Dear Yue and Taco, Thank you both for replying. Here are the fonts that I am trying to get from my source file (no problem using Minimals but when I use MacTeX installation that is when I get the problem). These are fonts for Irish Gaelic ancient and modern. Below is a snippet that I get from the Minimals output. But MacTeX tries to make Latin Modern instead of giving me the output below. This is not urgent since I can use Minimals but I would still like to put MacTeX right. I have since uninstalled all of my TeX including minimals. I have deleted all the Latin Modern Fonts and did a clean install of MacTeX . The problem is still there. Thanks again, Charlie Doherty
