    Can you post your specs? Is this the model with nVidia GPU or integrated Intel graphics? What do you mean by "newest AppleHDA"? You should only use a patched kext of same or lower version than the vanilla kext of your installed OS X version. Don't go install the kext from El Capitan in Yosemite for instance. 1st ensure you run the latest Yosemite or El Capitan versions (with all version updates, including Security ones), then patch the AppleHDA kext or replace your vanilla kext by a pre-patched one.

    Please READ my previous answer.

    Integrated graphics of Optiplex 745 is GMA3000 and that's totally unsupported under OS X. With a 10s Google search, you'd get this: https://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf You have no choice but add a supported PCIe x16 graphics card if you want to run OS X on that type of desktop computer. That rules out Ultra Small Form Factor model. The Yosemite pack should be the same as the Mavericks one. If it runs Mavericks, it'll also run Yosemite and El Capitan. Sierra will not run on that E6400 CPU, it needs a SSE4-capable model. There are plenty of threads related to the Optiplex 745 in the Dell->Desktop section of the forum.

    So you're talking about CPU utilisation, not CPU speed, right? What does your Activity Monitor show? did you install something that could always run in the background and grab CPU ? Which OS X version are you running by the way?
  5. Hervé
    What is it you're after exactly? If you don't want your CPU to run without Turbo modes (i.e. slower) when laptop is on battery, remove the Turbo disabler kext, then rebuild your cache. For the rest, I assume that you've generated your own CPU-specific SSDT using the well-known SSDT generator from Pike R Alpha and that your system runs with proper CPU power management/speedstep.

    Make sure you disable SIP and use this PS2 controller or this one.

    Finally got round to implement the HPET fix in DSDT to avoid loss of USB functionality rather than systematically remove the HPET kext. It's a simple matter of removing the IRQs as detailed by Slice (and others) for instance: Before: Device (HPET) { [...] Name (BUF0, ResourceTemplate () { Memory32Fixed (ReadWrite, 0xFED00000, // Address Base 0x00000400, // Address Length _Y0F) }) [...] After: Device (HPET) { [...] Name (BUF0, ResourceTemplate () { IRQNoFlags () // Excludes IRQs 0, 8 and 11 to prevent loss of USB ports {0,8,11} Memory32Fixed (ReadWrite, 0xFED00000, // Address Base 0x00000400, // Address Length _Y0F) }) [...]

    Are you running with the Turbo disabler kext?
  9. Hervé
    Seems you're booting the recovery partition... Maybe you need to rebuild your USB installer.

    There never was any fix to the black screen issue, if waking the screen from screen sleep. The only workaround is to put the laptop to sleep and wake it. As such, it's best to configure the same timing for Display Sleep and Computer Sleep in the Energy Savings PrefPane. The system password was a requirement for GMA950 systems and does not apply to nVidia models. The D620 NV does not normally have an issue of KP on wake. Mine certainly does not.

    You can look at my research on the matter in the R&D->Graphics section. It was done for my Haswell laptop but the principles remain the same. You need to identify your DP port through an IOReg browser (IORegistryExplorer, IOJones), then experiment with binary modifications of your relevant layout-id section in the BDW framebuffer.

    For the HDMI audio patch, all that's required is to modify the HDMI output connector-type from its default value of 00 04 00 00 to 00 08 00 00. This patch is applicable to all systems whatever the frameBuffer (SNB, Capri, Azul, BDW, etc.) and for all versions of OS X. So, you need to identify the HDMI port line in your particular layout-id of the Broadwell framebuffer (kext BDW FB) and then apply the binary patch; this can be done "on-the-fly" through Clover or through direct binmod of the FB binary file itself.
  13. Hervé
    HDMI audio is handled through AppleHDA (patched for your own codec) + Intel framebuffer (patched BDW FB in your case).

    By 2016, everyone who's done a minimum research should know that no Intel wireless card is supported under OS X. It's even mentioned in the FAQ section: https://osxlatitude.com/index.php?/topic/8696-is-my-wireless-card-compatible-with-os-x/ Please use the forum Search facility before posting.

    A change to the SMBIOS profile may help, like a little jiggle of the production week n° or year to generate a different serial n°. Assuming the SMBIOS chosen model is right...
  16. Hervé
    The only 10.11.3 you could download would be the Combo update. And that would only install on an earlier 10.11-10.11.2 build. Apple only provides the latest version for installation package download. Oh and, no, 10.11.3 would not work better than 10.11.4+ on that system. Maybe you should make a new installation...

    Does it boot if you limit your CPU to 1 core (eg: option cpus=1 in Chameleon/Enoch)?
  18. Hervé
    Means the cache was not rebuilt. Re-type the last 2 commands or use the following alternative command for kextcache: sudo kextcache system-prelinked-kernel
  19. Hervé
    Updated with 10.11.6 files.

    Is your Ethernet interface set to en0? That's mandatory.
  21. Hervé
    Looking ok. But if you keep getting "wrong password", then you're not entering the right one...
  22. Hervé
    FaceTime, like AppStore, should only require Ethernet to be up & running as en0. The other stuff is for iMessage.
  23. Hervé
    Yes, you need to copy the EFI folder to the EFI partition. You can mount it with Clover Configurator.
  24. Hervé
    Reset your BIOS to factory settings, then set AHCI on and disable Optimus.
