Previously, whenever a major new version of macOS (or OS X) would launch on the Mac App Store, the previous version would still be available for download in the Purchased tab on the store. But things have changed this year. Now that macOS High Sierra has launched, its predecessor, Sierra, is nowhere to be found.
It appears that updates for macOS are no longer tied to your Apple ID, which explains why Sierra and High Sierra don't show up in your Purchased tab. However, Sierra is also missing when you search for it in the Mac App Store.
You were only able to use macOS High Sierra operating system on Mac or any other version of Mac, but in this article, I will show how you can install this operating system on VMware Workstation Pro.

Jan 21, 2018 iMac, macOS High Sierra (10.13.2), antivirus program Posted on Jan 18, 2018 10:25 PM Reply I have this question too ( 79 ) I have this question too Me too (79) Me too. September 20 is macOS Sierra day, where the latest version of the Mac operating system will be available for free in the App Store. But first things first: Is your Mac compatible with Sierra?
As Stephen Hackett of 512 Pixels notes:
This means there's no easy way for someone to install macOS Sierra at this point. If your Mac came with 10.12.4 or greater, you can reinstall that version from Apple's servers, but going back from High Sierra isn't doable unless you've got a copy of Sierra laying around.
As Hackett goes on to note, it's likely that at least part of this move is motivated by Apple's desire for Macs running Sierra to upgrade to High Sierra, which offers many refinements of the Sierra experience. It's also worth noting that, at least for Macs with internal SSDs, downgrading from High Sierra would be more difficult thanks to the APFS transition.
