    Can I transfer all my PowerPC applications from a lion partition to OS Snow

  • John Springate Level 1 Level 1 (45 points)

    This thread has been a great help to me as I have cubase music software and some of the older synths do not work beyond Leopard so it would be great to get them back again. So that Im absolutely sure I know what Im doing can some one tell me if when I make a partition it wont erase whats already there my hard drive? It will simply give me the partition size I need to put leopard on? I have got time machine installed so I do have a back-up of the hardrive in question.

    PS I have an imac i7 with 12gb RAM

    If you follow the steps I have previously described, you should have no problem. When you create the partition, it won't let you size it so that it will erase any existing files. You can then insert the Snow Leopard disc that came with your computer, reboot, and the last question before it starts to install is to ask which partition do you want to install in.

  • lzrdoc1 Level 1 Level 1 (0 points)

    I am not at my computer now, but when you boot using Lion, there should be both the Lion and Snow Leopard hard drive partition icons on the desktop. I would anticipate that you should be able to cut and paste between the two. I have copied applications from another computer onto a flash drive and pasted them into Snow Leopard with no problems.

    As posted by an earlier user (Robin Lewis), I can't install from the Snow Leopard install disc (that I purchased when it was released).  I've created a partition.  When I hold "C" when rebooting and select the SL Install DVD the screen goes white and locks up.  Nothing else appears.  Any suggestions?

  • lzrdoc1 Level 1 Level 1 (0 points)

    It is my understanding that you have to use the install disc that came with you computer. If it was Leopard, you will have to install that first, then upgrade to Snow Leopard as you normally would. You also do not have to hold the "Control C" ... just put the original disc in, and it will take you from there.

    Thanks for posting this, I hadn't thought of the partition option. I was looking at erasing whole drive and starting from scratch with snow leopard, ugh.

    I have been trying this so I can run Pro Tools again.  But when I try to log in to my newly installed Snow Leopard (installed from my original disk) it asks for my system password.  Problem is that it wont accept the proper password. 

    So I cant even get into Snow Leopard...

  • ndroste Level 1 Level 1 (0 points)

    Yep, pro tools is why I need SL as well. I've since discovered I can't have a third boot partition on my MBP hard drive (I already have bootcamp and Lion on there) so I installed snow leapoard on an external firewire 800 drive, purely for pro tools. It's basically a role reversal, I've got the OS and pro tools on the FW drive and will use the MBP's built in drive and the scratch for media files. It's working so far, hopefully until they make Pro Tools lion compatible. Good luck.

    I have my original install disc from 2009. And snow leopard. If I put in the sl and reboot the sl partition doesn't come up as a choice even though it's in the disc utility & desk top. I went to the preferece start up disc & it's not there. What am I missing here?

  • tammotsie1 Level 1 Level 1 (0 points)

    Got it. Put snow leopard in. Restart hold down C until install starts. Continue until it asks which partition and it shows up!!!  The only way the new partition would show it's self.  Now loading.

    But this wont help if Snow Leopard wont even accept the proper system password.

    Installing Snow Leopard in a Lion Partition.


    This looks to be really helpful for me as I have a Cisco client that will not work in Lion. I am fairly new to Macs and your instructions seem exceptionally clear thank you. Am I correct in assuming that you would need to switch between OS in Preferences depending on which you wish to use? Also am I correct in saying that all my resources Word etc etc would be available in Snow Leopard as well as Lion?

    Many thanks

  • lzrdoc1 Level 1 Level 1 (0 points)

    You are correct. To switch, you need to reboot in that partition. To switch between partititions, you go to "Preferences", and to "Start Disk". Click on this, and it will give you the option as to which partition you wish to boot up.

    As to your resources, I used Migration Assistant to bring information from my Lion partition to Snow Leopard. This did not bring the programs over. Only the applications that are intrinsic to Snow Leopard are there. So you may have to reinstall the ones that you want. I backed everything up to a hard disk, so I can copy some of the programs from that, but others have to be reinstalled in the new partititon. I have opted to only install the applications that do not run in Lion, but I can see that having some basic utility programs such as Word could be useful.

  • lzrdoc1 Level 1 Level 1 (0 points)

    I found that I had to first install Leopard using the OS disk that came with the computer. Once that was installed, I could then install Snow Leopard. A bit of a nuisance, but it works well. As I commented in my reply to

    Carey_from_Haverfordwest, only the applications that are part of Leopard or Snow Leopard are installed, so you will have to re-install the applications that you want to use in that partititon.
