Upgrading Late 2009 Imac using Mavericks operating system

I am in Australia and want to upgrade my operating system from 10.9.5 Mavericks on my Late 2009 21.5 inch Imac.

Hi there,


Try choosing High Sierra in this link: How to get old versions of macOS - Apple Support. Backup before installing!


Cheers,
