Dock crashes after Yosemite install, account unusable

[allenkt]

I installed Yosemite on my early 2013 iMac yesterday and have mostly been unable to use my account since the install.

The first clue that something was wrong was that it took literally 4 minutes to log on to my account. I would type in my password and it would spin and sit there until 4 minutes later when it let me in (I timed it).

Then the first time, my dock was flashing for awhile then went away (I do not have it hidden) and everything was painfully slow. Once I finally got my console open I could see the dock was crashing approximately every 40 second. There were some other error messages but they all seemed related to the dock.

I first tried to repair disk permissions but that was so slow it wasn't even useful. I tried it last night, then let it run overnight and when I got up it had fixed maybe 10 items (all related to the printer) and said I had 11 hours left.

I went to my library/preferences and deleted the dock.plist, then rebooted but that didn't have any effect.

But it only seems to be my account. I am now logged on to the guest account and everything seems to be working. I ran the repair disk permissions and it took 2 minutes, found a few things and fixed them.

I'm not sure how I can copy the error messages or access them from the guest account in order to paste them here. If I tried to post this message from my account the lag is so bad that it would literally take me at least 45 minutes just to open Safari, open the console, and post a message.

Any advice would be greatly appreciated.

Well now I can't even log on anymore. Tried booting into safe mode to see if it still crashed. Rebooted, had the red "safe mode" on the top right of screen, but unable to log on. Put in my password and it sat there with the spinning rainbow for 15 minutes. Rebooted to get out of safe mode, tried to log on but same thing. I gave it 30 minutes then rebooted again. Now trying to log in to guest account but it's not letting me do that either. No clue what to do next.

I do have time machine set up on an external drive but not sure if the last backup was from Yosemite or Mavericks. But I don't even know how to get to it. Unfortunately I've only been on Macs for a year so all I really know is Windows.

And for what it's worth, I did buy the 3 year AppleCare Plus for it so it's still under warranty. I'm about to chuck it out the window then take it to the Apple Store. Ok, not really but this is frustrating.......I don't have time for this

This just keeps getting worse. I've done a nvram reset, no change. I was able to log in to my daughter's account so I deleted some programs that I never use and updated MS Office just for the fun of it. I also created another admin account in case I could simply switch accounts but now I'm not sure.

After doing all the changes I could think of in my daughter's account I rebooted the computer. And......now I can't get back in to hers either. The rainbow spins and it freezes (the clock in the top right never changes so I assume it's frozen).

So what seems to be happening is that I'm allowed to use accounts once, then something happens and I can't get back in. I've used my account, the guest account, and my daughter's, and now all of them freeze the computer. I still have two more accounts I can use in case anyone thinks of something to try. And I can I can just create new accounts every time I get in. But man, what a pain this is.
