Basic Fast OSX Troubleshooting

 Basic Fast OSX Troubleshooting

1. Restart and test
If the machine has slowed to a crawl, or if your applications are freezing, restarting is the first thing to try.

2. Restart with Startup Items Disabled
Restart and hold down the shift key. Continue to hold it until the desktop background appears. If one of these items was causing a conflict with the software you were trying to use, you will not see crashes or freezes.

3. Switch to a Clean Test Account
Log in to a separate account, ideally a test account set up in advance for just such occasions. If the problem does not occur in the test account, it’s likely due to a file that affects only your Home account.
If the problem is with one application.
Log back into your account, delete the plist (preference) for that application.
Users Folder - Your Account Folder - Library Folder - Preferences Folder - the plist should contain the name of the application - move it to the desktop and logout and login and test.
If that does not solve a problem for a specific application problem, reinstall the application.
