L'hackintosh non si risveglia dopo lo stop computer - problema sleep

4 posts in this topic

Recommended Posts

Salve ragazzi, tempo fa ho costruito il mio hackintosh e ultimamente sto riscontrato i seguenti problemi:

 

-mancata uscita dalla modalità sleep

-audio che si attiva in ritardo (ad esempio il suono dei tasti volume avviene con un ritardo iniziale)

-usb attive anche da spento

 

Ci terrei tanto a risolvere questi problemi evitando di compromettere i dati all'interno del PC.

Se vi serve qualche log chiedete pure, ma attualmente non so cosa postarvi.

 

 

MOBO GigaByte GA-z77-DS3H

CPU i7 3770 3.4 ghz (che vorrei anche overclockare)

8 Gb di ram a 1600Mhz

GPU Nvidia Gforce GTX 650 TI a 2Gb

1 TB di HD 

 

aggiornato a MacOsX 10.8.4

 

Ho configurato il tutto seguendo le guide su tonymac86 e suppongo che l'abbia fatto con chameleon.

 

Tengo a precisare che mi sono comportato da perfetto lamer e quindi di tante cose fatte non conosco nè la logica e neanche l'esistenza  :blush:

ciao scusa per l'irregolarità. Io, comunque, chiedevo dei consigli su una problematica legale (suppongo). Su tony non trovo una sezione in italiano

      There are plenty of users who suggest to use darkwake=8 or darkwake=10 or darkwake=0 boot args to solve sleep issues.
       
      Are these suggestions valid at all?
       
      For first we have to clarify something about Darkwake. The DarkWake feature was for first introduced in Mac OS X Lion. This feature allows to wake up certain parts of computer from sleep, while leaving other parts in sleep mode (for example display etc). Darkwake = display stays dark when comp wakes and performs some tasks. When tasks are done, comp should go back to sleep. But on Hack's Darkwake caused several problems, for example comps went into state, where those become inaccessible and forced reboot were needed. On some cases Darkwake caused reboots too and.. Darwake is related to Power Nap which is available since OS X Mountain Lion.

      If you really want to get some help from Hackintosh community, learn how to leave others out of guesswork! Learn how to collect diagnostics data which can help others on solving your case. It's annoying to ask over and over to provide some diagnostics related to Hack issue. That's why there are millions on unanswered posts on Hackintosh forums, their authors doesn't respect other's actually, they do not think out of their own shoes. Your first question before posting should be, what data is needed to help me, do I have provided all data available to help me immediately?
       
       
      Darkwake and XNU
       
      Darkwake is part of XNU. 
       
       
      Darkwake behaviours are defined in IOPMrootDomain.cpp.
       
      The easiest way to check XNU version is to use terminal command uname -av. 
       
      uname -av Darwin MyHack.local 19.2.0 Darwin Kernel Version 19.2.0: Sat Nov 9 03:47:04 PST 2019; root:xnu-6153.61.1~20/RELEASE_X86_64 x86_64 According to this macOS Catalina 10.15.2 uses XNU 6153.61.1.
       
      The latest publicly available source code of XNU is 4903.241.1. So we cannot check source code of latest XNU's. Please correct me if I'm wrong. 
       
      Code below reveals that boot arg darkwake correlates to enum gDarkWakeFlags.
      PE_parse_boot_argn("darkwake", &gDarkWakeFlags, sizeof(gDarkWakeFlags));  
      So lets check the xnu-4903.241.1/iokit/Kernel/IOPMrootDomain.cpp for Darkwake flags:
      // gDarkWakeFlags enum { kDarkWakeFlagHIDTickleEarly = 0x01, // hid tickle before gfx suppression kDarkWakeFlagHIDTickleLate = 0x02, // hid tickle after gfx suppression kDarkWakeFlagHIDTickleNone = 0x03, // hid tickle is not posted kDarkWakeFlagHIDTickleMask = 0x03, kDarkWakeFlagAlarmIsDark = 0x0100, kDarkWakeFlagGraphicsPowerState1 = 0x0200, kDarkWakeFlagAudioNotSuppressed = 0x0400 }; Let's translate these values into decimals and easier to read strings
      HID Tickle Early = 1 HID Tickle Late = 2 HID Tickle None = 3 HID Tickle Mask = 3 Alarm Is Dark = 256 Graphics Power State 1 = 512 Audio Not Suppressed = 1024 HID = Human-interface devices, such as keyboards, pointing devices, and digitizers like pens and touch pads.
       
