(Apologies if this is a duplicate; the first version didn’t seem to make it.)

Hi Dick, first off, thanks as always for all the work you do on MacTeX. It’s clear that TL 2015 is now perfectly prepared for El Capitan and its prohibition on writing to /usr directly. Do you know what will happen to users who have pre-TL 2015 systems but who upgrade to El Capitan?

I can see two possibilities: 

A. everything that used to work still works, because /usr is not touched
B.  older distributions will fail to work at all because /usr/texbin isn’t there anymore after the upgrade

Obviously if the answer is A, then there’s no potential problems for older distributions on newer OS.

But if the answer is B, is there a simple solution to allow users with older distributions to keep using those distributions with the new link?  

If it’s just a matter of making a new link, a clickable script might help a lot of the more Terminal-phobic folk.
