If you are using target codec 0x11d4198b, you may need to also zero out codec compare 0x11d4198a (a new supported codec in 10.12).
Mac os high sierra compatibility issues Patch#
Some audio codecs will require an additional patch (AppleHDA) As long as you don't re-assign them in SysPrefs->Keyboard->Shortcuts, this is a fine work around. The new VoodooPS2Controller.kext v1.8.25 or later maps the brightness keys to F14/F15.
Note: In some cases, this is issue from 10.12 is already fixed in 10.13. The solution appears to be removing unused connectors from the ig-platform data in the framebuffer kext: But now the problem appears also with MacBookAir6,2 and MacBookPro11,1. May be related to SMBIOS changes, as similar effects were observed when using MacBookPro11,2 with previous versions of OS X/macOS. The same effect is observed after wake from sleep. This usually clears up after about 20 seconds. Shortly after login (and somewhat prior to login), the mouse and/or graphics may seem unresponsive. Haswell (and Broadwell) lags/pauses/unresponsiveness shortly after boot (and after wake from sleep)

Install IntelGraphicsFixup.kext + Lilu.kext. HD4400/HD4600 crashing with Safari and video playback It seems to be a WIP and has some issues, however. Karabiner Elements appear to be a replacement.
Hopefully it is fixed soon with an update. With recent versions of Clover (r4155+), you can also set ist/KernelAndKextPatches/KernelIvyXCPM=true. This flag was typically used with certain Ivy Bridge CPUs due to problems with ssdtPRgen.sh and native power management. xcpm is no longer available for Ivy Bridge CPUs Use VoodooPS2Controller.kext v.18.25 or later. Never mind though, you can enable it in Terminal: But if you did a fresh install, this option is no longer present. If you had "Anywhere" already selected, upon updating to 10.13, it will still be available. Run Apps from Anywhere is now missing from SysPrefs -> Security & Privacy -> General Use VoodooPS2Controller.kext v1.8.28 or later. VoodooPS2Controller.kext versions prior to 1.8.24 will cause a KP Requires display override with patched EDID. These kexts have been not working since 10.12.4.īlack screen (or glitchy screen) on wake with Kaby Lake and Skylake graphics IntelBacklight.kext and ACPIBacklight.kext not working For example, to set to 16000ms (16 sec), use kernel flag: abm_firstpolldelay=16000 With ACPIBatteryManager.kext 1.81.4 or later, you can also increase the FirstPollDelay (default 4000ms) by using RMCF (see SSDT-ACPIBATT.dsl in the ACPIBatteryManager github) or by using kernel flag abm_firstpolldelay. Same goes for NVMe (TRIM cannot be disabled).Īlso, HDD may be too slow and can cause startup problems related to battery status. TRIM and APFS can cause slow boot which contributes to a timing related problem with system battery status. Use ACPIBatteryManager.kext 1.81.3 or later:Īlso, if you installed on APFS, disable the trim patch. You can hide it with ist settings.īattery status not showing (even with correctly patched ACPI) Read here: Įxtra/new Preboot entry showing in Clover with APFS setup You can also inject the properties with ACPI. The new plists linked from my guide already have these injections (for Nvidia only I will add AMD later).

Instead you need to inject properties that prevent the VESA drivers from loading for the discrete graphics device and use the IGPU only. There is an issue with the VESA drivers and the dual-GPU scenario. Problems booting the installer with dual-GPU (eg. no TRIM support for your SSD in that case) disable the any TRIM patch you may be using (eg. Incompatibility will result in slow boot and other problems (battery status not showing, trackpad prefpane not showing, etc). The new APFS file system is much more sensitive to SSD hardware/firmware compatibility with regards to TRIM than HFS+J. Then you'll have an opportunity to install the latest Lilu (and other Lilu based plugins) in order to fix the problem.
Mac os high sierra compatibility issues update#
If you neglect to update prior to the update (and now have KP), use an invalid ig-platform-id (to disable the graphics drivers) and specify kernel flag -liluoff such that Lilu.kext and the graphics kexts do not load. Prebuilt Lilu.kext is available from here: Lilu 1.2.0 is too old for 10.13.2 and will panic. Only if you have a question regarding the content of this post, or have a an idea for an additional Q/A in this thread, reply here. Please do not ask questions regarding your specific problem in this thread. The problems listed here are likely to be experienced by anyone installing macOS High Sierra 10.13.
