macOS 15 Sequoia on Unsupported Macs Thread

[MacRumors3590]

I found just using OCLP 3.0 nightly it patched

I tried this and it still gives an error while tring to patch.. Any help would be great!

I tried this and it still gives an error while tring to patch.. Any help would be great!

I’m unsure why I’m wondering maybe because I did the small OTA at about 900 mb up to 15.7.l or because it’s a mid 2014 model. I believe [mention]deeveedee [/mention] posted a solution , wait it out or will have to mod OCLP.

i have imac 27 2012 model 13.2 and cannot activate bluetooth nor wifi beside patching everything also open core patcher 2.4.0 and boot 1.3.0 efi any fix or help to get working in SEQUIOLA 15.6 everything else is stable Nvidia kepler works fine as well

I checked every Plist.config and did NVRAM RESET

thanks give me some solutions

Have you tried running this command in the terminal to stop- and restart bluetooth while logged in normally? It works for some situations:

sudo kill -9 $(pgrep bluetoothd)

• All pre AVX2 cMP and iMacs with upgraded Metal AMD dGPU should use OCLP 2.0.2 or later to avoid the VTDecoderXPCService crashes.
• Mac models with T2 chip have currently no support at all.
• AI functionality is limited to Apple Silicon and T2 based Intel Macs, so it will not work on OCLP upgraded Intel based Macs!

Spoiler: Macs capable of being patched to run Sequoia:

From version 2.0.0 onwards OCLP will support Sequoia! OCLP supported Intel Mac models are listed on GitHub, only. Reading the OCLP installation documentation and OCLP version the CHANGELOG is always useful. Most limitations are listed in several GitHub issues, the most important one is about GPU issues.

Please also read this fully before downloading anything, or we'll be very disappointed...

As usual, this is still a new operating system and a bleeding-edge patcher version. Don't try this if you're not already familiar with OCLP, don't try this if you're not willing to have to deal with any data loss, and especially don't try this if you don't know how to troubleshoot.

Please do not blindly update your only single working macOS environment on your one and only single Mac without reading the next section!

Spoiler: Necessary preparations:

To avoid any frustration or even worse data loss please create and maintain backups on a regular basis. Before performing a major and even before doing a minor macOS update create a new backup.

Update the firmware of your Mac and keep it up to date! We do not provide support for not proper managed Macs.

Do not swim ahead of the swarm of macOS users, you have an unsupported Mac, neither Apple nor the OCLP developer team will recover your system. If you nevertheless believe installing beta software with development patchers on unsupported Macs is a great idea you will discover quickly nobody can or will help you. Follow the swarm. Observe posts and read about new problems and do not ask if is is safe - it is not!

Look up Apple support pages how to manage and create multiple parallel macOS installations using APFS volumes. Keep the latest working macOS and create a new test environments with new test users before messing with your single working Mac. A lot of problems are related to incompatible settings inherited in a decade of macOS updates and from incompatible third party software.

Finally:
Keep the USB installer with OC created with the OCLP app. This is an external recovery option. The internal recovery can be accessed after pressing the space bar on the OC boot picker. Do not disable this picker unless you know how to make it visible, again - by pressing ESC on boot.

Open the system preferences and the softwareupdate pane and disable all automatic actions. Do not preload, do not auto install updates, or auto install security patches. This may break your OCLP based installation.

Spoiler: How to support the OCLP development?

After many requests, we've finally opened up a way for people to make monetary contributions to OCLP's development, using Open Collective: https://opencollective.com/opencore-legacy-patcher If you appreciate what we do, please considering donating! Your support will help us purchase needed hardware to improve the project.

Thanks!

Spoiler: Third party application problems (this section should to be maintained by users!!):

Patching means adding back software parts from older macOS versions into recent versions. This way we will not be able to use most recent technology and feature enhancements. Apple likes to show those in their own (sometimes macOS included) applications like Maps, Photos, FinalCut, Garageband, LogicPro, Pages, Keynote, Numbers. So please get and save those software version running on older macOS versions before updating applications. You might end up with a new version not running on the latest macOS.

Before reporting an error here please first check if you have really the latest app version installed and if this app supports Sequoia at all.

This happens mostly to users of pre 2011 non metal Macs, but lately also with metal Macs using Kepler and AMD GPUs 20

1. Google Chrome on MacPro6,1 or MacBookPro 2015 with red windows (all Macs using AMD GCN1-3 graphics cards)

Spoiler: Things one will never be able to fix or simply need new hardware!