      As flags are used for bitwise operations, then we can easily notice that combinations 10 and 8 are for sure invalid now. darkwake=8 equals actually to darkwake=0 and darkwake=10 equals to darkwake=2.
       
      If we check older XNU versions, then these values are removed since XNU 2782.1.97 ( = Yosemite ):
      kDarkWakeFlagIgnoreDiskIOInDark = 0x04, // ignore disk idle in DW kDarkWakeFlagIgnoreDiskIOAlways = 0x08, // always ignore disk idle kDarkWakeFlagIgnoreDiskIOMask = 0x0C According to this boot flags darkwake=8 and darkwake=10 are obsolete if you have Yosemite or newer macOS as related flags are removed from XNU. 
       
      What is the default value for darkware boot arg?
       
      According to XNU source code the default value of boot arg darkware is 3 (darkwake=3):
      static uint32_t gDarkWakeFlags = kDarkWakeFlagHIDTickleNone; We have to clarify that xnu 4903.221.2 is used since macOS Mojave 10.14.1 and xnu 4903.241.1 is used since macOS Mojave 10.14.3. How about the latest macOS? Sadly there is no source code available. 
       
      To figure out which value is defined on latest kernel we have to download the latest available Kernel Debug Kit, which is 10.15.1 build 19B77a. By using Hopper Disassembler we see that default value on macOS Catalina 10.15.1 for gDarkWakeFlags is 0x00000003, which equals to 3.
      __ZL14gDarkWakeFlags: // gDarkWakeFlags ffffff80012b93b0 dd 0x00000003 So by default Darkwake should not post any HID Tickle's. This also reveals the secret why some users encounter issues with frozen peripheral device's on Hack's when Power Nap is enabled. To use Darkwake on Hack's require very well configured USB ports.
       
       
      Power Nap & Darkwake
       
      If you have Power Nap disabled then computer shouldn't wake automatically. On most cases darkwake boot arg affects how computers should behave on case of Power Nap enabled. If everything is configured properly you do not need define darkwake boot flag at all. Anyhow, there might be motherboards, which benefit from user defined value. But keep in mind that darkwake=8 and darkwake=10 are obsolete since Yosemite.
       
       
      Which values are valid for darkwake?
       
      As flags are used for bitwise operations, then these values are valid:
       
      darkwake=0
      darkwake=1 (darkWakePostTickle behaviour)
      darkwake=2 (darkWakePostTickle behaviour)
      darkwake=3 (darkWakePostTickle behaviour)
      darkwake=256
      darkwake=257
      darkwake=258
      darkwake=259
      .. and so on...
       
      As I'm not familiar how PE_parse_boot_argn function exactly works, I cannot say much about boot arg darkwake=0. According to source code there is no any checks or behaviours defined for darkwake=0. There is a huge chance that using darkwake=0 actually equals to darkwake=3. I hope someone can clarify from source code what exactly happens if darkwake=0 is used trough PE_parse_boot_argn, but it's obvious that darkwake=0 does not equal to darkwake=NO (or darkwake=FALSE). darkwake=0 does not disable power nap, it only affects HID tickle. Please note that darkwake=3 is combination of flags 1 & 2. 1 + 2 = 3. On case we say to the system to do early (1) and later (2) HID tickle both (3), there is no any tickle at all.
       
