Independent High Sierra Download

Hello,

I am using MacOS Mojave, and resisting the upgrade to Catalina as I will no longer be able to use Adobe Acrobat CS6 which is no longer supported, and after paying a lot of money I'm disappointed that it will no longer work.

I do use Parallels, and was wondering if there is a chance of obtaining a copy of MacOS High Sierra so I can install that? That way I can run Acrobat.

The links to MacOs High Sierra take me to the Mac App Store, but I get the impression that will erase my disk.

Any help would be much appreciated.

Thank you.

So I successfully downloaded macOS High Sierra, and I did get that little warning panel, but ignore it.

Install macOS High Sierra.app is now in my Applications folder and should be in yours. There is no need to delete it and download again, ignore that advice as well.

Make a bootable USB installer using the instructions here, How to create a bootable installer for macOS – Apple Support

Consult the instructions for Parallels on how to install macOS.

Hello,

Thanks for your response.

I tried to download MacOS High Sierra and I get the message

"The copy of the "Install macOS" application is too old to be opened on this version of macOS.

I am on a mac running macOS Mojave, and at the App Store High Sierra page I click on Get and

Software Update opens and after a few minutes I get this,

After clicking Download, it does start to download.

The Open reference in your error message may allied to the fact you already have

High Sierra on your mac, could this be the case, look for Install macOS High Sierra.app

in your Applications folder, or any where on your mac.

Do you have another mac you can download it to

and then transfer to your Mojave mac.

Hello everyone who has chipped in with advice,

Firstly wanted to say thank you to everyone, I've installed it.

Parallels recognised the file with no problem. For my records I've saved the OS for the future.

I'm posting these pictures for others.

At the High Sierra App Store page just press 'Get' to start downloading High Sierra, this will download to your Applications folder as Install macOS High Sierra.app. Your disk will not be erased, only you can do that.
