I have installed MacTeX 2016 in a MacBookPro (OS 10.10.5), and I cannot "LaTeX", in TexShop a TeX-file containing cyrillic characters in the text.

My preamble:


And this is what I get:

enter image description here

EDIT. It works though with sudo latex in an xterm. Hence, it has to do with permissions.

Any suggestions?

  • Your installation is broken: the mkdir command is trying to use a wrong path. – egreg May 15 '17 at 9:06
  • @egreg What should I do? – Yiorgos S. Smyrlis May 15 '17 at 9:08
  • I've never seen anything like that. It seems some environment variable is set which shouldn't be. – egreg May 15 '17 at 9:14
  • @egreg Actually, I run in an xterm the command "sudo latex filename.tex" and it worked - Apparently, my Mac does not allow modifications of the installation of MacTeX – Yiorgos S. Smyrlis May 15 '17 at 9:18
  • Hmm, you have misused sudo, it appears. Check the permissions in /Users/yiorgos/Library: everything in it should be accessible to the user. – egreg May 15 '17 at 9:22

You have apparently played with sudo in improper ways. The MacTeX version of TeX Live stores generated files on a user basis in


and subdirectories thereof. These should have full access by the user, of course.

A simple strategy for resetting the ownership of the directories and files to the user is

sudo chown -R <user> /Users/<user>/Library/texlive

Change <user> into your name as shown by whoami, hit Return and all should be well.

A good general method on Unix systems to see what's the involved directory is to issue

kpsewhich -var-value=TEXMFVAR

On a standard TeX Live this might return


(with <year> corresponding to the currently installed and active distribution). With MacTeX it returns


but running the chown command on the top level is probably better in order to reshape everything to normal.

Other Unix flavors of TeX Live might use
