Whether you’re upgrading from a previous macOS version or doing a clean install, this guide will take you through every step to ensure a smooth installation process.
Before starting the installation, ensure your Mac meets the minimum requirements:
- Mac Model Compatibility:
- MacBook (Early 2016 and later)
- MacBook Air (Mid 2017 and later)

Before proceeding with any major OS upgrade, it’s crucial to back up your Mac. You can do this in two main ways:
1. Time Machine Backup:

1. Open the Mac App Store.
2. Search for macOS 15 Sequoia in the search bar.
3. Once found, click Get to download the installer.
From System Settings:
1. Click the Apple menu in the top-left corner of the screen.
2. Select System Settings > General > Software Update.
3. You should see macOS 15 Sequoia as an available update. Click Upgrade Now.
Once the installer is downloaded, it will automatically open. If it doesn't, locate the installer file in your Applications folder and double-click it.
1. Follow the on-screen prompts. Click Continue on the welcome screen.
2. Agree to the terms and conditions after reviewing them.
3. Choose the drive where you want to install macOS 15. For most users, this will be the Macintosh HD.
4. Click Install and enter your admin password to begin.
macOS 15 Sequoia will now begin installing on your Mac. During the installation:
- Don’t turn off or restart your Mac.
- Your Mac will restart several times throughout the process.
- Depending on your Mac’s speed, this step may take 30 to 60 minutes.
After the installation, your Mac will boot into macOS 15 Sequoia. Follow these steps to complete the setup:
1. Sign in with your Apple ID.
2. Set up iCloud, Apple Pay, and Siri if necessary.
3. Review System Settings and ensure everything is configured to your preference.
If you performed a clean install or used Time Machine for backup, you might need to restore your files:
1. During the setup process, you’ll be prompted to use Migration Assistant.
2. Select your Time Machine backup or another source, and choose the files and apps you want to restore.
Once the installation is complete, update all your apps to ensure compatibility with macOS 15 Sequoia. You can do this through the App Store or directly through each app’s website.
If the installation process seems stuck, try these steps:
- Wait: Sometimes the installation can take longer than expected. Wait up to an hour before trying anything else.
- Restart your Mac: Hold the power button to force restart, then try installing again.
- Re-download the installer: Corrupt downloads can cause issues. Delete the existing installer, re-download from the App Store, and try again.
If macOS 15 Sequoia can’t be installed due to insufficient space, try these:
- Clear Disk Space: Delete large files, empty the trash, and uninstall unused apps.
- External Drive Installation: Install macOS 15 on an external drive temporarily and free up space later.
If your Mac won’t boot after installing macOS 15:
1. Start in Safe Mode by holding Shift during startup.
2. If that doesn’t work, try Recovery Mode by holding Command + R and reinstalling the OS.
After upgrading, explore some of macOS 15’s exciting new features:
1. Dynamic Desktop Improvements: Enhanced animations that change based on the time of day.
2. System-wide Adaptive Sound: macOS adjusts system sounds dynamically based on your environment.
3. Safari Overhaul: A redesigned tab grouping system with better cross-device sync.
