OpenCore bootloader with development SDK

[PlexiPuter]

What I've ended up doing on OpenCore, is making sure the DSDT I'm running on, is fully renamed.

Then, I put SATA and IGPU in a Kaby and  SATA, IGPU, and HDEF in a Coffee, in as a patch, but I set it to rename just the table SSDT's.

Rename only seems to work on generated tables in OC.

This seems to be the best I can make these two machines run on OpenCore, but they're running spot on!

I know the OC manual states against renames but I didn't put OSX on a Pee Cee to run windoze myself

ssdt is a pseudo solution, is not a full solution

same way work in clover too

[PlexiPuter]

Yep. I like the idea of having eveything working from the DSDT.

Hi Maldon, 

I am trying to replace Clover with Opencore, I have used your Clover EFI and Dsdt , it has been working perfect. But when I try to boot with the Opencore Efi , it stops at "AppleIntelLpssI2CController::_serviceMatchingTimeSubr: fTimerServiceMatching timed out," and  It flashes waiting for Root Device  then scrambled screen. 

 

I didn't change anything from your EFI folder and was using Opencore as legacy. My Laptop supports UEFI but somehow Mac won't boot on UEFI with my battery in. Same case for clover and Opencore.

Hi Maldon

if u have a perfect hack with clover why oc?

 

[Shahzad]

Actually I had some issues

1. Clover takes long time to boot, around 1min or so, and tried to clean it up to make to faster but anything I remove, breaks it so tried oc.

2. My laptop microphone doesnt have proper gain, like I can only hear tapping on the microphone, nothing else. I tried to use some guides to patch it platform.xml files but failed. 
like this one-

https://github.com/F0x1c/AppleALC_Instructions/blob/master/README.md

3. And I always wanted to use Uefi but didn’t know untill trying to work with opencore that its Mac, not the bootloader thats the issue.

use clover instead

[vamoose]

Thanks for your help.

 

can you also suggest, the best video card with 4K resolution for office work/ basic computing .

Should be compatible with Catalina & up for future.

rx590, good price

[vamoose]

Thanks a lot.

I advice to stay on Catalina since google search return without any successful Bigsur installation. Check the link below maybe can help.

Something up with the Coffeelake Desktop version. I tried to boot from the EFI folder on a pendrive. It shows a "No schema..." error which goes away very quickly, too quickly to photograph or screenshot, then the text-only picker shows up. On selecting the HDD to boot from, it reboots and then boots into Mac recovery mode.

I have a Gigabyte Z390 Aorus Master with i9 9900K. Everything working perfectly from your last release of the EFI folder.

i'm using these folders every day and just work fine

in some cases, catalina for example just need check Secure Boot Model

Thanks for this EFI. Works just fine, but as soon as I switch to the imac19,1 SMIOS it starts showing a text-only bootpicker and then there is an apple logo without a progress slider.

Hey @MaLd0n I can't seem to make any changes to this EFI. I am using ProperTree to edit, like get a new serial number, add my USBPorts kext, but even a single letter of change seems to upset everything. What do I need to bear in mind when editing this plist?

im using opencore configurator last version with beta properties or oc auxiliary tool

@MaLd0n Thanks, I did not use OCC because I read in places that it removes certain entries from the config.plist, but I did try OC Auxiliary Tool as well, and same results? I am now trying to get a fully functional MacPro7,1 setup, to take advantage of the 5700 XT and stop using the iGPU on the 9900K. Attached is my fully working EFI for iMac19,1 SMBIOS (removed the tools and resources folders to reduce file-size). I just have the following non-vanilla items:

• A kext to show SDCards inserted into my USB3 Card reader with the Apple-generated icons, not the generic pendrive icons.
• USBPorts kext generated to allow all USB Ports to work. I keep the XHCIPortLimit switch set to true in config.plist and then open the 16 USB2/3 ports I need to have all ports on the front and back of the cabinet working.
• dagpm kext, along with SSDT for RX5700XT performance enhancement as detailed HERE
• I also remove the kexts that I don't need, such as SmallTree, Atheros etc.

But for the life of me, I can't get any combination to work. I am at the verge of giving up.

I‘ve tried to block the IOPCIFamily.kext of Monterey 12.1 beta 4 and load an older Version (Monterey beta 8 in OC, but it doesn‘t work. Would you please explain how to do it?

what hardware? why u need this procedure?

[JaoM]

I need this for the z490 Vision D. The i225v ethernet contoller only works with this version of the kext. Mounting the filesystem (snapshot) in r/w mode and installing the kext to s/l/e works, but it breaks the seal. So i try to block the kext and load the older one.
