I installed yesterday Feyncalc for the first time directly in Mathematica using the instructions given in the FeynCalc page

Import[“https://raw.githubusercontent.com/FeynCalc/feyncalc/master/install.m”]; InstallFeynCalc[]

I was working perfectly all day. Today I want to start working with the same Dirac.nb program and it does not find FeynCalc.

I am using MacOS Sierra 10.12.2

I have tried to look for the path of FeynCalc, without success, even I installed the program in the FeynCalc directory in the applications and it still did not work.

Any help?
