I have a macbook pro with Yosemite. The problem I have with it is that the applications only work in safe boot. However, I found a fix for this by opening photo booth, putting on a 10 hour video and waiting 10 hours. Usually this would solve the problem with Photo Booth opening along with the rest of my applications. But now this fix is not working anymore. 10 hours would pass but applications would still not open. I have tried everything to fix this issue such as: - repairing disk permissions - making a new user account - uninstalling and reinstalling Yosemite Nothing worked! The only thing that ever worked was the 10 hour trick but now even that's not working anymore. Please help because I have an important project to get done. And I do it if my computer is acting this way. Any help is highly appreciated!
