Facebook Messenger's desktop versions for Mac and Windows have officially ceased operations. Users attempting to access the app will be redirected to the Facebook website or the Facebook desktop app, depending on their operating system. Mac users will be directed to the Facebook website, while Windows users will be directed to the Facebook desktop app, where they can continue their conversations with the same features. Messenger users without a Facebook account will be redirected to Messenger.com to log in. Concerns about chat history are addressed, with Meta stating that chat history can be saved if users took the necessary steps to ensure secure storage was enabled before the cutoff.
