macOS 11 Big Sur on Unsupported Macs Thread

[Mike House]

This is a small guide I wrote earlier for people on the "macOS on unsupported Macs" Discord server. I followed these steps and got a working and stable install on my MacBook Pro 9,1 (mid 2012 15 inch), but without Wi-Fi support for now.

1. Download pkg from http://swcdn.apple.com/content/down...kxzj3zjshu1srsh4n74a41n4/InstallAssistant.pkg -- this is beta 1
UPDATE: Beta 2 is out, and I'm told it does work. I haven't tested for any potential bugs, but you can download it here and use this InstallAssistant.pkg in place of the Beta 1 version.

http://swcdn.apple.com/content/down...xje070in5dorjoovnmw61x03/InstallAssistant.pkg

2. Download https://forums.macrumors.com/attachments/really-simple-installer-hack-zip.926156/
3. Copy hax.dylib to home folder
4. Boot into recovery
5. Run csrutil disable in Terminal
6. Reboot and run this in Terminal while on current OS - sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool true
7. Run this in terminal launchctl setenv DYLD_INSERT_LIBRARIES $PWD/Hax.dylib
8. Open the InstallAssistant.pkg and open the Installer.app in Launchpad / applications folder
9. Wait for install to finish
Final step (only required if trying to boot on machine older than Mid 2012 (?)) - on Catalina or other OS that can access your APFS partition, delete telemetry from /System/Library/UserEventPlugins/com.apple.telemetry.plugin when complete.

Could Someone Please walk me through on how to install Big Sur on Macbook pro 2012? i got as far as running csrutil disable in Terminal and rebooted. but i have a clue as to how to run terminal in the folder where Hax.dylib is. I'm VERY new to Macbooks, and i've only had this a couple weeks. I not worried about what happens to it, because i only got it to jailbreak m iphone. Thanks

hmm..i found an terrible bug on my imac 2011:

I found a very bad bug. as soon as I upload something the network crashes. I can also upload nothing to my NAS ... you always have to unplug the network cable and plug it in so that it works again ... it just freezes can someone check the kext file? thanks i use opencore mode...installed with @Barry K. Nathan "patcher"

must i remove the com.apple.telemetry.plugin ? and how...

pic 1 : Big Sur
Pic 2 : Catalina. it that the problem?

My supported macbook air 2017 now locks up on BS-2 while youtubing etc... total lock out and needs forced restart, it never did it on BS-1

For me required internet to reinstall Beta 2
How you fixed it?

Same here on my mac mini 2012

Well the public beta is released, anyone know that the patcher or the hax thing will work on public beta?

What do the experts advise us, do we stay in Big Sur Beta 2 for developers or install the public Beta? Considering that everything works perfectly in Beta 2 and that it is an officially unsupported team.

Great work in using the "LegacyUSBInjector" with kmutil for a BootKernelExtensions.kc (or KernelCollections), with the MacBook6,1 since it has an Nvidia GeForce Tesla, could you try to add framebuffer video (as you done for IntelHD3000) to your patcher ?

I tried, but I ran into the same problems you had with NDRVShim, and my attempts to work around that have also failed (so far). (I intend to come back to it at some point, however.)

Thanks for the discussion between you and @testheit. There's a lot of information for me to go through and for me to experiment with. I might not get around to it until late in the weekend or early next week.

Without rebuild any kextcache or kmutil at next reboot Sound internal speakers and Mic should work.

For what it's worth, my experience has been that it's a little difficult to predict which kexts will work without doing kextcache/kmutil.

It's such a shame installing beta 2 takes so much effort, the initial release wasn't too hard after reading the posts here, beta 2 is more a headache for me, I do not have an external boot option except for a Catalina external recovery, I tried to invoke the Install from a terminal in recovery, I could not (weird) see the Installer on my external, it's a data backup HDD which also holds the Cat recovery, I then navigated to an alias on the SSD, permission denied, WTF.

Most people don't even realise you can open *Applications even in recovery with terminal, except this time I could not see my GTech Backup HDD thus inaccessible Installer.

I do this by typing the path to the binary, so for instance:

/Volumes/SSD\ -\ DATA/Applications/Appname.app/Contents/MacOS/Appname

It should open, there could be issues though due to supporting inaccessible support files.

 

[Barry K. Nathan]

you can try sudo /Applications/Install\ macOS\ Big\ Sur\ Beta.app/Contents/Resources/createinstallmedia --volume, then download this https://github.com/barrykn/big-sur-micropatcher after your created the Big Sur usb drag the micro patcher.sh in the terminal then drag your Big Sur usb into the terminal and hit enter

With my patcher, dragging micropatcher.sh into Terminal then pressing Enter should be sufficient -- it'll find the Big Sur USB automatically based on the name that createinstallmedia gave it.

Patching and OS support is yet to be determined with Big Sur, but keep an eye on this thread as work is being done to get these Macs up to date in terms of WiFi technology. Adapter + Card is due towards the end of this month and grabbing 2 of them myself.

802.11ac and BT 4.2 are here for unibody MBPs and A1342 MB!

I am pleased to announce that 5 years after my post found here (where I threw in the towel early): https://forums.macrumors.com/threads/macbook-pro-802-11ac-upgrade.1521466/page-4#post-18438927 , native 802.11ac WiFi and Bluetooth 4.2 are working on classic unibody MBPs! :cool::D All of this...

Thanks. I am keeping my eye on this one!

Got everything up and running now using the HAX method detailed a little earlier, SIP disabled and script run to enable WiFi. The OS is smoother than Catalina on my MBP Mid 2012, go figure!

