[HOW TO] OpenCore 0.6.5 > 0.6.6 differences

[agrajag]

Thank you @miliuco for this hint. Problem was caused by "old" HfsPlus.efi driver located in Drivers folder together with OpenHfsPlus.efi. I replaced it by OpenHfsPlus.efi and system is booting correctly now.

EDIT - new workng HfsPlus.efi driver for OC 0.6.6 can be also downloaded from this location : https://github.com/acidanthera/OcBinaryData/blob/master/Drivers/HfsPlus.efi

Note that this driver is from Feb 29, 2020, so not new with 0.6.6

But HfsPlus doesn't belong tu OpenCore package, it doesn't have correlative version with OpenCore like the other drivers that are part of the package.

Updated to 0.6.6.
Tried booting with OpenHfsPlus.efi....wouldn't boot...incompatible driver message.

Then used HfsPlus from the current 0.6.6 OC package, and boot up just fine.

Another who has had a problem with these drivers.
It seems that OpenHfsPlus has yet to mature or that HfsPlus works better on some systems.

Note: remember that, if you boot Windows from OC, to prevent OC from injecting ACPI values you have to act on these keys in config.plist:

• Kernel> Quirks> CustomSMBIOSGuid> True (default is False)
• PlatformInfo> UpdateSMBIOSMode> Custom (default is Create).

Thanks
It's not even mentioned in the Dortania's Multiboot Guide, is it ?

It’s a bit hidden.

• CustomSMBIOSGuid: NO
  • Performs GUID patching for UpdateSMBIOSMode set to Custom. Usually relevant for Dell laptops
  • Enabling this quirk with UpdateSMBIOSMode Custom mode can also disable SMBIOS injection into "non-Apple" OSes...

Desktop Coffee Lake | OpenCore Install Guide

In the OpenCore configuration PDF you can read:

• CustomSMBIOSGuid: Performs GUID patching for UpdateSMBIOSMode Custom mode.
• UpdateSMBIOSMode: Update SMBIOS fields approach:
  Custom: it overwrites firmware SMBIOS contents at ExitBootServices. Otherwise equivalent to Create. Requires patching AppleSmbios.kext and AppleACPIPlatform.kext, done automatically by CustomSMBIOSGuid quirk.
  Note: A side effect of using Custom approach is making SMBIOS updates exclusive to macOS, avoiding a collision with existing Windows activation and custom OEM software.

That Why Brigadier.bat (python script for bootcamp) Wasn't aware of Opencore SMBIOS .....
It's possible to only enable the Kernel's quick and not "UpdateSMBIOSMode" I suppose ...

I do not know. You can try to put CustomSMBIOSGuid=True but UpdateSMBIOSMode=Create instead of Custom. I have not tried it. If you do, comment if it works well.

Well, we already know one more thing.

Windows from OpenCore:

• CustomSMBIOSGuid: True
• UpdateSMBIOSMode: Custom.
  

Windows Bootcamp from OpenCore:

• CustomSMBIOSGuid: True
• UpdateSMBIOSMode: Create.

Thanks for trying it.
