Upgrading your OS with everything it includes should improve the device’s overall performance, solve various operating bugs, and so on.

It often happens toVMware Fusionusers who upgrade the macOS version or just the virtual machine version. On rare occasions, it has also been reported by Windows users.
After upgrading, the users are not able to open thevirtual machine(or install new machines) and get the following message:Cannot find a valid peer process to connect to.
