I, personally, needed a WhatsApp for Mac for too long! After a year since Facebook purchased WhatsApp for an astonishing amount of money, WhatsApp have finally decided to release their desktop app for Mac and Windows PC. Although they let us use the browser version back in 2015, it did lack some key feature — convenience.
You can download it now for Mac or PC form their official website (weirdly not from the Mac App Store!).
