My macbook system froze and I shut down by pressing the power button. I\nwaited 30 seconds and then restarted the machine. It booted up slowly\n- it had been running for several days without a restart. I opened\nterminal to run the crons and it will not take my administrator\npassword, although I have not problem using it for login, accounts and\nother functions. Read like a familiar problem to anyone?
