Research direction
Start with the BugSplat call stack and inspect llimagegl.cpp at lines 1475 and 1691, then follow LLGLTexture::createGLTexture in llgltexture.cpp and the media update path in llviewermedia.cpp. Determine the cause of the macOS GPU crash during media texture creation; done means the reported crash path is addressed and the relevant behavior is verified.
