After iPhone/iPodTouch, it seems that BoxCar has decided to expand their services beyond the platform, that’s why, they have come up with a Mac OS X client that keeps you updated about the notifications of your favorite social networking sites, emails, applications recommendations and so on. If you earlier had a BoxCar account on iPhone/iPodTouch, you can use it for Mac OS X client as well and all of your added services would be uploaded within a few minutes. However, you can also add other from the official BoxCar website. BoxCar client for MacOSX is currently not available on MacAppStore. George say’s that Apple requirements for the App Store make testing difficult. It’s expected that the Mac App Store release will be soon.
You can download the client from here
