Starting with version 4.4, Macaos Enterprise makes use of OpenGL 3D graphics rendering routines in the Mechanical Part viewer.
Some users have reported that they encounter a system error when starting Macaos Enterprise, after having upgraded from a version prior to 4.4. Usually, a log file is generated which refers to the graphics driver and an error which arose within the OpenGL rendering system.
In all cases that we are aware of, this problem is resolved by updating the graphics driver to the latest version.
