My 2013 iMac still has OS 10.12.6 Sierra. Can I upgrade my OS to something newer?
Which OS you can upgrade to will be governed by which model and year your mac is.
An iMac from 2013 can upgrade to either macOS High Sierra 10.13.6, macOS Mojave 10.14.6,
or macOS Catalina 10.15.7.
As your mac can upgrade to the OS's like macOS Mojave 10.14, macOS Catalina 10.15,
I would recommend you upgrade to macOS High Sierra 10.13 first.
For High Sierra, Mojave, Catalina,
Open Safari and click on this link,
How to get older versions of macOS
Go to the Use Safari to download macOS 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.

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'.
