Mac not working with online banking site

Are you using VPN? If you are, delete the VPN app and profile. Banking sites frequently don’t work over VPN for security reasons, as it hides your location, and banks want to know where you are to verify you are who you say you are.

Note that Macs run macOS, not iOS. iOS is the name of the iPhone OS and often is used to refer to Apple’s mobile OSes in general.
