Hi,

Just thought I'd make a post to help anybody struggling with the same issue I was. I was trying to use SteamLink on my Apple TV 4K and every time it was connecting to the Windows PC running steam it would crash it and never load properly.

I scoured the net for solutions and found that a common fix applied to non-Apple devices works for Apple TV too.

Open Steam, go to settings > remote play > advanced host options - Now uncheck "enable hardware encoding"

Give it a try, hopefully it helps some people, it fixed it for me and my SteamLink is running fine now.
