Q: Partition HD to run Yosemite and Snow Leopard

HI, I own a 2009 iMac currently running latest version of Yosemite.  Unfortunately, I have an older version of protools express, which will only work (it would seem) on older OS version.  From investigations,  Snow Leopard will do the job

 

i have partitioned my HD to 2 sections (renaming the new section appropriately) so I can install Snow Leopard, however when I reboot (holding the option key) I cannot see the newly created partition.  only the existing Mac HD with Yosemite and another HD labelled Mac Recovery 10.10.3??

 

what am I getting wrong?? Is it possible to do what I'm hoping? Or is there an easier way to go about running Snow Leopard so I can use my Protools software?

 

first time using Apple Support so apologies if I'm not giving enough info...

 

thanks heaps

iMac, OS X Yosemite (10.10.3)

A:

If you boot from the Snow Leopard CD/DVD you will have the option of using the Disk Utility from before the install.

Select Disk Utility from Utilities.

You can reformat or repartition from there but you want to avoid changing anything on your Yosemite volume which could be disastrous.

    Try this experiment. Go to the

     

         Apple Menu > System Preferences ... > Startup Disk

     

    preferences panel. Can you see the Snow Leopard partition there? If you select it and restart, does the machine restart in Snow Leopard?

    That means it is not being recognised as a disk with a bootable system on it. As you can see from the screenshot below taken on a 2010 iMac what you are attempting should be possible. I would try reinstalling Snow Leopard on the partition you want it to be on at this point.

     

    If that doesn't work, open Utilities > Terminal.app, type this command:

     

         diskutil list

     

    and report what it says back here. I've pasted the results from the same machine below the screenshot.

    Maybe someone else can chime in on whether Core Storage is the problem here. I would try this: clone the HD to a backup drive, verify that it is bootable and working, and then proceed as JimmyCMPIT suggests, so that the drive is formatted and partitioned by Snow Leopard's version of disk utility. Install Snow Leopard on one partition and then clone back the Yosemite volume to the other partition.

    Thanks Heaps.. I got it sorted!

     

    In the end it was as simple as booting up from the snow leopard install disk!  And then choosing my partitioned drive..

     

    Simple!

     

    Appreciated

    Hi,

     

    I´ve got the same problem on my MacPro (late 2009) now running Yosemite. An older version of Final Cut Pro 7 only runs with Leopard so I have to reinstall, hopefully on an internal partition...but the way described didn´t work for me, any suggestions?
