My brand spanking new Macbook Pro has died and I don't know how to fix it! I was trying to get my music off my ipod onto my MBP. I got directions off the internet to go to Applications, Terminal and then copy and paste a line of code that shows hidden folders. defaults write com.apple.finder AppleShowAllFiles TRUE killall Finder That worked but then I saw all these other folders in my MBP Hard drive. So i stupidly tried to Trash them and start again. Then it started asking me permission and when i put in my password it was invalid. Then it started freezing up and no applications would open. So i just restarted the computer and got the black screen and a message something like /etc/passwd:No such file or directory and then some numbers and a message like I0Bluetooth HCI something something. I tried to reinstall the applications but when I did it still wasn't working properly and it wouldn't even shut down so i manually shut down. when i restarted it goes from a blinking apple to an X sign (like a circle with a line through it) and alternates back and forth between those two pictures. Sorry that was long- but any ideas?