      Some code samples from IOPMrootDomain:
      else if (!darkWakeMaintenance) { // Early/late tickle for non-maintenance wake. if (((gDarkWakeFlags & kDarkWakeFlagHIDTickleMask) == kDarkWakeFlagHIDTickleEarly) || ((gDarkWakeFlags & kDarkWakeFlagHIDTickleMask) == kDarkWakeFlagHIDTickleLate)) { darkWakePostTickle = true; } } if (darkWakePostTickle && (kSystemTransitionWake == _systemTransitionType) && (gDarkWakeFlags & kDarkWakeFlagHIDTickleMask) == kDarkWakeFlagHIDTickleLate) { darkWakePostTickle = false; reportUserInput(); } if (powerState > maxPowerState) { DLOG("> plimit %s %p (%u->%u, 0x%x)\n", service->getName(), OBFUSCATE(service), powerState, maxPowerState, changeFlags); *inOutPowerState = maxPowerState; if (darkWakePostTickle && (actions->parameter & kPMActionsFlagIsDisplayWrangler) && (changeFlags & kIOPMDomainWillChange) && ((gDarkWakeFlags & kDarkWakeFlagHIDTickleMask) == kDarkWakeFlagHIDTickleEarly)) { darkWakePostTickle = false; reportUserInput(); } } void IOPMrootDomain::reportUserInput( void ) { #if !NO_KERNEL_HID OSIterator * iter; OSDictionary * matching; if(!wrangler) { matching = serviceMatching("IODisplayWrangler"); iter = getMatchingServices(matching); if (matching) matching->release(); if(iter) { wrangler = OSDynamicCast(IOService, iter->getNextObject()); iter->release(); } } if(wrangler) wrangler->activityTickle(0,0); #endif } As you see from code examples above, there is no any huge mystery about darkwake boot arg and you should use it mostly on case when you really need to manipulate HID tickle behaviour. On most cases it's more important to properly configure you system power management rather than paying with darkwake boot arg, which can be done via terminal command pmset.
       
       
      Power Management
       
      To check Power Management settings use terminal command:
      pmset -g Also you can use Hackintool to check power management settings:
       

       
      Power Management Settings explained:
       
      displaysleep - display sleep timer; replaces ’dim’ argument in 10.4 (value in minutes, or 0 to disable) disksleep - disk spindown timer; replaces ’spindown’ argument in 10.4 (value in minutes, or 0 to disable) sleep - system sleep timer (value in minutes, or 0 to disable) womp - wake on ethernet magic packet (value = 0/1). Same as "Wake for network access" in the Energy Saver preferences. ring - wake on modem ring (value = 0/1) powernap - enable/disable Power Nap on supported machines (value = 0/1) proximitywake - On supported systems, this option controls system wake from sleep based on proximity of devices using same iCloud id. (value = 0/1) autorestart - automatic restart on power loss (value = 0/1) lidwake - wake the machine when the laptop lid (or clamshell) is opened (value = 0/1) acwake - wake the machine when power source (AC/battery) is changed (value = 0/1) lessbright - slightly turn down display brightness when switching to this power source (value = 0/1) halfdim - display sleep will use an intermediate half-brightness state between full brightness and fully off (value = 0/1) sms - use Sudden Motion Sensor to park disk heads on sudden changes in G force (value = 0/1) hibernatemode - change hibernation mode. Please use caution. (value = integer) hibernatefile - change hibernation image file location. Image may only be located on the root volume. Please use caution. (value = path) ttyskeepawake - prevent idle system sleep when any tty (e.g. remote login session) is ’active’. A tty is ’inactive’ only when its idle time exceeds the system sleep timer. (value = 0/1) networkoversleep - this setting affects how OS X networking presents shared network services during system sleep. This setting is not used by all platforms; changing its value is unsupported. destroyfvkeyonstandby - Destroy File Vault Key when going to standby mode. By default File vault keys are retained even when system goes to standby. If the keys are destroyed, user will be prompted to enter the password while coming out of standby mode.(value: 1 - Destroy, 0 - Retain)  
      If you want to disable proximitywake the this command should be used:
      sudo pmset -a proximitywake 0  
      Recommended settings for Hack's are:
      sudo pmset -a hibernatemode 0 sudo pmset -a proximitywake 0 sudo pmset -a powernap 0 Settings above disable Hibernate, Bluetooth wake by iDevices and Power Nap.
       
      To check what might prevent computer from going into sleep we can pmset tool:
      pmset -g assertions  
      So, before using blindly darkwake boot arg to solve some sleep issues, make instead sure that USB ports and Power Management settings of your Hack are configured properly.
       
       
      Sleep & Wake
       
      Quite often Hack's users have sleep/wake issues because they don't pay attention to the fact that Apple's macOS is developed for Apple hardware in mind, not regular PC's. 
       
