At WWDC on Monday Apple announced and subsequently released macOS Mojave 10.14 developer beta. Unlike High Sierra, though, this update does not run on all the same Macs that the previous/current version does, with 2011-and-earlier Macs being left behind.
Macs that can run the macOS Mojave 10.14 Beta include:
- 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, plus mid 2010 and mid 2012 models with recommended Metal-capable GPU. Support for 2010 and 2012 models will be available in an upcoming beta).
This means that High Sierra is the last version of macOS that will run on:
- MacBook (Late 2009 to Mid 2010)
- MacBook Pro (Mid 2010 to Late 2011)
- MacBook Air (Late 2010 to Mid 2011)
- Mac mini (Mid 2010 to Mid 2011)
- iMac (Late 2009 to Late 2011)
Developers with compatible Macs can download the macOS Mojave 10.14 Beta now from developer.apple.com.
