Unfortunately, the iMac (Early 2009) is not able to run the latest macOS version, macOS Sierra. However, you don’t have to worry – there are still some ways to upgrade your system!
The latest OS that the iMac (Early 2009) can run is Mac OS X 10.11 El Capitan. If you want to upgrade your system, you will need to locate a copy of 10.11 El Capitan from either an online mirror or from someone who already has a copy of it.
Once you have located a copy of 10.11 El Capitan, all you will need to do is install it on your iMac (Early 2009). This process should be relatively simple and straightforward and shouldn’t take too long. Once installed, your iMac (Early 2009) will be running the latest version available for this model.

Updating a 2009 Mac Desktop
Yes, you can update your 2009 Mac desktop. You can upgrade to the latest macOS Sierra operating system which will give you access to the latest features and security updates. Additionally, you can upgrade the hard drive or memory of your Mac desktop to boost its performance and extend its lifespan. This is especially beneficial for older models like the Late 2009 iMac, as it may be considered vintage but is still compatible with macOS Sierra.
