macOS 11 Big Sur on Unsupported Macs Thread

[Alex-Microsmeta]

Wow! It works!!! USB mouse and keyboard stable and fast on Mac mini 2010 without OpenCore. Finally I do not have to switch Apple (horrible) magic mouse from iMac 2013 or start with CMD + S
Thank you very much my genial friend @jackluke !

Congratulations! Very elegant, simple and working USB Installer user interface 👍👍 Also the system on SSD is surprising fast and responsive without graphic acceleration, now installing Chrome and other 3th party softwares.

Obviously BIG thanks to all you geniuses here that make this possible! @dosdude1 @parrotgeek1 @jackluke @Barry K. Nathan @ASentientBot @hvds @Syncretic @testheit and all other ethical hackers that support dummies like me, instead of the missing Apple support

[edit Found the button on right menu 😂] HI @jackluke How to install Hax3 fix? I'm making a full installation on BigSur EXT, I have tried to open hax.sh or install MacOS from USB Menu, but no output given and is impossible to update BS Beta 10

HI @jackluke How to install Hax3 fix? I'm making a full installation on BigSur EXT, I ave tried to open hax.sh and install MacOS from usb MENU, but no output given and is impossible to update BS Beta 10

Click from Utilities Hax3 quick fix or from main menu Hax3 Installer fix (upper right icon to show the output), then "Install or upgrade macOS" will work from menu.

I used this method because in this way basesystem fix should work also when apple drops the Beta naming or when use again Beta naming for 11.0.2 and next beta releases.

Solved, sorry for asking instead of simply reading your notes

I'm following this post since day one.

But my actual machine it's my working machine, and I went very busy all this lockdown in my country in home.... AND my connection it's 2mb... so I haven't yet tested all this procedure...

But reading through all the threats I haven't seen one doing it in Mac mini 2011 5,2. I have that (selling, but I would like to try to offer with it) and this MBP 9,2 which I know the right procedure and success for severals.

For that Mac mini 2011, the procedure will be like MPB or legacy?

For that machine you don't need Legacy USB fixes, you can use micropatcher or if you use my basesystem fix simply after BigSur installation apply "BigSurFixes snapshot booting" (or "BigSurFixes disabled snapshot" if you need "sudo mount -uw /") and "BigSurFixes graphics framebuffer".

Success patching Mac mini 2010 (Macmini4,1) with the new @jackluke patcher.
Also if it is one of the most problematic macs, all works fine and fast: Apple booting without OpenCore, Bluetooth, Wifi, USB mouse and keyboard, internal audio, external USB mic and Webcam (but no Siri) , widgets. Only graphic acceleration is missing.

If this is your working machine, do not make Big Sur your main boot.

Hi @ASentientBot ! On Mac mini 2010 I have noticed that on 11.0.1, with your framebuffer patched with latest @jackluke installer, the dock windows are transparents (only on black theme). Also when selecting the frame while capturing the screenshot with cmd+shift+4 it is transparent! Maybe this could be useful to find a trick to make trasparent also the menu bar and dock.

What is this devilry you speak about? Simple and working USB installer with an interface? Has someone come up with an easier usb installer such as dosdudes? I bow down to all those developer gods and huge respect to them but like someone mentioned on here, Im no terminal gandalf either when is comes to coding. Could you point me in the direction of said usb installer if one truly hails? Many thanks.

Simply don't use it, write your own patcher and don't bore us offending the genial developers here, kindly giving support to us.

For today, if apple release a full "BigSur Install app" almost surely they will drop the Beta naming, then since maybe I am not yet ready to update it , to allowing Install or upgrade to a "non Beta BigSur", after used my BaseSystem fix and launched the ASentientBot Hax3 installer fix, simply open an installer terminal and type this: /Install*/C*/M*/InstallAssistant

edit:
Updated with some addons (added a custom icon for ASentientBot great Hax3 fix) my BaseSystem fix (just repeat same previous fix and fix2 remaking the USB BigSur Installer), now even without a Beta naming it should work because OSInstaller seems find automatically the "Install macOS app" available on recovery menu (I renamed it without "Beta" and installer automatically labelled Beta on menu), otherwise use that terminal link for InstallAssistant.

Also included "Boot plist fix" that doesn't patch Wifi kext (for those who have an 802.11ac ) and USBOpenCoreAPFSloader3 because some non-APFS Mac with DDR2 RAM might require a previous version to load opencore menu at apple startup manager.
