Hello folks! We are late, but 2023.05 releases are worth waiting.
First, OpenCore 0.9.2 brings significant improvements on GopBurstMode thanks to @mikebeaton: guard checks which ensure that it is not arbitrarily turned on; compatibility with non-standard GOP implementations; fix for potential hang on DEBUG builds; and even support for natively supported cards. The other fixes and improvements cannot be neglected either: @CaseySJ introduces a new kext quirk DisableIoMapperMapping which resolves conflicts in AppleVTD. As well, @vit9696 ensures that single user mode is disabled when Apple Secure Boot is enabled. Following the fix of ThirdPartyDrives on macOS 13.3 and above, ExternalDiskIcons also functions correctly now, thanks to @fusion71au. The Builtin text renderer receives various updates, together with the new InitialMode. Also, LogModules now supports a new ? filter for matching non-standard log lines. Last but not least, AppleCpuPmCfgLock is enabled back on macOS 13, to patch the injected AppleIntelCPUPowerManagement kext. There are also other minor improvements. Please review the full changelog below.
Lilu 1.6.5 can now detect Recovery and Installer mode on macOS 13, too. Thus, it is essential to upgrade together with plugin kexts.
As always, we continue to appreciate contributions to AppleALC database, including ALC1220 layout-id 18 for Gigabyte Z490 Aorus Master by hgsshaanxi, and layout-id 21 for ALC298 on X270 by MKjanek32. There are bundled in AppleALC 1.8.2.
RestrictEvents 1.1.1 fixes f16c patch misreporting other hw.optional features.
Last but not least, BrcmPatchRAM 2.6.6 integrates firmware for legacy BCM20702A1, thanks to @chapuza.
Enjoy,

OpenCore 0.9.1 brings better support for legacy graphic cards together with bug fixes. To begin with, @corpnewt fixed a minor printing bug in ocvalidate which led to the failure of message printing. @mikebeaton made VS Code debugging easier by providing sample config for gdb. As well, he implemented GopBurstMode quirk for faster GOP operation on older firmware; now SysReport will also include GOP memory caching reports. Thanks to @vit9696’s discovery, we also integrated the new patch for ThirdPartyDrives quirk on macOS 13.3 and above. Last but not least, @Andrey1970AppleLife has always continuously updated builtin firmware versions.
macOS Ventura introduced a new check for Continuity Camera which is only available on Kaby Lake and above. FeatureUnlock 1.1.4 patches this restriction to make it possible everywhere thanks to @khronokernel.
Users’ consistent maintenance to AppleALC database has been integrated into AppleALC 1.8.1 as well. We would like to thank @lgh07711, @DalianSky, @Pinokyo-H, @wern-apfel, and @imoize, for their contibutions to the configurations of ALC293, Alder Lake PCH-P High Definition Audio Controller (0x51C8), ALC269, ALC623, ALC295, and ALC255 respectively.
To investigate NSS issues, @lvs1974 updated AirportBrcmFixup to 2.1.7 to dump debugging logs from the methods AirPort_BrcmNIC::setTX_NSS, AirPort_BrcmNIC::getTX_NSS, and AirPort_BrcmNIC::getNSS.
As of RestrictEvents 1.1.0, it is possible to disable hw.optional.f16c on macOS 13.3 and above. This is particularly useful on Ivy Bridge CPUs where AVX 2.0 instructions are not present, resulting in CoreGraphics.framework crash.
We appreciate @AsdMonio who fixed board-id length calculation for legacy Mac models where it is shorter. This is now integrated into BrcmPatchRAM 2.6.5.
In BrightnessKeys 1.0.3, @ChefKissInc added support for certain laptops including AMD ones where kIOACPILegacyPanel is used.
Thanks to @1Revenger1, one of the primary authors of our VoodooPS2 project, version 2.3.5 removed actAsTrackpad and related logic; and on Elan Touchpads, Trackpoint logic is now powered by VoodooInput.
Enjoy,

