When first installing VMWare fusion on your mac you may find that your initial installations fail. You will have the ISO or image file installed and linked correctly but on start up the guest will appear to fail to start. Lots of broken pipe errors and which after acknowledging your new VM guest will simply fail. If this sounds like your problem check and make sure the issue is not your Mac preventing the install based on security settings.
Open your system preferences, which you can find using the apple command button and space bar to bring up search. Enter “System Preferences” and click on the icon when it shows
Once you have the system preference menu open search for “Security and Privacy”
Once this opens click on the “General” tab and if you see a message towards the bottom about applications from VMWare not being trusted, unlock the menu by clicking on the padlock and then accept updates from VMWare.
Finally return to VMWare and restart your guest and hopefully all is well now.
