It would be interesting for you to boot up this new MBPi7 into the OS X version that came with it. Either the pre-installed HD, booting of a HD a system from a clean install off the Installer CD/DVD that came with the MBPi7, or off the Installer CD/DVD - in order of preference - and looking at it's build id. If you Apple Menu -> About This Mac -> Version number in dialog, it will reveal the Build. It is very doubtful that it is your app kext, and you could simple boot into Safe Mode (see support.apple.com/kb/HT1564 and support.apple.com/kb/ht1455) which would not load such kexts. Most likely, in what has been alluded to but not fully explained, the OS build is lower than that required for your machine, your missing machine profiles for the new hardware, or kexts necessary for new hardware. As Apple releases new machines they release them with system builds and file distributions that support them. Older system builds would effectively mean that the older system kernel doesn't support your hardware. In addition machine profiles abstract hardware and are necessary to support new models. They're released with the new hardware normally before we would see them in the next bootable release that Apple produces. This is always the 10.X.0 version and we see some full/box bootable updates over time, but these releases (as opposed to OS updates) number two or three for any Mac OS X version. Sometimes updates will later include them. Likewise any new hardware kexts that are required also probably aren't on your older machine's system volume. We often see these when we have new classes of video controllers, and new system architectures. The MBPi7 certainly has variants of each of these differences. -d ------------------------------------------------------------------------ Dan Shoop Computer Scientist [email protected] GoogleVoice: 1-646-402-5293 aim: iWiring twitter: @colonelmode _______________________________________________ MacOSX-admin mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-admin
