How to install and use FeynArts?

I want to be able to use both FeynCalc and FeynArts (together seems impossible, I’m fine with using them separately for now). I don’t know how to install FeynArts and run the simplest examples. I tried Import[“”] which fetches FeynCalc and FeynArts but I cannot use this FeynArts for some reason. I cannot load it in Mathematica 10 (Mac OSX).

When I follow this site’s suggestion

A dialog asking if you want to patch FeynArts will appear. Type yes
and hit OK. Wait until the patching process finishes

This dialoge never appears in my case, but only an error message saying:

$LoadPhi = True; $LoadFeynArts = True; < True] Finally if you want to patch FeynArts write the following $LoadFeynArts = True; followed by <1];
