Right, administrator privileges are indeed easier this way. I suppose
an applescript could easily execute shell scripts with administrator
privileges as well. But it works, that's all that matters!

Right, so in that sense it would probably be a not bad idea if
TextMate prompts the user to set this link for them from /usr/local/
texprograms to their current tex install?

Hadn't actually read those threads before, looking at them now. But
if I understand them correctly, is there really any harm done by
setting the PATH variable there to be:
along with setting /usr/local/texprograms to link to the appropriate
I agree with some of the points there, that individual applications
should set their own preferences. But in this case I don't thing we
are talking about the setting of one particular application. We are
talking about the settings of the TeX installation, which a number of
applications need to have access to. So we need to set the indicator
of the current TeX install in a way that all apps needing it can
access it. If this is not done in environment.plist, I suppose the
only other option is to agree to use something like /usr/local/
The alternative is really requiring the user to set this path in
every single app needing to use LaTeX, which I don't think is really
I personally like the idea of just relying on /usr/local/texprograms,
and having TM prompt to set it for the user if it is not already set.
Don't know if there are any possible problems of that though.
