I'm going to sound like a broken record,hbo max/tv sign in but the truth is the truth.HBO Max is available on Apple TV streaming devices too,and just like Roku and Fire Stick,downloading the app couldn't be easier:Find the App Store on your Apple TV Search for"HBO Max"Once you see it,select it and press the download button Once that's done, it should be accessible from the list of apps on the Apple TV.And again, Apple TV has Siri support and Siri can help you find HBO Max or any other app if you just ask.Vizio SmartCast TVs are a bit of a different animal, but believe it or not, it's actually easier than all of the above options to watch HBO Max on one of these devices. That's because SmartCast doesn't really ask users to add or remove apps as much as it pre-installs any apps that Vizio comes to an agreement with.HBO Max happens to be one of those. Simply go to the app selection in your SmartCast TV and you should find it.
