Why can't I use Wechat on my Imac with Mavericks? The app assumes I've already got a Wechat login, but I do not have an iphone. I ONLY want to use Wechat on my Imac! Was told to go to "Bluestacks" and download some emulator...did this and then one is supposed to search for THEIR app for making the Wechat app work. search function there reveals a blank screen. Frustrated.