      Of course sleep mode isn't something that Apple has invented first. Since December 1996 ACPI superseded APM. ACPI - Advanced Configuration and Power Interface. APM - Advanced Power Management. The ACPI specification defines several states for various hardware components and devices. There are global "Gx" states and sleep "Sx" states specified.
       
      Gx Name Sx Description G0 Working S0 The computer is running and the CPU executes instructions. "Awaymode" is a subset of S0, where monitor is off but background tasks are running G1 Sleeping S1 Power on Suspend (POS): Processor caches are flushed, and the CPU(s) stops executing instructions. The power to the CPU(s) and RAM is maintained. Devices that do not indicate they must remain on may be powered off S2 CPU powered off. Dirty cache is flushed to RAM S3 commonly referred to as Standby, Sleep, or Suspend to RAM (STR): RAM remains powered S4 Hibernation or Suspend to Disk: All content of the main memory is saved to non-volatile memory such as a hard drive, and the system is powered down G2 Soft Off S5 G2/S5 is almost the same as G3 Mechanical Off, except that the power supply unit (PSU) still supplies power, at a minimum, to the power button to allow return to S0. A full reboot is required. No previous content is retained. Other components may remain powered so the computer can "wake" on input from the keyboard, clock, modem, LAN, or USB device G3 Mechanical Off   The computer's power has been totally removed via a mechanical switch (as on the rear of a PSU). The power cord can be removed and the system is safe for disassembly (typically, only the real-time clock continues to run using its own small battery)  
      Since Mac OS X Lion Apple is using DarkWake, which were wrapped into Power Nap on OS X Mountain Lion. To understand and fix macOS sleep issues we also need the knowledge about sleep states which macOS comps may have. To check log of macOS computers sleep/wake we can use pmset tool. Following terminal code prints sleep/wake history.
      pmset -g log|grep -e " Sleep " -e " Wake "  
      I to check more closely sleep history then we can recognise that macOS has at least 3 different sleep "modes":
       
      Software sleep Idle sleep Maintenance sleep  
      Software sleep
      Software sleep is trigged by computer user or by some software, which is configured to put comp sleep after certain tasks done.
       
      Idle sleep
      Idle sleep is triggered by idle timer. Each time user interacts with computer idle timer is reset. If users doesn't interact within idle timer countdown time, then Idle sleep is triggered.
       
      Maintenance sleep
      If user has enabled "Wake for Ethernet network access", then macOS goes from Idle or Software sleep into Maintenance sleep immediately. 
       
      Power Nap
      If Power Nap is enabled, then computer wakes up automatically after certain period of time, handles certain tasks and goes back to sleep. Apple's documentation reveals that behaviour of power nap doesn't depend only macOS version running on comp but at hardware and it's firmware too. Documentation clearly states that comps made on different time behave differently. which points directly that Power Nap is related to the hardware/firmware too.
       
       
      According quote above we have to very carefully choose which firmware is emulated on Hack. Changing SMBIOS on Clover/Opencore can help to solve sleep issues or cause them.
       
      An example of sleep log when powernap is enabled:
      2020-01-05 09:03:23 +0200 Sleep Entering Sleep state due to 'Idle Sleep': Using AC (Charge:0%) 21 secs 2020-01-05 09:04:29 +0200 Sleep Entering Sleep state due to 'Maintenance Sleep': Using AC (Charge:0%) 1945 secs 2020-01-05 09:37:39 +0200 Sleep Entering Sleep state due to 'Maintenance Sleep': Using AC (Charge:0%) 3187 secs 2020-01-05 10:31:33 +0200 Sleep Entering Sleep state due to 'Maintenance Sleep': Using AC (Charge:0%) 12467 secs 2020-01-05 14:00:06 +0200 Sleep Entering Sleep state due to 'Maintenance Sleep': Using AC (Charge:0%) 11312 secs 2020-01-05 17:08:40 +0200 Wake DarkWake to FullWake from Normal Sleep [CDNVA] : due to UserActivity Assertion Using AC (Charge:0%)  
      An example of sleep log, when ethernet wake and power nap is disabled:
      2020-01-03 18:15:43 +0200 Sleep Entering Sleep state due to 'Idle Sleep':TCPKeepAlive=inactive Using AC (Charge:0%) 3210 secs 2020-01-03 19:09:13 +0200 Wake Wake from Normal Sleep [CDNVA] : due to XDCI CNVW/HID Activity Using AC (Charge:0%) 207 secs 2020-01-03 19:12:40 +0200 Sleep Entering Sleep state due to 'Idle Sleep':TCPKeepAlive=inactive Using AC (Charge:0%) 165903 secs 2020-01-05 17:17:43 +0200 Wake Wake from Normal Sleep [CDNVA] : due to XDCI CNVW/HID Activity Using AC (Charge:0%) As we see from log above, computer stays in sleep without any wakes and no 'Maintenance Sleep'.
       
