.MENU File

The SystemUIServer is a background process that controls several aspects of the Mac OS X (macOS) user interface, and is one of the applications that are constantly running, when viewed with the Activity Monitor.

Specifically, it controls the right hand side of the Menu bar, where the Menu Extras live, as well as handling application launch following CD or DVD insertion, and handling external devices, such as the iPod.

A bad hardware state may cause the SystemUIServer to hang. Often, unplugging the external device will unhang the SystemUIServer.

The SystemUIServer is owned by the logged in user (as opposed to root) and automatically restarts if it crashes or is force quit.

A menu file extension is related to the macOS (OS X) operating system for Apple Mac computers. A .menu file stores plugin.

How to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .menu file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
