Where can I get a copy of high sierra?

My 2010 Mac Pro is beachballing. Trustd is using all of my processing power. I assume some update of my DAW is responsible. I want to erase my main SSD and reinstall 10.3.6. The link to the APP store leads nowhere. Where can I find a copy of High Sierra?

Before anyone wanders down the,"Don't you think its time to upgrade " path.. All my devices would cost far too much to replace. My clients are content. I was content.

Mac Pro, macOS 10.13

The High Sierra link does work you need to be using your Safari browser for the link to connect to the App Store.


Open Safari and click on this link, 

How to get old versions of macOS – Apple Support

Go to the Download OS section and click on the macOS High Sierra

this will redirect you to the App Store High Sierra download page

it should say Get or Download


It is possible to upgrade to macOS Mojave if your Mac Pro has a 'Metal' compatible

graphics card if you are interested..


Before upgrading make a full back up of your Mac.


Check that third party apps you use have updates available for the new OS.

Check that your printers/ scanners etc have updated drivers and software available for the new OS.


Connect your mac to your router via cable rather than rely on WiFi.

Do not use your mac while it is downloading

and do not use any other devices that share the same internet connection.


If the App Store says ‘Open’ then it is detecting a previous download of the install app

go to the Applications folder locate Install macOS ******.app.

Move it to the Trash, empty the Trash.

Restart, click on the link again, the App Store should say ‘Get' or 'Download'.
