Apple’s macOS Tahoe 26 is the latest iteration of the renowned operating system for Mac users, offering a blend of enhanced performance, better security, and new features designed to improve your computing experience. If you’re eager to test the new features before the official release, joining the Apple Beta Software Program and installing the public beta might be the right move. This guide will provide a step-by-step tutorial on how to install the macOS Tahoe 26 Public Beta on your Mac.

Before proceeding, it’s important to note that beta software is not the final product and may contain bugs or issues that can affect your device’s performance. Therefore, it’s recommended that you install the beta on a secondary device or ensure that you have a complete backup of your data.

Prerequisites

Before you begin the installation process, ensure that your Mac meets the following requirements:

  • Compatible with macOS Tahoe 26 (check Apple’s official list of supported devices)
  • At least 20 GB of free storage space
  • Running a stable version of macOS (preferably the latest official release)
  • A stable internet connection for downloading the beta software

Create a Complete Backup

Before installing any beta software, it’s crucial to back up your Mac. This ensures that you can restore your system to its previous state if something goes wrong during the installation.

Use Time Machine for Backup

To create a backup with Time Machine, follow these steps:

  1. Connect an external storage device to your Mac.
  2. Open System Preferences and select Time Machine.
  3. Click “Select Backup Disk” and choose your external drive.
  4. Click “Use Disk” and wait for Time Machine to start the backup process.

Make sure the backup completes successfully before proceeding with the beta installation.
