View Full Version : Play a Single iTunes Library from Two Computers Simultaneously?

15th February 2008, 09:16 PM
Does anybody know if this is possible?
According to this (http://lifehacker.com/software/file-sharing/play-a-single-itunes-library-from-two-computers-simultaneously-312405.php) page, Yes, but it doesn't work for me.
Has anybody tried this and got it working? Any hints to get it going for me?

My setup: MacBook Pro + G5 iMac > Airport > MyBook World Edition
I have all my media stored on the MyBook including music, movies etc.
I would like to have the iMac store it's Music Library on the MyBook and access it from the MacBook Pro simultaneously so that the play counts etc are updated on both machines, but when I try to access it while the iMac has it open, it gives me the following error:

Any ideas?

I'd honestly say don't bother, just using sharing on one machine. Are the play counts that important?

No, not the play counts, that was just an example.
What I want to be able to do is have both computers manage the library (so to speak), so if I add a song or movie on the MBP, then it will show up in the iMac as well without having to manually add it.

With the built-in sharing, if I share from the iMac, then I can't add from the MBP to the iMacs library

I don't think it's possible. There's also a lot that could go wrong if you did find a way to allow both iTunes apps to write to the files.

Totally not possible, of course you can't have 2 machines attempting to possibly write to the same files at once..

If iTunes didn't put a lock down and then check for it. You'd have corruption :)

i have 1 itunes library with 5 zones all able to play songs from that one library simultaneously or interdependantly.

what about remote desktop? one computer controlling what is on the screen of another.

I've been thinking about this as I should (hopefully) be inheriting an eMac soon which I intend to use as a server. I plan to put iTunes on the eMac. All the music will go in one library in the internal disk while another will hold all the video on an external drive (it's not possible to split a library across different disks unless managing everything manually - and I don't want the bother of doing that). I can then load the relevant library as required.

To control the playing I intend to use Screen Sharing. For the sound I can use either AirTunes or the new version of Airfoil which allows sound to be directed from any Mac to any other. That will allow me to play from the one source (and get play counts and correctly updated podcasts) to the room where I'm working. Now if someone wants to write an application which condenses that into a simple utility...

I've managed to do this with a shared disk connected to my airport extreme base station. I copied all my iTunes libraries to one folder on the shared disk. In order to allow all the computers to share the library, I started iTunes on all machines holding down the option key. This allows you to select the iTunes library you want to use. I navigated to the library on the shared disk and hey presto, they all use the same library.

The only thing to look out for is if you add music to the library from one mac, you need to ensure that iTunes is off on the other machines. The reason for this is that when you close iTunes, it saves the library each time. If you save the library from the machine that you did not add to then it does not recognize the new additions.
