[OS X TeX] MacTeX 2014 TeX Distribution panel broken under Mac OSX Yosemite RC

I'm traveling and won't be back to deal with things for three or four days.
Let me add just a little to Herb's reply.

1) I installed previous betas of Yosemite on a fresh partition and used MacTeX to install
TeX. That worked fine.

Unfortunately, I didn't try the update route, with MacTeX already installed. You report a one hour
delay installing this way. Our other user reported a 12 hour delay. Clearly we need to investigate,
and probably warn users that it is easier to uninstall TeX Live, update, and then do a clean install of

2) The author of the TeX Dist Pref Pane is aware of a problem, but I don't know whether
he is working on a solution.

However, I constructed a similar Pref Pane, which you can get at


This zip gives you a pref pane, a pdf explaining it, and full source. This pane doesn't
change any data used by the original pane, and can be used in conjunction with it or
instead of it. The one disadvantage is that it puts uses as symbolic link to the binaries


Thus the disadvantage is that you must reconfigure your GUI apps, but the advantages are

	a) Apple sometimes removes /usr/texbin, but doesn't remove items in ~/Library

	b) This location is user writeable, so users can have independent default TeX

PS: Did you already have the MacTeX install package, or did you download it again. I ask
because Apple has changed signing methods and I haven't yet tested if our packages needs
to be resigned.

My son had no issues and it gave us access to some iCloud features that were rolled out on our iPhones and iPads, so I gave it a try. I ran into a couple of MacTeX 2014 issues (and found workarounds) that I thought I should report since the Yosemite release is scheduled soon (Oct 16 IIRC).

I should that the OS upgrade hung for well over an hour at the 2 min left point. Turns out it was copying files from /usr/local (TexLive and homebrew) from a recovery partition back to /usr/local. Cmd-L  lets you see this in the log. I mention this because I suspect those of you who do upgrade installs will likely encounter this and might be concerned (as I was)...

It turns out that this Yosemite beta/RC has a known problem passing environment variables to processes. The apps never read the bash environment from .profile but one used to be able to use a csh syntax and set environment variables in /etc/lauchd.conf that many apps read/find. This does not now work for RStudio or another application (ImageJ) that I use. I did find a workaround - I can set the path and environment variables directly via launchctl from a bash shell script. Here are a couple of lines from the script in case it helps someone
