How do I update to macOS Big Sur?

The link for older Mac OS does not let you install Big Sur, if you click on 'How to install Big Sur' it takes you to a page to macOS Monterey :-(


I need to update to Big Sur too and not Monterey as some software I run is not yet compatible on Monterey.

There is a download link here to get the Big Sur installer..

Or I should say it Says that's what it is!!


macOS Big Sur 11 can upgrade Catalina, Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks

The blue link ^ goes to: https://apps.apple.com/us/app/macos-big-sur/id1526878132?mt=12


These are located in Support article:

• How to get old versions of macOS - Apple Support

https://support.apple.com/en-us/HT211683


Additional info and instructions are within above.


Most of these upgrades are like a one-way ticket; even

if you do create a great backup strategy (in triplicate.)


Your issue may be relocated to form new separate thread.

Good luck & happy trails!🌤🌿🌻❄️

With ever new macOS release we run into this monkey wrench as the past installer get shuffled around —

the Big Sur installer may take some days before it comes back to the surface and available.


You can from the Terminal.app to initiate the Big Sur installer, copy and paste:

softwareupdate --fetch-full-installer --full-installer-version 11.6
