the same idea, using MenuBarExtra for the UI and diskutil + NSWorkspace/IOKit notifications for the actual work.
