If you create another admin user account, does it have the same problems?
Do you have the same problem if you boot into the Safe Mode?
You may need to rebuild permissions on your user account.
To do this, boot to your Recovery partition (holding down the Command and R keys while booting) and open Terminal from the Utilities menu.
In Terminal, type: 'resetpassword' (without the 's) and select the admin user. You are not going to reset your password.
Click on the icon for your Macs hard drive at the top. From the drop down below it select the user account which is having issues. At the bottom of the window, you'll see an area labeled Restore Home Directory Permissions and ACLs. Click the reset button there. The process takes a few minutes. When complete, restart.
Is iPhoto in your Time Machine Backup?
Thanks, Eric. I'll try your suggestions.
Re: iPhoto, it wasn't on my Time Machine drive, but it turns out I was looking at the wrong system restore disk for the wrong Mac. Anyway, I was able to install iPhoto, but it quits on launch now. I didn't see anything in the crash repont about permissions, but something about a library not loading because the image wasn't found.
Thanks, Linc. Resetting my user permissions and ACL's fixed my problems. I can sync to iTunes and launch iPhoto. I'll see if my kernal panics go away too.
It took me awhile before I attempted this because I wanted to research it more. Apple went through a lot of trouble to hid this tool from users. That usually means something.
