You didn’t mention the version numbers of any of your software components. For now I’ll assume it doesn’t matter. You have to make sure your TeX installation is found by LyX. 1st thing is to Reconfigure. If this does’t help check the contents of the PATH-Prefix in LyX-preferences. It should contain "/Library/TeX/texbin“ for newer MacTeX installations. If you don’t get further locate the protocol file of your attempt to reconfigure LyX. It is in your home folder in the hidden folder "Library/Application Support/LyX-2.2“ and is named „configure.log“. Please send the contents of this file to the mailing list. Stephan
