The Mac mini is delivered with 10.7, but is it also possible to install 10.6 to keep old applications running?

MacBook Pro, Mac mini,, Mac OS X (10.6.4)

    Mac's never let you install an OS earlier than the one it comes with.

    ...And what is the reason do you need for the Mac mini specific drivers? ...

    It's model specific drivers.  Older versions of OSX may not include drivers for newer hardware, and so could cause issues with the first time you boot, even from a "pre-loaded" hard drive.  There may be ways to install after the fact, but of course, this is not supported by Apple.  Thus the general statement that you can only use a version of OSX the same or newer than what came with the computer originally.

     

    IOW, maybe you can boot from a pre-loaded drive.  Sometimes you can't without some additional work.  Sometimes you can't at all.  Since it's not supported by Apple, future updates to OSX won't be tested in those configurations.  So some future update may "break" your computer.  No guarantees.

    The firmware prevents it.

    " I think the information that 10.6 will not official run on the new Mac mini will prevent a lot of professional people to buy this mini."

     

    Why on earth would you want to buy a new machine with a more capable OS and downgrade it to a less capable OS ?

     

    Beyond just knowing that you can, what would be the point?

    Easiest way to install 10.6 will be to do so via an early copy Snow Leopard DVD (try ebay) - obviously you'll need to connect a superdrive (or another disc drive) and then boot with the DVD in whilst hitting the alt key. I would do an erase and install (personal preference) so load disk utilities before installing SL proper, and reformat your MacMini HDD.

     

    Before doing this though I would clone your existing hard drive on your mini using Carbon Copy Cloner or Superduper! so you can always go back to your current set up if required.

    >It seems to be, that the firmware didn't prevent it. Someone has started the new mini from a target mode booted MacBook. In the first test everything wars running without problems.

     

    I guess when mine shows up next week I'll have to give it a try, just for grins.

    At this moment in time, the question comes up because Lion removed Rosetta, which allowed you to run PPC apps.  Developers "should" have been moving their apps to be Intel native, but some professionals may have expensive apps that would be financially difficult to purchase a newer version.  Or the vendor didn't bother to update to Intel native.  The biggest offender is Intuit with Quicken 2007 for Mac, which is PPC only.  Intuit now has Quicken Essentials, which will run on Lion, but from all reports is quite a bit less capable than Quicken 2007.  So many Quicken users that stayed with Quicken 2007 are scrambling to try to find a replacement.

     

    The same questions were asked when Classic was removed from OSX.  (Classic allowed you to run pre OSX apps.)

    Rosetta is available as an option in the Lion installer or can be downloaded automatically if required.

    Did you mean less capable OS and downgrade to a more capable OS???

    Rosetta is not available in 10.7.  It was dropped.  Trying to open a PPC application in Lion will yield the following message "You can't open the application ApplicationName because PowerPC applications are no longer supported"

     

    And it is not an option on the Customize screen in the Lion Installer

    There are plenty of reasons to run a new MacMini with 10.6.8.  I'd imagine it will run fine as the Thunderbolt and SandyBridge kernel extensions are all in the 10.6.8 combo update.  You would need a 10.6.8 install DVD, firewire clone to it or deploy a 10.6.8 image to it.

    It is possible and a perfect way to use this excellent machine to run software made from 2001-2013:

    You need:

    - A Snow Leopard Retail disk (with the kitten up front), 10.6.3 preferably.

    - A firewire cable

    - A Mac running Snow Leopard

    - Some files of the Lion install and save them on a USB stick for use in SL

    Here is a small manual (dutch) retreived from the 35 pages of the topic above:

    Robot translation that seems quite readable
