You need an already installed BigSur and upgrade (or reinstall) that installation from an USB BigSur Installer to select the "BigSur Data", otherwise only "macOS Installer" is showed.

For BigSur beta4 these still works:

BigSur IvyBridge beta3 prelinkedkernel fix.command.zip

BigSur Penryn beta3 prelinkedkernel fix.command.zip

BigSur beta3 Nvidia Tesla fix.command.zip
Thank you!
I try all 3 patches now.
Beta4 on mac mini 2010 actually boots only from openCoreLoader4 (forbidden symbol) native Wifi doesn't work anymore, no ethernet, no internal sounds, no usb.

Edit: Patched Preboot from BS beta 3 (first fixer)
@jackluke You are my light! Now it boots without openloader, usb OK, wifi status is yellow (?) but detects my hotspots names. No internal sounds or ethernet. With black theme menu bar is completely white. Next step? ?

What method did you use to install
All my Macpro does is boot loop after the files have been put on my ssd via initial install screen
step for macPro with
1. Isntall Opencore
2. Creating Bootable DISK with Bigsur Beta 1
3. patch with big-sur-micropatcher-0.0.17 (dont use 0.0.19)
4. Go to system preferences>startup and choose bottable disk instaler big sur
5. on recovery instaler big sur, open terminal and write this
/Volumes/Image\ Volume/set-vars.sh
6. close terminal and install macos big sur
7. after finish and boot with big sur, and step choose country , shutdown macpro
8. booting with installer
9. open terminal and patch with this script
/Volumes/Image\ Volume/patch-kexts.sh /Volume/NAME OF DISK INSTALLED BIG SUR
10. Done...
.
.
and for update to beta 4, i just download big sur beta 4 and install normal, and after done, just patch again wifi, done
.
.
.
it my step by step

How to D/L macOS Big Sur Installer image (1) As an Apple Developer (2) On an unsupported MBP?

Folks, I'm an Apple Developer and can get to the "download" webpage for the latest macOS Big Sur beta. But the mechanism offered (which involves downloading macOSDeveloperBetaAccessUtility.dmg, installing the utility, and using the standard Software Update tool) fails because I have an "unsupported" MBP 10,1, "Early 2013" (just missed the cutoff, sigh... )

Can anyone recommend an alternate way to download the current BS?4 from official Apple sources (to which I presume I should be entitled since I am a licensed developer)?

TIA,

Mike

Notes:
Tried to find this info in the thread above, but couldn't come up with a fruitful query.
Suggest this info be added to the FAQ at the head of this thread.

Beta 4 successfully installed on my MBP mid 2012 (MacBookPro9,1) with micropatcher version 0.0.18, WiFi works.

I wonder, is the update package the same for all machines ? If you simulate another machine with opencore, don't you risk to have a wrong package ?

This is a 12.3 GB installer package. Looks like all included.

On MacBook 6.1 in IOreg Mojave Tesla looks like this
Снимок экрана 2020-08-06 в 11.22.20.png

There are many TeslаGLContext clients, including not only WindowServer, but other system programs as well.
And in Big Sur, after installing the driver, we only have this
Снимок экрана 2020-08-06 в 11.32.31.png

That is, GPUs without Metal support are almost never used by programs via OpenGL? Does this mean that now the minimal unsupported mac should have mandatory support for Metal, or do we just need to add some other driver for OpenGL to the system?

Are you sure that Tesla acceleration works? I don't see trasparencies on dock and menu bar... My Mac mini 2010 graphic board Nvidia Geforce 320M is similar (newer) to your Geforce 9400M and we have both a Core 2 Duo... I still not have acceleration.
Drivers are loaded, you can look in IOreg and kextstat -l, but the system programs also need to use acceleration through Tesla, but perhaps Apple has already removed this feature from the system. However, the latest version of Mojave work fine, and there is still 32-bit support, so we can stop at this system. Catalina works worse, I often see a spinner in it, and sometimes it wakes up in a black screen, I have to do a rough shutdown. I ditched Catalina, so maybe Mojave is the last good system for MacBooks that don't have Metal support, that makes sense to stay on. Alas.

Thank you. So I understand that incremental updates on unsupported machines via opencore are not recommended.

Not yet, but they already work, for now is advisable using the ASentientBot Hax3 or HaxLib methods and upgrade a previous BigSur installation using the createinstallmedia USB BigSur Installer with https://github.com/barrykn/big-sur-micropatcher .

In few words applying the HaxLib from an USB BigSur Installer environment allows to upgrade a previous BigSur installation, from Catalina desktop you can only install a clean BigSur, probably because of sealed system and snapshot booting, instead both are absent from an USB BigSur Installer booting where you have an unsealed system without snapshot diskXsYs1 volume.

I have a working beta 1, would a patched beta 4 usb upgrade my existing beta 1. Or would it wipe it and install a fresh copy
Upgraded beta 1 would be my choice ?

For Penryn Core2Duo Mac non-APFS or legacy USB , I confirm that this method:

BigSur BaseSystem legacy USB fix

still works for a patched USB BigSur beta4 installer and allows to boot, install and upgrade BigSur on legacy USB Mac on internal SATA disk.

(for external USB disk installation to continue stage2 installer use in addition this: https://forums.macrumors.com/thread...unsupported-macs-thread.2242172/post-28743252)

Also I add that you can combine the @Barry K. Nathan patches with my fixes, I mean they are compatible, moreover adding this: https://github.com/barrykn/big-sur-micropatcher

to an USB BigSur Installer (BaseSystem legacy USB fixed) allows to use correctly his post install script as for example installing kext making a new snapshot or delete snapshots (so you can install kext with "sudo mount -uw /").

The only difference is that I use prelinkedkernel (kextcache) as default kernelcache booting, while @Barry K. Nathan uses kmutil and BootKernelExtensions.kc .

I don’t know what the hell I’m doing wrong but for the last 3-4 days Iv been trying to get sudo mount -uw / to work. None of the patches or methods all me to delete snapshots with ASentientBot method. I check and csrutil and csrutil authentication-root are disabled according to terminal. In the second terminal window I have open it appears it’s mounted as /bs\ 1 but if I run the command it says it failed because it’s read only. And running the command with just /bs says it doesn’t exist.
If you get a chance can you look at the attachment and see if I’m doing something wrong. Thanks

Hi jackluke,
One question about your USBOpenCoreAPFSloader4: Do I need any additional kexts/patches to install Mojave/Catalina? I tried to install Mojave off of a bootable USB through the OpenCore loader and when I go to the window to choose the install disk it says "This version 10.14.6 cannot be installed on this computer" or somethingorother.

Success installing BigSur Beta 4 on Macmini 2010 (Macmini4,1) Core 2 Duo Penryn 2.4 Ghz Nvidia Geforge 320M
on external USB hard disk partition. Patched with Hax3 + OpenCoreLoader4 + Beta3 fixes credits to @ASentientBot @jackluke
It boots from Apple picker, it is much faster than Beta 3.

Works: Bluetooth, Wifi, USB, ext mic, SIRI, ext Webcam
Still to fix: Ethernet, Internal Audio, Graphic acceleration

To install Mojave and Catalina you should use spoofing to a supported Mac, I have disabled that option in my customized setup, but you can use dosdude1 Mojave and Catalina Patcher to make your USB Installer to work on an unsupported Mac.
