When I first installed LyX, it could not find any layouts, and would produce "unknown textclass book" errors when opening the Tutorial, for example. This despite having done the Edit>Reconfigure step.
Using LyX>Preferences to set the path to the layouts I got the message "directory name can't contain any of these characters: space, '#', '~', '$' or '%'.
This explained the problem, cluing me to move LyX from where I had put it in
/Applications/$Document Apps/LyX
But that still didn't cure the problem, even when I used LyX>Preferences to set a new path to Layouts. Eventually I stumbled onto re-doing the Edit>Reconfigure step and relaunching; this solved the problem.
The following problems need to be addressed in the README (http://www.18james.com/lyx_on_aqua.html)
1) There should be an explicit warning against use of pathnames with $ or space. Such names are perfectly valid to Mac OS X users.
2) There should be an explicit warning that one must *rerun* Edit>Reconfigure whenever the LyX application is moved from one folder to another.
Thanks, Dave Cortesi
