Get more information about your computer choose Apple menu  > 'About This Mac' in the upper left corner of any window, then "More Info..." or "System Report". Find the year which may not be provided in this information. More about this in "About System Information [Profiler] on your Mac" - https://support.apple.com/HT203001


Use your computer information and the links below to yourself determine what is possible with your computer:


Click on this link to read how to get different versions of macOS - https://support.apple.com/HT211683

- This article also has links to system requirements for each OS version which you should check against your exact computer model. Note some of the model identifier articles are outdated. For any model produced in the last 5 years or so you should use the system requirements links for each OS version instead. This web site also has a reliable presentation of model and OS version compatibility: https://eshop.macsales.com/guides/Mac_OS_X_Compatibility

- Make sure you have more RAM than what is noted as "minimum" for any particular system or your computer may run slowly.

- You may find you need to use Safari to get links for High Sierra and later using the Mac App Store application to open a functioning page.

- Sierra, El Capitan, and Yosemite download as a .pkg. Click on this to have a converted version placed in your Applications folder as an "Install OS..." application. Run the installer and follow the directions.

- Upgrades may take some time (up to an hour or more) to install, with restarts and blank screens.


Back up your data in case something goes wrong --> Back up your Mac with Time Machine - https://support.apple.com/HT201250 or use a cloning tool.


Check if your old apps will still work with with the OS you want to install - https://roaringapps.com/apps This is particularly critical if you are upgrading to Catalina or newer.


Realize that from High Sierra onwards, solid state drives were the standard for computers. This was accompanied by a change in the drive formatting used to APFS. This can be harder on the old style drives and of course newer systems assume that drives are using fast SSDs. I don't have technical details but I know I just don't feel like installing Catalina or newer on my internal drive. Since you didn't mention a computer year for your iMac that leaves quite a bit of interpretation wiggle room into what is perhaps best to expect of your computer.
