Rev 5119 commit cd2318129, 60901993b Now OcQuirks.plist excluded because it embedded to config.plist as section "Quirks". See config-sample.plist. Moreover there is a menu to tune the set of quirks from Clover GUI

Disable authenticated root SIP by setting csr-active-config to 77080000 in OC's config.plist, then reset NVRAM through the OC boot menu. Alternatively, with blank csr-active-config setting, boot to Recovery/Big Sur Installer and run csrutil disable, then csrutil authenticated-root disable in terminal Need to also disable APFS snapshots. I posted a guide several pages ago on how to do this and also replace/installing old kexts. Good Luck!

Set UEFI/APFS/JumpstartHotPlug to YES/True in config.plist.

Worked perfect on my rig and is now the default setting in my config.plist going forward.

@MorenoAv to be quite honest I haven't done anything special to my config.plist for windows, it just shows up automatically - Here is my config.plist minus personal data for you to compare. config.plist

Finally, my i3-2100 legacy BIOS with GT640 works fine on Big Sur now. I use VMware method to install Big Sur beta 2. After installed, boot to Big Sur system fine with OC 0.6.0 and Clover (someone's CLOVERX64.efi) ---- It's unknow issue....still. Stage 2 still get reboot after Apple logo if install directly with OC 0.6.0. (not VMware method) System is shutting down, (SIP is Disabled) allowing process at path: /System/Library/Extensions/IOGraphicsFamily.kext/iogdiagnose

thanks great job @lvs1974 finally have been fixed SMCBatteryManager by lvs1974 i compiled latest commit changes of https://github.com/acidanthera/VirtualSMC/tree/smcbat_bigsur_adaptation SMCBatteryManager.kext Worked perfectly once again thanks and great job credit goes to @lvs1974 VirtualSMC-1.1.5-RELEASE.zip

Injector kext (ones without a ExecutablePath) do not show up in kextstat, you need to check IORegistryViewer to see if it loaded, For example AGPMInjector below:

Could you add your hardware specs to your signature? Attached my EFI folder minus resource folder and minus serial numbers. This works 100% on my laptop in my signature. EFI.zip

Try 77080000 I think (in ProperTree). I may be wrong but I think that’s what I’m using and I still get error 66. I didn’t delete apfs snapshots, left it vanilla, that could be why I still get error 66. I’ll upload my config later. Sent from my iPhone using Tapatalk

-lilubetaall & vsmcgen=1 are no longer needed as long as you have updated your kexts. Have you tried minimizing your config? Remove some .aml, kexts, device properties? I don't have x299 so these are just suggestions.

Sorry for the late. Both the app and the pkg updated to deal with OcStuff, OpenRuntime get installed among OcQuirks and the plist should be installed if missing. P.S. sorry, untested here as it's late but testers are welcome from both the installers.

Just wanted to say thanks for the Opencore setup. I thought i would spend hours being frustrated as i read multi booting can be a pain. However i am shocked at how easy it was first of all to switch from clover to opencore (i only got a re-sign in error guess cos i never had a MLB key in clover so did not set one in OC) however sign in and all syncing fine. Was then surprised to see the retro gaming Windows setup appear in boot options with no fiddling (separate NVME drive). Main Windows was missing, but just copied the microsoft folder from efi backup to main OC efi, rebooted and boom now have 2 windows installs showing. The holy grail for me which for some reason i kept borking on Clover was getting linux to show. However just installed Ubuntu 20 to a separate SSD and after realising i kept plugging the ssd in Sata 4 or 5 which wont show once you reconnec 2 NVME drives in (0-3 only) Opencore immediately showed all 4 OS. yes it shows it as no name instead of Ubuntu but im not worried about Cosmetics. So i must firstly thank you guys for the smoothest of setups both originally on Clover but especially on OpenCore, however i must alas berate you at the same time, as i was all geared up to be in a stressed mode this afternoon, ready to have a serious gym work out by throwing my build around the room until it decided it was best to just start working, you took that from me by doing such a bloody good job, so instead i now have to play rage against the machine extremely loud and find something else to rage about.

