Hi all,

I am trying to instal 10.6 Snow Leopard onto my 2011 Macbook Air (Lion native). I have followed many of the instructions listed in related posts, but cannot get the MBAir to boot from the Snow Leopard disc. I have created a USB install disc and it shows when starting up holding the option key. I select it as the boot device and the machine just sits at the gray screen with Apple logo for hours. I did read there could be a firmware issue that won't allow it to boot from a Snow Leopard disc, but I really need to have Snow Leopard cos of the Rosetta support. I tried the install disc with a USB disc drive and got the same result.

 

Any and all input most welcome

Thanks in advance

    Update it to Mac OS X 10.6.8 if it's not already running that OS version. If it already is, not without running Mac OS X Server in emulation.

    if it came with Lion installed you cannot get it to boot Snow Leopard.

     

    Your only option is to install Snow Leopard Server into a virtualization program such as Parallels 8:

    Apple is now selling Snow Leopard Server for $19.99 + sales tax & shipping costs at 1.800.MYAPPLE (1.800.692.7753) - Apple Part Number: MC588Z/A (telephone orders only).

    Your suggestion, which I am sure was well intentioned, is completely unplausable.

    Read this thread on how to install Snow Leopard on the "new" 2011 Mac Mini...

    When I was young, I used to have a sign on my desk that read:

     

    "I CAN do the impossible; just not in 24 hours!"

     

    In those days, I was the first one to upgrade the OS and experiment with everything.

     

    Now: not so much!