revpatch’s f16c argumentHello. Sorry guys! I have been sick and busy moving, hence I skipped the February 2023 message.
While there is not much listed in the changelog, OpenCore 0.9.0 has improvements on graphics thanks to @mikebeaton, including verbose boot log appearance, versioning information for the EnableGop UI tool, and AMD support and GOP offset auto-detection, with which macOS 10.11+ gets support for the EnableGop vBIOS insertion script. As well, the quirk ProvideCurrentCpuInfo now supports macOS 13.3 DP. Lastly, we included precompiled EDK-II EfiRom and GenFfs in Utilities/BaseTools with OpenCore releases.
For many years, AppleALC 1.8.0 enlarges its codec and layout database again with new and improved support for ALC274 (layout-id 28), ALC256 (layout-id 95), and ALC236 (layout-id 55) thanks to contributions from @Tweakkinn, @Floron, and @8DireZ3.
As a minor improvement, MaciASL 1.6.4 deletes broken URLs patches.
In the wake of stability, VirtualSMC 1.3.1 includes a tiny fix for smcread -l output.
VoodooPS2 2.3.4 introduces two fixes: device count detection when ps2rst=0 is set, and handleClose not being called by VoodooInput, thanks to @1Revenger1.
Last but not least, Lilu 1.6.4 adds AMD IGPU detection.
Enjoy,

OpenCore 0.8.8 includes several practical fixes: Synchronising with upstream, @savvamitrofanov updated the EDK II package to edk2-stable202211. As well, @Andrey1970AppleLife provided us with the latest firmware and keyboard layout information. On Apple Silicon, the prebuilt mtoc binary is now universal, together with fixed OpenDuet build and new secure PE/COFF loader. The ocvalidate tool now allows duplicate tool if FullNvramAccess is different, authored by @mikebeaton. As for the kernel patching engine, @Goldfish64 fixed blocking entries not being processed if one was skipped due to Arch. In addition, he also fixed intermittent prelinking failures caused by XML corruption when kext blocking is enabled. @vit9696 also changed the logic of picker hiding: now the magic Acidanthera sequence from OpenCore files is removed, and .contentVisibility file is added to hide and disable boot entries. For better Duet debugging, QemuBuild.command supports Linux thanks to @MikhailKrichanov’s effort. Last but not least, @Goldfish64 added SD card device path support for boot device selection.
Having hibernated for nearly two years, VoodooInput 1.1.3 is revived with trackpoint logic improvements by @1Revenger1, seperated X and Y axis, higher solution. The addition of divisor for scroll and mouse movement also makes the Voodoo projects better ones. One more thing, @kprinssu worked around crashes with USB devices on macOS 13.
In FeatureUnlock 1.1.2, @khronokernel added AirPlay to Mac unlocking inside Control Center.app.
With continuous contributions to our AppleALC database, new layout configurations for ALC255, ALC1220, ALCS1220A, and 700 series PCH HD Audio have been added thanks to @juniorcaesar, @CaseySJ, and @dreamwhite; these are added to AppleALC 1.7.8.
Included in WhateverGreen 1.6.3, @nikey22 added various GPU identifiers from different Macs, together with the new property disable-telemetry-load which disables iGPU telemetry loading by @Goldfish64.
VoodooPS2 2.3.3 fixed scrolling and button issues, as well as DynamicEWMode problem on Lenovo ThinkPad Laptops, thanks to @1Revenger1.
@al3xtjames added Raptor Lake CPU model as of Lilu 1.6.3.

