Hello,
I have a mid-2011 27' iMac currently running El Cap (10.11). I want to upgrade to High Sierra (10.13) as that's the last OS that will work on it. When I click on the link to download it from here https://support.apple.com/en-gb/HT208969
It takes me to my App store, but only offers macOS Catalina and I can't find High Sierra on there.
Is there another way to get it please?
Many thanks
Simon

High Sierra is still available.
Open your Safari browser, do not use Firefox it will not work.
Click on this link.
How to upgrade to macOS High Sierra - Apple Support
Go to Section 4 and click on Get macOs High Sierra
this will redirect you to the App Store High Sierra download page.
It should say Get or Download.
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 High Sierra.app.
Move it to the Trash, empty the Trash.
Restart, click on the link again, the App Store should say ‘Get' or 'Download'.

Perfect thank you! I didn't realise I had to use Safari - it wasn't showing up in Firefox.
Many thanks!
