Noject vs. Ejectify
Ejectify automatically unmounts the volumes you select when your Mac sleeps, the display turns off, the screen locks, or the screensaver starts, then remounts them on wake, to avoid "disk was not ejected properly" warnings. Noject keeps permanently-plugged drives mounted and blocks accidental ejection.

Where Noject wins
- Blocks every eject and unmount attempt on protected volumes, whether from Finder, Disk Utility, Terminal, or a third-party app.
- A background agent enforces protection even when the UI is closed, and survives reboots, sleep, and reconnects.
- Remembers protected volumes by UUID and re-arms automatically when a drive is plugged back in.
- One-shot "Eject Once (bypass)" for the rare time you genuinely need to eject, without losing your settings.
- Private by design: no account, no telemetry, and it never reads or writes the data on your volumes.
Where Ejectify wins
- Automatically unmounts selected volumes on sleep, display off, screen lock, or screensaver.
- Remounts volumes again when the Mac becomes active.
- Lets you choose exactly which volumes it manages; supports external drives, removable internal media, and disk images.
- Available in 30+ languages, with an optional privileged helper and a force-unmount option.
Best fit
Choose Ejectify if...
You want selected external drives to be cleanly unmounted while the Mac sleeps or the display is off, and remounted on wake, typically to avoid improper-ejection warnings.
FAQ
Common questions
Is Ejectify an alternative to Noject? +
Not really, because they aim at opposite outcomes. Ejectify unmounts external drives when your Mac sleeps; Noject keeps chosen drives mounted and blocks accidental ejects. Pick Noject when a drive should always stay mounted.
Which should I use for a Mac mini or Mac Studio with a RAID array? +
Noject. Desktop machines with permanently-plugged storage usually want the array to stay mounted, and the real risk is an accidental eject rather than a sleep unmount.
Can I run both? +
It is possible, but they pull in different directions on the same volume. If a drive must never be unmounted, protect it with Noject and do not let a sleep-unmount tool manage that volume.
