Hi,
My mother has a late 2012 i5 500 GB Mac Mini with 4GB of memory. I am concerned that since she is running an older operating system, her system is less secure than if she were to upgrade to El Capitan. On the other hand, I don’t want to make her computer experience any slower. We don’t have the funds to upgrade memory at this time.
Do you feel that the security improvements or overall usability would be worth the upgrade?
