uBar is an application designed for Mac users transitioning from Windows, providing a customizable taskbar experience that allows for better management of applications and windows compared to the traditional macOS dock. It presents each window separately, offers extensive customization options, includes a Windows-style Start menu for easy access to folders and applications, and features additional elements like a clock and volume indicator. However, users have reported issues such as the Finder app appearing on the taskbar despite settings to hide inactive applications, misaligned menu options when right-clicking, and closed windows remaining visible on the taskbar. A free trial is available for users interested in exploring uBar's capabilities.