      So there are several variables which have effect on your computer sleep/wake behaviour and the solution that helped another people, might be useless or even worse on you case.

      Description
       
      Idle Sleep issue detected on both, genuine Mac's and Hack's, where have installed latest macOS Catalina 10.15.2.
       
      Currently known about the issue:
      Issue noticed by various users after upgrading to macOS 10.15.2 Both genuine Mac's and Hack's are affected. Comps which are running on battery power are not affected as agent is disabled at battery power. macOS 10.15.2 replaces previous version of parsec-fbf agent. macOS 10.15.2 kernel uses new version of XNU 6153.61.1. macOS 10.15.1 kernel uses XNU 6153.41.3. Bot the macOS 10.15.2 and macOS 10.15.0 use the same com.apple.parsec-fbf.plist launch agent definition file. Not sure are all comps with 10.15.2 affected or only with specific system configuration Issue is not reported on any older macOS versions this far. Only Idle Sleep is affected, Software Sleep works fine. Agent can be killed via Activity Monitor, but it revives immediately again and still prevents the Idle Sleep Agent does not stop display to go into sleep, which makes hard to notice the issue on genuine Macs. Disabling parsec-fbf agent solves the issue  
      CoreParsec.framework is part of Siri
       
      pares-fbf is part of CoreParsec.framework which is installed on /System/Library/PrivateFrameworks/CoreParsec.framework.
       
      Info from /System/Library/PrivateFrameworks/CoreParsec.framework/Versions/Current/Resources/Info.plist:
      Bundle identifier: com.apple.siri.parsec.CoreParsec Privacy - Location Usage Description: Spotlight, Messages, Lookup & Safari Suggestions use your location to provide more accurate local results.  
       
      Content of com.apple.parsec-fbf.plist which defines the agent:
      <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>EnablePressuredExit</key> <true/> <key>EnableTransactions</key> <true/> <key>Label</key> <string>com.apple.parsec-fbf</string> <key>LaunchEvents</key> <dict> <key>com.apple.xpc.activity</key> <dict> <key>com.apple.parsec-fbf.flush</key> <dict> <key>AllowBattery</key> <false/> <key>Interval</key> <real>3600</real> <key>Priority</key> <string>Maintenance</string> </dict> </dict> </dict> <key>MachServices</key> <dict> <key>com.apple.parsec-fbf</key> <true/> </dict> <key>POSIXSpawnType</key> <string>Adaptive</string> <key>ProcessType</key> <string>Background</string> <key>Program</key> <string>/System/Library/PrivateFrameworks/CoreParsec.framework/parsec-fbf</string> </dict> </plist>  
      Comparison of parsec-fbf on different Catalina versions:
       
      MD5 (10.15.0/parsec-fbf) = e20c200814c4ce5fcd3ae5af7394e1d1 MD5 (10.15.1/parsec-fbf) = f3fe4e16be71798fd7d3b23be089082e MD5 (10.15.2/parsec-fbf) = a97bb8b8227c063289a6e0d43582b10f  
      parsec-fbf agent binary file's are different in each macOS Catalina version. But seems that the biggest change is made in Catalina macOS 10.15.2.
       
