Mac users can download office productivity software for free, thanks to OpenOSX.

OpenOSX is celebrating its fifth birthday by offering a free OpenOSX Office download with every order for the next two weeks.

OpenOSX was among the first firms to package single-click solutions to install open-source imaging applications The Gimp and GRASS on Mac OS X.

Over five years ago, Jeshua Lacock, the owner of OpenOSX, ported GRASS GIS 5.0 beta to Mac OS X public beta. Responding to demand he then developed a single-click installation package.

The company offers a range of products for sale, such as ReadyStream 1.0.0: this includes The Gimp and CinePath along with a range of open-source multimedia applications and costs from $30.
