macOS 12 Monterey on Unsupported Macs Thread

[justperry]

So, in essence, it's...(On my 2012 Mac Mini)

Download and install on a USB stick/disk/ (external)partition.
Run micropatcher scripts on the installer.
Install or Update OCLP 1.7 or nightly on the EFI partition.
Startup from EFI, next choose the installer.....Wait


Yes????
I did it this way before the OCLP 1.7 or nightly, as said in an earlier post, it got hosed.

 

[pshufd]

Trying this out as I'm too tired to workout. This is really easy when you follow the directions. Well, so far. I'm doing createinstallmedia right now (something I've done 100 times).

How is the speed?
I am curious, I tried to install Monterey (beta) the evening it was released on my 2012 Mac Mini, *"back then" it resulted in a bogged system.

*How quickly this seems to have changed with HD4000 "support".

after download files with OpenCore post install patch, system is like Big Sur, I have little problem with safari (slow writing on forum like this for example) but for the rest is fully usable

 

[pshufd]

After picking EFI, it asked me for a username for recovery and then asked me for a password. I was worried that it would boot up Mojave but it dumped me in to the Install/Recover/Disk Partition GUI and I just proceeded from there. The installation is underway.

That extra bit isn't in the directions and it might be helpful for others that run into it. I also have two EFI boots as I set it up on the internal and the externals drive. I plan to run it on the external drive for a few days which will be a pain as it's a laptop and then put it on the internal after a week if there are no problems. I will be able to test the external monitor withing a few days (just need to disconnect the 2015 from the QHD monitor and then plug in the 2014. This is setup with HDMI though I have another monitor that I can test with Mini Display Port.

The fans are noisy, same as with the 2015 MacBook Pro installation.

 

[pshufd]

It's setting up my account. So 2014 MacBook Pro 15 installation is successful so far. WiFi and Bluetooth work. I need to verify cold start and do some testing with external monitors. The fans are really loud but they should get back to normal post-install. It seems like they are running all the cores on the CPU whereas maybe they limited the number of cores in Mojave and older.

Hi @jackluke or any other user Is there any chance to run Monterey on this MacBook Pro
MacBook Pro (Retina, 13 pouces, late 2013)
This machine run BS perfectly GPU Type: Intel Iris 5100 CPU Intel core i5 4258U
Thanks in advance

​

EDIT ***
Nevermind booting from OC wth a EFI I made and the install is possible now 👍
I will see after hope its work

EDIT 2
Everything's work I am surprise : the only thing is a bit slow boot before the Mac Chime

I'm happy to report that I have 12.0b1 running on my cMP 5,1 with OCLP 0.1.8. The OS partition is on a Samsung 860 SSD connected to a PCIe SATA 3 controller card. This is indeed a major feat, as it is widely reported on Macrumors and elsewhere that (particularly) 5,1's are not reliably able to boot beyond 11.2.3 without many hard (or eventually some, for the lucky ones) cold reboots - with, it appears, no-one yet able to do 20 consecutive reboots. [cMP 3,1, MBPros, Mac minis, iMacs seem less prone to this problem].

The only issue I can initially see is that neither of my ethernet ports are working with 12.0b1 - thankfully WiFi still does. I've read through this whole tread from page 1 but haven't yet read of a proper 'fix'. Any help would be appreciated. System Info shows that I have the following kext loaded for both ethernet addresses: /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/Intel82574L.kext. Hopefully this can get fixed with either a older kext injection into OC or further patcher updates or with later betas/releases from Apple.

Update: I installed the next OCLP 0.1.9 but that refuses to load 12.0b1 for me (it’s still ok on older OS’s). The verbose screen stalled randomly at any of the early NVMe/USB/Ethernet/LocalSigningPublicKey config/load lines on multiple tries. I returned to OCLP 0.1.8 and it booted up first pop. I’ll continue to try out this patcher version and report back on its success/hang rate [...not that good actually: about 1 in 7 boots. I must have fluked the easy initial installation and the later CCC backup and test with one reboot. It's been downhill since, trying off a cloned SSD copy. I think the slower original 5400rpm HD increased the chances, but that's not an ongoing solution, is it?!]

Background: Having previously not been able to get OCLP 0.1.5 or 0.1.6 running on my Mac (seems I'm an odd one out in this regard), I tried 0.1.7 last night and, to my surprise, it did run - getting to the picker screen. However, when I used it to complete my half-finished Monterey installation, that patcher version triggered a huge amount of nvram rebuilding, with 100(0)'s of lines of code flashing by for several minutes, then ultimately stalling. That rebuilding also corrupted my ability to boot back into 11.2.3, until I cleared the nvram and went back to a Martin Lo OpenCore package. As some bug was subsequently found quickly by the OCLP developers, 0.1.8 followed a few hours later and it seems to be a significant advancement for unsupported Macs overall. Well done to the developers!

