I download its files of both and still no working, Maybe because of the arnold version i guest. The Arnold version in my machine is Mtoa 2.0.1 Arnold core 5.0.1.0, and in the arnold render view no appear nothing. i'm recently new in arnold write color.

In maya 2018 what is the best way for working ai writeColor node?

You don't need aiwrite to split up diff and spec channels. simply add 'diffuse' and 'specular' aovs directly from render settings. also first tut is out dated, forget it. objectID just works. take a look at the attached file. eventually sometimes it may be good to stop and restart rendering to see your newly created aovs.
