Hi, I am relatively new here but, like many other, I recently updated to the new Mac OS X Lion. After my upgrade, I have had numerous issues with opening programs such as iTunes, Skype, Pages, and even Mail. The error message would simply say that the application quit unexpectedly, and that it would be reported to Apple. Some applications would open and quit some time later, while other applications would not open at all. I've tried reinstalling the applications but the same errors occur. Thank you in advance for your help and advice!
