I'm using a Mac Book Pro 2011. What do I need to download in order to be able to use Numbers?
Can I use Numbers on my Mac Book Pro 2011? I currently have OS X Yosemite.
MacBook Pro 13", OS X 10.10
The version of Numbers available for download on the App Stop requires a mac running macOS Mojave 10.14.6 or macOS Catalina.
As your mac is from 2011 it can only upgrade as far as macOS High Sierra and you will still not be able to download Numbers.
