I've read that OpenGL was deprecated in macOS Mojave 10.14 in the favour of Metal, Apple's proprietary low-level graphics API. Has it been completely removed in macOS Catalina? glxinfo
appears to be not installed.
OpenGL is still supported in the latest iMac - supported versions
If it has been removed, is there a way to install it?
glxinfo
is not a general OpenGL tool. It's specific to the X Window System, which is not the native windowing system of macOS. If you install XQuartz or X.org, it should come withglxinfo
.
