Go to the Apple Menu and choose About This Mac. What does it say for "Graphics"? (And if it does not mention a brand name like Intel or AMD, it would also be helpful to know what About This Mac says for "Graphics" on a previous version of macOS.)

There were a few different hardware configurations of the 2011 Mac Minis, so this information will help me figure out what's happening.

Thank you to help me.

Would you mind trying again to post the screenshot for the video card under Catalina? I see the Wi-Fi information for both Catalina and Big Sur but I only see video card information for Big Sur, not Catalina.

Hello ,
It's ok for transparency and login.
But Wifi , Sound with HDMI and Airdrop don't work . (I did make a new usb stick with the micropatcher )
It seems like new kekts are in place but
- HDMI doesn't appear in sound
-Wifi can't be active
- Aidrop doesn't work.

Have you an idea ?
Thanks a lot for your help.

For Wifi and AirDrop as you did for Catalina use this (both the kext): Macmini5,1 AirDrop Catalina.zip

But to install it on BigSur is a bit different, boot from USB BigSur Installer open terminal recovery type:
csrutil disable
csrutil authenticated-root disable

reboot to normal BigSur booting, from there follow these steps:

So perhaps 10.16 on intel and 11.0 on ARM as a distinction? Would be a new scheme but who knows but Apple...

Thanks. I see that your Mac Mini does in fact have Intel HD 3000 graphics (good) but that the kext isn't loading under Big Sur. Assuming you properly followed step 9 in the micropatcher README, I'm not sure what could be going wrong. (If you're not sure if you did step 9 properly, or if you didn't do it at all, then do it again. Just step 9, none of the other steps. Make sure not to forget the --2011 command line option -- if you forget that, WiFi might work but sound will not work. Or, if you've already installed jackluke's AirDrop fix, then use the --2011-no-wifi command line option to avoid overwriting that but still get working sound.)

So, try step 9 again and if that doesn't fix it, I'll try to figure out further troubleshooting steps.

It sounds to me like it's going to be 11.0 on both Intel and ARM at some point before Big Sur is actually released.

I now got BS Beta 2 on my 2009 MBP 15“ 2.66GHz running (thanks to all devs and helpers here), or better creeping. Okay, it boots up etc. but as expected some things don’t work. I injected the High Sierra AppleHDA.kext but it doesn’t get loaded. So Sound doesn‘t work onboard (but an external USB sound card works). Also the Nvidia Tesla Kexts which I inserted correctly are shown but not loaded. The Icons/control center in the menu bar on the top causes the UI to crash and pushes me back to the login screen. But everything else works ok. Hope that some devs will fix the Metal Requirement to work on older GPUs and the other errors caused by the unsupported machine. Is anyone working on a Metal fix or something else concerning this? Just to tell: because of the non-loaded kexts also the background light control don’t work. Sorry that this post could maybe annoy somebody but I read the first 63 pages and my head just spins? so any further successes?
With many thanks in advance,
theANY

edit: FYI I do boot BS without OpenCore.

I have the MID 2009 MBP 13", How install this??

I just released v0.0.14 of my patcher.

You made many useful improvements to your patcher, just some advises:

- for any machine with a Penryn Core2Duo (to skip kp before loginUI) you should put in BigSur kernelcache (BKE or prelinkedkernel) the Syncretic telemetrap.kext or simply remove the "com.apple.telemetry.plugin" making a new snapshot without it

- any iMac (or Mac) with legacy USB (or non-APFS) equipped with a Penryn Core2Duo can boot BigSur desktop (thanks to ASentientBot and to parrotgeek1 for LegacyUSBInjector), while instead probably the i3 cpu iMac (as the Arrandale i5 or i7) can't boot BigSur (I guess a similar issue as AppleACPICPU early booting kp)

- as you know after a fresh BigSur beta 2 install (or later) for non-Metal Nvidia Tesla GPU (also IntelHD3000 and maybe ATI too) after the welcome screen there is the Finder crash, so you should consider a way to preset the reduce transparency (I guess "defaults write" won't work from recovery environment, so you could use my patched plist and replace even if it needs first the applesetupdone)

Yes, the --all option in patch-kexts.sh also disables (renames) com.apple.telemetry.plugin, I just forgot to mention that it does so.

I'll update the README regarding i3 iMacs in a future patcher release.

