macOS 14 Sonoma on Unsupported Macs Thread

[marcatrainbow]

Hi Forum could you help me,

I have updated my 2014 iMac 15.1, to Sonoma 14.5 using latest Opencore version 1.4.3,
and the Os installs ok but when reboots the computer is stuck at 25% progress and the fan just spins, I have tried reinstalling using the 14.5 version downloaded from Apple and created a boot USB using Opencore and the same thing happens. I have been using OpenCore to update to the latest OS since Monterey with no previous issues. Is there a way to fix this boot issue? Would appreciate any help as don't look forward ti reinstalling all my music software and plugins.

How many times did it reboot by itself? What happens when you boot up in safe mode?

@amaze1499 "Have you tried turning it off and on again?" Yes. Sometimes a cold restart may fix a boot hangup. A power re-set too. Unplug from power source after shut down. Press/Hold the power button for a few seconds. Restart and preform a NVRAM reset.

I have successfully updated my 2 Unsupported Macs to 14.5 with OCLP 1.4.3.
2014 MacMini 7,1 i7 16GB/500Gb
Late 2015 iMac 17,1 i7 64/1TB
My trusty update method is:
Backup with CCC
Download "InstallAssistant.pkg" (Thanks to Mr.Macintosh for the links)

macOS Sonoma Full Installer Database. Download Directly from Apple! - Mr. Macintosh

Download macOS Sonoma full installer with one click straight from Apple! Every version of Sonoma Beta & Final available all in one place!!

mrmacintosh.com

Installing into each machine's Application folder. This saves me doing 2 OTA downloads.
Run Onyx/Maintenance
Re-Start
Install macOS Sonoma
Install root-patches
Re-Start
re-run Onyx/Maintenance
Re-Start.
So far OK on both Macs with Sonoma 14.5.
BIG Thanks to the OCLP Developers!
~And all the helpful people here on MacRumors!!

The install seems to stop at 25% after the 3rd restart, I have reinstalled the software many times, reset the NVRAM, tried in recovery mode using terminal and the mrmacintosh fix and the computer will not restart in safe mode.?

How long did you give it before you decided it might have frozen? Consider giving it longer - my cMPs give the impression they have frozen but I just wait a few minutes longer and they complete.

You’ll need patience and a few more reboots. I had experienced a similar behaviour, even when trying to boot into safe mode. You get there eventually.

When did the iMac Pro drop native support, was it Ventura, or Sonoma? I know they kept support a bit longer than earlier non pro iMacs, just don't remember which version.

imac pro 2017 takes sonoma natively. i have an imac 2017 21 inch and it stops at ventura.

One short question.

Is it possible to get two Displays to work with a mac mini 2012 or 2014 with Open Core Lagacy Patcher (Sonoma) ?

If yes, how ?

1x HDMI 1x Thunderbolt ?

Does also work 2x Thunderbolt ?

If you are trying a specific configuration with OCLP and having issues, please describe the configuration and issues.

These are my personal general recommendations. YMMV.

I can't speak to the 2014 Mini, but I went through every possible Mac OS version that the 2012 could run over the years, with many combinations of dual displays.

With the 2012 I found it was best to use the Mac Mini HDMI port as the primary display to a display with a native HDMI connection. HDMI port to a DVI monitor with a good HDMI/DVI adapter also works. Trying to use the Thunderbolt output for primary video always seemed to end up at some point with the Mini forgetting what display to use.

For the secondary display with the Thunderbolt/Mini DisplayPort connection, I would recommend a digital display using a good quality cable without any other kind of adapter or format converter.

So, Mini DisplayPort cable from the Mac Mini to a display with HDMI input using a Mini DisplayPort to HDMI cable, or Mini DisplayPort to DisplayPort, or Mini DisplayPort to DVI.

Stay away from any kind of Mini DisplayPort to multiple output video cable, especially if you want to use a VGA display. If you want to use a VGA display, get a Mini DisplayPort to "active" VGA cable.

Try safe boot and install root pathces and reeboot or install OCLP 1.5.0n in safe mode

You can manually edit the config.plist to delete this NVRAM variable and do a deep NVRAM reset to remove the variable from NVRAM. You could also have OCLP build your config.plist with SIP fully enabled.

