I have an old macbook pro. It's been sitting for a while. I charged it up today to let my daughter use it and I can't log in. I don't even get the option to put in a password. I get to the log in screen and I can't click on anything. I tried the command-r but once it opens again I can't click on any thing. I can use the arrows but they just go round and round. Any help to get into the machine would be deeply appreciated. Blessings, quinlis
