I have a McBook Pro. I have no idea how old it is but I know that it's over 10 years old. I can usually log into my online banking but I no longer can
How do I update my old MacBook Pro so I can use my online banking.
The model year of your MacBook Pro is in Apple menu > About This Mac. The current OS version is also there. If you reply with information about both of those, someone here may be better able to help you.
