BlackBerry Desktop Manager for Mac hit the airwaves recently, and we’ve seen no shortage of reviews. The application is pretty straight forward, though it lacks a few features of the PC version. One is the ability to install unofficial OS upgrades. But, like all things Berry, someone has created a workaround.
