jri: Assigning to you. Specifically interested in whether the OSX API for TFO addresses some of the concerns raised when trying to use the Linux TFO API in Chrome.

cbentzel: It should be better. I have spoken with the Apple devs, and the API is quite close to what I proposed for Linux. I won't get to this in a rush, but I'm happy to take it on.
Is there any update on this? Chrome 56 macOS still no TFO support :(

I'd love to see update on this. It will be very useful for my use case. Really need this feature.
Chrome 59 on macOS 10.12 still does not support TFO.
Any plans to add this for Chrome on macOS, please? Is there an ETA available?
Any news on this?
TCP Fast Open in iOS 9 and OSX 10.11 seems permissible. Chris might be able to help us here.

I found to have given a Deck "Deploying TCP Fast 
Open in the wild"

Going to go ahead and close this - may be worth looking at, but we don't even enable Fast Open on Linux yet, despite supporting it.  We need to decide if it's worth the potential issues (Allowing tracking via Fast Open cookies, which certainly won't fly in incognito, at least, and potentially sending double-gets in the case of certain network errors)
