Ever since I installed OS X Mavericks it's been nearly impossible to get anything done. Every time I try to copy a file or install a program I'm assaulted with error messages and failed operations, mostly telling me in one way or another that I don't have the 'rights' to install software on my own computer. I don't know what the problem is.... I've tried 'repairing permissions' and even the 'deep-clean' method via booting into safe mode and running some terminal command.... Anybody else experiencing a similar situation or found a way to once and for all fix your permissions issues??
