Lost vm bar in one of the VM

[melmore]

I have four different windows OS

I lost the capaibility to go make to Host system in one of them. (no vm bar to minimize) must shutdown to get back control of VM

Any ideas?

Copy and paste the following command, as in, in a Terminal and then press Enter.

defaults delete ~/Library/Preferences/com.vmware.fusion fullScreenTitleBarShow

This will clear the setting to its installed default and be visible again.

under the command prompt ?

I said "Terminal" not "command prompt"!

Type Terminal in Spotlight or navigate to: /Applications/Utilities/Terminal

Open a Terminal then copy and past the full command line as is and then press Enter and the prompt should return without any output.  The command removes the fullScreenTitleBarShow key from the /Users/${USER}/Library/Preferences/com.vmware.fusion.plist file which is not present in a default install thus removing the setting that's hiding the Fullscreen Title Bar.

Note:  There are other way to resolve the issue, by selectively editing the .plist file (if you know what you're doing) or with the Virtual Machine Library open you should be able to toggle between the Virtual Machine window and the Virtual Machine Library window and then toggle the state of the Fullscreen Title Bar.
