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[“http://www.feyncalc.org/install.m”] which fetches FeynCalc and FeynArts but I cannot use this FeynArts for some reason. I cannot load it in Mathematica 10 (Mac OSX).

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; <
