opencore?

 

https://dortania.github.io/OpenCore-Desktop-Guide/troubleshooting/troubleshooting.html#cant-see-macos-partitions

Yes. I tried that fix but it did not work. Thanks for the suggestion. I am going to try to run the Vanilla big sur usb installer in my other hackintosh a skylake Laptop to see if it sees the internal hd. My problem in big sur of not seeing the internal hdd and internal ssd is with my kabylake laptop with i5-7200u (maybe it’s a kaby lake problem). Thanks!

Yeah, the strange thing is that OpenCore and Clover both see the internal drives but the Big Sur operating system does not.  In fact, during boot up, it takes a long time because the OS is looking for the drives that the boot loader says are there but the OS can't find them.

I'm having this problem with a Kabylake-R laptop but someone else who posted about this problem today said he had it with a Skylake laptop.

On my old legacy BIOS MB,

I need "Fix Hot-plug for ICH10" to patch AppleAHCIPort, after the patch I can use the other internal disk on Mojave, Catalina, Big Sur.

Hi all! Reading all your posts, helped me very much. I attach my fully functional EFI for HP Probook 4540s. Maybe is useful for somebody. Pure vanilla, all working, including recovery boot. Thank you all, but mostly to Rehabman! His amazing work is functional (adapted, yes) after so many years. Cheers!

I am trying to follow the new video tutorial for WiFi on unsupported macs. How can i boot into Big Sur's recovery? Or is this not possible on hacks / OpenCore?

 

I set UEFI/APFS/JumpstartHotPlug to YES in OC config.plist (as recommended by this post @applelife.ru) and OC successfully booted to Big Sur Recovery :).

I also tested the process of manually rebuilding kernel collections and prelinkedkernel (eg after new kexts copied to /S/L/E or /L/E) on the Big Sur volume from Recovery...

Notes:

  • Confirm SIP and authenticated root are disabled, then mount the Big_Sur volume as read-write 
csrutil status
csrutil authenticated-root status
mount -uw /Volumes/Big_Sur
  • According to jackluke on the MacRumors Forums, kextcache -i is "required to update the prelinkedkernel" (the old way of doing things) and kmutil is "required to update the BootKernelExtensions.kc" (the new way of doing things) 
kextcache -i /Volumes/Big_Sur
kmutil install --volume-root /Volumes/Big_Sur --update-all --force
  • The way you control kcditto's *destination* is by choosing which volume you run it *from* ie must use /Volumes/Big_Sur/usr/sbin/kcditto to copy files to Big_Sur volume 
/Volumes/Big_Sur/usr/sbin/kcditto
  • To create a boot-able APFS snapshot (I elected not to), add extra step in terminal bless --folder /Volumes/Big_Sur/System/Library/CoreServices --bootefi --create-snapshot.

Checking date stamps on /S/L/KernelCollections and /S/L/PrelinkedKernels confirms kcditto copied the new kc and prelinkedkernel into place correctly on the Big Sur volume...

Whoa ! Seriously didn’t expect it to be that easy and smooth to update my current Catalina partition to Big Sur in a matter of minutes on my Dell Skylake laptop !

 

All I had to do was replace Lilu with latest “debug” version along with latest master builds of WEG and VirtualSMC, that’s it ! Didn’t even have to modify or edit my existing OC config.plist either ! Booted the Big Sur install media off my external HDD, tapped update directly onto my internal Catalina SSD partition and voila !
Update and install process smoothly took only about the usual 20 minutes with one additional reboot. Everything works just like it did on Catalina except for DRM/Netflix and the Trackpad preferences.

 

Massive respect to all developers and contributors for having reached this far of a milestone with the OC development.

No need to patch installer if your SMBIOS is officially supported in Big Sur (that patch is to allow install into older Macs, bypassing compatibility checks).

 

IIRC, I only saw Preboot booting into the second stage install (the one with approx 30 minutes remaining).  The final boot into the third stage shows only the Big Sur volume to boot from the OpenCore menu.  Interrupting half way through the loading bar during this stage (when the progress bar slows to a crawl and the snapshot is being created) ---> Restart to OpenCore Menu now shows both "macOS Installer" and the Big Sur volume ---> Choose Big Sur Volume ---> 1 reboot, keep on choosing Big Sur volume, not the installer.

