Moom overview

Moom allows you to move and zoom windows - using either the mouse or the keyboard - to predefined locations and sizes, or to full screen mode.

When used via the mouse, all you need to do is hover over a green resize button, and Moom's interface appears. When used via the keyboard, press your defined shortcut, and the Moom keyboard bezel appears; you can then move windows using the arrow keys and modifier keys.

Moom can be run as a traditional application, a menu bar application, or a completely faceless background application.

What's new in version 4.5

New Features

Applying a layout can now optionally hide any apps that aren't part of the layout.
On macOS 13 and newer, there is now a general setting that makes Moom leave room for Stage Manager's sidebar. In other words, with the setting enabled, Moom will subtract the Stage Manager sidebar from a given display's usable area, just like the menu bar and Dock are subtracted. Note, though, that if Stage Manager is currently invisible, Moom will assume that that's what you want and act as if Stage Manager weren't enabled.

Bug Fixes and Improvements

Updated the action chooser's look for macOS 26.
Worked around two inconsistencies in how macOS 26 draws pop-up buttons.
On macOS 13 and newer, Moom now uses a more modern mechanism to add or remove itself from your login items as you check or uncheck its corresponding setting. (This is a behind-the-scenes change that ideally won't be noticeable.)
On macOS 26 and newer, Moom no longer offers to treat drawers as part of their parent windows for positioning purposes. macOS 26 broke the underlying functionality, but thankfully, that's not too much of a problem, since barely any apps use drawers anymore.
