@matgeo, AppleACPIEC may cause problems, but you can't fix them unless you want to have a broken battery status and many other broken things by turning off the ECDV device.

Don't use alexboro's files. What he did was rename some of ECDV to EC__ in DSDT and left the rest of the DSDT unchanged and completely ignored SSDT-8 and SSDT-9. It will cause a boot failure. I gave you the alternative to his half done patch, and it worked. But you may want to keep following this thread because maybe you did not need any patch at all.

I think that guides for power management should be revised.

 

The goal is to prevent AppleACPIEC for loading.

For my laptop AppleACPIEC is loaded under ECDV. If I rename it to EC then it loads under EC.

 

With ssdt-ec it adds a fake EC device with nothing injected. AppleACPIEC still loads under ECDV and I have an additional EC device which does nothing.

 

Maybe the solution is to disable ECDV with a patch and then add a EC device.

 

Can you help me compil such a patch?

Here is very interesting script that might resolve your EC issues. Unzip and run command.

Seems interesting but I'm getting error : /Users/mathewg/Downloads/SSDTTime-master/SSDTTime.command: command not found

You asked for a device name EC at first, so I told you what I currently know.

That's why I said keep following this thread. From 10.12 to old versions of 10.15.bx, an EC device is needed for power injection. Currently since Beta 8(?) EC is not needed I think? I'm downloading the macOS installer image to see on what condition the USB power management is correctly implemented.

Tried in HighSierra and it worked (the script).

 

But my laptop doesn't boot with the ssdt-ec.

Why High Sierra? Check if AppleBusPowerController is loaded anywhere.

@hardcorehenry, interesting stuff. Nothing in the readme though :(

Ok so i did a fresh install of the latest beta (9) i think on my desktop as i couldnt boot after installing the latest IPG (3.6.0). Now i installed IPG and rebooted and it was fine i think but then i installed iCue for my keyboard and mouse and of course it needed a reboot. Upon rebooting it just goes into a boot loop. I think beta 9 is very screwy. Does anyone know how i can download beta 8?

Ok.

 

I keep trying to prevent ECDV(and APPLEACPIEC) from loading and instead adding a fake EC device.

I use a ssdt-ec according to guide but I still have the ECDV device.

What I'm doing wrong ?

Here is my clover folder https://mega.nz/#!vMR0HYCR!I4GXc6ov6-3UW8vWZ7nC0Fh9PihI1HLsUmT3rNFaT6EUntitled.png.0667cf285cba01889cc913ee1cd63d51.png

Google "USB power property injection". This topic is for Catalina, not High Sierra.

And why don't you actually read what's in the SSDT? You don't seem to know what you are doing.

@matgeo I told you to search USB power because this discussion started with USB power maangement and I got confused. Still, that guide talks so much about renaming devices. It's helpful.

SSDT-EC.dsl talks about AppleACPIEC in one of the links inside SSDT-EC, and I guess you still haven't looked into it. I don't remember how many times I said look up.

Your IOReg shows High Sierra.

If you go ask for help in OC forums I'm sure experts there will help you. Please keep this topic off of AppleACPIEC. It's a problem in every OS, not just Catalina.

MY problem solved with LCD brightness.  WEG alone does not take care of this for Laptops that have only Nvidia GTX and Intel integrated graphics disabled.  We still need AppleBacklightFixup and WEG alone does not work.  We still need WEG obviously, but whatever code is in ABF needs to be included in WEG for future releases for NVIDIA support.  I was able to get ABF to work again with a bootflag to run on unsupported software such as Beta Catalina so once the final version of Catalina is released it will work without this flag "-applbklbeta hopefully.  We need future release versions of WEG to support exactly what ABF does for Nvidia GFX, and not just Intel.

I haven't noticed any ill effects from loading AppleACPIEC here either. All three of my hacks have been loading it for years. I didn't even look into this until I tried to update my laptop to this latest Catalina build. Without a EC device (even dummy) my USB ports would cut out shortly into boot causing it to hang. Nothing is attaching to it in the IOReg in Catalina but it still can't boot without it.

 

Out of curiosity I tried to block loading AppleACPIEC on my X79 (where I've had EC0 renamed to EC in DSDT) with a SSDT that disabled EC0 and injected a dummy EC device but the system wouldn't boot. Maybe it's more of an issue on newer hardware. Mine is all Sandy/Ivy era.

Did you install fresh or over your current install?  Every time I install over the previous version things go wrong for me something to do with the Data volume, I think I am suppose to boot to that after the initial somewhat short install it boots to install but its the Data Volume, I am guessing that is where the image is initially placed so when I continue from there it seems to complete the second portion reboots but wants to install again from the Data volume where the image was placed so my install keeps looping over and over.  Do I need to remove the Data Volume before proceeding with the install?