 

For those getting error 66 trying to mount their root volume despite disabling SIP for authenticated root --> it means your system still has APFS System Snapshots enabled.  These can be removed following the steps below (credit to guide on reddit) 

 

Fixing APFS Snapshot Procedure

  1. Boot into the Big Sur installer USB
  2. Open a terminal, type `csrutil disable` and reboot
  3. When back into the installer, run `diskutil list` to find the location of the "Macintosh HD" disk, such as disk2s5
  4. Mount it using `diskutil mountDisk <disk identifier>` such as `diskutil mountDisk disk2s5` then run `mount -uw <volume mount point>` such as `mount -uw /Volumes/Macintosh\ HD/` to mount it as read write
  5. Run `/System/Library/Filesystems/apfs.fs/Contents/Resources/apfs_systemsnapshot -v <volume mount point> -r ""`
  6. Then, to delete the snapshots on the disk, run `diskutil apfs listSnapshots <volume mount point>` and take note of each UUID of the snapshots
  7. Run `diskutil apfs deleteSnapshot <volume mount point> -uuid <uuid of snapshot>` for all snapshots on the disk.
  8. Verify that there are no more snapshots by running `diskutil apfs listSnapshots <volume mount point>` it should return "No Snapshots for disk"
  9. Reboot into the Big Sur desktop and make sure that running `sudo mount -uw /` returns no errors and that running `diskutil info /` returns a disk such as disk2s5 and not a snapshot such as disk2s5s1

 

 

 

Here is actual real world example (output from terminal after booting into Big Sur Recovery or USB Installer).  Note in this example, <volume mount point> was /Volumes/Big_Sur,

UUID of snapshot was DD99DFC1-7FA2-4B1E-9F75-04380B0AFCA4...

-bash-3.2# csrutil authenticated-root status
Authenticated Root status: enabled
-bash-3.2# csrutil authenticated-root disable

//After rebooting back into the Big Sur Recovery or USB Installer, open terminal again and check SIP status now disabled...

I tried to install the WiFi io80211family kext and create the snapshot to install the next without luck. I’ll try later on as this requires various and if I do one incorrect it will not work.

I set UEFI/APFS/JumpstartHotPlug to YES in OC config.plist (as recommended by this post @applelife.ru) and OC successfully booted to Big Sur Recovery :).

I also tested the process of manually rebuilding kernel collections and prelinkedkernel (eg after new kexts copied to /S/L/E or /L/E) on the Big Sur volume from Recovery...

Notes:

  • Confirm SIP and authenticated root are disabled, then mount the Big_Sur volume as read-write 

csrutil status
csrutil authenticated-root status
mount -uw /Volumes/Big_Sur
  • According to jackluke on the MacRumors Forums, kextcache -i is "required to update the prelinkedkernel" (the old way of doing things) and kmutil is "required to update the BootKernelExtensions.kc" (the new way of doing things) 

kextcache -i /Volumes/Big_Sur
kmutil install --volume-root /Volumes/Big_Sur --update-all --force
  • The way you control kcditto's *destination* is by choosing which volume you run it *from* ie must use /Volumes/Big_Sur/usr/sbin/kcditto to copy files to Big_Sur volume 

/Volumes/Big_Sur/usr/sbin/kcditto
  • To create a boot-able APFS snapshot (I elected not to), add extra step in terminal bless --folder /Volumes/Big_Sur/System/Library/CoreServices --bootefi --create-snapshot.

Checking date stamps on /S/L/KernelCollections and /S/L/PrelinkedKernels confirms kcditto copied the new kc and prelinkedkernel into place correctly on the Big Sur volume...

how to rebuilding kernel collections and prelinkedkernel after new kexts copied to /S/L/E or /L/E) under the Big Sur using terminal without recovery

and how to copy kext to /L/E or /S/L/E

With iMac 15,1 I can't see anything DRM protected anywhere (VideoProc hevc not supported h264 not supported)

Using iMacPro 1,1 I can see AppleTV and NetFlix on chrome (VideoProc hevc supported h264 supported)

But using safari I just get a red screen and using AppleTV app a green striped screen (audio works on both)

Old movies bought from iTunes when played on the AppleTV app show just a red screen as NetFlix.

Yes, it's just a small problem, but fixing problems  its the fun part of making an hackintosh :)

If I wanna watch DRM stuff I'll just use chrome!

Obviously if someone find a fix it would be great!

Without this kext WIFI not working here 

I  see my way out is not relate to this kext for me

Hello @chris1111 and all hackintoshers. I read the following in the read me of airportbrcmfixup GitHub: 

 

Remove injectors for AirPortBrcm4360 and AirPortBrcmNIC from main Info.plist and move them into separate plugins AirPortBrcm4360_Injector and AirPortBrcmNIC_Injector (kexts with plist only). 
Under 10.16 (Big Sur) plugin AirPortBrcm4360_Injector.kext must be blocked by MaxKernel 19.9.9 or just removed, otherwise it will block loading of AirPortBrcmNIC since class AirPortBrcm4360 is unsupported.

 

My question is how I block the injector by MaxKernel 19.9.9 in the config file kernel section? I was looking for some examples but couldn’t find one. Would this be enough to fix compatibility of WiFi BRCM94331 card? Or do we still need to install the io80211family.kext attached to one of the posts attached to this thread?

I only yesterday was able to fix my HEVC problem, but I can't play Netflix in safari or firefox, only in Edge, Chrome I don't use.

How is that possible @Pavo, it is a combination of right SMBIOS and graphic id's?
