On your Mac, open Apple menu >> System Settings >> General >> Software Update.
Your Mac will check for available updates. If an update is offered, select Update, Upgrade, or Restart Now, depending on what is shown, and follow the onscreen instructions.
If you are asking about upgrading to the latest major version of macOS, the information provided, iMac 21.5-inch, macOS 15.7, is not enough to determine which major macOS versions your Mac supports.
The exact iMac model or model year is needed.
To identify it, choose Apple menu >> About This Mac and note the model information shown there.
You can then check Apple's compatibility lists for the newer macOS versions:
macOS 26 Tahoe: Apple — macOS Tahoe compatible Mac models
macOS 27 Golden Gate: Apple — macOS Golden Gate compatible Mac models
If your Mac is not listed as compatible with a particular macOS version, that version will not normally be offered through Software Update.
In that case, the Software Update screen will show whatever updates are available for your particular Mac.