If you do a fresh install of Big Sur (maybe this works on some upgrades too, I'll have to check later), you can enable Reduce Transparency in the Setup Assistant. I'll see if later in the week I can create instructions on how to do this.

 

[MacHacJac]

Wow! Thanks Barry! I'll try this out on my machine with Intel HD 3000! Hope it doesn't crash!

 

[Dave1423]

yeah that link when I try to download it it just ends up cancelling itself due to "The network connection being lost" but everything else downloads anyone else having this problem is there any other links or a google drive link here the one already posted comes up with a "404" error

 

[Dave1423]

how do I get it to boot on my 2008 MacBook Pro it is showing a "STOP" symbol when I try to boot

 

[webg3]

anyone got a MacBook Air 2012 13 inch fully working?

I have, MacBook Air 2012 11 ". You need to read a few pages back, and follow some of the methods mentioned.

I continue using 10.16.0 DB2 on my MBP5,2 from time to time. BS was installed using Hax3.app and prelinkedkernel fix4.command. I used migration assistant to successfully pull all my user data and applications from Catalina to BS.
BS is on an SSD on USB (needs to be on SATA during installation only).

This time, as Photos 6.0 keeps crashing at start (initial library transformation went well), I thought I try Photos 5.0 from Catalina. From Catalina, copied it into /Applications of BS as Photos5.0.app (Photos 6.0 resides in /System/Applications).

Afterwards BS couldn't boot - the activity LED of the USB disk interface stopped blinking during boot, as if legacy USB were gone. So this BS installation looks vulnerable, but was easy to fix: re-applied prelinkedkernel fix4 from Catalina, and booted OK again.
Ethernet and internal audio still working.

Photos 5.0 can't run on BS though. So the main outcome of this small exercise was that my BS installation got hurt by putting something into /Applications this way.

Another small observation: cursor movement is patchy in general, esp. on the desktop. If there is some other window in the foreground, like system settings, movement is almost normal, even on the desktop part of the screen. Then even without acceleration, one can do some useful tests with BS.

Looking forward to the next beta. I plan to install it over my present BS using again Hax3 and prelinkedkernel fix4 (if the new beta will have a full installer).

FAQ:

Q: Why did Apple drop support for my perfectly capable Mac?
A: Only Apple can give a definite answer to this. However there is evidence that it is based upon the CPUs being used in the now-unsupported Macs, which was the case last year with the Mac Pro 4,1/5,1. Intel decided to stop releasing firmware security fixes for Ivy Bridge and previous-generation CPUs. While they are technically compatible and supported in Big Sur, Apple has decided it is not worth the risk to continue supporting CPUs that have permanently unpatched security holes, putting users at risk.

While this is also not confirmed, another possibility could be that some of the excluded Macs feature Wifi chips that are no longer deemed fit for the next major release. This decision could be based on the previously mentioned security issues as well. The presence of graphics drivers for some of these newly unsupported Macs in Big Sur Beta 1 suggests this.

Q: Will my unsupported Mac get macOS 11.0 Big Sur?
A: If your Mac had official support in macOS Catalina, they will likely be able to be patched to run Big Sur with minimal issues. As of writing, only WiFi appears to be broken.
If your Mac was unsupported before the release of macOS Catalina, support remains to be seen as graphics acceleration may not be feasible at this time. While Catalina still supported OpenGL (former macOS graphical API) and even used it as a fallback software render mechanism, Big Sur officially drops support and shifts to Apple's Metal API entirely.

Q: When will my unsupported Mac receive macOS 11.0 Big Sur? / ETA when?
A: This is a community driven effort to try and restore support for various unsupported Macs. Community members are working as hard as they can, often in their spare time, to try and add back stable support for these Macs. Based upon changes in macOS Big Sur, it may be possible some Macs that were previously patchable in Mojave, Catalina, and other previous releases of macOS may not be patchable under Big Sur. Please do not harass the patch developers to go faster, release the patcher, etc. Please do not clog up the thread with useless posts asking if your specific Mac will be patchable. Big Sur was only just released in its initial beta form and a lot is still subject to change before the final release. Rest assured, the dedicated community of developers working on these patches are doing everything that they can to re-add support for as many Macs as possible.

Q: Where/how can I download macOS 11.0 Big Sur?
A: For legal purposes, the only official way to obtain a copy of macOS Big Sur is to be a registered Apple Developer and pay a yearly $99 fee to become eligible for downloading beta software. According to Apple, a public beta which does not require a registered Developer account will be released at some point in July and will be free to sign up for. Please remember it is highly suggested that you do not install beta software on your main devices, overwriting any stable releases. Beta software can cause irreparable hardware damage or irrecoverable data loss and should be used at one's own risk.

