Apple’s macOS has undergone significant transformations over the years, with each new version bringing exciting features, improvements, and security enhancements. For users still operating on older versions like Lion, the prospect of upgrading to a more recent version like High Sierra can be both enticing and daunting. This article aims to provide a detailed guide on whether and how you can upgrade from Lion to High Sierra, covering the process, requirements, and considerations you need to be aware of.
Introduction to macOS High Sierra
Before diving into the upgrade process, it’s essential to understand what macOS High Sierra offers. Released in 2017, High Sierra is the 14th major release of macOS, focusing on performance, security, and reliability. It introduces APFS (Apple File System), which replaces the older HFS Plus, offering better security and performance. High Sierra also includes Metal 2, an updated version of Apple’s graphics API, which provides a more efficient and powerful way to tap into the graphics processing unit (GPU). Additionally, it enhances Safari, providing better privacy and security features, such as intelligent tracking prevention.
System Requirements for High Sierra
To upgrade to High Sierra, your Mac must meet specific system requirements. These include:
- Mac Model: High Sierra supports a range of Mac models, including MacBook (late 2009 or later), MacBook Air (2010 or later), MacBook Pro (2010 or later), Mac Mini (2010 or later), iMac (late 2009 or later), and Mac Pro (2010 or later).
- Processor: Your Mac needs at least a 2GB RAM (4GB recommended) and a 64-bit processor.
- Storage: You’ll need at least 14.3GB of free disk space to upgrade.
Upgrading from Lion
Upgrading directly from Lion (macOS 10.7) to High Sierra (macOS 10.13) is not straightforward due to Apple’s upgrade path limitations. Typically, Apple only supports upgrading to a new version of macOS from the last two versions. Since Lion is several versions behind High Sierra, you cannot directly upgrade. However, there are a couple of strategies you can employ:
Strategy 1: Incremental Upgrades
One approach is to perform incremental upgrades, moving from Lion to a version that can then be upgraded to High Sierra. For example, you could upgrade from Lion to Mountain Lion (10.8), then to Mavericks (10.9), Yosemite (10.10), El Capitan (10.11), and finally to Sierra (10.12) or directly to High Sierra if your Mac model supports it. This method requires patience and careful planning, ensuring each version is compatible with your hardware and that you have enough disk space for each upgrade.
Strategy 2: Clean Installation
Another strategy involves performing a clean installation of High Sierra. This method requires you to back up your data, then erase your Mac’s hard drive and install High Sierra from scratch. Before doing this, ensure your Mac model is compatible with High Sierra and that you have the installation media (you can download it from Apple’s support page if you have a valid purchase). This approach gives you a fresh start but requires you to reinstall all your applications and restore your data from backups.
Preparing for the Upgrade
Whether you choose incremental upgrades or a clean installation, preparation is key. Here are some steps to take:
- Backup Your Data: Use Time Machine or another backup solution to ensure all your important files and data are safely stored. Upgrading or reinstalling macOS can sometimes lead to data loss.
- Check for Compatibility: Verify that all your essential applications are compatible with High Sierra. Some older apps might not work properly or at all on newer versions of macOS.
- Free Up Disk Space: Ensure you have enough free space on your Mac. Upgrading requires significant disk space, and having more free space can help prevent issues during the upgrade process.
Conclusion
Upgrading from Lion to High Sierra is possible but requires careful consideration and planning. By understanding the system requirements, choosing the right upgrade strategy, and preparing your Mac, you can successfully move to High Sierra and enjoy its features and security enhancements. Remember, staying up-to-date with the latest macOS version is crucial for maintaining the security and performance of your Mac. If you’re unsure about any part of the process, consider consulting Apple’s official documentation or seeking help from an Apple Support specialist.
Given the complexity and the potential risks involved in upgrading across such a wide version gap, it’s also worth considering whether upgrading your hardware might be a more viable option, especially if your Mac is aging and might not support future versions of macOS beyond High Sierra. Regardless of the path you choose, taking the time to understand your options and prepare thoroughly will make the transition smoother and less stressful.
What are the system requirements for upgrading to High Sierra from Lion?

How do I prepare my Mac for the upgrade from Lion to High Sierra?
Preparing your Mac for the upgrade from Lion to High Sierra involves several steps. First, you need to back up your important files and data to an external drive or cloud storage service.

Upgrading to an intermediate version first ensures that your Mac is compatible with the latest software and security updates. You can download the intermediate version from the App Store or Apple’s website and follow the installation instructions.
Once you’ve upgraded to an intermediate version, you can then upgrade to High Sierra. This may seem like a lengthy process, but it’s essential to ensure a smooth transition and compatibility with the new operating system. You can check Apple’s website for the recommended upgrade path and instructions specific to your Mac model and current operating system. By following the recommended upgrade path, you can ensure a successful upgrade and enjoy the new features and improvements of High Sierra. It’s also a good idea to back up your Mac before upgrading to an intermediate version, as this will ensure that your data is safe in case something goes wrong during the upgrade process.
What are the key features and improvements in High Sierra compared to Lion?
High Sierra offers several key features and improvements compared to Lion. One of the most significant updates is the new Apple File System (APFS), which replaces the traditional HFS+ file system. APFS provides improved performance, security, and reliability, making it a significant upgrade over the older file system. High Sierra also includes updates to the Photos app, Safari browser, and Mail client, as well as improved support for graphics and video editing. Additionally, High Sierra includes enhanced security features, such as improved encryption and better protection against malware and other online threats.
Another significant improvement in High Sierra is the updated graphics and video capabilities.

The upgrade process from Lion to High Sierra can take several hours, depending on the speed of your Mac and the amount of data that needs to be transferred. The actual installation process typically takes around 30 minutes to an hour, but the overall upgrade process can take longer due to the need to download the installation files, back up your data, and perform other preparatory steps. You should also factor in the time it takes to upgrade to an intermediate version first, as this can add several hours to the overall process.
It’s essential to be patient and not interrupt the upgrade process, as this can cause issues or corruption. You should also ensure that your Mac is plugged into a power source and has a stable internet connection to prevent any interruptions or errors. Once the upgrade process is complete, you can enjoy the new features and improvements of High Sierra.

You can also check the App Store for updated versions of your favorite apps, as many developers have released High Sierra-compatible versions.
If you have any apps or software that are not compatible with High Sierra, you may need to find alternative apps or upgrade to newer versions. This can be a good opportunity to clean up your Mac’s app collection and get rid of any apps you no longer use or need. You can also use the App Store to discover new apps and software that are compatible with High Sierra. By taking the time to check app compatibility and update your apps, you can ensure a smooth transition to High Sierra and enjoy the new features and improvements without any issues or complications.
