For reasons that have been expressed very often on this forum (primarily Rosetta and the ablitity to run PPC-apps) many people have been asking me to put together in one place the results of my research on this topic.  I have taken all of the research that I have found, and refined and improved much of it.


This thread, as Part One, will look at the long process for completing this result; the so-called "not easily accomplished in three steps" process.  It will be followed later by my and hopefully others, suggestions for the "easy" way. 


Why the long process first?


•  Some people appreciate being able to roll up there sleeves, do it yourself and achieve the satisfaction that comes from successful completion of the project;


•  Just like I have made improvements to what I found in my research, I expect others will offer improvements to what I have to offer; and


•  If the "easy" way is offered first, there will be little encouragement to improve the long process.


What is needed:


•  Installation of Parallels 7 in your Lion computer - I will expect this step has already been completed.


•  A fresh copy of the Snow Leopard Installation DVD (and not a machine specific, nor restore disk that may have come with your computer).


•  Use of the programs Disk Utility and Terminal, both of which are in the /Applications/Utitities/ folder.


What are the steps that will be taken:


1.  Preparation of the Snow Leopard Installation DVD for use in Parallels 7


2.  Installation of Snow Leopard into Parallels 7 (and optionally installing Parallel Tools)


3.  Upgrading Snow Leopard to 10.6.8 and other available upgrades


4.  Creating a backup of the completed process.


I will be offering each step, one at a time...

    Agreed, and it also is unsupported by both Apple and virtualization tools (parallels, vmware, etc.), so while it might be a fun hobby to get going, I would not rely on it as a solution for day to day productivity. The best solution here is to either avoid upgrading if you still need Rosetta or similar tools that Snow Leopard offers, or update your applications to work with the new OS (for most there should be an updated option).

    Good work, thanks!

    Great job, Michael! Thank you for this!


    In addition, if appropriate, could you please provide some of your research links? While I understand most of the steps, I would like to be able to understand all of them and read more about the techniques utilized.


    Initially, I installed Snow Leopard in Parallels using the guide (and your comments) from:



    which you mentioned in your post:



    in reply to my question on:



    While I stumbled upon that guide before finding your posts, they were immensely helpful in steering me in the right direction. Thank you for that. However, while Snow Leopard in Parallels is finally running, I have experienced a few issues and posted them on the guide's website:

  e-part-two/ ox-guest-os/


    Now, I have not yet tried the method you posted here, so I don't know if it resolves those issues, but I am eager to try it to find out. I haven't seen any replies to my questions and I anticipate it will be awhile before anyone responds (last posts there were in November 2011), so if you could share your ideas about the issues I encountered, I would very much appreciate it. I imagine it would be best to do so on that website, but if starting a new discussion on ASC is more appropriate, I am all for it.


    Again, thanks for all the hard work that you put into this guide! I look forward to the next installment.

    This doubt may sound a little dumb but I'm such a noob in these subjects, are all these steps able to do in a computer that came with lion from factory? 'cause i had been looking for downgrading my OS in order to use apps like Logic 8 (and so on...) but the answers i found differ in this: so if you had a computer that came with snow leopard in the beginning and you upgraded to lion you can downgrade to snow leopard again, but if you have a computer that came with the lion OS from factory there's no possible way to downgrade to snow leopard. That's the reason of my question 'cause i don't want to waste any money purchasing the snow leopard dvd in order to make the partition you're talking about if it's not going to work.


    Thank you very much in advance, please answer as soon as you can!
