Quote - For what it's worth....  I am not associating Carrara 8.5 with 'very buggy', so I don't know where that came from. 

Where it came from?

Maybe from all the people who can't find their runtimes, can't get Genesis to fit their clothes, can't get Autofit to work, and a hundred other problems.

I don't know about the Mac. I'm a PC user.

I guess if the software you have doesn't work on your new operating system, then you have to switch.
