So, I have been having ALOT of issues when installing OS X Yosemite. I was able to solve all of them but this one. When I choose the drive/partition that I want to install over, and it goes through the whole installing thing, once it's close to done, it gives me the following error message: OS X could not be installed on your computer An error occurred while running scripts from the package "Pre.Scripts.pkg". Quit installer to restart your computer and try again. Any suggestions/solutions?
