Is it possible to get Keynote/Pages/Numbers for El Capitan? I received an older MacBook Pro 5,1 (MacBook Pro 15” Unibody, Late 2008 / Early 2009), but it came without a hard drive. I installed Mountain Lion from DVD, then updated to El Capitan, which is the latest version of macOS supported by this laptop.

I am now unable to install Keynote—or any iWork app—because they all require macOS Sierra. What can I do?
Here’s the deal:


iWork requires macOS Sierra (or whatever the latest OS version is at the time) to “purchase.”
You can install the latest compatible version onto your computer, but only if you already have that iWork app associated with your Apple ID.


So the solution is to:


Get access to a Mac with macOS 10.12 Sierra installed.
Create a guest account with your Apple ID and use it to login to the Mac App Store.
“Purchase” Keynote, Pages and Numbers.
Now if you go back to your older Mac, these products will be associated with your Apple ID, and the Mac App Store will offer to install the latest compatible version.