To begin with, OpenCore 0.8.7 introduced several minor changes primarily in the GUI. With some reverse engineering from @mikebeaton, and additional helpful input from @cdf and @tsialex, we have now added support for Apple builtin picker on models GPUs without Mac-EFI support, and now the selected entry can be successfully launched using BootKicker.efi or PickerMode Apple. As well, @dakanji updated spoof proof UEFI 2.x checking to OpenVariableRuntimeDxe. After some discussion, we introduced Misc -> Boot -> HibernateSkipsPicker not to show picker if waking from macOS hibernation, as a boolean value, in lieu of string settings. @Shaneee fixed TSC/FSB for AMD CPUs in ProvideCurrentCpuInfo; and @mikebeaton removed unwanted clear screen when launching non-text boot entry. We would also like to thank @dreamwhite who helped created the com.apple.recovery.boot folder hiearchy in our macrecovery script.
@Goldfish64 created daemons for each userspace function replacing hvutil and added Guest Services integration service support, together with the fix of high storage latency when heaving network I/O is occurring. These changes are included in MacHyperVSupport 0.9.3.
In FeatureUnlock 1.1.1, @khronokernel resolved patch regression on Macmini8,1 and iPad models.
Thanks to @nikey22’s contribution, W7170M/S7100X ID is now included in WhateverGreen 1.6.2. In addition, @Andrey1970AppleLife, @dreamwhite, @perez987, and @unChiled helped produce a more readable version of README documentation.
After months of silence, @lvs1974 made HibernationFixup 1.4.7 respect parameters standbydelaylow, standbydelayhigh, highstandbythreshold set via pmset utility, and introduced a new bit in hbfx-ahbm boot-arg: DoNotOverrideWakeUpTime = 64, to let macOS decide when wake for standby sleep maintenance.
Starting with VoodooPS2 2.3.2, a new boot argument ps2kbdonly=1 is introduced by @Kethen to prevent touchpad line from being disabled on reboot.
For AppleALC 1.7.7, we appreciate @littlesum contributing a new layout-id 68 for ALC256 for nuc9.

Overall speaking, OpenCore 0.8.6 brings several groundbreaking changes. To begin with, @mikebeaton updated the LogoutHook script for the compatibility with earlier versions of macOS and brought the capability of automatic installation as launch daemon/logout hook on Yosemite and above. As well, @mikebeaton fixed a recursive loop crash and early logging failure, and resolved wake-from-sleep failure on EFI 1.1 systems. After months of hard work, @mhaeuser has brought the most impressive feature in this release, dwell-clicking, to our bootloader. As always, @Andrey1970AppleLife ensures that firmware/SMBIOS info is up-to-date.
After nearly one year of hibernation, MaciASL got a minor improvement where line number breaking during scroll has been fixed, thanks to @SkyrilHD.
For AppleALC 1.7.6, we would like to thank @anderson-suga, @andreszerocross, @mishurov, and @RockJesus for their contributions to our audio configuration database.
In CryptexFixup 1.0.1, @khronokernel added support for in-OS macOS installation via Install macOS.app on Big Sur and newer. As well, he refactored model patch set detection, and replaced the previously unused boot argument -disable_uni_control with -disable_sidecar_mac in FeatureUnlock 1.1.0. Last but not least, in RestrictEvents 1.0.9, the new revblock userspace processes blocking is added, together with displaypolicyd blocking for genuine MacBookPro9,1/10,1, mediaanalysisd for Metal 1 GPUs on Ventura, and conditional blocking for PCIe/memory notifications on MacPro7,1 SMBIOS.

As usual, there are no critical updates to OpenCore 0.8.5, as recent beta versions of macOS 13 tend to be stable. To begin with, @Andrey1970AppleLife updated builtin firmware versions which might be useful for the official macOS update. Then, several more updates regarding Hyper-V, including the correction for CPU objects that are exclusively available in Windows Server 2022, and extra hot-adding/removing device path expansion support, have been carried out by @Goldfish64. As well, we improved verbose logging for kernel patching, which can be useful for developers to filter patcher status. That’s it.
@Goldfish64 pushed a bunch of updates to MacHyperVSupport 0.9.2: The issue with control key pressing has been fixed, together with DMA allocation problems and another one with buffer overrun in network packet sending; VMBus implemenations get improved; intermittent hangs storage and network drivers are addressed. Finally, he added support for storage disk hot-adding/removing and that for guest restart via Restart-VM; time synchronization support for the guest machine has landed as well.
Thanks to the hard work of @dhinakg and @khronokernel, those CPU models without AVX2.0 support can boot normally by installing the Apple Silicon Cryptex (OS.dmg) with the help of the new Lilu plugin - CryptexFixup. Still, this breaks delta updates (ref), and we are looking forward to patches and contributions to this.
For VoodooPS2, we would like to give credits to @diepeterpan who fixed disabled keyboard after reboot. Users with the common problems can now enjoy VoodooPS2 2.3.1. Also, @lalithkota improved compatibility with BCM43142A0 on macOS Big Sur in BrcmPatchRAM 2.6.4.
Enjoy,

