I would like to keep my iTunes 10.7 for use when I DJ, because it allows me to keep multiple playlist windows open as well as the main music library window open, all simultaneously.


However, I can no longer synch my iPhone (5, OS 7) because it needs the latest iTunes 11. Is it possible to have both installed, one that I would only use for synching some musi

    No. There can only be one version installed at a time. You can, however, have two versions of OS X installed if you partition your hard drive and put the other version on that partition.

    If I were to do that, are you saying that each operating system could or would have a different version of iTunes on it? I'm running 10.6.8 now, what would I put on the other partition?

  • Kappy Level 10 (265,676 points)

    Well, what you could do is this:


    1. Create a small partition of about 50 GBs.

    2. Install a fresh copy of Snow Leopard on that partition.

    3. Do not upgrade iTunes to 11.x or later.


    Option boot from this copy of Snow Leopard when you need to use iTunes. Keep the iTunes Library on this partition.


    Don't upgrade this partition should you decide to upgrade OS X. Upgrade only your main boot partition.

    Does it matter which version of iTunes I store where? I'd prefer to put iTunes 11 on the new partition since I will only use it to occasionally synch music to phone.

    iTunes is stored in the Applications folder, normally. The new user account will create a separate set of support files in the new user account, but will run the application in the Applications folder. What differentiates each is kept separately in each user account.


    Because the new user account is new, he will create a whole new set of preferences and support files for all the applications he normally uses. He will also need to have his own separate iTunes Library because he no longer can use the one you use. All purchased items in the extant iTunes Library are no longer usable by him. He will have to re-purchase for himself or you will need to create a sharing connection between each user such as by Home Sharing.


    Understanding Home Sharing

    iTunes- Setting up Home Sharing on your computer

    iOS- Setting up Home Sharing on your device

    okay thanks Kappy, I may write again when I try to execute all this!

    I shared this conversation with a friend, who thought that creating the additional partition would erase my drive? He also thought I could accomplish the same thing using an external drive. Do either of these things sound accurate to you?

  • Kappy Level 10 (265,676 points)

    As much as I hate to tell you this, find a new friend, because yours doesn't know what he is talking about. Here's how it's done, and it doesn't erase your drive to do it. To answer your second question, yes, you can do this on an external drive, but then your husband will have a slower system to work with, and that drive can never be disconnected or allowed to shut down.


    To resize the drive do the following:


    1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.


    2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.




    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)


    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.


    You should now have a new volume on the drive.


    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.

    I followed all those instructions and have the new partition, renamed. But how do I install Snow Leopard on there? I have the disc, but if I choose Options to select a different drive, it won't let me choose the new one.

    When I reboot and hold the C down, or the Option key down, it won't start up from Snow Leopard, it just stays on the gray screen with the wheel spinning forever....

    Hold Option when booting then you can select the CD to boot from.

  • eliezering Level 1 (0 points)

    No, I said when I hold OPTION down it allows me to select the CD, but the CD won't start-up.

    and this is is the SL System Install disc that came with your computer?

    Not the extras disc?

    Or did you purhase the retail version?

  • eliezering Level 1 (0 points)

    I'm just now realizing/remembering that the computer came with 10.5 disc, which I still have, and will try that instead. Yes, I bought Snow Leopard later. All I want, though, is for other drive to be able to run iTunes 11 for synching to my iPhone occasionally.  I want to keep using iTunes 10.7 as my #1 iTunes on my main drive, which 10.6.8. 


    Wonder if 10.5 will run iTunes 11, or if it will let me upgrade using my Snow Leopard disc....
