EC Patching – Coping with AppleACPIEC on a Catalina Hackintosh


An EFI folder that might boot macOS Mojave can’t crucial boot macOS Catalina attributable to modifications in the way in which AppleACPIEC behaves which require it to be both disabled, renamed or spoofed in addition macOS Catalina on most hackintosh motherboards. Not addressing EC in Catalina could cause hagging with verbose outputs corresponding to Ready on root machine… or AE_NOT_FOUND that can stop you from booting Catalina.

Hackintosh Catalina EC Patching

  • The choice to disable AppleACPIEC presently has points and is just for these utilizing the OpenCore technique of hackintoshing and never Clover, leaving us with the choice to faux or rename our EC machine which is required .for AppleBusPower to perform.
  • Renaming EC – Advisable for laptop computer use as this nonetheless masses AppleACPIEC which isn’t used or appropriate with a desktop however nonetheless works.
  • Faking EC is finished turning off the true EC one and setting a faux one up by putting a patched SSDT-EC.aml file in EFI/CLOVER/ACPI/patched.
    • Advisable by the group for desktops, don’t use for laptops.
    • The draw back to this technique is when you change the {hardware} in your system i.e. swapping out the motherboard or laptop making an attempt to get the Catalina installer to load. The SSDT will have to be remade for a particular machines {hardware} earlier than having the ability to boot whereas the precise rename patch tends to be comparable throughout motherboard generations i.e. a Gigabyte Z370 motherboard and an ASUS Z390 motherboard could have the identical EC rename. In that case beginning with the rename technique is likely to be a greater answer to begin with.

To do both repair you’ll wish to generate a DSDT:

  1. Generate a DSDT desk by restarting laptop and getting into Clover Bootloader
  2. Press F4 will trigger a DSDT to be generated and positioned in EFI/CLOVER/ACPI/origin
  3. Reboot again into macOS and Mount EFI partition
#1 Renaming EC Technique
  • Renaming EC provides a easy Hex patch below Acpi -> Patches of config.plist from this desk:
    Remark Discover* [HEX] Exchange [HEX]
    change EC0 to EC 4543305f 45435f5f
    change H_EC to EC 485f4543 45435f5f
    change ECDV to EC 45434456 45435f5f
  • Just one of those three patches is used at a time. DO NOT allow a number of on the identical time or you could not be capable of boot
  • To search out out which patch is appropriate for you’re laptop can both guess by including separately and making an attempt in addition Catalina or you may merely examine the DSDT you generated by following steps 1-6:
    1. Obtain MaciASL
    2. Open EFI/CLOVER/ACPI/origin/
    3. Open DSDT.aml with MaciASL
    4. Use ⌘F to open the Discover search bar
    5. Seek for PNP0C09 will probably be in a bracketed below a tool named Gadget (EC0) or Gadget (H_EC) or Gadget (ECDV)
    6. Some computer systems will return two machine outcomes for PNP0C09 to search out out which is the right machine it should include an _HID, _CRS and _GPE in its brackets for instance:
      • (_HID, EisaId ("PNP0C09")) // _HID: {Hardware} ID
      • Identify (_CRS, ResourceTemplate () // _CRS: Present Useful resource Settings
      • Identify (_GPE, 0x16) // _GPE: Common Goal Occasions

        Finding EC for Hackintosh Catalina EC Renaming

        On this instance EC0 is the right EC because it comprises a _HID, _CRS and _GPE worth, subsequently the patch used will probably be rename EC0 to EC

    7. As soon as you determine what patch you want from the desk add it by opening config.plist with Clover Configurator and putting the patch below Acpi Patches:
      ACPI Patches Empty

      In case you are utilizing the EFI from I’ve included the patches in config.plist already nonetheless they’re all disabled by default allow the one that’s best for you by unchecking disabled.

      Right here’s the desk once more:

      Remark Discover* [HEX] Exchange [HEX]
      change EC0 to EC 4543305f 45435f5f
      change H_EC to EC 485f4543 45435f5f
      change ECDV to EC 45434456 45435f5f
#2 Faking EC Technique
  1. Obtain SSDT-Time and unzip the folder
    1. Learn the directions
  2. Open SSDTTime-master folder
  3. Proper-click open SSDTTime.command
  4. It will open Terminal
  5. Please choose: 2
  6. Drag and drop a DSDT.aml or origin folderSSDTTime.command SSDT-EC creation Terminal
  7. SSDTTime will routinely open a Outcomes folder
  8. Copy SSDT-EC.aml from the Outcomes folder and place it in EFI/CLOVER/ACPI/patched
    • Observe: The patched folder not the origins folder
    • You probably have any points getting SSDTTime to work use the rename technique as a substitute.