With the heatwave moving away in Europe, we are finally approaching the fall. And it’s also about time to embrace the new OS updates coming this month and/or in October.
Compared to OpenCore 0.8.3, the changes introduced in 0.8.4 are fairly minor. Following @mikebeaton’s groundbreaking work on NVRAM, our mission is finalised by syncing the checks for LoadEarly in ocvalidate and the addition of the new option FullNvramAccess allowing direct access to NVRAM. When it comes to Hyper-V support, @Goldfish64 brought the new SSDT-HV-DEV.dsl for better compatibility with older macOS versions on Windows 10 and newer; in addition, he fixed a SysReport crash on Pentium 4 systems, and another crash on anExitBootServices call while using DEBUG builds and file logging. For developers, @mhaeuser made a new ProcessKernel utility for testing kext injection by reading users’ config, making tests easier; in addition, @mikebeaton fixed 32-bit userspace build support on macOS. With basic set of NetworkPkg drivers with HTTP boot support included in OpenCore, we can start working on a new EFI tool which downloads and boots macOS Recovery, replacing macrecovery. Last but not least, we updated the zlib library to 1.2.12, and @savvamitrofanov made characters invisible on password input in ocpasswordgen. We would also like to thank @dreamwhite for his constant and solid work to defeat all warnings in our Python scripts.
@Goldfish64 brought a bunch of changes to MacHyperVSupport, providing a more seamless experience for Hyper-V users. These include PCI passthrough support, a fix for IOPCIBridge crash on macOS 12 and newer, and a new hvshutdown daemon for Hyper-V shutdown requests. As well, macOS 10.4 and 10.5 support has been added, together with the standardisation of boot arguments.
For VoodooPS2, in spite of small changes, we fixed variable shadowing to make the code more consistent.
We would also like to thank @hgsshaanxi and @Feartech for their contributions to our AppleALC codec database for ALC222, ALC235, and ALC255 (3234). Also, without @vandroiy2013’s consistent maintainance, the AppleALC project would not even have been alive.
Thanks to the developers of dmidecode, our fork has been updated to upstream a1a2258f with Apple Silicon support by @vit9696.
It is a pity that no further progress has been made for Skylake users spoofing as Kaby Lake. We are looking forward to contributions reviving the support for Skylake.
Enjoy our updates and macOS Ventura,

Hi everyone! Nothing much for this month. We’re slowly progressing on merging in PRs and pushing some updates to the guides before I start working on reorganizing the install guide as mentioned in the previous post.

