I'm beginner who is interested in learning Latex and I'm currently using Mac OS Catalina.
I decided to use Lyx for writing my lecture notes in Hebrew, so I'v downloaded Lyx. I managed to create files in english, but my problem was with Hebrew. After searching the internet, I realised that I have to install XeTex, I downloaded XeTex and unzipped it. In Lyx settings I changed the language to Hebrew and In fonts I checked the box that says: Use non-Tex fonts(via XeTex/LuaTex) as in the pictures bellow:
But I got Package fontspec Error again:
Seems that I have a problem with installing the fonts properly, I appreciate every help and even any suggestions for a different way to write Hebrew with Latex.
