My 2009 iMac 20 should be able to upgrade to El Capitan from Yosemite. After download from the site it installs, but I am still at Yosemite. How do I upgrade to El Capitan?

I tried downloading El Capitan from https://support.apple.com/en-us/HT211683 to upgrade from Yosemite but after installing I am still at the old version. How do I upgrade?

You are probably confusing the step where it creates an installer app from a .pkg with actually installing.

- 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.


Before upgrading, back up your data in case something goes wrong. See this support document: Back up your Mac with Time Machine - https://support.apple.com/HT201250 or use a cloning tool.
