The new macOS Tahoe brings Liquid Glass but also new features like the Phone app
The new macOS went through five rounds of developer testing, beginning back on September 22, 2025. Perhaps the most significant or visible difference is that Apple has added a control to allow users to customize Liquid Glass.
The control is a toggle under System Settings, Appearance, which offers either Clear, or Tinted. It’s Tinted that offers the new option — turning it on prevents quite so much of the background being visible through Mac windows and menus.
