Microsoft Edge Legacy Virtual Machine doesn't start in VMWare Fusion 12 Pro I have just purchased VMware Fusion Pro 12.1.0 on MacOS Catalina 10.15.7.
I want to run a MS Edge Legacy virtual machine, available from Microsoft here:
https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
I have tried the virtual machines for Win10, Win8 and Win7. The problem seems identical or very similar with all.
I create the machine from the .ovf file in the downloadable zip, in Fusion Pro, via New &gt; Import an existing virtual machine. The .vmdk file included in the zip is grayed out and cannot be selected. Import of the .ovf seems to finish successfully according to the Wizard.
However, when attempting to Start Up the machine, nothing happens even when I wait a long time. First Fusion says &quot;Loading...&quot; for several minutes. After that, a black window opens with a &quot;Play&quot; icon. When I press it, I get the question: &quot;Would you like to upgrade this virtual machine?&quot;. I have tried pressing both &quot;Don't Upgrade&quot; and &quot;Upgrade&quot; with the same problems, so it doesn't appear to help.
Next, the virtual machine window stays black with a grayed-out &quot;Play&quot; icon. I wait and nothing happens. In the Fusion main window, I see the clickable option &quot;Clean Up Recommended&quot; immediately after attempting to start the machine.
Under the Menu option Virtual Machine, it says &quot;Windows is off&quot; and on the next row &quot;Starting Up&quot;. &quot;Restart&quot; and &quot;Shut Down&quot; are grayed out. The button &quot;Power On To Firmware&quot; is clickable but doesn't seem to do anything.
If I try to close the machine window or quit VMWare completely, it refuses to close the window and/or app, and says: &quot;The virtual machine &quot;MSEdge-Win-10-VMware&quot; is busy&quot;. After a very long time, an error message appears:

&quot;Failed to power on /path/MSEdge-Win10-VMware.vmx&quot;.

If I want to exit before this long wait, I have to Force Quit the application to get out. After restarting the application, I cannot Delete the virtual machine unless I've first deleted the newly created .vmwarevm file on the drive.
I previously used the Trial version of Fusion 11 with no problems on the same computer and virtual machines. Yet, Fusion 12 does not seem to work.
It appears the VMWare Fusion .dmg installation image file was put under the MacOS Quarantine, which made the application not function properly.
Uninstalling VMWare Fusion (I removed all files with AppCleaner), downloading the .dmg file again, and then running the following commands on the file, followed by running the installer solved the issue for me:
xattr -l ~/Downloads/VMware-Fusion-12.1.0-17195230.dmg
xattr -dr ~/Downloads/VMware-Fusion-12.1.0-17195230.dmg
