Keynote woes
Hi everyone.
I'm trying to open a keynote file sent by a colleague. They created the file on an old macbook running OS Sierra 10.13.6. My macbook is operating on the same system but Keynote will not open the file. Says I need to update to 10.14 or later to download the latest version of Keynote. It appears that is not possible for me to upgrade my OS beyond Sierra and so I cannot download the latest Keynote.
My question is why. Why would a file created on an old version of Keynote not be compatible with the same old version of Keynote?
And is there a way around this other than buying a new laptop??
MacBook Air 13", macOS 10.13
