First question is can you get to any internet site on the Mac? If so, then there’s should be no problem with going to FR and logging on. If you are actually reaching FR and having trouble logging on, make sure your caps lock key is not pressed when entering your password.
Oh, I just read your post. I missed the fact you are surfing FR posts.
If the Caps Lock solution doesn’t solve the log on issue, bring up the NOTES App and try typing something and see if what you type is what you get on the screen. . . especially type your password. Make sure it’s what you expect it to be. I have seen keyboards that are defective once or twice in the past ten years where what is typed is not what appears. Usually, the problem is the language setting is wrong, so the characters that are sent are the wrong character set and therefore the password is wrong. For example choosing the UK English setting and using what you think is a $ in your password and getting the Euro sign instead. No joy in getting into your account.
I can access my email, when I try to access my bank acct it says I need to up date my browser.
