OS X Studio Crash on Startup, Log File Location, CUDA

TheGlennK

Hi all, wanted to share this so maybe I can save someone else's sanity and all of their work customizing Studio. This is NOT about CMS.

OSX installation of Studio, has worked for years. No changes made to the system aside from normal OS and Studio updates. Studio began crashing on app startup, last visible message on the DAZ is Conencted to CMS. No errors from Studio, only the Apple crash report. 

Fix: Download and install the latest CUDA drivres for OSX from Nvidia. http://www.nvidia.com/object/mac-driver-archive.html or search for Nvidia OSX CUDA archive

In the log file was this wonderfuly helpful message. Hey, DAZ, MAKE THIS A FREAKING VISIBLE ERROR MESSAGE!

2017-06-08 18:59:35.399 WARNING: /src/pluginsource/DzIrayRender/dzneuraymgr.cpp(307): Iray WARNING - module:category(CUDA:RENDER):   0.0   CUDA   rend warn : The version of your CUDA driver is 7.5, but 8.0 is the required minimum​

DAZ, let's spend a little less time on CMS and maybe go back to basics: error handling. User story, add it to your backlog.

For those people like me, who couldn't find the log file until AFTER blowing away everything on my system with the word DAZ in it, the location of the Studio log file is: ~/Library/Application Support/DAZ 3D/Studio4

Cheers and Happy Rendering!
