i just bought a macbook pro i7 (lion). put in a password at the start, deided i was the only person who was going to use the macbook, removed the password by simply deleting it in system (?). now my laptop refuses any password when i switch it on. the one i put in at first does not work, no password at all dos not work. the suggstion given is "you can use <apple ID to get your password". the problem is i did not register my laptop with apple before removing my password, i was so eager to play with it. i also bought the apple care pack, and have not even opened the pack yet. i talked to an expert, who said i should re-install the system over the internet, which i did, but there was no difference in the end: same window with my name and the password box, that does not accept anything. who can help? (i am using another laptop to ask this question)
When rebooting or with the system switched off, turn on the laptop, the black screen will change to a white/grey screen (can't remember) before the Apple logo appears, press and hold the lower left Option key, Select the Recovery HD partition and boot up from there.
