The Mac (universal) binary can be found here: <http://edisk.fandm.edu/bennett.helm/LyX/LyX-1.5.0rc1-Mac.dmg>
Bennett, I get an error: AppleScript ErrorFinder got an error: Can't make file "Macintosh HD:Users:anek:Library:Fonts:lyx-math" into type reference. (-1700)
It comes directly after I click Install when running the LyX- installer from the disc image.
No console messages. I have no lyx-math in ~/Library/Fonts/ (or in /Library/Fonts/). Anders
