I recently got a new mac and was migrating a VMWare Windows Virtual Machine from my other computer. When starting the virtual machine, I received a random message from VMWare Fusion saying “Cannot find a valid peer process to connect to.”

The fix was rather simple as it was just Apple blocking VMWare from running. To fix it, follow these steps:

1. Open System Preferences by searching in Spotlight or clicking the gear icon in the dock.
2. On the top row there is an icon for Security and Privacy – Click that icon
3. Near the bottom of the screen that appears the following statement
   “System software from developer “VMWare, Inc.” was blocked from loading”
4. Click Allow
