Keeping your macOS updated is crucial for security, performance, and access to the latest features. If you’re still using macOS High Sierra and looking to update, this guide will walk you through the process step-by-step. Whether you want to stay on High Sierra but ensure it’s fully up-to-date, or you’re looking to upgrade to a newer macOS version, we’ve got you covered.
Why Update macOS High Sierra?
Before diving into the update process, it’s important to understand why keeping your macOS updated is essential:
- Security: Apple regularly releases updates to patch security vulnerabilities. Staying updated helps protect your Mac from potential threats.
- Performance: Updates often include performance improvements and bug fixes, ensuring your Mac runs smoothly.
- New Features: Each macOS update brings new features and enhancements that can improve your productivity and user experience.
- Compatibility: Updated software ensures better compatibility with new applications and devices.
Preparing for the Update
Before you start the update process, there are a few steps you should take to ensure a smooth transition:
1. Backup Your Data
Updating your macOS involves significant changes to your system. While it’s generally safe, it’s always wise to back up your important data. You can use Time Machine, Apple’s built-in backup solution, to create a full backup of your Mac:
- Connect an external hard drive to your Mac.
- Open System Preferences and click on “Time Machine.”
- Click “Select Backup Disk” and choose your external hard drive.
- Click “Back Up Now” to start the backup process.
2. Check System Requirements
Ensure your Mac meets the system requirements for the version of macOS you plan to install. If you’re staying on High Sierra but want the latest updates, your current setup is fine. However, for newer macOS versions, check Apple’s support page for specific requirements.
3. Free Up Space
Updating macOS requires a significant amount of free disk space. To check your available space, click on the Apple menu and select “About This Mac,” then navigate to the “Storage” tab. Aim to have at least 15-20 GB of free space before starting the update process.
Updating macOS High Sierra
If you want to update macOS High Sierra to the latest point release (e.g., from 10.13.1 to 10.13.6), follow these steps:
- Open the App Store: Click on the Apple menu and select “App Store.”
- Go to the Updates Tab: In the App Store, click on the “Updates” tab.
- Install Updates: Look for macOS updates and click “Update” next to each one. If there are multiple updates, you might see a button labeled “Update All.”
The updates will download and install automatically. Your Mac may restart several times during the process.
Upgrading to a Newer macOS Version
If you’re looking to upgrade from macOS High Sierra to a newer version, such as macOS Mojave, Catalina, Big Sur, or Monterey, follow these steps:
1. Check Compatibility
Not all Macs that can run High Sierra are compatible with newer versions of macOS. Here’s a quick rundown of the minimum Mac models required for each version:
- Mojave: MacBook (Early 2015 or newer), MacBook Air (Mid 2012 or newer), MacBook Pro (Mid 2012 or newer), Mac mini (Late 2012 or newer), iMac (Late 2012 or newer), iMac Pro (2017), Mac Pro (Late 2013; Mid 2010 and Mid 2012 models with recommended Metal-capable GPU).
- Catalina: Similar requirements as Mojave.
- Big Sur: MacBook (2015 or newer), MacBook Air (2013 or newer), MacBook Pro (Late 2013 or newer), Mac mini (2014 or newer), iMac (2014 or newer), iMac Pro (2017 or newer), Mac Pro (2013 or newer).
- Monterey: MacBook (2016 or newer), MacBook Air (Early 2015 or newer), MacBook Pro (Early 2015 or newer), Mac mini (Late 2014 or newer), iMac (Late 2015 or newer), iMac Pro (2017 or newer), Mac Pro (2013 or newer).
2. Download the Installer
Once you’ve confirmed compatibility, download the installer for your desired macOS version from the App Store:
- Open the App Store and search for the macOS version you want to install (e.g., “macOS Mojave”).
- Click the “Get” button to download the installer. The download might take some time, depending on your internet speed.
3. Begin the Installation
After the download is complete, the installer should open automatically. If it doesn’t, you can find it in your Applications folder. Follow these steps to begin the installation:
- Open the installer and click “Continue.”
- Agree to the software license agreement.
- Select the disk where you want to install macOS and click “Install.”
Your Mac will restart several times during the installation process. Ensure your Mac is plugged into a power source to avoid interruptions.
Post-Update Steps
Once the update or upgrade is complete, there are a few additional steps you should take to ensure everything is working correctly:
1. Check for Additional Updates
After upgrading to a new macOS version, there may be additional updates available. Open the App Store and go to the “Updates” tab to install any available updates for your new macOS version.
2. Restore Your Data
If you used Time Machine to back up your data, you can restore it after the update:
- Connect your external hard drive to your Mac.
- Open the Time Machine app and select “Enter Time Machine.”
- Navigate to the files or folders you want to restore and click “Restore.”
3. Update Your Apps
Some applications might require updates to be fully compatible with the new macOS version. Open the App Store and go to the “Updates” tab to check for app updates. Additionally, check for updates directly within non-App Store applications.
Troubleshooting Common Issues
While updating macOS is generally straightforward, you might encounter some issues. Here are solutions to common problems:
1. Insufficient Disk Space
If you don’t have enough disk space for the update, try these solutions:
- Delete unnecessary files and applications.
- Move large files to an external hard drive.
- Use a disk cleanup tool to free up space.
2. Slow Download Speeds
If the update is downloading slowly:
- Ensure you have a stable internet connection.
- Restart your router.
- Try downloading the update at a different time when network traffic is lower.
3. Installation Stuck or Failed
If the installation process is stuck or fails:
- Restart your Mac and try the installation again.
- Boot into Safe Mode (hold the Shift key while your Mac boots) and run the installer.
- Reset the NVRAM (restart your Mac and hold Option + Command + P + R).
Staying Informed
To ensure you always have the latest updates and information about macOS, consider these tips:
- Enable Automatic Updates: Go to System Preferences > Software Update and check the box for “Automatically keep my Mac up to date.”
- Follow Apple News: Keep an eye on announcements from Apple for new macOS versions and updates.
- Join Forums: Participate in Mac user forums and communities to stay informed and get help with any issues.
