I don't have two remotes, so can't fully confirm if it works properly or not, but there is a "pair" function. As can be seen in the image, it says "Unpair" under the option "Disable remote control IR receiver". This is because Ferd II must have one paired.
However, it normally says "Pair...". If you click that, it will tell you how to pair the remote. You can then pair which remote you want to your iMac.
The issue is, until you do that, it states under the option for disabling the IP receiver "This computer will work with any available remote.". Of course this isn't always ideal.
Then, on your Apple TV > Settings > General > Remotes, you can pair the remaining remotes.
To answer your question simply, it seems like yes, you can distinguish between remotes. 🙂
Like I said, can't say how well it works as I haven't got two remotes so haven't distinguished between them as such. But don't see why it shouldn't work like a charm! 🙂
Although I wouldn't have known about this if it wasn't for the genuis of Ferd II!! THANKS SO MUCH FERD II! 🙂 🙂🙂
This has been driving me crazy ever since I got my Apple TV and searching came up fruitless until now! 😁😁
(P.S. Awesome name PokémonFan! YAY FOR POKÉMON! 🙂)
