I also just got a mid 2012 Macbook pro and 2013 iMac. I also thought that they would at least be supported a few more years. It a shame that they are being not supported anymore since they are still capable machines.
How install?? I have MacBook pro mid 2009, MacBookpro5,5.
Work all?
Also I find it interesting that they still sold the 2012 while the 2015 was being sold. So in my mind the 2012 should get the same type of support that a 2015 should get.
THANK YOU ALL, this thread is so awesome! By following the instructions here I managed to not only install Big Sur on my (unsupported

Well, I will be Ok with this "hack" to install BS, that at least takes me forward to not buying another Intel Mac before the transition to arm, I will be buying a new one as soon as there's an arm proc inside.
And then this, no big deal but you quoted your own post, you might take the time to edit it.

How did you manage to get Wifi working?
"BIErrorDomain error 3" is a definitive indication that Hax.dylib (or Hax2.app/Hax2Lib.dylib, for people trying that instead) did not do its thing.
I am still rather puzzled how you ever managed to successfully run the Big Sur Beta installer on a MacPro 3,1 with or without the ROM patch applied. In either case, it should have prevented you from selecting an APFS target volume due to the firmware check failing in /Applications/Install macOS Beta.app/Contents/MacOS/InstallAssistant.
I don't think a binary patch will be needed. After all, the whole idea of @ASentientBot's Hax.dylib/Hax2Lib.dylib is to patch the installer as it runs, LD_PRELOAD-style. (Unfortunately I doubt I'll have a chance to look into doing this anytime soon, though. My needs right now involve Macs that are supported by High Sierra.)

Schools closed in March, and I was in my final year of secondary (high school). We would have set the Leaving Certificate Examination to determine our university place (no GPA system here, just one set of finals). That didn’t happen…so the teachers are ‘predicting’ our grades. I’m pretty much in limbo until September
I prefer the text menu too for differentiating. I like the dark background especially, but I doubt it is possible to modify Apple's default firmware on our Macs to make a fancy Apple GUI boot picker
I think kextcache was rebuilt for prelinkedkernel but it's not working yet.
The WiFi & sound kexts must have loaded, so maybe the errors in the Terminal output have some clues?
I will copy-paste my entire recovery & open Terminal output…but it's very long, so only read if you want

It is possible to change the VolumeIcons but they need a 32 bit icon format for apple startup manager, for Catalina you could try this: https://forums.macrumors.com/threads/macos-10-15-catalina-on-unsupported-macs.2183772/post-27499212
run the script directly from Catalina (and its Downloads folder).
About BigSur, to rebuild properly the kextcache try with this new @ASentientBot method from single user mode, this method requires snapshots disabled, so I guess you should first disable or delete the BigSur snapshots from its USB BigSur Installer or using my USBOpenCore booting the Recovery 10.16 (dmg)
Once you disabled the snapshots, this I write is for those who used my prelinkedkernel method with usbopencore, so boot using opencore then from its text menu use CMD+S (without holding) and select with keyboard the BigSur Label:
Code:
mount -uw /
cd /System/Library/Filesystems/apfs.fs/Contents/Resources/
./apfs_boot_util 1
./apfs_boot_util 2
chown -R 0:0 /System/Library/Extensions/
chmod -R 755 /System/Library/Extensions/
kextcache -i /
kcditto
rebootafter
kextcache -i /this will takes some minutes and during it you will encounter many "kext with invalid signature: allowed" but this is completely normal to make a BigSur prelinkedkernel.

Infact, as I wrote you need or to clone first a BigSur install, or you need to use the USBOpenCoreAPFSloader3 spoofing to a supported BigSur Mac, make an external usbopencore, and then I can send a spoofing modified config.plist for your machine, because currently the usbopencore doesn't spoof to any supported mac.
This should work without editing any binary or .strings file .
Guys please tell me how to go around this:
bash-3.2# mount -uw /
mount_apfs: volume could not be mounted: Permission denied
mount: / failed with 66
bash-3.2# mount -uw /
mount_apfs: volume could not be mounted: Permission denied
mount: / failed with 66
You should try this: https://forums.macrumors.com/thread...unsupported-macs-thread.2242172/post-28603788
You need to make with createinstallmedia an USB BigSur Installer and boot from there recovery environment.
Deleting BigSur snapshots will allow to use "sudo mount -uw /" from BigSur normal booting.
Thank you, yeah you have to do it from recovery as if you do this command from system it throws an error:
diskutil mount disk1s5
/S*/L*/F*/apfs.fs/C*/R*/apfs_systemsnapshot -v "/Volumes/OSX" -r ""
Attempting tagging of snapshot on volume: /Volumes/OSX
fs_snapshot_root: Operation not permitted
fs_snapshot_root failed with /Volumes/OSX
Is that spoofing related to SMBIOS (Board ID / Serial) key in config.plist?
