I have a problem with my MacBook Pro 2010 13 inch, 2.4 GHz. Originally I had Snow Leopard installed on my Mac, then I was trying to upgrade it to Lion (official version from App Store).
During the installation, an error occurred and I got a kernel panic. But that's not exactly the problem. I found out that the laptop had had a firmware password set by somebody (not me).
None of the boot modifier keys (except option) appear to work. When I press option, it asks me for a password. Some people told me to switch the RAM slots or take one out and then turn on the computer holding ⌘+⌥+P+R. That didn't work either. Still see the password prompt.
Any ideas how to reset it?