Apple and all patch developers are not responsible for any potential damage or data loss caused by using pre-release software or unofficial support patches. Please use at your own risk.

Can I install macOS 11.0 Big Sur on my Macbook pro8,2 early 2011, I have Catalina 10.15.6 installed already? Thanks..

I have the MID 2009 MBP 13", How install this??

I will write a useful Tutorial soon. For now:


First I downloaded and installed the InstallAssistent.pkg from beta2 so I have the macOS Beta installer. After that I created a new APFS partition (NOT a new container in the installed Catalina). I rebooted into Recovery and disabled SIP with csrutil disable.

Then I used the Hax3.app to start the installer in Catalina and let it install BS on an APFS-formatted Partition even though the installer detects a non-APFS Mac, into the new created APFS partition. (I patched my ROM with a very special patcher from dosdude1 so I can boot APFS natively.)

Afterwards I let it install until I get into a boot loop. When it loops I boot into Catalina and execute the prelinked kernel fix 4 and patched "/Volumes/Preboot/UUID-BigSurData/Library/SystemConfiguration/com.apple.Boot.plist" and "/Volumes/Preboot/UUID-BigSurData/Library/Preferences/SystemConfiguration/com.apple.Boot.plist".

Then I copied the same com.apple.Boot.plist to "/Volumes/Preboot/UUID-BigSurData/System/Library/CoreServices/". After this I deleted the Telemetry plugin "/Volumes/BigSur/System/Library/UserEventplugins/com.apple.telemetry.plugin" because it causes the Mac to crash.

When all of this is done you can boot into Big Sur without OpenCore! Only things not working for me are graphics acceleration and Sound even though I replaced the original AppleHDA.kext with the High Sierra one. I also inserted the Nvidia Tesla kexts but they doesn't get loaded. Because of that the system is a bit slowed down and the menu bar icons will cause the UI to crash and push you back into the logon screen. Also the Photos app crashes every time it gets started. The way I inserted kexts into Big Sur (from inside Big Sur):

I looked via mount for the partition with the syntax diskXsYsZ (for me it was disk1s2s1). Leave away the sZ and mount the partition with that syntax name into a new folder, like that: sudo mount -o nobrowse -t apfs /dev/diskXsY "Mount-Folder" (use for mount-folder the respective path). Then I opened the mounted partition with open "Mount-Folder". I removed "System/Library/UserEventPlugins/com.apple.telemetry.plugin" and replaced "System/Library/Extensions/AppleHDA.kext" with the High Sierra one. I think I need the El Capitan one, I'll try out later. After I did these actions I executed the following commands:

sudo chown -R 0:0 ~/Snapshot/System/Library/Extensions/
sudo chmod -R 755 ~/Snapshot/System/Library/Extensions/
sudo bless --folder ~/Snapshot/System/Library/CoreServices/ --bootefi --create-snapshot
tmutil localsnapshot

Is there a way to install it in the Mac Pro 3,1?

 

[astuermer]

I own a Macbook Air 11' Mid 2012 - seems the WiFi card won't work if I install Big Sur.
Does anyone know, what WiFi cards are compatible with it?

Thanks!

 

[vvapple]

It really bugs me that my perfectly fine iMac 2013 27" doesn't get the BigSur Update. I don't see the technical reason for that.

Small question:

What happens once I patched my iMac and there is another x.1 update coming, could I potentially just run it as normal then or would it require different steps as well?

 

[jackluke]

Looking forward to the next beta. I plan to install it over my present BS using again Hax3 and prelinkedkernel fix4 (if the new beta will have a full installer).

Maybe with BigSur beta 3 they (AAPL) could introduce the OTA updates, but you can anyway download a BigSur beta full installer using CatalinaOTAswufix from any Catalina release, the Catalina software update prefpane will show the full BigSur beta installer, that is initially downloaded as an OTA in /Library/Updates/ but after automatically repackaged by apple postscripts on Catalina /System/Applications/ path, so you should result in a full "Install macOS Big Sur beta.app" (about 10 gb size).

CatalinaOTAswufix doesn't work directly on BigSur because seems they changed the update process, probably they use now the APFS Update volume.
