Hi everyone, I believe my "Permissions" are the problem.
I let someone change permission settings to share music files wirelessly from their hard drive and mine and another mac (3 in total) yesterday. I seemed to work. I got thier files, and they mine. I can't remember if I then shut down my macbook or just closed it. Anyway last night I was trying to organise the music files and save them to dvd. I also changed the permissions as some of the files were read only. I thought it worked. It seemed to be burning and the screen saver came up, I clicked to exit screen saver and it just went to black for a moment and back to screen saver and i couldn't go any further. I had to hold down the power button to turn it off.
I tried to turn it on and now it's stuck on start up gray screen with the loading wheel thing? just loading forever.
I used disk utility, "verified volume" and "repair disk" are ok, but "verify permissions" and "repair permissions", I get an Error message "the underlying task reported failure on exit"
After reading some posts on Apple Support forums I opened terminal and typed in what a poster said that repaired or reset his permissions,"chmod 775 /Volumes/'Macintosh HD'" and pressed return, Not sure if I should have pressed return or if I should have just closed the window?. Anyway I'm still stuck.
I don't want to try a reinstall as I want to save the music files that I just got yesterday.
I only have the mac since march so I believe I still have phone support, but if anyone can help I'd like to try and sort this out myself and therefore learn more.