This project is dedicated to Lucy, my lovely little Tyrannofelis Rex. LucyRTL8125Ethernet is an open source driver for the Realtek RTL8125 family of 2.5GBit Ethernet controllers. Key Features of the Driver Supports all versions of Realtek's RTL8125 2.5GBit Ethernet Controllers found on recent boards. Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission. No-copy receive and transmit. Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. TCP, UDP and IPv4 checksum offload (receive and transmit). TCP segmentation offload over IPv4 and IPv6. Support for TCP/IPv4, UDP/IPv4, TCP/IPv6 and UDP/IPv6 checksum offload. Supports jumbo frames up to 9000 bytes (strongly recommended for 2.5GBit operation). Fully optimized for Mojave and above. Note that older versions of macOS might not support 2.5GB Ethernet. Supports Wake on LAN (untested). Supports VLAN (untested). Support for Energy Efficient Ethernet (EEE) which can be disabled by setting enableEEE to NO in the drivers Info.plist without rebuild. The default is YES. The driver is published under GPLv2. Current Status The driver has been tested successfully under Catalina (10.15.4 and above) and, according to first tests, is working stable. I haven't experienced any Kernel Panics during my tests and is working stable on my primary work machine. The driver has been designed to work with Catalina but might also work with Mojave, provided you build from source with Xcode 10.. Please keep in mind that support for 2.5GBit Ethernet was introduced in Mojave (or maybe High Sierra?) so that there is no way to make it work with Sierra or below. Known Issues Using autoselect medium it seems to prefer negotiating a connection speed of 1Gbit with my switch so that I had to select 2.5GBit/s manually in order to achieve this speed but it might be different with other switches. This problem has been resolved in version 1.1.0. Installation You might want to install the driver to /L/E as usual but it's also ok to use Clover's or OC's injection function (installation in the EFI folder). Use your favorite kext installation tool for installation or perform the installation manually (for Clover or OC injection). It's your call! Help - I'm getting kernel panics! Well, before you start complaining about bugs after you upgraded macOS and ask me to publish a driver update, you should first try to resolve the issue on your own by cleaning the system caches. As the driver uses macOS's private network driver interface, which is supposed to be used by Apple provided drivers only, you might run into problems after an OS update because the linker may fail to recognize that IONetworking.kext has been updated and that the driver needs to be linked against the new version (Apple provided drivers avoid this problem because they are always updated together with IONetworking.kext). As a result, the linking process produces garbage and the driver may call arbitrary code when trying to call functions from IONetworking.kext. This usually results in unpredicted behavior or a kernel panic. In order to recover from such a situation, you should clean the System Caches forcing the linker to recreate it's caches: Delete all the files in /System/Library/Caches and it's subdirectories but leave the directories and the symbolic links intact. This is very important! Reboot. Recreate the kernel cache. Reboot again. Troubleshooting Make sure you have followed the installation instructions especially when you have issues with certain domains while the others are working fine. Use the debug version to collect log data when trying to track down problems. The kernel log messages can be retrieved with "log show --predicate "processID == 0" --debug" in order to retrieve kernel logs. Include the log data when asking for support or giving feedback. I'm an engineer, not a clairvoyant. Don't copy and paste large amounts of log data to your post. Create an archive with the log data and attach it to your post. In case you don't want to make your log data publicly accessible, contact me via PM and I will provide you a mail address to send it directly to me. Delete the following files: /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist /Library/Preferences/SystemConfiguration/preferences.plist In Terminal run netstat -s in order to display network statistics. Carefully examine the data for any unusual activity like a high number of packets with bad IP header checksums, etc. In case auto-configuration of the link layer connection doesn't work it might be necessary to select the medium manually in System Preferences under Network for the interface. Use Wireshark to create a packet dump in order to collect diagnostic information. Keep in mind that there are many manufacturers of network equipment. Although Ethernet is an IEEE standard, different implementations may show different behavior causing incompatibilities. In case you are having trouble try a different switch or a different cable. Changelog Version 1.1.0 (2021-04-29) Changed version number to 1.1.0 to make it an official release. Version 1.1.0d12 (2021-04-25) Updated Linux sources to 9.005.01. Fixed auto-negotiation for all speeds (including 2.5 Gigabit). Added support for adaptive poll interval in 2.5 Gigabit mode. Version 1.0.0 (2020-08-14) Changed version number to make this the first official release. Version 1.0.0d6 (2020-06-14) Fixed chip recognition. Version 1.0.0d3 (2020-04-20) First working development release.

Hi @MorenoAv, Just a few tid bits on dual booting macOS and Windows with OC... 1. Since 0.5.9, OC can automatically detect UEFI Windows loader bootmgfw.efi --> no need for Custom Entry 2. From OC documentation (Configuration.pdf) re OEM Windows activation... "Windows may need to be reactivated. To avoid it consider setting SystemUUID to the original firmware UUID. Be warned, on old firmwares it may be invalid, i.e. not random. In case you still have issues, consider using HWID or KMS38 license or making the use Custom UpdateSMBIOSMode." Personally, I set Kernel/Quirks/CustomSMBIOSGuid to YES and PlatformInfo/UpdateSMBIOSMode to Custom in my OC config.plist ---> avoids Windows OEM activation problem (Windows keeps its original firmware UUID and macOS keeps its own SystemUUID). PS I moved my reply here since I think it would be off topic in the Big Sur beta thread

Yep it's not activated... but is the correct way to d it...

Try this: Which will copy the PciRoot identifiers for all the recognized partitions, including your Windows/macOS EFI partition. Now back on your other machine, open up the OpenCore config.plist and the maps.txt file we generated in the previous step. In the config.plist, find this entry: \EFI\Microsoft\Boot\bootmgfw.efi so that your Path looks this: Now when you boot up OC using this config.plist, you should see the name you've specified in the custom entry and using that, you should be able to boot into your Windows installation. You need put Microsoft folder inside EFI partition too. Mine is for Windows 7...(im believe that you need install Windows # and then are created by it self on installation... <FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF> is your UUID. With Clover Configurator you can see this on partitions... Microsoft.zip For exemple:

In RtVariables/CsrActiveConfig, set to 0x0877... <key>CsrActiveConfig</key> <string>0x0877</string> You can use modifed Clover r5119 from post#1 to boot already installed Big_Sur volume.

