# Userspace Issues

Issues regarding once you've booted the installer and the GUI has loaded.

# macOS installer in Russian

Default sample config is in Russian because slavs rule the Hackintosh world, check your prev-lang:kbd value under NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82. Set to 656e2d55533a30 for American: en-US:0 and a full list can be found in AppleKeyboardLayouts.txt. For those using with a simple text editor(ie. UEFI Shell, Notepad++, etc), 656e2d55533a30 will become ZW4tVVM6MA==

You may also need to reset NVRAM in the boot picker as well

Still didn't work? Well time for the big guns. We'll force remove that exact property and let OpenCore rebuild it:

NVRAM -> Block -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> Item 0 then set it Type String and Value prev-lang:kbd

# macOS Installer being damaged

If you've download macOS before October 2019, you likely have an expired macOS Installer certificate, there's 2 ways to fix this:

  • Download newest copy of macOS
  • Change date in terminal to when the certificate was valid

For the latter:

  • Disconnect all networking devices(Ethernet, disable Wifi)
  • In the recovery terminal set to September 1st, 2019:
date 0901000019

# Stuck on or near IOConsoleUsers: gIOScreenLock.../gIOLockState (3...

This is right before the GPU is properly initialized, verify the following:

  • GPU is UEFI capable(GTX 7XX/2013+)
  • CSM is off in the BIOS
  • Forcing PCIe 3.0 link speed
  • Double check that ig-platform-id and device-id are valid if running an iGPU.
    • Desktop UHD 630's may need to use 00009B3E instead
  • Trying various WhateverGreen Fixes
    • -igfxmlr boot argument. This can also manifest as a "Divide by Zero" error.
  • Coffee Lake iGPU users may also need igfxonln=1 in 10.15.4 and newer

# Scrambled Screen on laptops

Enable CSM in your UEFI settings. This may appear as "Boot legacy ROMs" or other legacy setting.

# Black screen after IOConsoleUsers: gIOScreenLock... on Navi

  • Add agdpmod=pikera to boot args
  • Switch between different display outputs
  • Try running MacPro7,1 SMBIOS with the boot-arg agdpmod=ignore

For MSI Navi users, you'll need to apply the patch mentioned here: Installer not working with 5700XT #901

Specifically, add the following entry under Kernel -> Patch:

Base:

# Frozen in the macOS installer after 30 seconds

This is likely due to faulty or outright missing NullCPUPowerManagement, the one hosted on AMD OSX's Vanilla Guide is corrupted. Go yell at Shannee to fix it. To fix the issue, remove NullCPUPowerManagement from Kernel -> Add and EFI/OC/Kexts then enable DummyPowerManagement under Kernel -> Emulate

# 15h/16h CPU reboot after Data & Privacy screen

Follow directions here after UPDATE 2: Fix Data and Privacy reboot

# macOS frozen right before login

This is a common example of screwed up TSC, for most system add CpuTscSync

For Skylake-X, many firmwares including Asus and EVGA won't write to all cores. So we'll need to reset the TSC on cold boot and wake with TSCAdjustReset. Compiled version can be found here: TSCAdjustReset.kext. Note that you must open up the kext(ShowPackageContents in finder, Contents -> Info.plist) and change the Info.plist -> IOKitPersonalities -> IOPropertyMatch -> IOCPUNumber to the number of CPU threads you have starting from 0(i9 7980xe 18 core would be 35 as it has 36 threads total)

The most common way to see the TSC issue:

Case 1 Case 2

# MediaKit reports not enough space

This error is due to a small EFI, by default Windows will create a 100MB EFI whereas macOS will expect 200MB. To get around this you have 2 way to go:

  • Expand the EFI of the drive to 200MB(See Google on how)
  • Format the entire drive instead of just the partition
    • Note by default Disk Utility only shows partitions, press Cmd/Win+2 to show all devices(Alternatively you can press the view button)
Default Show All Devices(Cmd+2)

# DiskUtility failing to erase

This is either 1(or more) of 5 issues:

  • Formatting partition and not the drive, see MediaKit reports not enough space
  • DiskUtility has an odd bug where it will fail on first erase, try erasing again
  • SATA Hot-plug support in the BIOS is causing issues(try disabling this option)
  • Old firmware, make sure the drive is on the latest firmware
  • And finally, you may just have a bad drive

# SATA Drives Not Shown in DiskUtility

  • Make sure SATA Mode is AHCI in bios
  • Certain SATA controllers may not be officially supported by macOS, for these cases you'll want to grab CtlnaAHCIPort.kext

# Stuck at 2 minutes remaining

This error is directly related to the stage at which macOS will write certain NVRAM variables for your system to boot next, and so when there's issues revolving around NVRAM it'll stall here.

To resolve, we have a few options:

  • 300 series Intel Fix(ie. Z390):
  • Others can set the following in their config.plist:
    • LegacyEnable -> YES
    • LegacyOverwrite -> YES
    • WriteFlash -> YES

# The recovery server cannot get contacted

If you made your installer in Windows or Linux, then this means your USB installer is recovery based. What this means is that only a small portion of the macOS installer is on disk while the rest must be downloaded from Apple servers in the installer. And reason we do not include full installer guides is due to unstable HFS drivers and other utilities that commonly end up with data corruption.

To resolve the error, you have a few options:

  • Ensure you have a working Ethernet or Wifi connection
    • Open Network Utility under Utilties header in the installer and see if your Network Card shows up
      • If you network card doesn't show up, it's likely you're missing the right Network kext
      • If the network card does show up, next run ping -c3 www.google.com in the installer's terminal to ensure your network connection is working
        • If nothing shows, either your network or kexts are acting up
          • We recommend trying older variants of kexts in cases where newer builds have weird bugs with your hardware
        • If it does return something, then the issue is on Apple's end. You'll simply need to try to install again another time unfortunately

# Keyboard and Mouse broken in Big Sur

For certain legacy systems(ie. Core2 Duo/2010 and older), you may notice that while the USB ports work your HID-based devices such as the keyboard and mouse may be broken. To resolve this, add the following patch:

IOHIDFamily Patch

config.plist -> Kernel -> Patch:

Key Type Value
Base String _isSingleUser
Count Integer 1
Enabled Boolean True
Find Data
Identifier String com.apple.iokit.IOHIDFamily

Mask Data
MaxKernel String
MinKernel String 20.0.0
