For those who don’t have a Microsoft machine but want the ability to snap windows to either side (or corner!) of their screen: Spectacle is here.
Spectacle is am open source window management app that moves and resizes windows with ease. Upon installation, it requires enabling accessibility, but after that, it just works.
Unlike with Windows, you can’t merely drag and snap windows to various regions; Spectacle runs via hotkeys. You can change any of these key combinations by going into preferences and setting each to your liking. There is even a guide at the bottom of the window to help decipher each shortcut symbol in case of confusion. And if you happen to mess up, there’s always the option to reset.
Clicking the arrow beside the symbols at the bottom also allows you options to launch at startup, and run either in the menu or as a background application.
In the main Spectacle menu, you can also disable it for the current window, such as your browser or word processor.
For a free and open source application, Spectacle is both robust and light on system resources. It can’t do fancy effects or overlays, but there is power in simplicity and Spectacle pulls it off.
