Most of the application fail to launch
After installing Mavericks, most of the applications on my computer couldn't not be opened.
I have no problem on the first few hours but after that lots of application that I have on my computer can't be open (eg. iMessage, FaceTime, Maps, Preview, App Store...)
Anyone have a solution on this problem or have similar problem?
MacBook (13-inch Aluminum Late 2008), OS X Mavericks (10.9)
