VMWare Fusion VMon mismatch

27 Feb

Credit for the fix – https://www.tweaking4all.com/forum/applemac-hardware/macos-fix-vmware-fusion-version-mismatch-with-vmmon-module/

1. Close VMware Fusion
2. Open the Terminal and execute:

sudo rm -rf /System/Library/Extensions/vmmon.kext

sudo cp -pR /Applications/VMware\ Fusion.app/Contents/Library/kexts/vmmon.kext /System/Library/Extensions/

sudo kextutil /System/Library/Extensions/vmmon.kext

3. Exit Terminal and open Fusion again.

Now … you may run into an error message with the last command.
In that case you can try the following command, or like I had to do: reboot your Mac and try that last command again;

sudo kextunload /System/Library/Extensions/vmmon.kextd

Turns out the OST file 50GB limit was in play – the below resolved it perfectly
