I have been having sooooo many problems in the last 2 years or so with my apple devices...right now, I just got my brand new macbook pro retina 13 " back from apple repair...had installed new drive , logic board...I know its not the hardware, Ive been to apple at least 12 times a year, all they do is reset and reinstall. I do that myself now, its getting soo bad. I had to buy books to try and find my issues, mostly remotes, security, sharing from other computers....I finally narrowed it down when I found a unix root administrator logged on my login page, thats when I knew I was not in control. Sometimes there are users or guests I dont know logged on. I have seen ssh, telnet remotes, ubuntu, ruby, python,etc. and now microsoft exchange, Untitled volumes and no uninstallation of windows in boot camp option. Apple doesnt know what I can do, its over my head now. I hope that if I can find windows and remove it from my mac it might help, right now I dont have permissions do do anything and traced it to a volume on my external drive, which is on my harddrive now, somewhere. This is where I stop. I cant go on alone. I have tried but am totally stuck...can anyone help me? Its getting impossible to do anything on any of my devices anymore! Sim.
