macOS 11 Big Sur on Unsupported Macs Thread

[Larsvonhier]

would i be able to install this on a late 2008 15” macbook pro and how well does this run on 4GB of ram without a ssd and does anyone have a guide for this or can make one

Yes, you can ;-) (install it on MBP 4,1)
But without SSD I´d not recommend it other that for curiosity, even booting from HDD is really taking ages, also starting apps etc. Once running, it´s ok then. 4GB is also ok (with SSD!), but you can equip your machine with 4GB+2GB memory sticks (types 5300 and 6400 both work when mixed - but only 2x 6400 types does not).

On my Macbook Pro early 2011 i have 6GB of RAM i wont need a ssd as i have a pretty fast 10000RPM hard drive is that enough ram for several apps as i open a lot of apps also when you first boot the system how much ram does the os use if you could send me a screenshot that would be nice also i am currently using mavericks for its speed and optimization is mac os big sur the same speed and optimization

 

[Larsvonhier]

Folks, please be reminded that even on supported machines, Big Sur is in a very very early beta phase.
To ask questions about "how optimized / performant" it is on unsupported machines without full GPU acceleration does not really make any sense (yet).

[Dave1423]

i must ask did they fix the acceleration for my macbook pro 2011 i did see the video on it not having it is this fixed for my model

and can i do this on high sierra

For prelinkedkernels, possibly. For KCs, no. With KCs, kextcache can't do anything on its own and tries to invoke kmutil to do something equivalent -- but we need to invoke kmutil in our own special way for LegacyUSBInjector to work. So kextcache won't be able to do any good and might do some harm.

This may seem like an argument for patching IOUSBHostFamily instead of using LegacyUSBInjector, until you think about it more and realize that any situation where Big Sur is going to automatically rebuild the boot and system KCs is also a situation where some installer or other is going to remove any kexts we add to /System/Library/Extensions anyway, or at least overwrite IOUSBHostFamily. (I just checked IOUSBHostFamily on my High Sierra system and in fact it was updated by the security update a few days ago.)

(And if we put LegacyUSBInjector in /Library/Extensions, it'll go into the auxillary KC, so I think it'll end up loading too late, if it loads at all. Maybe I'll test this at some point.)

I don't see how this situation differs that much from Catalina. Normally it is considered good practice to reapply the patches after any Security Updates to make sure patches aren't regressed. So we would just be checking IOUSBHostFamily for the presence of the Info.plist patches and re-applying them if regressed.

Late 2008 MacBook Pro is 5,1 but should probably be identical in regards to installing Big Sur on the 4,1 (early 2008)?!

What would be the preferred way to manually install Big Sur B2 on the MacBookPro4,1? (Never have used OpenCore or 'prelinkedkernal fix' myself so far, if those are what’s needed).

Thanks it works , i succeed log in
But no sound ( HDMI sound doesn’t appear)
no Wifi
Lot of Lag and much noise of cooler

any idea ?
thank you very much for your Help !

If you have a machine with IntelHD3000 GPU use this: https://github.com/barrykn/big-sur-micropatcher

but you need to make a new USB BigSur Installer from where through its recovery terminal you can install the patched kext Sound, Wifi and mainly the IntelHD3000 kext for framebuffer video .

Thanks for your help but have i to make it at the beginning with create an other install stick ?
Could i use this patch on my Big sur "parrot geek " installation or new installation with new boot stick and erasing my "parrot geek installation"
Is it a simple way to do it from my Big sur installation or Catalina, and no erasing ?

 

[HackMini]

Hey guys, sorry to barge,
This is HackMini's friend, Mikey. I have a 2010 MBP that has a major issue. The EFI partition is empty, and can't get it to boot off of the startup disk! I tried everything! (Resetting SMB, reinstalling macOS, transferring EFI files from a different drive, etc.). I have no clue how this happened! Please help if you can! Thank you all and thank you to HackMini for letting me post this on his account.

This happened while I was trying to spoof with Clover to install macOS Big Sur. Sorry for not mentioning this.

Thanks but could you explain me How to do this, i don’t understand .
Have i to use this patch from my existing Big Sur Os or do it like an other installation and make it from Catlaina like Parrot Geek one ?
Thanks .

