Can't download keynote

When you advise about your hardware product description and the current version of macOS that you are running from that About This Mac panel, we can determine if there is a further upgrade path for your Mac or not.

If you ever installed Keynote from the Mac App Store since Oct 2013, you may be able to get the last compatible version for your current operating system. Launch the Mac App Store and sign in with the identical Apple ID that was used to install Keynote previously. If you are on macOS Mojave or later, press cmd+0 (zero) to open the Mac App Store's Purchased panel. If you see Keynote there with an update/download button or a blue cloud icon, then click that to get the last compatible Keynote version for your release of macOS.

If you never previously installed Keynote from the Mac App Store, then you will need the ability to run macOS 12.3 or later to install it. Apple does not maintain a download site for past full Keynote installers.
