To download High Sierra, simply go to the App Store and check the sidebar on the right. If it cannot be found there, you can always search for it. A word of warning, I currently have a late 2011 MacBook Pro running High Sierra and it does not run very well so you should make sure your Mac is running at its best before upgrading.
Apple said that would run happily on a late 2009 or later MacBook or iMac, or a 2010 or later MacBook Air, MacBook Pro, Mac mini or Mac Pro. If you Mac is supported read: How to update to Big Sur.

Macbook Pro Wont Update
Refreshed Dock
A sleek design update makes getting to your favourite apps even easier. And a new uniform shape for app icons adds consistency while letting the personality of Mac shine through.
Control Centre for Mac
Instantly access the controls you use most — like Wi-Fi and Bluetooth — and new controls to play music and enable Dark Mode for your display. Designed just for Mac, the new Control Centre lets you add controls and drag favourites to the menu bar to customise it just for you.
Notification Centre
A new design combines notifications and widgets in a single view for more information at a glance. Notifications are now grouped by app, and many are interactive — letting you do things like play new podcast episodes or learn more about Calendar invitations. And redesigned widgets come in three different sizes, so you can create the best view for you.
Use Software Update
Macbook Air Software Update Now Not Working
Choose System Preferences from the Apple menu , then click Software Update to check for updates.
If any updates are available, click the Update Now button to install them. Or click “More info” to see details about each update and select specific updates to install. You might be asked to enter your administrator password.
When Software Update says that your Mac is up to date, the installed version of macOS and all of its apps are also up to date. That includes Safari, Music, Photos, Books, Messages, Mail, Calendar and FaceTime.
To automatically install future updates, including for apps that you got from the App Store, select 'Automatically keep my Mac up to date'. Your Mac will notify you when updates require it to restart, so you can always choose to install those later.
