macOS 11 Big Sur on Unsupported Macs Thread

Strange, I installed it in my MBP mid 2012 and 2012 retina and it works very well

So it seems it's my time to take a test with @Barry K. Nathan ´s micro patcher taking V 0.0.19. That's the only hint I found which could be useful to test it.

I used 0.1.0 to upgrade dp1 to dp2 but had to rerun the scripts of 0.0.19 to fix handoff, airdrop and Instant Hotspot. There was something that broke between 0.019 and 0.020 or 0.0.20 and 0.1.0

So I thought it. How did you apply? Creating new patched Stick with V 0.0.19?

I ran the unpatch.sh in 0.0.19 using the usb installer I already had with 0.1.0 after that I repatched it with micropatcher.sh, rebooted to the usb installer, ran the setvar script and then the kext script without rebooting between them. Reboot and, hopefully, all will be working

If you want a working airdrop and handoff there is no other way to fall back to PB1 and then following the above steps. I left my MBP on DP4 for this reason. My late 2011 went back to catalina for there I had the possibility to get CAT working with the result to have working airdrop.

OK. No Problem to re install DP 4...
Thanks You Very much.
Good Luck and keep share

Same.

THX --> working now especially Handoff now working in both directions.

As I promised I attach an installation guide for a working installation of DP5 or PB 2 on Mid 2012 MacBook Pro machines. For my initial situation coming from DP4 installation using Barry K. N´s micro patcher V 0.0.1 booted into USB recovery I had to reboot after applying the set-vars command and had to apply it a second one. Then the installer worked.

You will use the installation guide to your own risk although I hope to have it made right

Do you think this should work on late 2011 with upgraded WIFI Board too (Board from Mid 2011)

No idea, sorry

Tried to install Public Beta 2 on an iMac8, largely following the procedure in post #2730. BigSur BaseSystem legacy usb fix.zip built the installer, as defined in post #3409, but it did would boot.
BigSur Penryn beta3 prelinkedkernel fix enables booting (post #3258), but system hangs at the end of progress bar.
Neither of the OpenCoreAPFS loaders solves the problem. USBOpenCoreAPFSloader3b and USBOpenCoreAPFSloader4 both install on a suitable USB stick and can be booted. However, macOS never starts and the system remains at the end of the progress bar.
Has anybody managed to boot PB2 on a non-metal Mac?
I also have an iMac 13,1, which has Metal graphics but Big Sur is not officially supported by Apple. Using Barry K. Nathan's Micropatcher.sh, Big Sur installs and runs without major problems.

On MBP5,2, PB2/DP5 (version 16.0.16).
I followed the same procedure to produce the USB BS installer, and to install to a freshly erased SSD on SATA. The disk is now on USB.
Same result as iMac-Oldschool saw for booting: it will hang at the end of the progess bar, with OpenCore (from USBOpenCoreAPFSloader4) or with the Apple boot selector. I only report here for a small piece of diagnostic:

When booting with CMDS+S into single-user mode and then typing exit, the hang manifests itself as shown in the attached photos. Looping on apfs_get_firmlink_target_vnode:2009: vnode_lookupat(xxx) failed with error 2 where xxx regards private, Library, or System/Library/Caches.

On a different SSD, I have DP4 running fine. USB BS installer for that prepared with the previous BigSur BaseSystem legacy usb fix.zip. (EDIT: it is not PB1, but DP4 (build 20A5343i) on that disk - should make no difference.)

now I have time. I'll give it a try

Come to think of it, I haven't seen much of jackluke, barrykn, and 0403979 for a while on this forum...

It’s frustrating to see new members come on to this forum and expect others to get BS running on their old Macs without apparently doing the hard yards first.

Most, if not all of their problems have been solved by others in the preceding 142 pages and 3.5k posts. Therefore, like me and hundreds of others, start from page 1 and take the time to skim through every page. Take notes; copy and paste sections relevant to your model and/or year and print them out; start to experiment with patches. Keep records of what you did and what worked and what didn’t. All of this expands your mind and knowledge!!! Use it or lose it.

I’ve probably reinstalled the 5 betas, as each was released, several times over and rebooted in and out of recovery on a USB installer stick more times than I remember - but you learn and hopefully retain a bit more each time in the process, incl. repetitive lines of code in the Terminal. I now have the latest BS beta screaming along on my 2010 Mac Pro, with everything I need working and appreciate everyone else for helping me get there.

So, for those finding this forum for the first time or only intermittently, please put in the work before filling up the forum with IMO often unnecessary requests.

The bad news is, yours is one of 3550+ posts, do you think they come along this post first.

This is MR, lots of friendly people, plenty of them help others, not a bad thing if you ask me.

Even I, which has been on OS X/macOS since the very first beta, ask questions here, and helped lots of others, so to me, that's a good thing.

is there any way to run the patch on an existing installed version (Big sur Dp 5) , i already installed Big Sur DP5 (wifi , airdrop , handoff not working )

I ran the unpatch.sh in 0.0.19 using the usb installer I already had with 0.1.0 after that I repatched it with micropatcher.sh, rebooted to the usb installer, ran the setvar script and then the kext script without rebooting between them. Reboot and, hopefully, all will be working

What is that link (A virus.. Just kidding), it crashes Safari?....No kidding, I tried again and it again crashes Safari.
Safari has been buggy, can't recall it has been this bad.

So, I can't download that file in Safari, let's see if another browser will.
Another browser did the job, so, Safari can't handle the file.

That's what he said in his post, redo the patches.

I ran the patch over PB2 just to repair the handoff problem.

@jackluke @Barry K. Nathan Any improvement in fixing patches for older macs (2009-2011) in Beta5 / DP2?

Thank you!

LuisN thank you for the idea! Did just that and worked. The only snagg was that I tryed after unpatching and repatching, to run the vars.sh and then the kexts.sh but the second did not take! Told me it can't find my volume! So I rebooted and ran the kexts.sh from the terminal in the OS. Worked! Rebooted and it worked! So thank you very, very much!

Still, many thanks to @Barry K. Nathan for all his patches
