What’s the Latest Version of macOS?
As of May 2026, the latest version of macOS is macOS Tahoe 26.5, released on May 11, 2026. This update follows macOS 26.4.1 (April 2026) and focuses on system improvements, security additions, and ecosystem‑wide changes rather than major new Mac‑exclusive features.
If your Mac is older and cannot run macOS Tahoe, you can still receive security updates for macOS Sequoia 15.7.7 or macOS Sonoma 14.8.7, both released on the same day for legacy devices. These updates contain important security patches and are recommended for all users who cannot upgrade to Tahoe.
Tahoe is notable because it is expected to be the final macOS version that supports Intel‑based Macs. Future major releases will likely require Apple Silicon.

Before You Update: Prepare Your Mac
Follow these steps before starting any macOS update. Skipping them can lead to failed installations or data loss.
Step 1: Back up your Mac with Time Machine
Use Time Machine to back up your entire system to an external drive. This allows you to restore your Mac to its previous state if something goes wrong. Go to System Settings > General > Time Machine to set up or run a backup.
Step 2: Check available storage space
macOS updates require significant free space. For a major update like macOS 26.5, you should have at least 20‑30 GB of free space. To check, go to Apple menu > About This Mac > More Info > Storage.
Step 3: Free up space if needed
- Empty the Trash.
- Delete large, unused apps (Finder > Applications > sort by size).
- Remove old iOS backups (System Settings > General > Storage > iOS Files).
- Move photos and videos to an external drive or cloud storage.
Step 4: Connect to power and stable Wi‑Fi
Ensure your Mac is plugged into a power source. Do not rely on battery power for a major update. Also, connect to a stable Wi‑Fi network – the update file is several gigabytes.
Step 5: Disable VPN and content filters
VPNs and security software (Little Snitch, antivirus) can block the update process. Temporarily disconnect any VPN (System Settings > VPN) and disable third‑party content filters.
For more on VPN issues, see our Mac VPN connection issues guide (cluster post #7).
How to Check for macOS Updates
There are two main ways to check for available updates. The graphical method works for most users; the Terminal method is for those who prefer the command line.
Method 1: System Settings (for all users)
- Click the Apple menu () in the top‑left corner of your screen.
- Select System Settings.
- Click General in the sidebar, then Software Update.
- Wait a few seconds for your Mac to check for updates.
- If an update is available, you will see it listed.
Method 2: Terminal (advanced users)
- Open Terminal (Applications > Utilities).
- Type:
softwareupdate -l - Press Return. This lists all available updates without installing them.
- To install all updates, type:
sudo softwareupdate -i -a - Enter your password when prompted.
For more Terminal commands, see our reset macOS network settings guide (cluster post #10).
How to Update macOS via System Settings
Once you have verified that an update is available, follow these steps to install it.
Step 1: Open Software Update
Apple menu > System Settings > General > Software Update.
Step 2: Select the update
You may see multiple options:
- macOS Tahoe 26.5 – the latest major version.
- macOS Sequoia 15.7.7 or Sonoma 14.8.7 – security updates for older Macs.
- Safari update or other minor updates.
Step 3: Click Update Now
Click Update Now next to the version you want to install. Your Mac may ask you to enter your password.
Step 4: Agree to the terms
Read and agree to Apple’s software license agreement.
Step 5: Wait for the download and installation
The download can take 10‑30 minutes depending on your internet speed. After downloading, your Mac will restart automatically. The installation may take another 20‑40 minutes. Do not interrupt the process.
Step 6: Log in and finish
After restarting, log in to your Mac. You may see a welcome screen or additional setup steps. Your Mac is now updated.
For help with sleep‑related issues after updating, see our Mac sleep settings guide (cluster post #9).
How to Download the Full macOS Installer
Some users prefer to download the full installer for a clean installation or to create a bootable USB drive. This is useful for upgrading multiple Macs or troubleshooting persistent issues.
Method 1: Download from the App Store
- Open the App Store on your Mac.
- Search for “macOS Tahoe 26.5”.
- Click Get or Download. The installer will be saved to your Applications folder.
Method 2: Use Terminal to download (advanced)
Open Terminal and type:softwareupdate --fetch-full-installer --full-installer-version 26.5
This downloads the full installer directly.
Method 3: Use direct download links
Apple provides direct download links for each macOS version on their official support site. Search for “Download macOS Tahoe” on Apple’s website to find the official links.
How to create a bootable USB installer
After downloading the installer, you can create a bootable USB drive using the Terminal command:sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSBDrive
Replace MyUSBDrive with the name of your USB drive.
For more on network diagnostics during installation, see our macOS network troubleshooting toolkit (this is a placeholder – you can create later).
What If Your Mac Is Too Old for the Latest macOS?
