Hello,
I just installed the latest OS on my mac, but one of the apps that I use frequently stoped woking - TeXShop. How do I bring it back to life? It doesn let me change or edit mt files anymore.
Latex on el capitan.
You could try the new version of mactex 2015 released a few days ago. It includes texshop.
It is meant for yosemite so I'm not sure if it will work with el capitan.
You can get it here for free: https://tug.org/mactex/

Anton, you scared me there :-)
Same here. Now, I do remember that TeXLive puts lots of stuff in /usr/texbin. That had caught me with a massive update time going to Yosemite. I think what I did at the time was moving that out of the way. Anyway. I checked again, and saw that my symlink there was missing. So, having deactivated rootless, I did this:
cd /usr
sudo ln -s ../Library/TeX/Distributions/Programs/texbin
That's it, all working again. Except, well, Skim, which is another story.
Also, as a side note, I saw that my symlinks in /usr pointing to /opt/X11 were missing. So, again in /usr,
sudo ln -s /opt/X11 X11
sudo ln -s /opt/X11 X11R6
Thanks for the heads up.
The more robust solution going forward is to rather change the path settings in TeXShop to /Library/TeX/texbin instead of /usr/texbin. That symlink is created by the latest MacTeX installation.
The problem is that even after giving an administrators password, the operation is not permitted.
This is because of the "rootless" feature in El Capitan. Basically, it prevents any process from creating files in /usr (other than /usr/local), as well as other directories. The easiest way I found to create the symlinks is to boot into single user mode, and create them there.
