Yes, I meant the LyX upgrade. If one does the "install" of a new version one only copies the contents from the disk image to the current programs folder (this is /Applications on Mac OS X). LyX compares the timestamp of it's executable and the lyxrc file on start and runs configure.py if the executable is the newer one or lyxrc is missing. If you've updated e.g. from 2.1.3 to 2.1.4 the lyxrc should be there and the preferences are read and possibly migrated by LyX's scripts. If you're running 2.2.x the first time a copy of the 2.1 preferences is made by configure.py (only on the Mac platform because of complaints of some Linux developers) and the migration is done on the fresh copy of course. ATM, there is no mechanism to adjust parts of the PATH environment the user has in the preferences by configure.py. > > So if someone does a fresh installation of LyX 2.2.0dev on El Capitan > there should be no problem? Yes, this should be true for both 2.1.4 and 2.2.0. The lyxrc.dist.in of 2.1.4 already contains the directory "/Library/TeX/texbin" in PATH. The TeX distribution should be found and usable by LyX this way. Stephan