      Binary comparison:
       
      10.15.0/parsec-fbf = 1 742 192 bytes 10.15.1/parsec-fbf = 1 736 640 bytes 10.15.2/parsec-fbf = 1 802 832 bytes  
      Left file: 10.15.0/parsec-fbf Right file: 10.15.1/parsec-fbf 1561745 same byte(s) 58019 left orphan byte(s) 52467 right orphan byte(s) 122428 difference byte(s) Left file: 10.15.1/parsec-fbf Right file: 10.15.2/parsec-fbf 1450705 same byte(s) 129662 left orphan byte(s) 195854 right orphan byte(s) 156273 difference byte(s) Left file: ./10.15.0/parsec-fbf Right file: ./10.15.2/parsec-fbf 1443572 same byte(s) 150586 left orphan byte(s) 211226 right orphan byte(s) 148034 difference byte(s)  
      According to knowledge that issue with parsec-fbf agent is not reported before Catalina 10.15.2 and each Catalina versions has his own versions of parsec-fbc agent, then we can conclude that issue is specific to the Catalina 10.15.2 only, until reported otherwise. So no need to concern if you have macOS 10.15.1 or older. Anyway, if you upgrade to 10.15.2 and get sleep issues, you have to check your system for issue described in this post. On some cases this might look like Buletooth issue but actually it's not, because when yo disable parsec-fbf agent, sleep works immediately again.
       
      How to check?
       
      pmset -g assertions  
      If computer has Idle Sleep issue and com.apple.parsec-fbf.flush is listed in assertions, then this might be the reason of why Idle Sleep fails.
       
      An example:
      pid 321(UserEventAgent): [0x00000145000b82a0] 03:09:42 BackgroundTask named: "com.apple.parsec-fbf.flush"  
      How to check sleep log?
      pmset -g log|grep -e " Sleep " -e " Wake "  
      Reason
       
      It's unknown what exactly causes this issue. Somehow parsec-fbf agent goes into state where it prevents comp to go into Idle Sleep. Probably the latest version of parsec-fbf agent introduced in macOS 10.15.2 has some kind of bug which resets idle timer. As macOS kernel uses new version of XNU (6153.61.1), this might be somehow related to both, parsec-fbf agent and kernel.
       
      Current solution:
       
      Please note that just disabling Siri doesn't help, as parsec-fbf agent is responsible for sending Spotlight, Messages, Lookup & Safari searches data too, not only Siri searches.
      launchctl unload -w /System/Library/LaunchAgents/com.apple.parsec-fbf.plist  
      As this agent sends and flushes analytical data (Spotlight, Messages, Lookup & Safari searches) sent to Apple, no any harm happens to you, if you disable this agent, Apple just cannot spoof after you anymore. 
       
      parsec-fbf agent reads and writes files in users Cache folder: ~/Library/Caches/com.apple.parsecd. If you want flush these, you can do it manually.
       
      Flushing spoofing cache manually:
      cd ~/Library/Caches rm -R com.apple.parsecd

      嗨,大家好
      Hi, everybody
      After successfully installing the Catalina and Opencore bootloaders, I encountered a problem that some applications would crash after waking up,
      Such as Chrome and Tencent QQ, these applications will become unresponsive and only be quited by force, even the system could not power off normally.
      However, none of these problems occurred before sleep.
      In addition, all of these issues occur when SMBIOS is iMac and iGPU is enabled in the BIOS, but not when SMBIOS is iMac Pro or iGPU is disabled in the BIOS.
      I am thinking that the problem may be iGPU related and I cannot fix it.
      please help me.

      Hi,
       
      I have upgraded from Mojave to Catalina 10.15.1. It went almost flawlessly. The only issue is the computer  not waking up from sleep. Just a grey screen. Hard reset is required. Of course I have been searching the Internet but to no avail.
      The sleep-awake cycle did work on Mojave.
       
      I have noted that it is now impossible to boot in save mode. Trying to do so produces  the message: " error loading kernel (0xe)" .
      Since I use Clover  I have  tried the bootflags -f en UseCache=no (in addition to -v en -x) .  I wonder if the last one is a Clover bootflag?
       
      Here are my specs:
      Motherboard Gigabyte GA H77 D3H  rev 2.0
      MacOS Catalina Version 10.15.1 (Build 19B88)
      Kernel                         Darwin 19.0.0 x86_64
      RAM                            4.00 GB
      Model Identifier        iMac14,2
      CPU                            Intel(R) Core(TM) i3-3225 CPU @ 3.30GHz
      Intel Generation      Ivy Bridge

       
      Any help is of course much appreciated!
