The sequence of events: I spilled coffee onto my keyboard, which is connected by cable to my iMac. Unplugged the keyboard (and mouse which was plugged into the keyboard) and tried to get all of the coffee out. Tried to load up my iMac with a wireless keyboard that I don't often use, but which does connect to it. It froze on the WHITE screen. I looked up troubleshooting options and the leading suggestion was a SAFE boot. I did this, and it worked. I got into my computer and it all looked pretty normal. The same suggestions said that there was a good chance that the iMac would now reboot properly, so I restarted it and... Frozen on the BLUE screen. It just keeps flashing a little as it cycles around. I tried the Single User boot with "/sbin/fsck –fy" at the prompt. I had to type that twice for it to come back saying everything was OK. Still freezes on the blue screen when I try to boot. I tried fixing my permissions just in case (1775) and it didn't accomplish anything. I'm freezing on the blue screen every time. But that safe boot worked once, so I have hope... Suggestions?
