Apple application fails to launch/quits

Question

These steps are generic and should resolve most MAC OSX issues
3 Scenarios
It caused by particular files?
if so rebuild the data base
. These include iphoto itunes mail address book, how you re build differs but it means re ceating a new library from the original content.
Does it happen in a New user account?
if so
removie / move ~Library/Preferences/com.apple.(name of application quitting).plist
should resolve the issue
it is worth trying as a last result
quit EVERY APPLICATION
and remove all login items that are suspect
move ~Library/Preferences (you may only be able to move the contents)to your desktop
and trash the contents of ~Library/Preferences afterwards
log in then out
LAUNCH ONLY THE APPLICATION AFFECTED
if its ok and lanches ok and works 100%
move the contents from the preferences folder on the desktop to the one in the default location
MAKE SURE YOU CHOOSE DO NOT REPLACE

Answer 1

finally if it affects a new user account.
trash
/Library/Caches
~Library/Caches
trash
/Applications/iPhoto
/Library/Receipts/(name of application)**.pkg (you may have multiple .pkgs trash any with the name of the app at the start at the start
Restart MAC
reinstall the application from the install dvd.
if the issue still persists, check your login items for suspect items repair disk permissions and verify disk and check s.m.a.r.t status or even safe boot to isolate further
after all this try backing up and performing and Archive and Install making sure there are no networking elements or external hardware connected that could be related