Driver -> LoadEarly in ocvalidateFullNvramAccess option for tools which require direct access to NVRAMSSDT-HV-CPU.dsl with SSDT-HV-DEV.dsl for compatiblity with older macOS versions on Windows 10 and newerSysReport on Pentium 4 systemsHowdy! We wish you enjoyed this summer as life is getting back to normal. It has been a while since the last message from @vit9696 in February 2022, but the monthly greeting is back now.
In addition to the fix for one of the most important OpenCore quirks, AvoidRuntimeDefrag, in our July 2022 release, the new updates to OpenCore (again by @mhaeuser) make it possible to load the Kernel Collection on macOS Ventura beta 3 and above. Thanks to @savvamitrofanov’s hard work, we have integrated the ext4 file system driver into OpenCore. In addition, @Goldfish64 fixed OSBundleLibraries_x86_64 handling and a crash when using kext blocking for cacheless injection, and another issue with FAT binary architecture selection. Furthermore, he added macOS 10.4 and 10.5 support to the AllowRelocationBlock Booter quirk, and CPU cache info injection for macOS 10.4 to the ProvideCurrentCpuInfo quirk. @mikebeaton brought another significant code refactoring for NVRAM operations by introducing OpenVariableRuntimeDxe, so now it is possible to specify drivers which need to be loaded before NVRAM initialisation. What’s more, he made various improvements to AudioDxe, including the new --force-device and --codec-setup-delay options, the removal of default codec connection delay, as well as the change of unit (from microseconds to milliseconds) in Audio -> SetupDelay. Brought by the same author, @mikebeaton contributed a new option named --show-csr to the ToggleSipEntry tool for toggling SIP boot menu, and fixed a rare assertion caused by label animation initialisation in OpenCanopy. Last but not least, RsaTool is no longer dependant on macOS system SSL thanks to @dhinakg.
When it comes to Lilu, @mhaeuser addressed the kernel panic on macOS Ventura beta 3 and above by fixing the segment name for the new Kernel Collection. Although a small change, without his contribution, all Lilu plugins would have stopped working. As well, @Goldfish64 disabled EFI64 runtime APIs when -legacy is used on 32-bit kernels.
Although there are not many updates to our AppleALC v1.7.4 release, @wern-apfel corrected the pinconfig data for ALC294 with layout-id 15, and @Ardhi9696 contributed new audio data with layout-id 25 for ALC1220 on MSI GE73 Raider RGB 8RF.
While Apple removed support for Skylake in macOS 13, it is easy to spoof it as Kaby Lake. Building off the preliminary support in WhateverGreen v1.6.0, v1.6.1 addressed HEVC playback problems thanks to @abenraj and @dhinakg. However, further investigation is required for a proper solution to the intermittent flickering, which we wish to include in the next release.
Enjoy the last spot of summer,

Hello everyone! It’s been a while since I’ve posted one of these, and it’s about time that I posted.
I’m happy to share that our build repo is now running on an M1 machine, drastically improving build times - 30-minute builds of OC are now 7 minutes! More plugins have also been added, and development on the build repo will continue in the future.
Let’s jump to the crux of the matter though - the guides.
Many of you have probably been wondering why the install guide has remained on 0.7.8 for a while when we’re up to 0.8.3 already. Albeit the changes between 0.7.8 and the latest version haven’t been major, it has been a while since the guides have been getting updates. How come?
Well, the dortania team has not had as much time or as many active people as it once had. Mykola (khronokernel) has moved on to legacy Macs. And I no longer have the abundance of time I had while under a lockdown order.
Avery (@1Revenger1) and I, however, have been actively working to change this. First off, PMheart is helping out with maintaining the guides, recently reviewing a PR to the power management section of the post-install guide. In addition, we’ve finally been able to find some time to go through PRs and issues, and thanks to the help of several external contributors - @hkusdaryanto, @dreamwhite, @YuiiiPTChan, @Krazy-Killa, @thegermanguyben, and @extremegrief1 - we’ve been able to update the install guide to 0.8.3. The post-install guide does need updates for 0.8.3 too, but these are minor updates that will be completed in the near future. There are still many issues and updates that all of the guides need though.
This does raise the question - haven’t the updates to OC been minor? Why has it been so hard to keep the install guide up to date?
Well, the answer lies in how the install guide is organized. Currently, it’s organized by CPU generation, and all aspects of configuring your config.plist for that generation are covered in one page. However, this design leads to a humongous amount of copy and paste - there are 26 config pages as of current, and a lot of the core content is shared among the pages, but with different variations. This makes it incredibly difficult to change all the pages and ensure nothing is missed, and it also makes any PRs fairly difficult to review.
To combat this, we’ve come up with a new idea of organizing the guide: instead of by generation, by config.plist section. Each section of the config (ie. ACPI, Booter, DeviceProperties, Kernel) would be its own page, and shared configuration for several generations would be grouped on each page. This would significantly reduce the amount of repeated content and allow updates to the guide to be made much more easily. To better demonstrate, here’s a demo site.
Alongside this, we’d also like to combine the current WiFi Buyers Guide, GPU Buyers Guide, and Anti-Hackintosh Buyers Guide into one guide to have compatibility info in one central place. This new guide would be called the Hackintosh Compatibility Guide.
We know that the best way to get feedback is to ask the users, so we’re asking for public comment on these proposed changes. Please comment down in the comments below.
Thank you all,