Anyway, the only issue I appear to be having is that I cannot change preferences in Messages for some reason. Has anyone come across this, it's greyed out?

Never mind, it appears that you have to send a message to enable Preferences for some strange reason

Hi Mike,

What has helped me in my MBP mid 2012 (not retina) is to follow this method:
Big Sur on Unsupported Macs

After installing the Beta you do not have WiFI in addition to other things ..., that has been solved with the help of @jackluke and its magnificent:

"BigSur IvyBridge prelinkedkernel Sound AirDrop fix beta1.command.zip" (you can search it in this same forum)

Everything works perfectly for me, in fact, much better than in Catalina

I hope I've helped

😊

I don't have a 2011 iMac myself, but you've provided enough information that I can compare with how things work on other Macs and see if I need to make any changes to my patcher. (It's possible I won't be able to do that until next week however.)

Don't bother removing com.apple.telemetry.plugin. If you need to remove it, you'll know because Big Sur won't even boot.

The public beta came out today for iOS, iPadOS, etc., but not yet for macOS, as far as I can tell. It doesn't seem to be in the public beta catalogs on swscan.apple.com, and when I log into my beta program account, the beta.apple.com site still says "Coming Soon".

And when it comes out, what do you advise us to do, continue in Beta 2 or re-install the public Beta?

Thank you very much for the help.

Looks like you guys already got this sorted, but it was a simple fix for the "Hax.dylib" thing if anybody with a non-APFS Mac would like to test this. Please report your results if anyone uses it!

I’m using Hax3 to install BS Beta 2 on a fresh partition, but the usual loading bar changed to this Updating… screen and got stuck.
Is there a Hax 2 or 4 to test? Or should I return to Hax 1?

That screen is OK. (I don't know why it appears sometimes but not other times. I had a theory, but if you're seeing it on an installation to a fresh partition then that definitively disproves my theory. By the way, I've seen it with beta 1 but haven't yet seen it with beta 2.) It may look stuck for an hour or more, but just let it sit there and give it time! That progress bar moves at geological speed and makes it look like it's going to take 12 hours or something, but I assure it won't really be that slow.

If things turn out the way I expect, then wait a couple days after beta 3 comes out in case the public beta comes soon after. (If things don't turn out as I expect, then I'll have to actually take a look at the public beta in order to have an informed opinion.)

Hey @Barry K. Nathan, I did try install Beta 2 from scratch with your patcher, but when I start the installer to choice the partition, get the error "Operation cannot be completed (BIErrorDomain error 3.)"

I don't know if you try in Beta 2 from scratch, but don't works

Can someone please walk me through the Opencore 0.6.0 spoofing for a 2011 MBP please? Thanks

Actually.. I haven't got that far yet. still trying to figure out how to run the terminal to be able to install it.

You need to restart your Mac from the patched USB drive (restart the Mac, hold down Option/Alt, choose "Install macOS Big Sur Beta"). After it starts up, you need to go to the Utilities menu (I'm not sure what it's called in Brazilian Portuguese, sorry), open Terminal, run the command /Volumes/Image\ Volume/set-vars.sh (you can probably type /Vo<tab>/Im<tab>/se<tab>, where <tab> is the Tab key), then quit Terminal and run the Installer.

I plan to simplify this in a future version of the patcher, but the patcher needs other improvements first, and even with a future simplified patcher, you will still need to start your Mac from the patched USB drive.

I have had that screen a few times then my screen flashes then it goes back to that screen but I found a way around that and the pop up saying you need internet access to install I used parrotgeek's method to create my Big Sur usb then I dragged the micropacher into the terminal then dragged my Big Sur usb into the terminal I got Beta 2 installed that way but no wifi

For WiFi, look at step 9 in my patcher's README. Basically, boot off the patched installer USB again, open Terminal, run /Volumes/Image\ Volume/patch-kexts.sh /Volumes/Name\ of\ Big\ Sur\ System\ Volume (replace "Name\ of\ Big\ Sur\ System\ Volume" with your actual Big Sur system volume). If you're on a 2011 Mac, add --2011 (like /Volumes/Image\ Volume/patch-kexts.sh --2011 /Volumes/Name\ of\ Big\ Sur\ System\ Volume -- the "--2011" must go between the two "/Volumes/...") to get working sound (and on HD 3000 GPUs, a working framebuffer/sleep/brightness) as well as WiFi.

SIP is disabled on my mac since what....forever.

$ csrutil status
System Integrity Protection status: disabled.

Even if csrutil status shows disabled, run csrutil disable and reboot. It’s worked for me hundreds of times.

Am I reading this right that the 2011 models with the intel 3000 video are working WITH video acceleration on Big Sur? I must have missed that group of posts?

I tried that several times always says can't find /Library/Extensions on the volume and I have Big Sur install on a OWC Mercury Electra on a Seagate USB adapter so macOS doesn't not recognize it as a SSD as it is the only one I have and I have to use the OpenCoreAPFSloader3 to be able to boot into Big Sur and my volume is sealed as Starts with the Phase 1 3 min then reboot to phase 2 Black Screen Apple Logo 29min install then reboots to a black screen with progress bar then screen flickers comes back with another black screen and progress bar but goes faster then the screen goes grey then into the setup. your Mac screen on my iMac 13,1

@Barry K. Nathan I did all this, but nothing, I followed the "patcher's" README from your Github to make sure that I've done all right, but the error keep going

My actual Big Sur volume is named "MacOS Big Sur Beta" . What should I write in step 9 of your patch instructions??
