Apple launched macOS High Sierra on 25 September 2017. It brings new core technologies, including an entirely new file system, opportunities for Virtual Reality, and refinements to apps such as Safari, Photos and Mail.
You can read more about High Sierra here. What you'll be wondering, though, is will macOS High Sierra work on your Mac? The older a Mac gets, the greater the risk that it might not be up to the task of running a brand-new OS.
Which Macs are compatible with macOS High Sierra?
Before we get into physical system requirements, there's the question of whether or not your Mac will be eligible for Sierra full stop. Here is a full list of the Macs that will be able to download the upgrade:
- MacBook (Late 2009 or later)
- MacBook Air (2010 or later)
- MacBook Pro (2010 or later)
- Mac mini (2010 or later)
- Mac Pro (2010 or later)
- iMac (Late 2009 or later)
Obviously, it's disappointing to find out that your Mac isn't compatible, particularly when El Capitan was available to Macs stretching back to 2007. However, this stretch back to support seven-year-old machines is good work by Apple, considering it sometimes drops device support for iOS update long before they reach the ripe old age of seven.
All is not lost - if you do want to run High Sierra on an older Mac you can read about how to install macOS High Sierra on older Mac here.
