Apple’s latest macOS update, macOS Tahoe, introduces a striking new Liquid Glass interface and several productivity-enhancing features. While it’s currently in beta, you can access it now. Here’s a full guide on how to install the macOS Tahoe Developer Beta, along with what to know before you do.
Why Install macOS Tahoe?
macOS Tahoe, also known as macOS 26, brings several powerful additions:
