I tried to install packages: FeyArts, FormCalc, and LoopTools in Mathematica 10 under Mac OS 10.11.3 system. I installed them separately in the directory /user/local and recall them in Mathematica Notebook by


Both FeyArts and FormCalc worked very well, but LoopTools returned following massage:

LinkOpen::linke: \!\(\*RowBox[{"\"Could not find MathLink executable\""}]\). >>

Then I used automatic installation script FeynInstall and install these packages into other directories and recall them again, but nothing changed.

I also noticed, there are Ready-made MathLink executables for Mac OS X below LoopTools website, but not sure if these files could solve my problem.

Is there anyone who can give me some suggestion?

    $\begingroup$ Why don't you simply contact Thomas Hahn directly? He is a very friendly person and also uses a Mac, so I guess that this would be the fastest and simplest way to resolve your problem. $\endgroup$ – vsht Feb 29 '16 at 10:40
