How to Prepare & Get Ready for macOS Tahoe

Apple’s macOS Tahoe (macOS 26) is right around the corner, bringing powerful Apple Intelligence features, performance upgrades, and design refinements that will reshape the Mac experience. But before you jump in and hit “Install”, a little preparation can go a long way.

In this guide, we’ll walk you through everything you need to do to get your Mac ready for macOS Tahoe — from checking compatibility to ensuring a smooth installation.

1. Check macOS Tahoe compatibility

Not all Macs can run the latest system. Before anything else, confirm whether your machine supports macOS 26.

👉 See the full macOS 26, iOS 26, and iPadOS 26 compatibility guide for a detailed list of supported devices.

To check your Mac’s model and year:

• Click the Apple menu () > About This Mac.
• Note your Mac model and compare it with the supported list.

Keep in mind: older models may run Tahoe but won’t get all the AI-powered features.

2. Back up your Mac (the golden rule)

Before upgrading, back up your data. It’s the single most important step you can take.

• Time Machine: Apple’s built-in option is reliable and free.
• Cloud backup: Use iCloud, Dropbox, or Google Drive for essential files.
• Third-party tools: For more advanced backup, check out our Ultimate Guide to Mac Backup.

Skipping backups could mean losing files if something goes wrong — don’t risk it.

3. Free up space before installing

macOS upgrades require 20GB+ of free space for smooth installation. Running low? Time to declutter.

Options:

• Manually clear downloads, caches, and large files.
• Move photos or videos to external drives.
• Use a cleaner utility — we’ve tested several in our guide to the best Mac cleaner software.

This not only prevents install errors but also helps your Mac run better post-upgrade.

4. Update apps & drivers

Many apps release updates to ensure compatibility with new macOS versions.

• Update critical apps like Adobe, Microsoft Office, or Final Cut — and don’t forget popular Mac-first tools you rely on daily, such as CleanShot X, MacWhisper, or Alfred.
• Check external hardware (printers, audio devices, docks) for updated drivers.

Doing this ahead of time avoids frustration after the upgrade.

5. Ensure stable internet & power

The macOS Tahoe installer is a large download. Make sure you:

• Connect to a stable Wi-Fi network.
• Keep your MacBook plugged in to avoid interruptions.

6. Consider waiting for the first patch

As exciting as upgrades are, early versions sometimes come with bugs. If you rely on your Mac for critical work, consider waiting for macOS 26.1 or later.

If curiosity wins, install it on a secondary Mac to explore without risking your main machine.

7. Try the beta (optional)

Apple offers a Beta Software Program for those who want early access. But be warned: betas can be unstable.

If you’re interested, use a secondary partition or external drive instead of your main system.

8. Steps to install macOS Tahoe

Once you’re ready:

• Go to System Settings > General > Software Update.
• Download and install macOS Tahoe.

For a fresh start, consider a clean install (erasing your drive and starting from scratch). This often improves performance but requires restoring files from backup.

9. Post-installation checklist

After upgrading:

• Re-enable login/startup items.
• Review system preferences and privacy settings.
• Test your most-used apps.
• Restore any missing files from backup.

Bottom line

Upgrading to macOS Tahoe can be an exciting way to unlock new features and breathe new life into your Mac — but only if you prepare properly. By checking compatibility, backing up, clearing space, and updating apps ahead of time, you’ll ensure a smooth and stress-free transition.

With Apple Intelligence at the heart of macOS 26, this update promises to change how you work, create, and interact with your Mac.