Not all Macs can run macOS Tahoe. Apple has dropped support for several older models. Here is the compatibility breakdown:
| macOS Version | Compatible Macs |
|---|---|
| macOS Tahoe 26.x (2025‑2026) | Macs from 2018 or later (some 2017 models excluded) |
| macOS Sequoia 15.x | Macs from 2017 or later |
| macOS Sonoma 14.x | Macs from 2017 or later (some 2017 models) |
| Older macOS versions | Check Apple’s official compatibility list |
Tahoe is expected to be the final version that supports Intel‑based Macs. Future major releases will require Apple Silicon (M1, M2, M3, M4, M5).
If your Mac is too old:
- You can still receive security updates for your current macOS version (e.g., Sequoia 15.7.7 or Sonoma 14.8.7).
- These updates are found in System Settings > General > Software Update under “Also Available.”
- If your Mac is stuck on an older version (e.g., Catalina or earlier), you may need to upgrade macOS version by version, not directly to Tahoe.
For older Intel Macs, see our Intel Mac SMC reset guide (cluster post #8) for power‑related issues.
Troubleshooting: macOS Update Stuck or Not Working
If your update seems frozen, stuck on “Checking for updates,” or fails to install, try these solutions.
Fix 1: Restart your Mac
This is the simplest and most effective fix. Shut down your Mac, wait 30 seconds, then turn it back on. Try the update again.
Fix 2: Check your internet connection
Run a speed test or try loading a website. A weak or intermittent connection can cause update failures. For signal help, see our Mac Wi‑Fi signal strength guide (cluster post #1).
Fix 3: Free up more storage
If you have less than 20 GB free, the update may not install. Delete unused files (see preparation steps).
Fix 4: Reset the Software Update preferences (Terminal)
Open Terminal and type:sudo rm -rf /Library/Preferences/com.apple.softwareupdate.plist
Then restart your Mac and check for updates again.
Fix 5: Kill the softwareupdated process
In Activity Monitor (Applications > Utilities), search for “softwareupdated” and force quit it. Then check for updates again.
Fix 6: Reset SMC (Intel Macs only)
For power‑related update failures, reset the SMC. See our Intel Mac SMC reset guide (cluster post #8).
Fix 7: Boot into Safe Mode and update
Restart your Mac and hold Shift (Intel) or press and hold Power then Shift (Apple Silicon). In Safe Mode, try the update. For Safe Mode instructions, see our how to use Mac Safe Mode guide (cluster post #4 from the Mac performance series).
Fix 8: Reinstall macOS from Recovery Mode
If all else fails, boot into Recovery Mode (Command+R on Intel, or hold Power for startup options on Apple Silicon). Choose Reinstall macOS. This will reinstall the latest compatible version without erasing your data. For a detailed walkthrough, see our macOS recovery mode guide (this is a placeholder – you can create later).
For broader network issues, see our Mac Wi‑Fi on no internet (cluster post #12).
Security Updates for Older Macs (Sequoia, Sonoma)
If you are not ready to upgrade to macOS Tahoe, Apple still provides critical security updates for older macOS versions. On May 11, 2026, Apple released:
- macOS Sequoia 15.7.7 – for Macs that cannot run Tahoe or users who prefer to stay on Sequoia.
- macOS Sonoma 14.8.7 – for Macs that cannot run Sequoia or Tahoe.
These updates contain only security patches, no new features. They are recommended for all users on those versions.
How to find them:
Go to System Settings > General > Software Update. Below the main “macOS Tahoe” banner, look for the “Also Available” section. Click More Info or Update Now next to your current macOS version.
Security fixes include:
- Vulnerabilities in APFS, Audio, CoreMedia, GPU Drivers, ImageIO, and other system components.
- Patches for issues that could allow apps to access private information, gain root privileges, or break out of sandboxes.

Frequently Asked Questions
Q: How often should I update macOS?
Immediately when security updates are released. For major version upgrades (e.g., 26.4 to 26.5), wait a few days to ensure no critical bugs are reported.
Q: Will updating macOS delete my files?
No. A standard update preserves your personal files, apps, and settings. However, you should always back up before updating as a precaution.
Q: Why is my Mac showing “No updates available” even though I know there is a new version?
Your Mac may be too old for the latest macOS. Check Apple’s compatibility list. Also, ensure you are not on a beta profile that restricts updates.
Q: Can I downgrade macOS after updating?
Downgrading is complicated and requires a Time Machine backup from before the update or a bootable USB installer. It is not recommended.
Q: My Mac updated, but now my Wi‑Fi is slow. What should I do?
See our Mac Wi‑Fi slow after update guide (cluster post #14). Also try resetting network configuration (cluster post #10) or checking your router settings.
Q: What is the difference between macOS Tahoe, Sequoia, and Sonoma?
Tahoe is the latest major version (26.x). Sequoia (15.x) is the previous major version. Sonoma (14.x) is the version before that. Apple releases security updates for the last two major versions for about two years after each new release.
