No MAC-OS Build Install option?

Currently I am running Windows 10, Unity 2108.1.4f1, and I cannot find the Mac OS build. When opening the correct installer for the 2108.1.4f1 build there was no option to select the Mac OS build support to install.How do I get this build support?119424-nomacbuildoninstaller.png

Are you trying to build for MacOS? The default unity build option (PC, Mac & Linux Standalone) does that.
