It does. I was thinking that since the "interim" mac, the one I am using right now, was on 10.6 I could just copy it to the one that came with Yosemite and be done with the whole thing. Those 10 hours I spent on the locked files were a bit of a bother.

On the PPC, I was using MacTex 2013 with  TeXShop 2.47 and, as I said, it just went over to the interim mac mini 10.6. Never saw it going.

That was the point: the software didn't, it was the hardware (although I haven't had the time to do the autopsy yet.)

I will, but for everything other than TeX, 10.5 to 10.6 was rather painful. I truly wish my PPC were still alive.

Of course, with Yosemite, everything will have to be fresh so it should be simple. 

Very grateful regards,
