macOS 11 Big Sur on Unsupported Macs Thread

[air.man]

good ol days at apple.....those who love Mac OS or apple products should read the apple credo.....this is what I received as a new employee 20 years ago and its the principle of why apple was started and why we are here and I think its important because it applies to the hard work of the people developing these patchers....its important because its more then extending life of technology....its about friends, and family and who you are.....deep stuff read and enjoy

I fully understand you. I worked for HP for 30 years, starting end of 70'. We had the chance to work in an ideal environment that developed the technology and promoted the individuals, everywhere they sit in. I spent wonderful years working there.
Welcome back!

WakeUp! It's Beta release, first beta of 11.4. =)
And after installation process was done - MacOS started without issues and works fine.

Again I asked if you tried rebooting several times to confirm there are no issues? There is a whole thread here

Mac OS 11.3 has broken support for older Mac Pros

macOS Big Sur 11.3 Beta 3 has broken Mac Pro's early-2009 to mid-2012 ability to boot reliably into macOS. It's still possible to boot 11.3/11.4, but the process requires multiple restarts and a connection has been made between PCIe devices, especially storage related devices and USB controller...

About BS 11,3 and 11,4 not properly/consistently booting on cMP and claiming that everything is OK is misleading.

Question on OCLP, with my i5 Mid 2012 Air, the About This Mac i5 clock speed was 1.8, after a OCLP install it now reports 2.3. Anyone know why this is reported wrong?

Successful fresh install of 11.3 using OCLP v0.1.1

 

[maverick28]

My main concern is after installing Big Sur will I be able to reboot seamlessly to other partitions and back?

Ok. Specially for you. I shutdown my Mac and powerUp again and system boot without issues.
Any question?

Well, it is not for me but for all of the others for whom it is not working. I am glad it is working for you though.

Hi guys im actually new here and ive been using a MacBook Air 11 inch Mid 2011. Ive install Catalina and Majove patcher in the past. But recently I've switched from Catalina patcher to Majove patcher since its much smoother. And oddly enough I received a notification saying that software update available and its the Big Sur update. Does it actually works or its just a bug? Im actually downloading the update rn.

do not download. it will make your machine crash totally. Since you are using patched mojave and catalina in unsupported MacBook air mid 2011. Big sur too requires its own patch and does not run too good as it has acceleration issue in graphics. check my signature. Stick to catalina right now.

go to system preference and under software updates untick under advanced "install mac updates & system update". you will not get anymore update prompts.

If using OCLP, you can just hold Option when booting like before. OpenCore intercepts Startup Disk, however, so you won't be able to use that.

All the invites on the site are the same one as you found, so where did you find the expired one? I can go and fix it

The link on the announcement of the coming Paradise was dead, @khronokernel fixed it yesterday I would assume.

I have managed to install OSv11.2.3 via Opencore legacy patcher 0.1.1 from Github several days ago. Now I have found an update natively in Software Update in System Preferences to OS v11.3. It is now obvious to me that it is not as simple to update as it is via a native Mac OS11 System. Long story short: I corrupted my Opencore OS 11.2.3 and I had to rebuild it after attempting to update through the native installer. Does someone have simple instructions I can follow? I am not a developer; just a user. Any help would be appreciated. It is wonderful what Github/dortania has given us with this patcher.

Finished the 2.7 2011 with the converter 2009 screen today. Everything worked fine until I made the mistake to start up the original HS I kept on my 1 Tb disk. This corrupted my boot signature for the BS I had on my SSD. Strangely enough I manage to boot to BS from the Option selection, but not from the efi boot. if I set the SSD as default boot I get an invalide signature failure, So I decided to re-install Big sur. Is there an other workaround for this, or should I just ditch the original High Sierra and never start it again?

I don't use OpenCore Legacy Patcher, but OpenCore 0.6.8
both can work with the EFI folder on the internal partition
the secret is there, in this internal EFI partition
if you copy the EFI folder containing the following subfolders: BOOT, OC will boot perfectly.

EFI >
EFI >
APPLE
BOOT
OC

this structure can receive OTA updates, needing only the correct OpenCore or OpenCore Legacy Patcher config.plist and files of your system

Who is exactly we? The last guy insisting on using the 1st plural when speaking about himself got his head cut of more than 200 years, ago. Not a good idea to start this nuisance, again.

Apple Home, Apple Maps, Apple photos and others rely on the metal techology and will probably never work properly unless you buy a metal GPU based Mac. Patching back graphics acceleration for your old card means is bringing back mostly OpenGL - did I mention this before? The patches are not a metal emulator for old graphics cards. Nobody will do this without proper engineering docs - whohoo - these are Apple internal. These apps had their problems before on Mojave and Cataline, do not expect to get newer version with less metal technology included.

What is coming next? Final Cut Pro X does not work properly on your iMac?

Hi Everyone,
Just trying to get pointed in the right direction troubleshooting an issue.

I have a Late 2009 iMac 27" originally i5 and 4850. Recently upgraded to i7 870 and a K2100m. Current installed OS is High Sierra, goal is Big Sur.

I read this guide through several times, taken notes and tried to do everything correctly but am unable to boot to a GUI and am at a loss. Any help would be appreciated.

What I did:

• Created OpenCore/BigSur EFI thumb drive in High Sierra.
• Installed new CPU and GPU, everything went well. GPU is one I got on eBay pre-flashed an K2100m.
• Can boot to EFI menu.
• At this point it doesn't matter if I try to boot existing OS, or install Big Sur. In both cases it will get to the point it should load the GUI (I believe) and then halts.

Attempted troubleshooting:

• I have tried doing several different OpenCore builds, tried different settings, forcing metal, minimal and moderate SMBIOS, Disabled SIP and Secureboot. Manually specified the model etc...
• Mounted EFI, looked at logs, have some kernel panics and the OpenCore logs, unsure what I'm looking for TBH.

Logs Attached

When you ran the APFS ROM Patcher on the Mini3,1, how long did it take?

Just a guess. What is your firmware/ boot rom version?

Read this article on which version works for Big Sur and what to do if your version in not suitable.
