[OS X TeX] Mactex and PowerPC processors

Thanks for the information, which is news to me, particularly since nobody from 2013 on has
complained about this.

I actually compile that code on a PowerPC machine. Maybe either I or you have non-standard X11.

The main reason I still distribute the package is that users with old machines will otherwise
lose support for tlmgr and thus have to manually update packages. On the other hand,
several people including contributors to MacTeX would like to see PowerPC code vanish.

This is probably a change for next year.

But VERY useful report. You could be the only one who has tried to run
this code, since I’ll confess that I installed it and checked it on Leopard Intel,
but not on Leopard PPC.

Dvips crashed immediately with a segmentation fault and xdvi immediately quit, complaining that the libX11 library did not have the appropriate code. I didn’t do any further testing with mactex 2016 but I did go back to previous versions of mactex and had the same crashes with the 2013, 2014, and 2015 mactex distributions. I didn’t go back further than 2013.

I think the last Macs with PowerPC processors were built in 2006
