Hi, Since last night I experienced some issues with finder. Finder kept crashing constantly and my system was very, very unstable and slow. My system is a Retina MacBook Pro 15" with 16gb of RAM. I never experienced something like this before, it came out of nowhere. When I open activity monitor (very painfully) I see there is almost no CPU and RAM usage. I tried multiple things to fix this but currently am stuck. I want to boot in the recovery disk, so I hold "alt" while booting, after a few seconds I'll get the following screen: http://cl.ly/Nld0 When I enter my admin password I'll get no response, the field clears itself. So I assume it's the wrong one. Where can I find this password?