I am testing Monterey beta 1 and Big Sur 11.5b3 on a Mac Pro 5.1 started thru OCLP 0.1.8

now writing from Monterey. To trigger the race condition I have now populated all 4 Sata Bays and 3 PCI Slots (GPU and 2 AHCI Apple Blades).

Both 11.5b3 and Monterey Beta 1 act exactly same: I cannot boot them when USB Stuff is plugged in (including internal Bluetooth Modul, but I let it unplugged all the time).

So my workaround is:

Boot,
wait till Open Core screen is visible,
select OS,
unplug USB (all is in one chain),
after the early boot phase I can insert USB back in. I even have seen in Verbose mode my USB stuff (Keyboard, Cinema Display, Mouse) is loaded.

So I assume the race condition in my setup gets triggered when the OS is scanning the volumes and it is finding USB Hardware. This point when it freezes at loading the Ethernet Drivers.

So during some tests EduCovas on our Discord noticed that enabling FileVault on a 2012 MacBook Pro in Monterey would crash the system. Originally we believed perhaps it was due to the modified root volume however after further inspection it seems Apple now has an AVX2.0 requirement on FileVault.

This seems to be entirely a bug on Apple's end as the Trash Can Mac Pro (MacPro6,1) doesn't support AVX2.0 and would trash as well. Anyone with Trash Can, I highly recommend verifying as well as reporting to Apple this bug. We would greatly appreciate Apple knowing and fixing as soon as possible

Could an instruction emulator like MouSSE (for some SSE 4.2) or OpEmu (for everything else?) be used to solve this?

[webg3]

Here I didn't need to autologin as I see many informing.
What I did was take an external hard drive, partition it, create the boot disk in one of the partitions on that external hard drive.
Then apply OpenCore Patcher 1.7; and then boot by this EFI on the external hd and start the installer, choosing the partition that was left as a clean install.
Following the setup screens at the end, after rebooting, apply Post-Install and fix Intel HD Graphics 4000.

MacBook Air 2012 11" 4GB RAM

 

[Bornee35]

Looks like another arbitrary cutoff. How different is the 2014 MacBook Air/Pro from their 2015 counterparts? I doubt there's much different between Haswell and Broadwell.

Spec list says they're identical, makes zero sense.

 

[pshufd]

Spec list says they're identical, makes zero sense.

The 2014 Pro has the same CPUs as the 2015 Pro. I have both. The difference may be due to the Discrete Options though. The 2014 offered nVidia dGPU while the 2015 offered the AMD GPU and we know that Apple had a falling out with nVIdia and stopped supporting their GPUs. There's also some funny rule about devices being sold in the past five years getting support. The 2015 MacBook Pro was sold as late as 2018 I believe and perhaps the 2014 wasn't sold in the past five years. Whatever the case, OCLP allows the 2014 models to run Monterey.

 

[pshufd]

I was able to install Monterey on VirtualBox by lowering the CPU count to 1. Unfortunately Monterey is pretty slow with this setting. I tried to change CPU to 8 after installation but this caused various problems. So I am going to set it at two to see if that's usable. The performance of Monterey on VirtualBox is much better than Big Sur. I did not see the very slow window opening and closing issues on Monterey. I need to do additional testing though. It is possible that I might just live with the two CPU limit if things are overall good enough.

There are lots of websites out there with directions on installing Monterey Beta 1 on VirtualBox but there are issues that aren't discussed in those web pages.

I'll have to give it a try when I work up the courage.

 

[pshufd]

Yeah, I know.

I did two Time Machine backups and installed it to an external SSD. Can you say just a bit paranoid? I recommend following the directions too. I tried to wing it and it didn't work. The directions work a lot better.

updated to OCLP 0.19, 2012 13" Macbook Pro, excellent work guys, apple watch unlock also works. thanks.

Yes,Yes, just installed Monterey Beta 1 on my unsupported Mac mini Late 2012 with HD 4000 followed step by step from post 557. Thank You.
one more thing Apple TV and some online steam video are not working. once play it was jume back to desk top.

 

[adam25255]

Anyone tried migration and clean install with Time Machine backup?
I did that, because upgrade with installer always failed and now, when I choose backup, button Next grays out after clicking on it and nothing happens. Or am I doing something wrong?

perhaps next beta release Apple TV streaming will get fix, google chrome browser playing youtube videos play well for me, Safari a bit buggy for playing videos.

I've not been able to get any upgrade installs to work. I found many examples of the problem in the Hackintosh and OpenCore communities including fixes but I don't know if they apply to Monterey.
