775i945GZ Sleep Works But Odd Behavior, Long Wake

6 posts in this topic

Recommended Posts

Setup:

 

• Retail Mountain Lion 10.8.2

• ASRock 775i945GZ

• Intel Core 2 Duo E4700

• Sapphire AMD HD 5750 1Gb

• 4 GB Ram

 

DSDT:

 

• Patched TMR, PIC, RTC, HPET, PWRB, _WAK, USB

• Renamed TMR, PIC, COPR, USB0, USB1, USB2, USB3, EUSB to TIMR, IPIC, MATH, UHC1, UHC2, UHC3, UHC4, EHC1

• Added SBUS device

 

Working:

 

• Audio - ALC888 with DSDT patch & patched AppleHDA.kext

• Video - Full QE/CI/Resolution by adding device id to ATI5000Controller.kext & AMDRadeonAccelerator.kext and DSDT patch (for 10.8.2 had to roll back to 10.8.0 ATI5000Controller.kext)

• Ethernet - Added AppleRTL8139Ethernet.kext to IONetworkingFamily.kext/Contents/Plugins/ and DSDT patch for built-in

 

Kinda Working:

 

• Sleep - Sleep works, but the fans remain running for about 30 seconds and then turn off (system is asleep). When system wakes (by keyboard key or mouse click) it takes about 5 to 10 minutes for the monitor to wake up and for the USB devices to get power (USB device used to wake has power, others don't). Sometimes sleeping the system a second time does not work and results in black screen with fans still running. Additionally, I have to patch AppleRTC.kext to prevent a CMOS reset when waking from sleep.

 

I have attached my DSDT.

Totally off-topic but how did you manage to install 10.8? Did you make a dvd or did you boot from usb? I have a similar system her from a friend of mine but it wont boot from usb. Hope you dont mind i took your dsdt to try this machine? What is your bios version?

Booting from a USB drive didn't work for me either. I used a laptop SATA drive to create an installer and mounted it internally on the SATA bus. That booted just fine.

      The display sleep does not work correctly. Starting with Mac 10.12.4, the display sometimes does not wake up. The backlight works, there is no image, a black screen. Currently installed 10.14.1. All the same. If the display is sent to sleep, then sometimes it can wake up in a black screen with a working backlight. From the description, it is not difficult to guess that the display sometimes wakes up correctly and sometimes wakes up in a black screen. In the course of the experiments, I also saw that the display sometimes woke up and showed the boot screen (the Apple logo and progress bar), a second after that the desktop appeared. This behavior occurs only when the display wakes up on a black screen and then I close and open the laptop cover again, after which the boot screen sometimes appears for a second, but sometimes nothing appears, the system just hangs.
      I hope I clearly described the symptoms of the problem.
       
       
      The screenshot was taken after the experiment. I sent the display to sleep, then woke it up. He woke up in a black image with burning lights. Then I closed and opened the laptop bucket, pressed the space bar and waited a few seconds. After a few seconds, the boot screen with the Apple logo appeared and then the desktop appeared. Immediately made a screenshot.

      Hi, my hackintosh won't sleep!
      It often sleeps for 3-5 seconds and auto wakes up.
      sometimes it can't enter the sleep mode even you click the sleep button.
      I have uploaded my DSDT file.
      but I don't know how to patch DSDT.
      If you know how to solve this issue, please help me!
       
      Cheers,
      Brian

      1, my hackintosh machine can sleep but just for a few seconds and the fans and HDD or some devices will start working.
      2, i have tried many ways to solve this issue, such as install DSDT.aml and Patch USB limit.
      Do you have any method to solve this issue?
      I really want some useful advice from you!
      Thanks for replying.

      Hello. My hardware is:
      AMD Athlon X2 7750 dual-core
      Gigabyte NVIDIA 8400GS 512MB ( [VGA] ,HDMI,DVI)
      Motherboard Gigabyte based on NFORCE without AHCI support (only IDE)
      I have successfully installed Mac OS Yosemite, Mavericks and El Capitan with AppleNFORCEATA.kext
      But I can't use it with Mac OS 10.8, don't know why, it just gives error and my internal HDD's are not appearing in Disk Utility.
