How to upgrade Catalina 10.15.6 to Big Sur. Any body with a solution??
My Mac is up to date with Catalina 10.15.7. I need to install MS Office on this laptop but I can't unless I upgrade to Big Sur operating software, as I understand. My mac will NOT upgrade itself to Big Sur. Probably needs a patch software? Appreciate if someone can suggest a solution and steps. Thank you.
