Graphics Engine

To prepare for future Mac OS changes, AutoCAD 2021 for Mac uses a new graphics engine: Metal.

If you're running Mac OS 10.14 or 10.15, Metal is the default. You can switch back to the previous graphics engine, OpenGL, on the AutoCAD Preferences dialog box > General tab.

Note: Metal is not supported on Mac OS 10.13 or earlier.

Changed Commands
