Thanks Technogeezer. I got the Fusion 13.5.2 installed and a MacOS 10.11 virtual machine works, but the 10.14 Mojave machine comes up with this "Failed To Power on" error. Two other virtual machines "can not be found", even though they are in the same spot. I tried adding them but the "+" function doesn't seem to work. Any clues on these issues please?
UPDATE> Mojave issue solved. You need to click the Spanner top right and downgrade the machine from Hardware 21 to Hardware 19 and away it goes. Then I had to install the Toolkit. Still working on the "Not Found" issue. I think it is only looking on a drive that no longer exists, but there seems no way to change that.
UPDATE 2> You can not change the mapping but you can use Finder to go to the virtual machine and double click it. It then opens. I did not upgrade the virtual machine when asked if I wanted to. When asked if it was moved or copied I did "Moved". Then you need to reinstall VMware Tools. It adds the VM to the list in the Library so just delete the old one. All working. Thanks all.
