Acidanthera Updates: A message from PMheart

Embracing a warm spring, we published our 2023.04 releases.

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.