I didn't quite understand - Is this what you're asking about? Because if you look through the config.list I posted you'll see this exact default entry which is not enabled.

Smooth as butter!

Hi guys good afternoon... Quick question for @eSaF, the entry below in your config.plist is what makes widows boot successfully? Thanks

unfortunately this kext didn't work for me.

@Sbrillo Check out this guide... https://dortania.github.io/OpenCore-Desktop-Guide/extras/gui.html?h=opencanopy

To get Apple TV+ to work I had to change my System Product Name to iMacPro1,1

You need to remove all the five lines.

Any one having Big Sur working on a X99 platform? Thank you in advance

thank you so much for hard work[emoji3] 나의 SM-N960N 의 Tapatalk에서 보냄

Answered in other thread. Don't double, I see anyway.

First, boot to Recovery or your Big_Sur USB installer Type in terminal diskutil mountDisk1s5 Then mount -uw "/Volumes/BigSur II" since you have spaces in your Big_Sur volume name. Also hint for using terminal: you can type some letters of a file path, then press <Tab> button and it will autocomplete Already posted it back here.

agree try use 77080000 pico@picos-iMac ~ % csrutil status System Integrity Protection status: disabled (Apple Internal). pico@picos-iMac ~ % csrutil authenticated-root status Authenticated Root status: disabled pico@picos-iMac ~ %

I was abled to boot into the Big Sur Recovery Partition without any issues whatsoever after setting 'JumpstartHotPlug' as true, as a matter of fact, I now have 'true' as the default setting going forward. I must add, no other setting was made to the config.plist to invoke this.

I am using BT4LEContinuityFixup.kext for that. Dont forget to update your config.plist BT4LEContinuityFixup.kext.zip

We were discussing AirportBrcmFixup and its plugins which i put in the correct order. If there are other issues in his config i didn't look at it.

I edited the DeviceProperties to add what i have in config.plist and i also added the plugins for the new AirportBrcmFixup.kext to the config.plist. You can try it as long as you add in your serials etc or copy over what i added / changed into your config.plist What WiFi chip do you have?

This one has the deviceproperties and plugins for AirportBrcmFixup. config 2.plist This is assuming you have vanilla kexts in S/L/E

No, the main point of the post was that it is possible to boot Big Sur on an old machine with a non metal graphics card as long as the OS is already fully installed on the HD/SSD. Without a metal capable graphics card, I was unable to install from scratch with a createinstallmedia Installer USB (installation stalls at stage 2, kernel panics with graphics error ---> reboots). 1. Ensure SIP, authenticated-root and APFS snapshots are disabled.

The end result of installing kexts and rebuilding caches while booted into Big Sur seems to be that KernelExtensions.kcs are updated but the prelinkedkernel remains unchanged, compared to doing this process from Recovery where both the prelinkedkernel and kcs are updated...

@jlrycm Use the one attached and use ProperTree to make a snapshot of your OC folder. Depending on the card you have you may also need to add this to your config.plist under DeviceProperties (change the compatible value if needed) <dict> <key>AAPL,slot-name</key> <string>WLAN</string> <key>compatible</key> <string>pci14e4,43a0</string> <key>device_type</key> <string>AirPort Extreme</string> <key>model</key> <string>Broadcom Brcm43xx Wireless Network Adapter</string> <key>name</key> <string>AirPort Controller</string> <key>pci-aspm-default</key> <integer>0</integer> </dict> AirportBrcmFixup.kext.zip ProperTree.zip

yes, you can install it but it doesn’t have graphics acceleration yet. we’ll have to wait and hope someone can get the hd3000 working

I have fix this issue

https://github.com/acidanthera/bugtracker/issues/1034#issuecomment-656701712 Its a known issue when using WEG.

@Slice Thanks for committing '50a98dc4f', it' s built fine now. CloverBuild-r5119-50a98dc4f-AOH.txt.zip

fix mistakes of previous commits

You need to find out what make it is. Elan, Synaptics or i2c. Then you can troubleshoot. Voodoops2 is a good choice as long as it’s loaded correctly with OpenCore, you could also try ApplePS2SmartTouchpad, google will help find it. What are you doing “snapshots” with? Posting an IOReg and your config.plist (minus serial numbers / rom / mlb) will help too. Mount EFI partition, copy EFI folder to desktop to modify before uploading (do not modify your hard drives config) also debloat your EFI folder, resources etc are not needed for diagnosis.

give me some time and i will try it, i need to wait for usb installer to be ready and then i need to backup all my hackintosh stuff. I will try it on my x99 hackintosh, but i think I should also try it also on my socket 1150 machine which is probably the best hackintosh i have right now (except for the nvidia gpu)
