I have a problem with the MacPro. It has slowed down significantly. "open error 5 input/output error an applications/textedit/app/ contents. there is more but I can't get to the end of the sentence. It is a xeon Intell. Can't find the paper work as we are remodeling. Can you give me a clue as to what I need to do. The little rainbow button is going round and round and it has gone from hyperspeed to slow speed. I am pretty fresh from PC to Mac and I knew there would be problems. Just depend on your expertise to help me straighten these out. If I have to use the CD's how do I attach and use my WD external HD that is preformatted for a PC for back up? One thing at a time, I know.
I have run the utility twice for verify and repair. Cannot repair. Any help?
