I bought two new mac minis (2012). My Promise Pegasus R4 does not recognize the device in both. In old mac mini everything works normally.

Mac mini, OS X Mountain Lion (10.8.2)

    Hi, what Interface does that use?

    Is it ThunderBolt cabled?


    Is it before any Monitor in the chain?

    Hmmm, does it show up In Disk Utility?

    Sorry we're not making any headway on this.


    Open Console in Utilities & see if there are any clues or repeating messages when trying to open the Promise Utility.

    With everything connected, open System Information


    Applications->Utilites->System Information


    On the side bar expand the Hardware label if

    it is not already expanded and click on Thunderbolt.


    Does the R4 show up there when it is connected?

    Is there anything displayed at all?

    It seems the Mini sees something but is getting no clue

    as to what it is which is where the problem seems to be.


    BTW, forgot to ask if both old and new Minis running same

    OSX version?  Also, is the R4 running the latest firmware

    version?  Also, how is the R4 configured?  Do the new Minis

    have all the latest OSX and firmware patches?
