Hi all,

 

due to severe problems [1] with getting NFSv4 to work on Mac OS X 10.8.2 (Mountain Lion), we've thought about downgrading to Mac OS X 10.7.5. When trying to boot from the 10.7 USB stick, our Mac Minis (Late 2012, MacMini6,2) refuse to start up. Therefore my question to the community: Is there any possibility to run the most recent version of Mac OS 10.7 (10.7.5) on the latest model of ther Mac Mini? Is it worth the time to try to install them from a boot device containing all recent updates of 10.7 (which means 10.7.5) or to image their disk from an older Mac Mini (Mid 2011, MacMini5,2)?

 

Thank you very much for any help in advance!

 

Kind regards,

Steffen

 

 

[1] We use Oracle Solaris 11 as our NFSv4 server together with MIT Kerberos. While we got our Macs to act as NFSv4 clients, the NFS access is awfully slow which means that a simple "ls" in a NFS directory with about 10 elements takes for about 10 to 20 seconds. Quite the same problem with 10.8.x has been described here in more detail: https://www.illumos.org/issues/3368 a few months ago.

    No, it's not.

    The Mac Mini comes pre-installed with OS X that is specific to that model. So, a version of OS X (e.g. Lion) purchased from the App Store or from another Mac Mini (e.g. 2011 models) won't run on your 2012. The hardware is different on the 2012 models compared to prior models. You could try to run Lion from an external drive that has a clone from a 2011 model Mac Mini. No guarantee it will work.
