I finally purchased a new MacBook Pro with TouchBar. But I found that Karabiner still doesn't work on macOS Sierra...
OMG... OMG... No, No, NO NO NO!!!
How can I be productive enough without the amazing software?
It is definitely the kind of things I could never tolerate in my working environment; it is the single most important app I have ever used on OS X...
So I will likely end up with a refund. Thanks Apple for its generous customer experience.
Ah, and iPhone 7 Red is cool๐
