Apple have released a developer beta of their upcoming operating system named macOS High Sierra, which will be macOS 10.13. The name High Sierra continues on with their California landmarks with the name after a scenic CA region, it should be publicly available between September to November.

Lucklily for most the new macOS High Sierra 10.13 will run on the same machines as its predecessor macOS Sierra 10.12. Apple had already dropped support for any models pre late 2009 for MacBook and iMac. And anything pre 2010 for MacBook Air, MacBook Pro, Mac Mini and Mac Pro.

• It can be the same computer as the one mentioned in the previous point. If your computer already has macOS installed, High Sierra Installer will update macOS normally, without deleting any of your apps or files. MacOS High Sierra needs its own hard drive partition, a minimum of 10 GB of space is required, but at least 50 GB of space is recommended.
• Now increase the size of Memory for macOS High Sierra from 2 GB to 4 GB for better installation performance.

You’ll still require a 64bit Intel processor, 8GBs of free disk space – if upgrading, as appose to clean install min plus at least 2GB of RAM.

The Macs that will run macOS Sierra

• iMac – all models from late 2009, iMac 10,1 – 17,1
• MacBook & MacBook Retina – all models from late 2009, MacBook 6,1 – 9,1
• MacBook Pro – all models from 2010, MacBook Pro 7,1 – 11,5
• MacBookAir – all models from 2010, MacBook Air 3,1 – 7,2
• Mac Mini – all models from 2010, Mac Mini 4,1 – 7,1
• Mac Pro – all models from 2010, Mac Pro 5,1 – 6,1

Which means most devices made prior to 2008 won’t be able to run it.

The ones that fall short…
