Excellent window manager. I have used several window managers over the years and this one is the best I have used. It is easy to use and very customisable.

Unfortunately this app has a hard time with Firefox Developer Edition. since that is my primary browser I'm afraid this app doesn't do much for me.

I have been a user of the original Mosaic for several years and it is an essential - no hype, just facts - part of my daily workflow. I use it every few minutes to reconfigure my display as my activities change.

This is the first thing I install on every Mac I use. Seriously, it's gotten to the point where I can't imagine using macOS without it. Rectangle is a free, open-source app that supports macOS 10.13+ and both Intel and Apple Silicon. I'm always down for free and open-source, so that's a big thumbs up from me. But what makes Rectangle a must-have for me is the convenience it brings.

Detailed Review

Mosaic Pro is a macOS window manager designed to simplify the process of resizing and positioning application windows. It aims to provide a seamless and intuitive experience, feeling like a natural extension of macOS. Users can arrange windows using drag-and-drop, keyboard shortcuts, and even the Touch Bar on compatible MacBook Pro models. Mosaic offers highly customizable layouts, allowing users to create their own window arrangements beyond simple presets using grid-based basic layouts or constraint-controlled advanced layouts. Layout Groups help organize layouts for different workflows.

Standout Features

  • Drag & Drop Window Management: Easily resize and reposition windows by dragging and dropping them onto predefined layouts.
  • Customizable Layouts: Create basic grid-based layouts or advanced layouts with precise size and location controls.
  • Layout Groups: Organize layouts for specific workflows and switch between them to filter layouts.
  • Keyboard Shortcuts: Apply layouts and access features quickly using customizable keyboard shortcuts.
  • Touch Bar Support: Access layouts directly from the MacBook Pro Touch Bar for quick window arrangement.
  • Mosaic Remote (iOS App): Control window layouts from an iPhone or iPad using the companion iOS app.
  • Quick Layout & Positions: Define single-use layouts on the fly and quickly move windows to screen corners or edges.

Conclusion

Mosaic Pro is a powerful and user-friendly window manager for macOS that enhances productivity by streamlining window organization. Its customizable layouts and multiple control methods (drag & drop, shortcuts, Touch Bar, iOS app) cater to various user preferences. While it offers a free 7-day trial, it is a paid application with one-time purchase options for Standard and Pro editions, and is also available via Setapp subscription. Users seeking a feature-rich window management solution with a focus on customization and seamless macOS integration will find Mosaic Pro a valuable tool. However, users looking for free, actively updated solutions might consider alternatives like Rectangle or Magnet.
