I upgraded my vmware fusion and found that all my NAT networking connections stopped working.After much googling and poking around I couldnt find any answers. I found my Bridge networking was working fine, so how to fix NAT? Well after kicking the vmware networking on MAC with:

sudo /Library/Application\ Support/VMware\ Fusion/boot.sh --restart

I saw lots of permission errors and repair messages on the first run. Once I ran it again I still got the following error in the traceback:

Permissions differ on "Library/Application Support/VMware Fusion/VMDKMounter.app/Contents/MacOS/vmware-vmdkMounter", should be -rwxr-xr-x , they are -rwsr-xr-x .
Warning: SUID file 'Library/Application Support/VMware Fusion/VMDKMounter.app/Contents/MacOS/vmware-vmdkMounter' has been modified and will not be repaired.

So to fix I simply changed the permissions to be as they should be!

sudo chmod 755 "/Library/Application Support/VMware Fusion/VMDKMounter.app/Contents/MacOS/vmware-vmdkMounter"
sudo /Library/Application\ Support/VMware\ Fusion/boot.sh --restart

That came up with no errors, so I just restarted networking on my vmwares and volia! All fixed!On my ubuntu vm's I had to remove my networking rules and restart - like so:

sudo rm /etc/udev/rules.d/70-persistent-net.rules
sudo reboot
