How can I update my software if my computer is from 2011?? I think this is ridiculous that I can't update mine and I need to in order for my Adobe programs to work! :(

Welcome!

UGH This computer works fine and is very disappointing that I can even do the necessary updates anymore.

The update to High Sierra is quickly found by doing a search for High Sierra in the Apple Support home page.

That will give you this:

Some notes:

1) Before trying to install, look in your Applications folder and make certain that a High Sierra updater is not already there. IF one is there it will trigger an error. Deleted the older version before downloading the new one.

2)If you need to use a browser to download it, use Safari. THere are numerous repoerts of FireFox not working for Mac suste upgrade files.

3) ⚠️ Back up you hard drive before starting the update.

We are still using a 2011 iMac and it does quite well with High Sierra.

According to this page:

https://jimmytechsf.com/what-system-software-can-my-mac-run/

the latest version of the OS your machine can run is 10.13. OS High Sierra.

If you want to use the latest version of the OS then you'll need to use a machine that is capable of running it. The hardware requirements of each version of the OS grow over time. A machine from 9 years ago just doesn't have the technical wherewithal for the job. And no, if the machine is not capable of doing what you want, then it does not "work fine" any more.

Step 4 in this article should allow you to download High Sierra 10.13.x

Open the link in Safari, Firefox will not work.

The link should open the App Store and show, “Get.” Are you using Safari web browser?

Awesome! Glad you’re able to update your Mac.
