How To Update Macos Lion To El Capitan

Download macOS Big Sur

If you're using macOS Mojave or later, get macOS Big Sur via Software Update: Choose Apple menu  > System Preferences, then click Software Update.

“I’m still running OS X 10.10 Yosemite on the MacBook Air, and am resolved to wait until the first bugfix update build at least before committing to an OS X 10.11 El Capitan upgrade on my main. I think you can upgrade to El Capitan. Go to this web page, select your specific Mac model from this list, click on the associated link, and then look form 'Pre-Installed Mac OS'. It will show the maximum version of OS X you can install, and from what I could see chances are you can go to 10.11 (El Capitan).

Or use this link to open the macOS Big Sur page on the App Store: Get macOS Big Sur. Then click the Get button or iCloud download icon.
