Workaround: To successfully unmount the disk, Use Force Quit to close the Finder and then use Force Eject to unmount the DMG file. The error wrongly indicates that the Finder is still using the file. If you use macOS Big Sur 11.5 or later as the host, when you try to eject the mounted Fusion DMG file, it fails with an error. Cannot unmount Fusion DMG file mounted on the host macOS Big Sur 11.5 or later.Note that this is a user interface issue and does not impact the guest OS functionality.

When you install VMware Tools with Big Sur as the guest OS, the version of the guest macOS in the VM description changes from 11.x to 10.16.

VM description shows an incorrect version for the guest macOS Big Sur.

If the Big Sur host is connected to VPN, then the VM cannot access the same network as that of the host.

The virtual machine (VM) cannot access the same network as the host while macOS Big Sur host is connected to the virtual private network (VPN).

MTU configuration option is not available in the Fusion UI on Big Sur hosts.

Jumbo Frame can't be enabled for NAT virtual machines and Host-only virtual networks on Big Sur hosts.

On Big Sur hosts, if a user configures NAT port forwarding in Fusion, the service running in the virtual machine is unavailable on the macOS host using localhost:exposedPort, hostIP:exposedPort, or 127.0.0.1:exposedPort Port forwarding is also not accessible inside a NAT virtual machine using hostIP:exposedPort.

Unable to access port forwarding on a NAT virtual machine if the traffic is routed through the host IP stack on Big Sur hosts.
