Important Note
This project is not being actively maintained. Unfortunately, after almost a decade of on-and-off development I can no longer dedicate the time needed to be a responsible maintainer of this project. Spectacle will remain available for download but please use at your own risk. The source code will continue to be free and open to anyone, so feel free to make Spectacle your own.
Thanks to all the folks that have made Spectacle the first app they install a new Mac!
Spectacle users have recommended Rectangle as an open source alternative.
System requirements
Spectacle [0.8.6][1] is the last version to support Mac OS X 10.7; future releases will only support 10.9 or greater. Folks wishing to stay on 10.7 should download [0.8.6][1]. Those looking for a version of Spectacle that supports 10.6 can still download [0.7][2].
