Mac Mini 2014 password issue
So I bought a refurbed mac mini 2014, when first starting up, entered my apple id and password, password would not work. Clicked setup later. Desktop came up fine. Went to the app store to download something, entered the same password, it logged in fine. Could not download the app said I needed newer os. Downloaded latest os, tried to install but again the password would not work. Restarted and now I can't get in because the password will not work. Trying the password 3 times does not ask to reset password. Command + R will not work, just goes to the screen asking for password. On my ipad and when logging into the apple.com, it shows the mac mini as a trusted device.
