[pre-release] macOS Big Sur

[MorenoAv]

Anyone of you have the new Lilu, build from master?

 

Back from one more fresh install, the last one was gone at the first reboot, the apple logo appears and the loading bar was grey and empty... so I decided to star anew, and here I am...

[SavageAUS]

Even Apple cannot decide what version this is.

No luck here but I have made some advances in my understanding of the problem.  The problem lies with the new AHCIFamily.kext and more particularly the IOAHCIBlockStorageDriver.kext.  It simply cannot read the internal drive information.  I tried using the AHCIPortInjector.kext but it did not solve the problem.  The problem is NOT that it cannot read internal vs. external drives.  The problem is that Big Sur cannot read SATA drives (i.e., drives physically connected to PRT.). You can see this if you use IORegExplorer.  I am thinking that this problem is not related to our hardware but I can't say for sure.  I have the Intel Series 10 chipset.  I have a custom DSDT and, among other things, I changed all references from SAT0 to SATA.  Without my custom DSDT, I cannot boot to Big Sur at all so I can't really test whether the problem is in some DSDT patch(es).  I also tried changing the SMBIOS from my usual MBP14,3 to iMac19,2 but also without success.  I was thinking that Apple might not allow internal drives that do not belong on that Mac model.   I may still try some type of MacPro since it can have a variety of internal drives.  I was asked by @SavageAUS if I could use a hot-plug SATA port but alas, my laptop does not have one to test that out.  BTW, my BIOS has very few options but, by default, it is set to AHCI, not IDE or RAID.  In fact, there is no option to change the SATA settings.  That's where I am so far.  I have not given up but I have spent way too many hours this month not working so that I could try to figure this out.

i solved now internal disk is appeared and clean installed using usb installer

if you using kabylake Sunrise point-Lp SATA Controller 8086 9d03 then remove SATA patch from DSDT and SSDT and config  no need patch

because 8086 9d03 SATA Controller nativelly supported

Unless it's only me, be careful with the new updated kexts. I now cannot boot back into my Catalina install but Big Sur still works.

I got caught in the boot loop doing the install over beta 1 so I decided to make a USB installer with Beta 2, doing some work with the EFI, the USB installer booted and I was able to install a fresh copy onto a SSD, all working now, I did have to select RESET NVRAM after copying the EFI folder from the USB to the SSD but after that it booted fine.

 

Everything working on the HP 800 G1

Unfortunately none of those won’t fit in my specific laptop. Not much room.

Was just looking at a bcm94360ng, will that work with BS and below?

Here. Folder for Skylake+. in some cases need change things in Booter Quirks

EFI BigSur Skylake+.zip

Some observations

Boot from USB / Disable booter-fileset-kernel and booter-fileset-basesystem

Boot from SSD / Enable these options if need

Work in beta 2 too

Create your USB stick with createinstallmedia and paste this EFI folder into EFI partition, reboot, Reset Nvram

 

Thanks for this. Installed Big Sure Beta 2 on my Thinkpad X260 using your OC config and then booted via modded Clover 5119 (I dual boot Windows so Clover works better for me). Everything working 100%, only issue was with SMCBatteryManager so I reverted to ACPIBatteryManager until it gets sorted.

 

I'm attaching my EFI folder for the Thinkpad X260 i7-6600u with Bios 1.43.

I will convince today but this complicated, I do not want to test on other machines but on my Dell Vostro 2520 intel i3-3110M HD4000 with a restore dmg to HDD works normal but for clean installation from my USB Install it blocks after starting all the install and impossible to continue because it makes me a KP! thank you for your answers

What is run-efu-update into the old config.plist ???

[dariuxzy]

Thanks to @Cyberdevs's efi and @eSaF's help, I managed to make beta 2 work! Since I'm on laptop (haswel), if I insert the kext for keyboard and touchbar with OC, there is a kernel panic (VoodooInput). Thanks for your help

 

EDIT. I used the latest VoodooPS2 by acidanthera, and everything worked out!

Are there any news regarding atheros wifi cards with beta 2? I tried to insert AirPorAtheros40 on OC, and this time it doesn't crash at startup, but it is not always recognized

Have you tried putting it in the EFI/OC/Kexts folder?

Try this kext and make sure to add it to the config.plist

Thanks, but now it stuck here

well that's because the IO80211Family.kext is already loaded in PrelinkedKernel I guess so you need to remove the original kext and rebuild system and kext caches. or just remove the kext from the EFI folder and look for an alternative solution.

Yes, but how do I mount the partition? With "sudo mount -uw /" it gives me "error 77"

I had, until I fixed my DRM video playing capabilities. It keeps crashing if I try to open a Private window, though - but that was happening on B1 too.
