That is why it is good to have an onboard internet security system, update the MacOSX when they send out new security things. It is good to use VPN, It is good not to "camp out" when you leave your computer. That is stay on a browser even though you went away. It is good to delete your browser history more often than you do. It is good to complete exit out of apps, sites, bank accounts both on your phone and double click everything running inthe background when you are not using.
That is why it is good to use passwords that are different and never store your banking password in the clever "remember password" thing in your browser.
