It only took a year, but Valve's Steam Link app finally arrived in the App Store for both iOS devices and Apple TV. Apple originally partially rejected it because you can buy games through Steam with the design without Apple cutting it off, so only our friends on Android devices have enjoyed the feature in the last 12 months.
But now that's all behind us. Now that Steam Link is here, it's a great way to enjoy playing your Mac or PC games with the relative freedom and comfort of an iPhone or Apple TV – at least if you have a strong connection . We will first tell you what you need before you jump into a game, and then we will guide you through the steps of setting up the game. We also help you solve problems. This was a long time ago, so let's not waste any more time!
This is what you need
You may have heard of Steam & # 39; s separate Steam Link hardware, but don't worry – you don't need it if you plan to go to an iOS device or have an Apple TV. In addition to the controller, you probably already have everything you need.
An iPhone or iPad with at least iOS 10 or an Apple TV
A host iMac or MacBook, or a PC that runs Windows or Linux. Regardless of the system, Steam must also be installed.
(Highly recommended.) A Steam controller or an MFi controller. We recommend the Rotor Riot, as this is the only MFi controller that currently supports the commonly used "L3" and "R3" thumbstick buttons.
Both the host computer and the iOS device / Apple TV must be on the same network.
Valve says that you get the most out of the Steam Link app if your host computer is connected with an Ethernet cable and a 5 GHz WiFi router (although we think a 6 GHz router is preferred). Your Apple TV or iOS device must also be on the same 5GHz network. You also get better results if you keep your iOS or Apple TV device close to the router.
Again, you need a strong connection if you expect Steam Link to work remotely as it should. And even at its best, Steam Link gaming is not as popular for games that require fast, "convulsive" reaction times, such as first-person shooters. Unless you have a Google Fiber connection or something similar, it is currently best suited for games with a slower pace that are not affected by the inevitable delays.
Setting up Steam Link on iPhone, iPad and Apple TV  The emphasis here is on the iOS version, but the steps are about the same for the Apple TV. You just have to search for the Steam Link app in the tvOS App Store.
1. Turn on your Mac or PC and open Steam and make sure that both the iOS device (or Apple TV) and the host computer are connected to the same network.
2. Download the Steam Link app to your iPhone and open it. Here is the link for iOS, but on tvOS you must navigate to it via the Apple TV App Store.
3. Once the app is open, press the large blue button Getting Started . The Steam Link app then searches for computers on the same network.
4. A menu for Pair Controller appears. If you have an MFi controller or a Steam controller, go ahead and connect it, and Steam Link immediately goes to the next step. (If you have already connected a gamepad, Steam Link skips this step.) You can use touch controls on iOS, but they are awkward – and you need a controller on Apple TV. However, if you want to live dangerously on the iPhone, press Use touch control and Steam Link proceeds to the next step.
5. Press the name of the computer that you want to use as a host from the list.
6. You will see a pin code appear in the Steam Link app on your iOS device or Apple TV.
7. On your host computer you must also see a pop-up of Steam with the title Authorize device . Enter the PIN code of your iOS device in this prompt. Press OK .
8. The Steam Link app on your iOS device then tests your connection and tells you the types of streaming speeds you can expect. Press OK when it is complete.
9. On the next page you want to see three check marks for your host computer, your controller and your connection. You only get a check mark for your connection if you get download speeds of at least 100Mb / s. (This will be the biggest hurdle for most people, although you can still play with a weak connection.)
10. If you are completely cool about this, press Start playing .
Here you can encounter a few speed bumps. If you use an MFi controller, Steam shows you shortcuts for standard game pad controls that normally cannot be used with MFi controllers. Again, the Rotor Riot is one of the few exceptions. If you have chosen touch controls, Steam Link shows you the even more complex shortcuts. Press Continue .
Steam may need to download new driver & # 39; s. If this is the case, you will see a warning on your iOS device that says, "Streaming requires additional driver installation. Follow the Steam directions on the remote computer." On the Mac / PC, a window appears in Steam with the text To: "Gamepad driver update: Steam needs to update its gamepad driver, which may cause the system to restart." Press Install on the bottom right and follow the steps. On a Mac, you may need to allow the installation to bypass your security settings. You also need to restart your Mac. Once this has happened and you have reopened Steam, press Start playing again on your iOS device.
11. On the host computer, Steam must be opened in Big Picture mode – the game pad friendly mode – and the feed must also start streaming to your iPhone, iPad or Apple TV. Search for your games under Library and play them!
12. To end streaming on Steam Link, press the Menu button (or equivalent) on your MFi controller and go to the power symbol at the top right of the Big Picture interface. Press it.
13. You see a few options. If you want to immediately disable Steam Link on your iOS device or Apple TV, press Stop streaming . Steam Link should then close. If you do not disable Steam Link in this way and try to close the app on IOS, the Big Picture mode will continue to play on your Mac or PC and you must disable it separately there.
