RE: Interesting!
Hi Walkaa,
Perhaps we're talking at cross purposes here...but...
How did you get two accounts to open the same iTunes Library simultaneously? When I try this is doesn't let the second account open the iTunes Library, as the first account has locked it.
Only under the condition of the first iTunes Home Sharing the library can the second iTunes read it.
I performed the following two experiments:
1.a. On a Mac mini, User A opens an iTunes Library on a shared public disk.
1.b. User A has access to the public iTunes Library, but his iTunes locks it.
1.c. User A does not Home Share this library.
1.d. User B, on a MBP computer who has permissions to access the public library on the Mac mini, cannot open the iTunes Library and is informed that the library is "locked" when attempting to do so.
2.a. On the Mac mini, User B opens the same iTunes Library on the shared public disk.
2.b. User B now has access to the public iTunes Library, but his iTunes locks it.
2.c. User B does not Home Share this library.
2.d. User A, on the MBP computer who has permissions to access the public library on the Mac mini, cannot open the iTunes Library and is informed that the library is "locked" when attempting to do so.
Summary, both User A and User B can access the public iTunes Library individually, but not simultaneously, since once one user opens the library it is locked so the other cannot open it. Is this your problem?
So I take it that your system operates differently than what I describe in my Experiments 1 and 2 above. That you can have two accounts that can simultaneously open a single iTunes Library. I find this intriguing, and I'd like to know how it is accomplished.
Home Sharing, of course, is a different mechanism that allows the second account to also read the opened library from the first account's iTunes.
But all this is still superfluous to your problem. And I need to know a little more to understand what you are doing. It sounds like you are saying that both User 1 and User 2 add tracks to the single iTunes Library. Then you say User 1 can't "edit" the tracks added by User 2? What do you mean by "edit"? Are these tracks protected by DRM (or bought through the iTunes Store using different Apple IDs)? If so, then I don't know how to solve your problem, and I suspect you may have to keep both Apple IDs. If these tracks are not protected by DRM or bought using different Apple IDs, then the way of transferring songs from one library to another using the Playlist trick that I described above works well. But you only have a single iTunes Library, so why do you need to transfer the songs in the first place (unless, of course, they are protected by DRM)? You say you need to "move all of my music" from one account to the other. If everything is in one library, then why?
So, if you are trying to get around DRM protections, then I can't help you. If not, then I still don't understand why you are having this problem...stupid me.
