I've had a look at the install SL on a a mac mini thread and I'm still a bit confused about what my options are in a current imac. I spoke to an apple tech guy today and he said I'd need 10.6.3 but I've since found that that info is not correct anyway.

 

The iMac in question was manufactured a month ago and came with Lion. I'd like to run it with 10.6.8

 

I can't purchase as a digital download any longer only a posted disk.

 

The thing is will it be 10.6.8 if I get it from the apple store in Australia, and will it run on a current model iMac 3.4GHz, I don't want to pay $35 for a coaster.

 

thanks.

iMac (27-inch Mid 2011), Mac OS X (10.7.3)

    You cannot install an earlier version of OS X than the one it shipped with.

    I also would like to replace 10.7 with 10.6 on an iMac. I was told by Apple Help that it was not possible to do this but I could partition the HD and install 10.6 on the partition. Later was told by another tech that this was not possible. Who is right? I would also like to partition a Powerbook HD and load 10.4 on one part and 10.5 on the other. Is this also impossible? What has happened to "customer friendly" Apple?

     

    Thanks

    There is no legitimate place you can download Snow Leopard. The only way to get it is by buy it on DVD. Most of the DVD that are available are to old for what you what to do.

     

    Why do you think you need Snow Leopard?

    I purchased an installation disc from Apple. I don't need Snow leopard but I don't like Lion; May come to like it but don't now, and the disc cost me $30.

    An install disc from another machine will not works on yours, nor will an older OS allow itself to br installed over a new one.

    Klaus is absolutely correct!

    The basic problem is that if your machine is new enough in its hardware to have shipped with Lion, then erasing Lion and installing an earlier OS will be problematic.  That earlier OS will NOT have the necessary drivers and firmware installed for your Newer iMac's hardware.  Thus instability in operation.

     

    Hope this helps

    It is possible but if it would actually be capable of booting the iMac or not depends on the specific iMac model & when it was manufactured. As Radiation Mac explained, unless the 10.6 disc includes the necessary drivers to support the hardware of that particular iMac, it won't work.

     

    What has happened to "customer friendly" Apple?

    Basically, Apple hasn't found a way to go back in time & add drivers for future hardware to preexisting installer DVD's. That applies to any model or OS version.
