Question: On my Macbook Air (El Capitan) - 

Why is it that when I select `Open With>Other...` 

Enable `all applications`

check the checkbox `Always open with`

[![enter image description here](https://i.stack.imgur.com/4PQ6R.png)](https://i.stack.imgur.com/4PQ6R.png)

It still makes me do it all over again,... every time!!!

I am trying to open xml files with Chrome. But every time I select one from Finder and do open with... 

If I just choose `Open` then XCode opens it. 

What does the `Always open with` checkbox actually do? Is it for decoration only, and has no function? It doesn't do what I think it should. Please advise.

Answer: 
What you're doing is making Finder always open this *specific* *file* with Chrome. 

What you want is to open *all* XML files with Chrome. To do this:

1. Right click the XML file.
2. Choose Get Info
3. Under "Open with", select Chrome and then click "Change All..."
If you want to open all xml files in Chrome, you need to click the `Change All...` button in the `File | Get info` (cmd+i) window.