 

Is the Beta/Developers preview version in the version.plist?

If you remove the data volume, you will lose your files.

Maybe format only the Catalina Volume leave the Data one alone, I'll try that and install fresh.

 

Ok the update through Settings Update went fine.  Maybe its the full download and update from that installer that I am having a problem with?

 

So its puts the installer onto the Data Volume but does not want to boot to that volume wants to boot back into Catalina without continuing the install.  I have to choose the Data Volume from Clover GUI to continue and complete the installation.

      After a quite smooth running /w Mojave (both Clover, OC build), a few days ago I upgraded to Catalina soon after public release, and I found out DP output to black screen, then I switch to HDMI, it works. When DP goes black screen, unplug then plug the cable, screen comes back then gone.
      After a lot of searches, I found out some simalar cases, but none of them have a solution,
      today I was quite happy to find out this post is https://www.tonymacx86.com/threads/majove-to-catalina-displayport-not-working.284983/.
      which solving by swithing to iMac19,1, which I think WEG quite needs an enhancement
      But I tried with no luck.
       
      And I don't know is it relevant to this issue, sometimes wakeup, I got panic, somehow like this:
      Kernel Extensions in backtrace: com.apple.driver.AppleACPIPlatform(6.1)[927FAB0F-5B29-3E31-A1A4-DA7E904986C4]@0xffffff7f96b8c000->0xffffff7f96c26fff dependency: com.apple.iokit.IOACPIFamily(1.4)[9BA2613C-A129-3EDD-8DC1-2CFF6B62B832]@0xffffff7f9528f000 dependency: com.apple.iokit.IOPCIFamily(2.9)[E6E855AD-A5B2-3518-A997-1384B4360708]@0xffffff7f952a1000 dependency: com.apple.driver.AppleSMC(3.1.9)[EB9D605D-85B1-3506-8B2E-ABD195817A4F]@0xffffff7f952de000 whole panic log in attachment

      i3 8100
      Only Intel UHD630 with LG UL550 4k monitor
       
       
      Or is there any guide how to do some logging for this issue?

      I have working Mojave version of Hackintosh and it's working perfectly but when I have upgraded to Catalina it's stuck after reaching 90% of the progress bar. When I verbose the boot I got the IGPU problem and if I pass -disablegfxfirmware then I don't get any error log but the progress bar still stuck on the same position and screen became purple. Am I need anything more patch to get a working Catalina machine with Intel HD 630? If I need then how can I do it?
      My EFI link -

      For Wi-Fi:
      - 1st method: You can choose an external USB wifi dongle (I used TP-Link Archer T1U (5GHz support), TP-Link has official macOS drivers, you just need to install it
      - 2nd and I think the best method: Replace your M.2 Qualcomm Card with a compatible BCM94352Z card (you will have hand-off Bluetooth too), just install the kexts (enabled with BrcmFirmwareRepo.kext, BrcmPatchRAM2.kext, FakePCIID.kext, FakePCIID_Broadcom_WiFi.kext, they're all in my attached zip). You could buy this card from ebay, aliexpress, or amazon
       
      Issues:
      - None
      BIOS Settings:
      - BIOS version 1.15 (irrelevant)
      - Secure Boot: Disabled
      - Touchpad: Advanced
      - Boot mode: UEFI
      Getting ready for Installation:
      - Download the Catalina install zip (bootpack & postinstall): acer_aspire_V591G-55TU_cata.zip
      Installation:
      - Create an installer with any method you know (- Mac: createinstallmedia - Windows: Transmac, Vmware, Win32diskimager)
      - Copy my Clover folder to the USB's EFI folder
      - Boot with the Installer USB
      - If you stuck in boot, reboot and in the Clover bootloader select "config_debug.cfg" -> you'll have more informations about the freeze
       
      Please open the README.rtf in my install zip for more informations about the USB Installer & Post installation!
      For any system kext installation\modification you need to boot with config_debug.plist (or disable SIP manually)
      Also on Catalina the System folder is read-only, so you need to remount in rw. 
      If you have a single RAM and getting panic at boot, then you need to edit the "config.plist" with these (SMBIOS->after "Version 1.0"):
      ->Edit "Frequency" and "Size" to match your RAM values
      <key>Version</key> <string>1.0</string> <key>Memory</key> <dict> <key>Channels</key> <integer>1</integer> <key>SlotCount</key> <integer>1</integer> <key>Modules</key> <array> <dict> <key>Slot</key> <integer>0</integer> <key>Size</key> <integer>8192</integer> <key>Frequency</key> <integer>2133</integer> <key>Type</key> <string>DDR4</string> </dict> </array> </dict> </dict>  
      PowerManagement  fix:
      Set HWPEnable=YES in Clover (already set), CPUFloor to "700", Frequency to "2300" and "3200"(Normal and Turbo, if you have i7-6700HQ version then it should be "2600", "3500") and "FrequencyVectors" from "0x0d000000" to "0x07000000" in "S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Mac-A5C67F76ED83108C.plist", MSR _xcpm_idle Patch to KernelToPatch in Clover (If you have High Sierra, change "MatchOS" to 10.13):

