Both me and my wife use the iMac. One computer, two users. Last night I attempted to make a shared folder for our itunes music. After 6hrs, I finally went to bed without it working properly. Today another 4hrs and it's still not working properly. I have attempted the external hard drive option, scratched that idea, then today created a shared folder where I put my Itunes Library, enabled permissions and thought I had it. When she logs on, she seems to have everything I put into the library. I bought a song under her account on Itunes to see if I could see it when I logged in to my account. When I log in, I see the song I bought under her account, but about 3000 of my other songs won't open "Original file could not be found. Would you like to locate it?" comes up when I click on them. Where the hell did my songs go and how come they are now working for her. I have read literally hundreds of posts in an attempt to make this work. This is ridiculous how hard Apple makes it to share a freakin library on the same computer. Please help before this new iMac gets damaged.
