My credit card company insists I upgrade the macOS in order to access my CC account
I have a 2017 MacBook Pro with Ventura OS. My credit card company insists I upgrade the OS in order to access my CC account. I don't really want to, nor do I know if an upgrade is available. My computer says it's up to date. What do I do?
