As the attached shows, Tex Text stops work on my mac now. I haven't used it for a while, but it did work before. Several weeks ago, I updated my system to OS X EI Capitan, and just found Tex Text doesn't work.Do you guys know what's going wrong here?

Thanks

I can't help with the traceback. But I have answered a few messages from people who lost their TexText or LaTex extensions entirely. I still haven't found out why. For them, I suggested simply reinstalling it. But in your case, I suppose it could be about the Mac update. It probably wouldn't hurt to try reinstalling the extension.

But maybe someone who understands the traceback will be able to tell you more.

Unfortunately, the traceback is cut off where it gets interesting. Could you post the second half, too?
