How to Update macOS High Sierra
Updating to High Sierra is simple, but you need to follow the steps carefully to avoid hiccups. Here’s what to do:
Step 1: Check If Your Mac Can Run It
First, make sure your Mac supports High Sierra. Here’s the list of compatible models:
- MacBook (Late 2009 or newer)
- MacBook Pro (Mid 2010 or newer)
- MacBook Air (Late 2010 or newer)
- Mac mini (Mid 2010 or newer)
- iMac (Late 2009 or newer)
- Mac Pro (Mid 2010 or newer)
If your Mac is older than these, it won’t work with High Sierra. You’ll need to stay on your current system or think about getting a newer Mac.
Step 2: Back Up Your Files
Before you update, save your files. It’s rare, but something could go wrong during the process, and a backup keeps you covered. Use Time Machine or copy your files to an external drive.
Step 3: Make Room on Your Mac
High Sierra needs about 8.8 GB of free space to install. To check your storage:
- Click the Apple menu in the top-left corner.
- Choose About This Mac > Storage.
If you’re short on space, delete old files, empty the trash, or move things to an external drive.
Step 4: Download and Install High Sierra
Now you’re ready to get High Sierra. Here’s how:
- Open the App Store on your Mac.
- Search for “macOS High Sierra” or go to Apple’s High Sierra page.
- Hit Download. It might take a while depending on your internet.
- When it’s done, the installer should start on its own. If it doesn’t, find it in your Applications folder and double-click it.
- Follow the instructions on your screen. Your Mac will restart during the process, so save anything you’re working on.
The update can take 30 minutes to an hour, depending on your Mac and connection speed.
What’s New in Update macOS High Sierra?
High Sierra brings some great changes that make your Mac better. Here are the big ones:
1. Apple File System (APFS)
High Sierra switches to APFS, a modern system for managing files. It’s faster at copying files, keeps your data safer with encryption, and works well with SSDs. Your Mac will feel quicker and more reliable.
2. Metal 2
Metal 2 improves graphics performance. If you play games or use apps like Final Cut Pro, you’ll see smoother visuals and faster processing. It’s a nice boost for creative or gaming tasks.
3. Better Photos App
The Photos app gets an upgrade with new editing tools and smarter organization. You can tweak Live Photos, make looping videos, and use advanced options like curves or selective color adjustments.
4. Faster Safari
Safari in High Sierra loads pages quicker and saves energy. It also stops websites from tracking you and blocks auto-playing videos, making browsing cleaner and quieter.
5. Smarter Siri and Spotlight
Siri sounds more natural, and Spotlight search pulls in more useful results, like flight info or web content. These updates make your Mac easier to use every day.
6. Stronger Security
High Sierra adds better protection for your files and system. It’s a key reason to update, especially if you’re on an older macOS version with weaker security.

FAQs About Update macOS High Sierra
1. What are the specific hardware requirements for macOS High Sierra beyond just the Mac model?
While compatible Mac models are mentioned, macOS High Sierra also requires at least 2 GB of RAM and 14.3 GB of available storage for the update. For optimal performance, especially with modern apps, 4 GB of RAM or more is recommended. Some features, like Metal 2, need specific graphics support, which older Macs may lack.
2. What are the potential risks of updating to macOS High Sierra?
Updating can carry risks like data loss if the process is interrupted or fails. Older apps might become incompatible, and on aging hardware, the update could strain components, potentially causing performance issues. Backing up your data beforehand is essential to mitigate these risks.
3. How long does it take to update to macOS High Sierra?
The update duration depends on your internet speed and Mac’s hardware. Downloading the installer typically takes 30 minutes to a few hours, while installation lasts 30 to 60 minutes. Older Macs may take longer, so plan accordingly and avoid interrupting the process.
4. How does macOS High Sierra compare to other versions like Sierra or Mojave?
High Sierra improves on Sierra with APFS for better file management, Metal 2 for enhanced graphics, and stronger security. Compared to Mojave, it lacks features like Dark Mode and Stacks but remains a reliable option for Macs that can’t support later versions.
5. How can I get macOS High Sierra if it’s no longer available on the App Store?
If High Sierra isn’t in the App Store, you can download it from Apple’s official support page or use a direct download link provided by Apple. For Macs on very old versions, you may need to update to an intermediate version (e.g., Sierra) first.
6. How should I prepare my Mac for the update to avoid issues?
To prepare:
-
Check storage: Ensure at least 15 GB of free space.
-
Update apps: Confirm all apps are current to avoid compatibility problems.
-
Run Disk Utility: Use “First Aid” to fix disk errors.
-
Unplug peripherals: Disconnect unnecessary devices to prevent conflicts.
7. What should I do if I encounter error messages during the update?
For errors like “Installation failed”:
-
Restart your Mac and retry.
-
Verify a stable internet connection.
-
Boot into Safe Mode (hold Shift at startup) and attempt the update.
-
Reset NVRAM (Command + Option + P + R on restart). Contact Apple Support if issues persist.
8. Will updating to High Sierra slow down my Mac?
High Sierra generally boosts performance with APFS and better resource use. However, on older Macs (e.g., 2009–2010 models) with limited RAM or hard drives, you might experience slowdowns. Upgrading to an SSD or adding RAM can help.
9. Can I update directly to High Sierra from an older version like OS X Yosemite?
Yes, if your Mac is compatible, you can update from Yosemite or later directly to High Sierra. From older versions like Mavericks, you’ll need to install an intermediate version (e.g., El Capitan) first.
10. Should I consider a clean install of High Sierra instead of updating?
A clean install—erasing your drive and installing High Sierra fresh—can improve performance by clearing out clutter. It requires reinstalling apps and restoring files from a backup, making it ideal for slow Macs or a fresh start, though a standard update is simpler for most users.
