Download and install macOS High Sierra beta 6 on your Mac

Apple announced macOS High Sierra at WWDC 2017 with a number of new features as well as under-the-hood updates. While not a major update, High Sierra is full of refinements that will bring improved performance and stability (because of APFS), smooth system animations (thanks to Metal 2), better Siri functionality and of course, the most important of all, a snappier Safari. You can download macOS High Sierra as a developer preview. Find out how using our guide.

 

Download macOS High Sierra

 

Before you begin, note the following:

  1. Make sure that you have backed up your data. A bootable USB drive is normally used for a clean install so your Mac data will be formatted.
  2. Whether your Mac is compatible or not. macOS High Sierra supports the same Macs as Sierra did:
    • iMac (Late 2009 or newer)
    • MacBook (Late 2009 or newer)
    • MacBook Pro (Mid 2010 or newer)
    • MacBook Air (Late 2010 or newer)
    • Mac mini (Mid 2010 or newer)
    • Mac Pro (Mid 2010 or newer)
  3. Don’t try this on your daily driver. Since macOS High Sierra is a developer beta right now, it has stability issues and is likely to crash often. You might want to wait for the public beta which will be released later this month.

At the time of writing, macOS High Sierra beta 6 is available for download.

New developer APIs include CoreML, Swift 4, APFS, updates to WebKit and HEVC. Apps like Messages, Notes, Safari, Siri, iCloud Drive and FaceTime have also been updated.
