How a spare administrative account works to troubleshoot
It is easy to know that there might be corrupt preference files on your Mac when there are always application freezing and OS X stalling and displaying dreaded rainbow cursors. Yet it will be difficult for you to make sure which preference files are broken.

Preference files of OS X and applications usually store in different places, and can be found in the folder /Library/preferences/ and the /user/Library/Preferences/ folder. To identify the culprit, you may in to log out the user account and log in the spare account, which has clean and untouched preference files.

Step 1: Log in the spare account, and then launch the applications to see whether the problems occur, if not, you can judge that the preference files in the /username/Library/Preferences/ folder are broken.
If the problems with your OS X or applications still exist after you have logged in your spare account, preference files located in /Library/Preferences/ might be the corrupt ones.

Step 2: Once you have made sure which folder stores the broken preferences files, navigate to the target folder and then trash the corrupt preference files might be helpful to solve the OS X or application problems.
