    DSDT for MSI B75MA-P45


    For BIOS version 1.0: DSDT-MSI-B75MA-P45-V1.0.aml.zip

    Tested with Lion 10.7.4 and Mountain Lion 10.8.

    1. Onboard Graphics: working.
    2. Audio: working with patched AppleHDA for ALC888b/887 v100302 from Multibeast 4.6.1.
    3. LAN: working with Lnx2mac driver.
    4. Sleep: working.
    5. USB 3.0 ports:
      • working under Lion at USB 2.0 speed with PXHCD.kext.
      • under ML system hangs when any device is plugged into an USB 3.0 port.


    For BIOS version 1.2: DSDT-MSI-B75MA-P45-V1.2c.aml.zip

    Tested with Mountain Lion 10.8.

    1. Onboard Graphics: working.
    2. Audio: working with patched AppleHDA for ALC888b/887 v100302 from Multibeast 4.6.1.
    3. LAN: working with Lnx2mac driver.
    4. Sleep: working.
    5. USB 3.0 ports:
      • low speed devices: working unstable because sometimes the USB subsystem freezes when a low speed device gets removed from an USB 3.0 port. Try to avoid them.
      • full speed devices: working stable.
      • high speed devices: not working.
      • super speed devices: working stable.
      • Note: The bug which caused the system to hang when any device was plugged into an USB 3.0 port is fixed since version DSDT-MSI-B75MA-P45-V1.2b.aml.


    For BIOS version 1.4: DSDT-MSI-B75MA-P45-V1.4c.aml.zip

    Tested with Mountain Lion 10.8.2.

    1. Onboard Graphics: working.
    2. Audio: working with patched AppleHDA for ALC888b/887 v100302 from Multibeast 5.2 (layout-id 2).
    3. LAN: working with Lnx2mac driver.
    4. Sleep: working.
    5. USB 3.0 ports:
      • low speed devices: untested.
      • full speed devices: working stable.
      • high speed devices: working stable.
      • super speed devices: working stable.

    DSDT for MSI B75MA-P45


    There is a new BIOS 1.4 since October 25th, has anyone tried it? Does it fix the USB 2.0 issue? Is there a new DSDT available?
    Thanks.

    Hey Lorphos,

    I just patched BIOS 1.4 and installed it on my machine. Although the DSDT from version 1.2 works fine, I extracted the new one and will patch it as soon as possible. I will post both, the patched BIOS and the DSDT during the next days.

    As far as I can tell there is no change with regard to the USB 3.0 ports. USB 3.0 devices work well but USB 2.0 devices still refuse to show up when connected to the 3.0 ports.

    DSDT for MSI B75MA-P45


    I managed to get the USB 3.0 ports fully working with USB 2.0 devices by creating a rather complex DSDT patch for BIOS version 1.4 which was inspired by an extracted DSDT from a mid 2012 Macbook Pro. As the patch is far from being trivial it must be considered experimental and needs further testing.

    I wasn't able to test if sleep is working because my machine is running the server version of Mountain Lion 10.8.2 which doesn't sleep anyway.

    Although my system is running stable with the DSDT use it at your own risk and be prepared to recover your installation in case something goes wrong.

    The experimental DSDT is obsolete because I integrated the USB 3.0 patch into the regular Version 1.4 DSDT (see above).

    You should upgrade your BIOS to version 1.4 (I also published a patched version which can be found in the repository). Here is a link to a set of screenshots I took with version 1.2 but for version 1.4 I'm using the same settings: Screenshots

    I just updated the Version 1.4 DSDT. Now the USB 3.0 ports are fully functional even with high speed peripherals.

    Remove AppleIntelFramebufferCapri.kext from the installer drive's directory /S/L/E. If this does‘t help also remove AppleIntelHD3000GraphicsGLDriver.bundle and report back if it resolved the issue. Boot with -f -x in order to ignore kernel cache. In case it hangs please make a photo of the screen and post it here.
