It only took a year, but Valve's Steam Link app has finally come to the App Store for both iOS devices and Apple TV. Apple rejected it in part, because its design allows you to buy games through Steam without letting Apple get its cut and so only our friends on Android devices have been able to enjoy the feature over the last 12 months.
But now everything is behind us. Now that Steam Link is here, it's a great way to enjoy playing 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 start by telling you what you need before you jump into a game, and then we go through the steps to set it up. We also help with troubleshooting.
Here's what you need
You may have heard of Steam's separate Steam Link hardware, but don't worry – you don't need it if you plan to stream to an iOS device or have an Apple TV. Besides the control, you probably have everything you need.
An iPhone or iPad running at least iOS 10 or an Apple TV
A hosted iMac or MacBook or a computer running either Windows or Linux. Regardless of the system, Steam needs to be installed as well.
(Recommended.) A steam control or a MFi controller. We recommend Rotor Riot, as it is the only MFi controller that currently supports the standard "L3" and "R3" thumb buttons.
Both the host computer and the iOS device / Apple TV must be on the same network.
The valve says you get the most out of the Steam Link app if your host is connected to an Ethernet cable and a 5 GHz Wi-Fi router (although we find that a 6GHz router is preferred). Your Apple TV or iOS device must also be on the same 5GHz network. You'll also get better results if you hold your iOS or Apple TV near the router.
Again, you need a strong connection if you expect Steam Link to work even remotely as it should. And even at best, Steam Link games are not so good for games that require fast, "quick" reaction times, which for the first time shooters. If you don't have a Google Fiber connection or something like that, it's currently best suited for slower games that aren't affected by the inevitable delays.
How to set up Steam Link on iPhone, iPad and Apple TV  The focus here is on the iOS version, but the steps are about the same for Apple TV. You just need to search for the Steam Link app on the tvOS App Store.
first Turn on your Mac or PC and open Steam, making sure both the iOS device (or Apple TV) and the host are on the same network.
2nd Download the Steam Link app for 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.
3rd When the app is open, press the large blue Getting Started button. The Steam Link app then searches for computers on the same network. Steam link is started ” width=”1200″ height=”604″ data-imageid=”100796666″ data-license=”IDG”/> Leif Johnson
4. A menu for Pair Controller will appear. If you have an MFi controller or a steam controller, continue and connect it, and Steam Link goes straight to the next step. (If you've already connected a gamepad, Steam Link will skip this step.) You can use point controls on iOS, but they are unpleasant – and you will need a controller on Apple TV. If you want to be dangerous on iPhone, press Use the touch screen and Steam Link will move on to the next step.
5. Tap the name of the computer you want to use as the host from the list.
6. You will then see a PIN that appears in the Steam Link app on your iOS device or Apple TV.
7. On your host computer you should also see a popup from Steam titled Authorize Device . Enter the PIN number from your iOS device at this prompt. Press OK .
8. The Steam Link app on your iOS device then tests your connection and tells you what type of flow rates you can expect. Press OK when finished.
9. On the next page you will see three check boxes for your host computer, your controller and your connection. You will only get a check mark for your connection if you get download speeds of at least 100 Mbps. (This is the biggest obstacle for most people, even if you can still play with a weak connection.)

10. If you are cool with all this, press Start Playing .
Here you can encounter a couple of speed bumps. If you are using an MFi controller, Steam will show you shortcuts to accommodate standard gamepad controls that cannot normally be used with MFi controls. Once again, the rotor ramp is one of the few exceptions. If you have selected touch screens, Steam Link will show you the even more permeated shortcuts for them. Press Continue .
Steam may need to download new drivers. If so, you'll see a warning on your iOS device that says "Streaming requires additional driver installation. Please follow the Steam instructions on the remote computer." On Mac / PC, a window should appear in Steam that says "Gamepad Driver Update: Steam Needs update its gamepad driver, which may require the system to restart. "Press Install at the bottom right and follow the steps. On a Mac, you may need to allow the installation to bypass your security settings. You should also restart your Mac. When this is done and you have opened the Steam, press to start playing again on your iOS device.
11. On the host computer, Steam should open in the Big Picture mode – it's gamepad-friendly mode – and the flow will start streaming to your iPhone, iPad or Apple TV as well. Find your games under Library and play them!
12. To end streaming on the steam link, press the menu (or equivalent) on your MFi controller and then scroll to the energy symbol at the top right of the image interface. Push it.
13. You will see some options. To immediately turn off Steam Link on your iOS device or Apple TV, press Stop Streaming . Steam link should then be closed. If you do not turn off Steam Link this way and try to force the app to shut down on the iOS, the Big Picture mode continues to play on your Mac or PC and you need to disable it separately.
