Why Mac window managers ask for the Accessibility permission

Every app that moves other apps' windows needs Accessibility access. What the permission allows, how to grant or remove it, and what to check before you do.

Guide · Updated 13 October 2026

Install any window manager on a Mac and the first thing it asks for is Accessibility access. It is a fair thing to wonder about.

Why it is needed

macOS only lets an app move and resize another app's windows through the Accessibility system, the same one screen readers use. There is no narrower permission for windows alone, so every window manager, from the simplest snapping tool up, needs it.

Granting it, and taking it back

  1. Open System Settings, Privacy & Security, Accessibility.
  2. Turn the app's switch on. You may need your password.
  3. To revoke, turn the switch off or remove the app with the minus button.

What to check before you trust an app with it

  • It is signed by an identified developer and notarized by Apple, so macOS opens it without warnings.
  • Its privacy page says plainly what it reads and sends.
  • It does not also ask you to disable System Integrity Protection.

ClutterFreeMac uses Accessibility to move and resize windows and nothing else. It is notarized, never asks you to change macOS security settings, and its privacy page lists exactly what leaves your Mac and when. Window titles and contents never do.

Questions

Is it safe to give a window manager Accessibility access?

It is the only way any window manager can work. Choose one that is notarized, explains its privacy, and does not ask you to weaken system security.
