macOS Tahoe Update Not Showing Up? Try These 6 Fixes

Apple has officially released macOS Tahoe (macOS 26), a major update for Mac users. Many are excited about the new “Liquid Glass” design and improved performance, but not everyone sees the update right away in System Settings. If macOS Tahoe isn’t showing up on your Mac, you’re not alone. Many users have reported the same issue — the update simply doesn’t appear.

In this guide, you’ll learn why your Mac isn’t showing macOS Tahoe, the most common causes behind it, and how to fix it for good.

Why Isn’t macOS Tahoe Update Showing on My Mac?

There are several reasons why macOS Tahoe might not appear or be available in Software Update. Common ones include:

• Your Mac isn’t compatible with macOS Tahoe.
• Apple’s update servers are temporarily busy or down.
• Your internet connection is unstable.
• System cache or macOS bugs are interfering with the update.
• Your Mac doesn’t have enough free disk space to download macOS 26.

The last point — not enough storage — is one of the most overlooked causes. Many users don’t realize that macOS updates can require 15 GB or more of free space to download and install properly. If your Mac is nearly full, the update might not appear at all.

Don’t worry, let’s walk through how to fix that!

macOS Tahoe Update Not Showing Up? 6 Proven Fixes

If the macOS Tahoe update isn’t showing in Software Update, try these steps. These methods have helped many users successfully install the new macOS.

1. Check Your Internet Connection

It may sound simple, but a stable internet connection is essential. Without it, your Mac can’t reach Apple’s update servers.

Go to System Settings > Network and make sure you’re connected to a working Wi-Fi network. You can also try:

• Turning Wi-Fi off and back on.
• Switching to a different network.
• Forgetting and reconnecting to your current network.
• Restarting your router or using a mobile hotspot temporarily.

2. Make Sure Your Mac Is Compatible

Not all older Macs support macOS Tahoe. Apple regularly drops support for outdated models to maintain system performance and security. Check if your model is listed on Apple’s official macOS Tahoe compatibility list.

If your Mac is too old, macOS Tahoe won’t appear in Software Update. In that case, you may still be able to install it with OpenCore Legacy Patcher 3.0.0, which is expected this winter.

3. Free Up Disk Space on Your Mac

As mentioned earlier, a lack of free space is one of the most common reasons macOS Tahoe doesn’t appear or install properly. You’ll typically need at least 15 GB of free space for the update.

This is where BuhoCleaner can make things easy. BuhoCleaner is a professional Mac cleaning and optimization tool designed to safely free up space in seconds. With just a few clicks, you can:

• Remove system caches, logs, and temporary files.
• Delete large DMG installers and old Xcode data.
• Find and remove duplicate files.
• Analyze your disk usage in real time.

That means more space for macOS Tahoe without wasting time hunting for files manually.

4. Check Apple’s System Status

When a macOS version launches, millions of users try updating at the same time. This can overload Apple’s update servers.

If none of the methods above work, visit the Apple System Status page to check whether macOS update services are temporarily down.

5. Restart Your Mac or Boot in Safe Mode

A simple restart can work wonders. It clears temporary files and stops background processes that might block updates.

If that doesn’t help, try booting into Safe Mode:

1. Shut down your Mac.
2. Hold the Shift key while turning it back on.
3. Release the key when the Apple logo appears.

Safe Mode only loads essential system components, making it easier to detect issues that may be preventing macOS Tahoe from appearing.

6. Search for macOS 26 Using Terminal

If you still don’t see macOS Tahoe in Software Update, you can manually look for it using Terminal. This method only works if Apple has officially released the update and your Mac is compatible.

Here’s how:

1. Open Terminal via Spotlight or Finder > Applications > Utilities.

2. Enter this command:

   softwareupdate --fetch-full-installer --full-installer-version 26.0.1

3. Wait for the scan to complete and follow the on-screen instructions to install macOS Tahoe 26.0.1.

Conclusion

If macOS Tahoe isn’t showing up on your Mac, the issue is usually related to a poor internet connection, compatibility limitations, or insufficient storage space.

Before you panic, try the steps above, especially freeing up space with BuhoCleaner. It’s the easiest and safest way to prepare your Mac for the update.
