Thank you all very much. This was a fun one to do and probably the quickest SU project I've had in a very long time.

Kim Frederik, That's a worthy comment to read and something to think about. Perhaps, if I can obtain a Thea for Max version, I will do exactly that for the future. I'm not in the position to invest more... but, that sounds great. Thank you. I know there is still a solution for this somehow... but, this sounds like a great band-aide. Peter, thanks for the intervention. Much appreciated.

Hello tomasz, I FINALLY figured it out! With the release of Lion, the User library is hidden by default. Type (or copy/paste) the following into terminal and your user library will no longer be hidden: chflags nohidden ~/Library/ Now unhidden, I found 'Thea4SU_files' & Thea4SU_loader.rb, I removed them, opened a previous version of SU 2013… IT WORKED. I updated to the last update and it's stable. Thank you. However, this problem was unique with the default settings of OS 10.7.5 on a Mac Pro. It's rare because it is the last OS version support on the MacPro, but not designed for this system. Actually, because SU 2013 does not support previous OS versions… and that the MacPro can't support any version of OS above 10.7.5… I got stuck in a crack that most would not be in. I am so pleased. Again, thank you.

For those faithful to Shaderlight… or, if anyone is already using Shaderlight and wanting to avoid paying 1/4th the price of the full version just to use it with SU 2014, the solution is making the models in SU 2014, then "downgrading" them (Save-as) to SU 2013 or SU 8 files and finally rendering in the identical SL 2013 (already paid for) plugin.
