Upgraded from Mojave to Catalina: Now VMF won't run

[steveroberts1]

Hi Folks, Been a long day... I've finally upgraded from Mac OS14 to MacOS 15, Catalina. Having some trouble getting VMF 11.5.7 up and running. The app launches, but then I get a dialog box: "Cound not open /dev/vmmon: Broken pipe. Please make sure tha tthe kernel module "vmmon" is loaded. Followed by: "Failed to initialize monitor device" Then: "Transport (VMDB) error -14: Pipe connection has been broken. Thanks in advance for any assistance in resolving this issue. SR

Can you please provide both the macOS version (from About this Mac) and the Mac model that you are using. 

Have you tried a full uninstall of Fusion per KB article https://kb.vmware.com/s/article/1017838, then reboot your Mac, then reinstall Fusion.
