What Is Magnet?
Magnet is a macOS utility from CrowdCafé that helps you arrange windows into preset layouts. It is commonly used to snap apps to halves, thirds, quarters, or full screen with drag actions or keyboard shortcuts.
It is not part of macOS itself. It is an add-on productivity app, similar to other window managers for Mac. If you use it regularly, launching it at login can be convenient because its shortcuts and window snapping are available as soon as you sign in.
Is It Safe?
Yes, Magnet is generally safe when it is the real app from CrowdCafé. It is a well-known Mac utility, not a system component and not known for being required by macOS.
On macOS, you can verify it by opening the app in Finder, choosing Get Info, and checking that it is the expected app. You can also right-click the app, choose Open, or review its privacy permissions in System Settings if you want to confirm what access it has. Window managers may request accessibility-related permissions so they can move and resize windows.
If you did not install Magnet yourself, or if an app with this name behaves oddly, review where it came from and remove it if it looks suspicious. The name itself is not a standard macOS background process.
Should I Disable It at Startup?
Usually, yes if you are trimming login items and do not need it immediately. Magnet is optional at startup.
Disabling it from login will not break macOS. It only means Magnet will not be active until you open it manually. If you rely on its keyboard shortcuts or automatic window snapping every day, keeping it enabled at login makes sense.
A good rule: keep it enabled only if you use it in most sessions.
Why Is It Using High CPU or Memory?
Magnet should usually use little memory and very little CPU while idle. If usage is high, common causes include:
- a temporary app hang or macOS glitch
- repeated window events from another app
- accessibility permission issues causing the app to retry actions
- a bug after a macOS or app update
Try quitting and reopening Magnet first. If that does not help, restart your Mac. You can also check whether the issue starts only when using a specific app or display setup.
If high usage keeps coming back, update Magnet through the App Store if that is how you installed it, or remove and reinstall it from a trusted source.
How to Disable or Remove It
To stop Magnet from opening at login on macOS:
- Open System Settings.
- Go to General > Login Items.
- Find Magnet and remove it from the list or disable its background launch entry if shown.
To remove it completely, quit Magnet, then delete the app from Applications in Finder. If you installed it from the App Store, you can also remove it through Launchpad or the App Store-related app management flow on your Mac.

- Will disabling Magnet at startup uninstall it?
- No. It only stops Magnet from launching when you sign in. You can still open it manually any time.