      <key>KernelToPatch</key> <array> <dict> <key>Comment</key> <string>MSR 0xE2 _xcpm_idle instant reboot(c) Pike R. Alpha</string> <key>Disabled</key> <false/> <key>Find</key> <data> ILniAAAADzA= </data> <key>MatchOS</key> <string>10.14</string> <key>Replace</key> <data> ILniAAAAkJA= </data> </dict> </array> Reboot, and it's 800MHz in idle state, same on Windows.
       

      Elan SmartTouchpad
      I only use scrolling, one-, double- & tripletap
      If you want to try other gestures go to this link for more informations, options (v4.6.5) ->  DETAILS ABOUT THE SMART TOUCHPAD DRIVER FEATURES
      Fn Brightness keys not working with this, tried several things without success. With VoodoPS2Controller it's working, but you'll have no gestures (neither scrolling).
       
       
      Before updating to a new version of Catalina please update kexts (and clover if necessary) to newer versions to avoid kernel panics.
      Generate a serial number with Clover Configurator.app (open up your config.plist with CC then -> SMBIOS -> Serial Number -> Generate New)
       
      Catalina & Windows 10 Dual-Boot:
      Dual-boot clean install (on one drive), UEFI Only:
       
       Boot into your Mac installer, Create 2 partitions in GUID table (1 for Win (I used FAT32 but I think it doesn't matter what you choose), 1 for Mac),   Install Mac, boot with your USB, mount your EFI partition (use terminal or an EFI mounter app), create an EFI folder (if there is no folder), copy the CLOVER folder I attached to the EFI folder, restart,  Boot into your Win installer, Format the partition you created for Win, install.   Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       5.  You're done! It will booting into Clover when you start the system, and you can select Win or Mac (or another OS if installed on a 3rd partition).
       
      Dual-boot with Windows installed first (on one drive), UEFI Only:
      If you already have Windows and you don't want to lose all your data there is a hope:
      I created a video from this restore method: [Hackintosh] Dual-Boot High Sierra & Windows - when Windows already installed - no data waste - UEFI
      You need bootable Mac Installer and a full system restore image (link is in my video's description).
      (You may see errors if your EFI partition is not 200 MB)
       Boot into your Windows, resize your partition or create one for Mac.  Boot into your Mac installer and in Disk Utility format the partition you created.  Restore from image: select your full system restore image.  When it's finished restoring you just need to restart, then boot to the system with your usb.  When you successfully booted to Mac desktop, mount your EFI partition (use terminal or an EFI mounter app), open EFI, you will see there is a Microsoft folder already (don't touch that!). Copy my CLOVER folder to the EFI folder then Restart.  Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       7.  You're done! You can select your old Windows and your new macOS!
      (Only tried with Windows 8/8.1/10. I don't know Windows 7,etc.)
       
      IF YOU GETTING ERRORS DURING MAC RESTORE:
      - Make sure you have partitions in GPT
      - Windows using 100 MB EFI and will annoy the Mac restore. Don't worry, just ignore the errors.
       
      IF YOU GETTING ERRORS DURING WINDOWS INSTALLATION (could not be formatted, etc):
      - Make sure you have GPT partitions, and GPT (UEFI) installer, also disconnect all external storage drives (except the installer USB)
       
      IF YOU USED RESTORE METHOD THEN CAN'T MOUNT YOUR EFI PARTITION (No EFI partition found):
      - It's because your EFI is not 200 MB or not an "Apple" original EFI,  but do not worry, try another EFI mounter, or mount from terminal (I used EFI mounter v3: Getting errors, but you can mount and use without problem)
      - You also could "mount" the EFI from Windows:
      1st method: open cmd in administrator mode and type:
      diskpart list vol (Now select the "System" volume,(FAT 32) For example I select 4) sel vol 4 list part (Select System type partition, for example 2) sel part 2 assign letter=b (This will "mount" your EFI partition) Open Explorer++ or TotalCommander in administrator mode to manage EFI remove letter=b (This will "unmount" your EFI) 2nd method: open cmd in administrator mode and type:
      mountvol b: /s (This will mount your EFI) Open Explorer++ or TotalCommander in administrator mode to manage EFI mountvol b: /d (This will unmount your EFI) Thanks to all OSXLatitude members for helping me out! (Jake Lo, Hervé, Bronxteck, black.dragon74)!
