Subject : BCC AVX crashes Avid on launch with Segmentation Fault error
Issue : When launching Avid Media Composer after installing BCC AVX, Avid crashes with the following error:
error while trying to \Initialize AVX2 Host\ pop up appears and reads: \Segmentation faut\ in thread \MainThread\, at address 0x0
Cause : This would be due to BCC attempting to load a hardware asset that is no longer present -- the most common reason would be if CUDA-based hardware was removed from the system, but the drivers for this hardware were not uninstalled.
Steps to work around the issue:
- With all possible programs closed, delete the file called “libcudart.dylib” from this location -Macintosh HD :: Library :: Application Support :: BorisFX :: Lib :: BCC9BitDepthSupport*
- - If Avid crashes, search for these following files, and if you find them, delete them as well -Macintosh HD :: System :: Library :: Extensions -- Filename: ʻCUDAʼ (if folder, delete)
Macintosh HD :: System :: Library :: StartupItems -- Filename: ʻCUDAʼ (if folder, delete)
Macintosh HD :: Library :: Frameworks -- Filename: “CUDA.framework”
Macintosh HD :: Library :: PreferencePanes -- Filename: “CUDA Preferences.prefPane
Macintosh HD :: Library :: LaunchAgents -- Filename: “com.nvidia.CUDASoftwareUpdate.plist”
- Once these files have been removed, Restart the Macintosh and try re-launching Avid Media Composer.
