Few days ago Mac Mail started making fast, loud, continuous beeping sounds while I was writing a long document. The Mail program started flashing, "vibrating," and froze. I had to force quit and lost that email (right - I should have saved it, but didn't). I tried to re-create the document in Pages and the same thing happened. Then I tried to recreate it in Word. Same thing. (may sound nuts to just keep trying new programs, but this was an urgent document. Figured I could get it done, then focus on fixing the problem)
When I finally got things working again by re-starting multiple times and using Disk Utility, I evenutally opened iPhoto. After working with that program for several hours, I tried to use "share, "which creates an email with a jpeg. The same beeping and flashing started again. I had to shut down the computer. Next day everything seemed OK. No problems for 3 days.
Tonight I was working with several programs, all doing fine. Then I opened iPhoto and it immediately started the fast beeping and wouldn't let me access any of my MANY photos. Had to force quit. So I tried to access photos I saved in Finder. Every saved photo (I have hundreds in Finder) would beep and flash continuously when I clicked on it's icon, even without opening it.
I can't find anything online about this situation. Some articles and forums talk about 3 beeps having a certain meaning. That's not what this is. It's continuous loud rhythmic beeps, flashing and I can barely shut down the program when that's going on.
Background: right before this started, my HD was very full and giving me warnings, so I deleted numerous file. It's possible I could have deleted something that should NOT have been deleted. I also started in PRAM mode. If I deleted something, I don't know how to tell what's missing. Also, iPhoto is very full and gave me warnings not to add photos. My Mac is 5 years old and running pretty fast. I installed Mountain Lion several months ago.
Has anyone experienced this? Help!! I don't want to lose my photos!
