The eventual arrival of iMessage on OS X, in some form, is almost a foregone conclusion at this point, but a new report claims to confirm that Apple is indeed working on bringing it to the Mac platform alongside AirPlay Mirroring. Citing multiple anonymous sources, 9to5 Mac says Apple is already hard at work bringing the services to OS X, though it is apparently unclear whether or not the efforts will bear fruit. AirPlay Mirroring will theoretically allow OS X users to mirror their Mac display wirelessly to an Apple TV while iMessage will let users carry on conversations from Mac computers just as they can now with the iPhone, iPod touch or iPad. The report says Apple is also currently debating whether or not iMessage should be integrated into Apple’s iChat app or introduced as a standalone app, and a concept video of how the latter scenario might work follows below.
