macOS - Fix VMWare Fusion: Version mismatch with vmmon module
October 19, 2019 11:46 PM
So this is what I can into today ... upgraded to Fusion 11.5 and got the message that the vmmon module was the wrong version.
This appears to be a kext issue.
The solution I found, remove the kext and copy the kext from the VMWare Fusion application as a replacement:
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.kext
