Ha-ha. Native Apple Bless protocol works 100%. Tried to update your AMI firmware with Apple ROM

 

It happened because of outdated Apple Boot ROM version in OpenCore. Either you use outdated BIOSVersion with Automatic-false in PlatformInfo->SMBIOS, or (if you use Automatic=true) BIOSVersion in OpenCore sources are outdated.  

So perfect. Updated to 10.13.6 2019-006 today and didn’t need to touch anything. Startup disk assignments were handled perfectly by OC bless. Thank you!

I was also interested in using OC only with Custom Entries  ( Hiding the "Recovery" options for all OSX versions in the picker ). I was able to able to boot from the custom entries on APFS formatted drives ( NVMe & SATA ) on both Mojave & Catalina. ( see path below, taken from OC Bootlog ) However If I don't add the APFS Scan ( bit 8 ), the entries appear in the bootpicker but the image cannot be loaded. I tried several options.

At this point Custom entries for OSX become irrelevant because OSX will appear in the picker regardless.

I wish OC had an option to hide specific volumes...Maybe someone has an idea to go around it?

 

You can select which default volume to boot by going into System Preference -> Startup Disk -> Select the system you want to use to start up your computer.

i got kernel panic on shutdown so it won't shut instead doing reboot (on Clover it's not a problem)

here i attach my OC Folder and the panic message

hope someone could help my problem

@aziiz3 I suspect they use Aptio 5? Then you probably use EmuVariable in Clover and want DisableVariableWrite in OC

Hello,

 

where can i get memcheck.efi ?

[mhaeuser]

@Quipper I have never heard of that app and this has absolutely nothing to do with OpenCore...?

[DonBronko]

In sample.plist of OpenCore is a memory testing utility listed.

I wounder how can i activate it.

 

[Noir0SX]

Enabled YES

[mhaeuser]

@The_Dave94 Probably a kext declaration with a missing ExecutablePath, but my crystal ball doesn't work well right now, sorry

[Thegn]

**** Edit: Solved ****

I disabled CSM, and I think that was what made it work.

I also generated a new DSDT.aml from Clover.

Audio works, Radeon VII works. Doing some cosmetics, adding device properties so the hardware shows under PCI in System Profiler.

I will probably move from Clover to OpenCore after some testing. Thank's devs!

Hi everyone,

 

I wonder if someone would like to help me with moving from Clover to OpenCore. I spent several hours reading about the installation and trying to get my OC USB boot into Catalina 10.15.1 without success. All works very well with Clover, but obviously I'm configuring OC wrong in some way.

 

My system: Maximus Formula VIII with a Core i7-6700K, 64GB RAM, AMD Radeon VII. I've disabled the iGPU in BIOS [Settings to: PEG] because I'm using SMBIOS iMacPro1,1 which I've read is the best when using Radeon VII.

Running OC build 0.5.3 built October 31.

 

What I tried so far:

Running with and without ACPI EC, USB .aml files

Using and not usingUSBInjectAll.

Tested to patch AppleRTC, and not.

Using agdpmod=pikera, and not.

 

The system hangs shortly After "com.apple.AppleFSCompressionTypeDataless load succeeded", which I've read somewhere could be something relating to graphics issues, because it starts to load after that. But I don't know what I can do more about the graphics configuration then run the latest WEG and trying with/without agdpmod=pikera.

 

I've attached my OC config.plist and an image from about where it hangs.

 

Grateful if someone could provide me with a solution or tips that can help me!

Cheers,

I already know that but that's not what I'm trying to achieve. I wish to hide specific volumes that have either some versions of OSX or their recovery partition; so the picker shows me only exactly what I want & in a specific order .

OpenCore shows everything bootable in the sense of what it considers bootable (i.e. macOS by bless and standard UEFI path). If you do not want to boot something, do not have it bootable, which will also save you a bit of storage space.

Because I already have dedicated drives with Vanilla installs of OSX, I really don't care about the recovery partition.  Are you suggesting that I can delete it safely?

@Ellybz If you are not going to use HFSPlus with FileVault 2, I wouldn't know why not at the moment. Just re-create it if you ever need it

Hello, OpenCore is giving me this error "Found legacy AptioMemoryFix driver!" but I'm using the one bundled in the latest package (v0.5.1). Anybody knows how to help me? Thanks a lot.

EFI.zip

 

Does anyone have any idea? Thanks

Edited November 3, 2019 by Cesco92

[UefiBooter]

Umm only official binary packages are supported and AptioMemoryix driver isnt part of that, so check your using the binaries from https://github.com/acidanthera

 

AptioMemoryFix functions have been moved into OpenCore and FWRuntimeServices now.

Updated to  OC 0.5.2, brilliant. No more random cursor and faster boot.

 

What need to be set to see the output of VerifyMsrE2? I can launch it, but the screen remains black for a few seconds and then returns to the boot manager...

 

Thanks!

Added boot screen support to VerifyMsrE2 in AppleSupport master. This should let it launch from OpenCore menu.

I just did the switch from Clover to OpenCore myself. I spent perhaps around 10 hours reading, grinding and failing before it worked for me.

 

I hope someone will help, but in the meantime, I suggest you read some guides on OC. There are guides corresponding to different intel chipsets, for instance. Find your match if you can, and read to get to know more about OpenCore. It is very different from Clover, albeit there are similarities and things you could perhaps reuse in your configuration. It is good to have the knowledge about OpenCore the day when you need to upgrade your OpenCore installation.

 

Also, at first, install OpenCore on a USB stick and try to boot from it. In that way, you still have Clover left on your EFI harddrive and can boot from it if OpenCore fails.

 

Hope it works out!

Cheers,

On my ProBook in my signature i use a RTC patch from rehabman to avoid rtc battery error on startup.

Is it possible to replace that patch with a ssdt?

 

 

DSDT.aml

[yehia2amer]

I am trying to boot from OpenCore version 0.5.2, but i am getting this error:

 

OC: Failed to open root FS - Security Violation!

 

Tried to search in the docs, but found nothing, any Ideas what this error means ?

Hi,

 

I got OpenCore booting, and I now want to do all the correct SSDT's. According to the Vanilla Guide, I should use two SSDT's (I have an ASUS Maximus Formula VIII, so Skylake it is):

 

1. SSDT-PLUG

2. SSTD-EC-USBX

 

The guide says one could use the SSDTTime script for the EC part, but as far as I understand, it only makes a SSTD-EC.aml, NOT a SSTD-EC-USBX.aml?

 

Also, I'm a bit confused about all the EC renaming, as the SSDT-EC-USBX.dsl says we should not rename from EC0, H_EC, etc. to EC?

 

How should I proceed to make a correct SSDT/SSDT's for my Skylake Asus Maximus Formula VII running Catalina?

 

Glad for any help!

Cheers,
