Vimalin for Fusion 2.5 has been tested to work with VMware Fusion running on:

macOS Sierra, macOS High Sierra, macOS Mojave and macOS Catalina.

It probably works on earlier versions of OS X, but we haven’t tested that with Vimalin version 2.5.

Vimalin for Windows 2.0 has been tested and is supported on

Windows 7, Windows 8 and Windows 10, Windows 2008 R2, Windows Server 2012 and Windows Server 2016.