That being said you may need SIP lowered or off to boot Catalina with patches to allow it with a non-metal GPU. That's why I suggested you check the thread about Catalina (or Mojave) on unsupported Macs to see what specifically was recommended at the time. The security model for Sonoma is different than Catalina (or should I say evolved and more locked down) so what is required for Sonoma on non-metal may be very different than what is required for Catalina.

Thanks. But I found some time today and found out exactly what the problem was. Since Dosdude's SIP patch makes changes to the system, no matter what value I enter in config.plist, it has no effect. Because I have already applied the patch from the system. I will reinstall the system from scratch and not apply the SIP patch, but I will allow the OC to intervene and disable SIP from the config.plist.

What does the csrutil command (in terminal not in recovery) report for your SIP setting with dosdude?

I was not aware that a system patch other than an NVRAM variable could affect SIP for every boot. The config.plist is writing a variable and value to NVRAM that then controls SIP on every boot.

Curious to understand what you find.

In this post, he explains exactly how his SIP.patch interferes with the system. Its patch permanently patches the system file and SIP is always disabled. Even if the OC writes the values we manually added to the NVRAM, it does not actually activate it because dosdude's patch prevents this.

By the way, even if you intervene from recovery, it does not help. His patch makes SIP always disable.

macOS 10.15 Catalina on Unsupported Macs

Because system files are patched, and extra, unsigned kexts are being installed, SIP must remain disabled at all times when running a patched copy of macOS. Having SIP enabled will cause the system to simply stop booting, or have functionality issues. Catalina Patcher includes an implementation...

I just spent an hour reading bits of this thread from the beginning. Then skipped to the middle, and now hopping to the end. I have a question, but before asking, I need to say, "Holy Moley!" There are many cases of serious heroism that have already unfolded and accomplished miracles...

EDIT: @telepati Not sure if this helps you, but I used DosDude's patcher with CLOVER boot loader here.

In my CLOVER config.plist,
CsrActiveConfig = 0x067 (might need to be adapted to Open Core)

 

[candidosoares]

Why do I get this black screen on CapCut? - Sonoma 14.5
Parralels Desktop also receives this same black screen.
OLCP 1.4.3 iMac 5k 2014 AMD Radeon R9 M295X 4GB

I've already tested Sonoma 14.5 and the same thing happens, I've tested all the color profiles, it doesn't work

Edit: cause of blank screen is driver wireless install after install OLCP 1.4.3

Hey guys. Did any of You successfully install Sonoma on A1466 2015 model? If so, did following the basic instruction of opencore work or are there any extra steps to be taken?

Got it. As I never used dosdude's Catalina patcher I didn't realize that's what he did. It makes sense - similar to what OCLP does because it's patching system files and requires SIP to be lowered. OLCP just does it through NVRAM.

Were there any updates issue under item 2.
When using FaceTime on MacPro 6,1 14.4.1 and latest nightly can connect to or be called by 3rd parties no problem, but after initial connect and very brief video, video of the other caller/participant reverts to their non-video display screen the same as an audio call, with audio connection still working fine. Apologies if I missed any work-around in the thread..

As far as I know, this hasn't been fixed yet. I even don't have a brief video.

Imac27,13.2/Sonoma 14.5==When I updated to OCLP 14.5n I could not find "disable SIP" in settings is that done automatically now when it is necissary for different iMac models?

Besides downgrading to the last supported MacOS (Monterey in this case for MacBook 9,1 now with f/w 526.0.0.0.0), is there any way to force a MacBook 9,1 now running Sonoma 14.5 final with OCLP 1.50n to the last available firmware update (possibly 529.1.0.0.0). I think not but live in hope!

Possible.

Create a new apfs volume (for native macOS). Install to that volume. Boot into that, run all OS updates.

Once the firmware is updated, you can either leave the dual boot volume there or erase it.

I did not find any other way. However it doesn’t have to be a downgrade. Simply booting and updating from a supported OS on a different drive will do the job as well. At least that worked in my case. I just swapped the internal ssds to get the job done.

 

[LlamaLarry]

Yeah, I swapped from my third party storage in my 2015 MBA to a $18 OEM one so I could update the firmware (by OS Recovery of the latest macOS).

 

[coolio2004]

Strange - silentknight doesnˋt find a new firmware update with native Monterey on my MBA7,2.

because its the latest firmware available for that product:
