    since your first advice a month ago everything works fine mith my i7 Mini and SnowLeopard,

    Thanks for your continious work!

     

    Why is your Level still 1 (0 points)? It should grow!

    CORRECTION, should be 755:

    Oh, install instructions:

     

    1. Download and extact each kext

    2. Go to /System/Library/Extensions and delete the existing AppleIntelHDGraphics and AppleIntelSNBGraphicsFB (eg. move to trash)

    3. Copy the ones you extracted into /System/Library/Extensions (you might get a warning after kextcache kicks in automatically, ignore this)

    4.  Using terminal do:

    sudo su -

    cd /Sys*/Lib*/Ext*

    chown -R root:wheel AppleIntelHDGraphics.kext

    chown -R root:wheel AppleIntelSNBGraphicsFB.kext

    chmod -R 755 AppleIntelHDGraphics.kext

    chmod -R 755 AppleIntelSNBGraphicsFB.kext

    kextcache -system-prelinked-kernel

    kextcache -system-caches

     

    (then restart the mac)

     

    Second display should be gone, and version of those kexts should be 1.6.42

    Unfortunately I copied and pasted from another post

    My Mini seems to work fine after all the instructions above, Thanks  a lot !!

    but when i run

    "kextcache -system-prelinked-kernel"

     

    i got this message..

     

    kext doesn't support architecture x86_64; omitting from prelinked kernel.

     

    is that bad?, it seems to work fine anyway.

    /System/Library/Extensions/IOSerialFamily.kext/Contents/PlugIns/InternalModemSup port.kext doesn't support architecture x86_64; omitting from prelinked kernel.

     

    InternalModemSupport.kext isnt 64-bit compatible, and so is always automatically omitted.

    Thanks NewFoundGlory!! - That did the trick.

     

    Thank you so much this is really a releif.  Lion did not work as server for me. Now after 2 month the new MacMini can do som real work.

     

    No more second display, no mouse problem, dual display output is working, HDMI output can be disconnected and reconnedted withtout problems, video playback is silky smooth, geekbench is good and cinebench runs good.

     

    Seems everything is the way it should be: New quad MacMini with Snow Leopard.

     

    Say, NFG, what mac where those kexts distributed with?

     

     

    Best wishes,

    Kasper

    Thank you so much ! Those 2 kexts were the final thing I needed to get my 30 inch ACD working on my Mac mini server ! It was already running fine without them on my 2,5 gHz i5 mini...

     

    I did had some difficulty to get them to work. When I tried to change the ownership to wheel, when I did the kextcache thing, I got the error that the IOPlatform extension was suspiscious, and was unable to prelink them. ( or something like that, don't remeber the actual error ).

     

    Than I made a root account, logged in on that one, and was able to change the ownership and to run the kextcache rule.

     

    Now it is working fine.

    I wonder whether it would not be easier to clone a SL 10.6.8 partition unto a partition in a new generation mini. I have just purchased a i5 one.

    Give it a shot and report back.

    27" i7 iMac 10.6.8 , Mac OS X (10.7.2), G4 450 MP 1.5 GB RAM w/(10.5.8/10.4.11/9.2.2)

    I will, not today but for sure these days. An i5 cannot be so new, must essentially be the 2011 generation even if with Lion preinstalled.

    I guess you didn't read the whioe topic... ;-) Cloning a already updated partition was the first thing we tried...

    The first thing I did with my new Mini (i7) was to use a clone of my 2010 MIni with 10.6.8 to see if it works.

    It (slowly) did.

    Then I tried several things, even a clean installation in Firewire-Target-Modus, this works (slowly) too.

    When I saw NewFoundGlory solution I used my Macbook pro (2009) with 10.6.8 for a clone, used the Resources as described and everything was fine.

     

    If you plan to use the same applications, to clone is the easiest way!

    My method was:

     

    * I've booted the macmini in target mode and connected to a Pc via Firewire.

    * Booted a hackintosh (it might be done with a real mac) with the 10.6.0 original SL disk inserted.
    * Installed the 10.6.0 in the macmini HD -> no hangs, no reboot.

    * rebooted the hackintosh normally with the macmini still connected in target mode.

    * Update the macmini to 10.6.8 (combo).

    * Installed the video kexts

     

    All done!

    My experience:

     

    1) Installed 10.6.6 that came with a 2011 MBP 15" on the Mac Mini Server using it on target disk mode. I'm actually doing this on a RAID-0 array I've created on the Mini (which means I erased the factory Lion partition...)

     

    2) Updated to 10.6.8 at first reboot, still on the MBP

     

    3) Rebooted the Mini by itself. Graphic glitches, phantom display, mouse issues.

     

    4) Fixed this using the kext files method discovered by newfoundglory (cheers dude!) and the files downloaded from megaupload

     

     

    So far, no apparent issues. I have not, however, tested the thunderbolt port, graphics acceleration or resolutions above 1080p

     

    From what I've read on this thread, I've noticed that I'm supposed to copy some .plist files to the Mini. I don't know exactly what these files will fix (CPU issues?). Although I have a Lion install disc, I can't find these files inside the mentioned kext. I'm guessing I'll have to actually install Lion on some other disk, because the kext on the install disc (ACPI_SMC_PlatformPlugin.kext) does not contain the plist files ≈

     

    ...or perhaps someone can share the plist files?

     

    Anyway... conclusion: SUCCESS, apparently. Thanks a bunch to everyone involved in the process, and special greets to newfoundglory.
