The app is still in its early stages, but most of the base functionalities of Messenger are there. The interface is nearly identical to what you would find on Messenger.com and Facebook’s other Messenger apps.

As far as bugs go, the ability to upload images is current non-functioning and support for notifications is nowhere to be found. Although team member Josh Puckett says that they are currently working on notifications and badging.
Facebook Messenger for Mac is available as a free download here. Expect updates to come relatively quickly, so be sure to be on the lookout for bug fixes and feature additions.
