HibernationFixup Changelog

v1.5.2

  • Adapt code to make it work correclty in macOS Sequoia.

v1.5.1

  • Added constants for macOS 15 support

v1.5.0

  • Auto hibernation: make sure auto-hibernate feature only happens when hibernatemode is set to 3. (Never with mode 0 or 25).
  • Fix minor typos in code and debug log. Plus better formatting.

v1.4.9

  • Add macOS 14 (Sonoma) constants

v1.4.8

  • Take into account a full wake event only if the local user provoked this event (stabilize switching to hibernate mode)

v1.4.7

  • Respect parameters standbydelaylow, standbydelayhigh, highstandbythreshold set via pmset utility
  • Introduce a new bit in hbfx-ahbm boot-arg: DoNotOverrideWakeUpTime = 64, to let macOS decide when wake for standby sleep maintenance

v1.4.6

  • Added constants for macOS 13 support
  • Decouple WhenBatteryIsNotCharging/WhenBatteryIsAtWarnLevel and minimal capacity in parameter hbfx-ahbm

v1.4.5

  • When battery level is critical, try to put macOS into sleep/hibernate mode only once per minute.

v1.4.4

  • Automatically puts macOS into sleep/hibernate mode when WhenBatteryIsAtWarnLevel or WhenBatteryAtCriticalLevel bit is set in hbfx-ahbm. If battery kext does not provide these levels, additional bits for remaining capacity can be specified (RemainCapacityBit1, RemainCapacityBit2, RemainCapacityBit3, RemainCapacityBit4).

v1.4.3

  • Use method routeMultipleLong instead of routeMultiple in order to avoid conflict with DebugEnhancer

v1.4.2

  • Use method routeMultipleLong instead of routeMultiple in order to avoid conflict with future versions of CpuTscSync

v1.4.1

  • Added constants for macOS 12 support.

v1.4.0

  • Auto hibernation: added possibility to disable power event kStimulusDarkWakeActivityTickle in kernel, so this event cannot be a trigger for switching from dark wake to full wake. Can be turned on via bit DisableStimulusDarkWakeActivityTickle=128 in boot-arg hbfx-ahbm.
  • Support options in NVRAM (GUID = E09B9297-7928-4440-9AAB-D1F8536FBF0A or LiluReadOnlyGuid)

v1.3.9

  • Auto hibernation: properly handle transition from dark wake to full wake
  • Extend method emuVariableIsDetected in order to use EfiRuntimeServices if nvram cannot be accessed in standard way

v1.3.8

  • Improve auto hibernation: immediate hibernate if standbydelaylow / autopoweroffdelay is 0, fast resume after hibernate, code cleanup

v1.3.7

  • Refactoring, setup next RTC wake manually if IOPMrootDomain::setMaintenanceWakeCalendar was not called before sleep
  • Force next sleep if maintanence wake type is detected (RTC/SleepService/Maintenance)

v1.3.6

  • Added MacKernelSDK with Xcode 12 compatibility

v1.3.5

  • Postpone RTC wake in AppleRTC::setupDateTimeAlarm according to current standby/autopoweroff delay (if auto-hibernate feature and standby/autopoweroff is on) in order to avoid earlier wake.

v1.3.4

  • Improve auto-hibernate feature: correct next wake time disregarding the current sleep phase.
  • Added constants for 11.0 support.

v1.3.3

  • Improve auto-hibernate feature: support standby and autopoweroff separately (with respective delay). Immediate hibernate is possible with zero delay.

v1.3.2

  • Fix nvram.plist saving in Catalina, new path is used when the root folder is not writable: /System/Volumes/Data/nvram.plist

v1.3.1

  • Code refactoring, fix duplicates in log, auto-hibernate can work without power source

v1.3.0

  • Do not use recursive iterator to detect EmuVariableUefiPresent (based on panic report analysis)

v1.2.9

  • Improve auto-hibernate feature: if power nap is enabled, hibernation will start after next Maintenance/SleepService wake (standbyDelay value is respected)

v1.2.8

  • Fixed memory leaks
  • Fixed EmuVariableUefiPresent detection (nvram.plist will be properly saved if EmuVariableUefiPresent == Yes in ioreg)
  • Improve auto-hibernate feature: modify next wake time only before regular sleep

v1.2.7

  • Unified release archive names

v1.2.6

  • Allow loading on 10.15 without -lilubetaall
  • Fix minor typos in code and comments (credits to PMheart)

v1.2.5

  • Improve auto-hibernate feature: modify next wake time to currentTime + standbyDelay

v1.2.4

  • New feature: forces hibernate mode depending on specified factors (auto hibernate modes)

v1.2.3

  • Basic 10.14 support

v1.2.2

  • Fix a name conflict for config variable
  • Improve pci patch (allow to write to PCI config command register, but bit memory space must be always set )

v1.2.1

  • Save hibernation keys in NVRAM only if boot-arg -hbfx-dump-nvram is specified or if the second bank of RTC memory (next block of 128 bytes) is not available
  • PCI Family patch is always enabled, boot-arg -hbfx-patch-pci is obsolete. A new boot arg -hbfx-disable-patch-pci is introduced to disable any patching

v1.1.7

  • Fixes for 1.1.6b (Release was non-working)
  • Use pollers to provoke writing of SMC-keys earlier

v1.1.6

  • Requires Lilu 1.1.6
  • Compatibility with High Sierra
  • PCI Family patch was improved
  • New boot-arg hbfx-patch-pci=[comma-separated list of ignored devices] supported

v1.1.5

  • Added OSBundleCompatibleVersion

v1.1.4

  • Fix system freeze and black screen when resume after hibernation (Sierra only)

v1.1.3

  • Panic handling and writing to nvram.plist

v1.1.2

  • Works with EmuVariable

v1.1.1

  • Call file sync method (to be sure that nvram.plist will be written)

v1.1.0

  • Write NVRAM to file

v1.0.0

  • Initial release