 

[CsYager]

I can't understand the computer jargon going on here, so I'ma wait until further progress is made to test out this one.

You need to make through new stock createinstallmedia for USB BigSur then apply the micropatcher script to it, that will add some additional recovery scripts to install kext (mainly the IntelHD3000 kext) on a sealed snapshot system, you don't need to reinstall BigSur just boot from USB BigSur installer terminal and apply the micropatcher set vars and patch kext sh .

You need Catalina to make this because the packages are downloaded.

a very early Alpha version of Aerial screensaver for macOS Big Sur just be warned it maybe buggy but this is my fav screensaver.

okay so I got it up and running does anyone know how to get full graphics acceleration for this

I'm hoping the Wifi solution I've been using since the days of my unsupported Mac Pro 1,1 days and thru 5,1(flashed) will hold true. The Asus AC68 PCI-e adapter card. I'm still having trouble creating an installer that will get into setup. I really want to find out if the my steadfast wifi will stay strong. Once, I get a nibble on Big Sur I'll share any wifi failure or success.

Works out of the box! Installed it after BS b2 was installed.

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 just released v0.0.14 of my patcher. Yes, it went up a few versions; I wanted to leave open the option of releasing a v0.0.12 or v0.0.13 that has a subset of the v0.0.14 changes, in case that might be necessary for testing or diagnostic purposes. (I now don't think that will be necessary, but I wanted to leave the possibility available.)

Quoting from the release notes:

The big user-facing changes are:

• The README now discusses the compatibility of different Mac models in much more detail.
• patch-kexts.sh now has a --all option that installs all of the modifications that it can do. This is useful because...
• patch-kexts.sh, with the --all option, now installs LegacyUSBInjector, which enables USB on older Mac models such as the white polycarbonate (Late 2009/Mid 2010) MacBooks. For now, you still have to do the installation (and run patch-kexts.sh) on a 2011 or newer Mac (or maybe a 2009 or later Mac Pro), then transfer the installation over to the older MacBook (either by moving over an external USB HDD/SSD or by transplanting the HDD/SSD), but a future patcher release might patch LegacyUSBInjector into the installer USB.
• In addition, patch.kexts.sh --all also installs nvenet, because that's needed for Ethernet on many Macs that require LegacyUSBInjector.
• There is a new shell script, zap-snapshots.sh, which will delete all but the most recent snapshot from the APFS system volume. (I only tested it while booted from the patched installer USB, so it probably won't work when run on a live Big Sur installation, but I can fix that in a future patcher release.)

Under the hood: To enable LegacyUSBInjector, kext collections are now built a different way, based on a suggestion by testheit on the MacRumors Forums. I believe the new method should also be more reliable in the face of kmutil bugs. Also, all kexts which are taken from High Sierra have been updated to the versions from Security Update 2020-004.

I might do another release tonight or tomorrow morning if I'm able to do any meaningful improvements between now and then, but there's a chance that I won't be able to, which is why I wanted to make sure I finished this release before beta 3 comes out.

Edit: The release notes originally omitted some of the changes, so I've updated them both on GitHub and in the above quote.

Will the ParrotGeek or barrykn patcher work with a haswell based Hackintosh?

 

[Barry K. Nathan]

Only BootKernelExtensions.kc showed parrotgeek using grep. As I mentioned before, the resulting BootKernelExtensions.kc can boot into the Big Sur graphical interface from a usb external drive (proving that it has legacy usb support for the boot) but then produces the Bluetooth keyboard dialog indicating that the usb keyboard can't be found. This seems to indicate that the boot process switches over from BootKernelExtensions.kc to SystemKernelExtensions.kc which is missing the LegacyUSBInjector.kext

This is definitely something I need to investigate further (and maybe I should've done that before releasing my v0.0.14 patcher update in retrospect). I'll look into this later today. (Things happen to work on my MacBook6,1, but the more I think about it, the weirder it seems to me for a kext to be in the boot collection but not the system collection.)

Edit: Now that I've looked into it, it appears that none of the kexts that are in BootKernelExtensions.kc are also included in SystemKernelExtensions.kc. I think they get used together, rather than switching from one to the other.

Does the micro patcher work on my MacBook Pro 2008

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.

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.

?macOS 11 is just an Apple flower name, isn't it?

Always 10.16 in the BigSur system.
