I want to update my operating system on my MacBook Air. I'm using High Sierra but when I go to the App Store, no operating system update appears. How can I update my operating system?
MacBook Air 13″, macOS 10.13
The App Store Updates page only informs you of updates available for the OS you are running.
Installing a newer OS is called an upgrade.
Which OS you can upgrade to will be governed by which model and year your mac is.
Click on the top left of your screen click on About This Mac to find out the year of your mac.
If you find your mac can upgrade to the newer OS's like macOS Mojave 10.14, macOS Catalina 10.15,
or macOs Big Sur 11.6 or even the very latest macOS Monterey I would recommend you upgrade to
macOS High Sierra 10.13 first.
For High Sierra, Mojave or Catalina,
Open Safari and click on this link,
How to get old versions of macOS – Apple Support
Go to Check Compatibility to see if your mac qualifies for the OS upgrade you want.
Then go to the Download OS section and click on the OS you want to install.
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'.
If you want to or are able to upgrade to Monterey open Safari and click on the link below,

If you are considering upgrading to Catalina, Big Sur or Monterey be warned they do not support 32bit apps.
Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,
some updates may be free, some may be paid. Use this free app to discover which apps you have
are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see
if they are offering 64bit updates.
