This is actuality pretty weird because yesterday I was able to recreate it a few times. On my Mac I have tried OMP_NUM_THREADS = 8 and 4 and for both settings I get the same tracks.

Red line is from MacBook - it's still different than Bill's tracks and I don't believe that it's real. My first concern is the weird loop after depletion of central helium and the second one - I don't see a reason why luminosity drops so low after helium depletion. It looks rather unreal, but I can't get other track on my laptop today!

As you can see this is different than my Mac's result and more similar to Bill's track. And it looks better (but this might not be true of course…).