Over the years Apple introduced a lot of new software features relying on real new hardware. Sometimes because of execution speed and latency induced by older hardware, sometimes because of new features like WiFi ac, Bluetooth 4.0, 4k HEVC and 4K H.264 support.

Another serious threat is the use of modern AVX2 Intel CPU instructions available only on Late 2013 and newer Mac hardware. The Metal rendering framework is in the middle between this, but without any documentation one would have to write device drivers for other GPUs to achieve support. This is beyond this project.

iPhone mirroring needs a T2 chip, so all older Macs will never get it. And to make things worse: Macs with T2 have currently no OCLP support.

So a lot of features like AirDrop, Universal Control need BT4.0 and WiFi ac, modern Apple and third party apps using the metal framework, recent Adobe software using AVX2 with Ventura+ will simple break your Mac in a way OCLP cannot ever fix it. Even if installing and booting of a recent macOS works fine some or a lot of apps will not work properly.

We had this clearly defined Metal border which puts all non-upgradable hardware released until late 2011 into the big non-Metal camp. Now we have a 2nd group of 2012-2013 Macs including the MacPro6,1, Metal GPU upgraded MacPro3,1-4,1-5,1 and iMac10,1-12.2 all lacking AVX2 support and a third group of legacy Metal systems from late 2013-2015 - either with AMD GCN 1-3 and Nvidia Kepler dGPU, Intel HD4000 and Haswell iGPUs with different and difficult to address issues.

The most compatible but unsupported Intel Macs with dGPU have AMD GCN4 models and were released after 2016/2017.

Spoiler: How to revert back to the last or former supported macOS?

You read the “Necessary Preparations” section before starting the OCLP adventure? So you have a backup and can continue.

If you want to go back to High Sierra or older you need to wipe the disk, now. HS uses a different version of APFS not compatible with any version used on Big Sur an later.

If you have no backup and the new target macOS is Mojave or later and if your SSD is big enough and your new target macOS will run on APFS you may get around this mess. Install the new macOS in parallel. Look up Apple support pages how to manage and create multiple parallel macOS installations using APFS volumes. After booting it you can migrate your user data over. Finally delete the Sonoma volume group using Disk Utility, again.

In general:
To revert back to the last supported (by Apple) macOS version you must erase your disk or the Sequoia volume group on APFS as there is no uninstall option provided by Apple and there is no way around this. You should follow Apple supported methods to get back, but create a user data backup before starting to erase the internal disk! Restore user data without settings, these are in general not compatible when going back.

Have you tried running this command in the terminal to stop- and restart bluetooth while logged in normally? It works for some situations:

So is version 3.0 the next version of OCLP that we're waiting on for a public release? I saw mention of a version 2.4.2, so not sure if that was a typo on the person's behalf who typed it, or if it's coming before 3.0. I haven't seen either one offered yet.

Edit: the 2.4.2 reference was on the Sonoma thread, as that's where I'm staying right now as the sweet spot. It seems like it's more active here though, and that's why I still post here as well.

*** This post is relevant only to those who are using BluetoolFixup.kext 2.7.0 and later. If you generated your Open Core EFI with OCLP 2.4.0, this post does not apply. ***

For working Bluetooth in Sonoma 14.7.7+ and Sequoia 15.6+ on my PC emulating SMBIOS MacBookPro6,2, I needed to add BluetoolFixup boot-arg -btlfxboardid to my Open Core config.plist:

boot-args: -btlfxboardid

For those that know how to implement this change, I'd be interested to know if this boot-arg fixes broken Bluetooth for real Macs.

EDIT: I haven't looked at the BluetoolFixup.kext changelog, so I'm not sure if this is important: I have updated my Open Core EFI with BluetoolFixup.kext 2.7.1. OCLP 2.4.0 creates the Open Core EFI with BluetoolFixup.kext 2.6.9.

EDIT2: I checked the commits to BluetoolFixup.kext after 2.6.9 and see that the automatic BoardID patch was removed AFTER version 2.6.9. Since OCLP 2.4.0 uses BluetoolFixup.kext 2.6.9, there is no need for boot-arg -btlfxboardid when building the Open Core EFI with OCLP 2.4.0.

Mac Mini 2014 OTA 15.6 to 15.6.1 with 2.4.0 no problem.

 

[Kevo]

15.6.1 installed on mid 2012 MBP without issue. (OCLP 2.4)

 

[deeveedee]

Easy OTA upgrade from Sequoia 15.6 -> 15.6.1. Applying non-metal Nvidia post-install patches with OCLP 2.4.0.

Safari Technology Preview 226 released today now has the same bug with Compact Tab layout as the Safari 26 Beta. 😕

If someone wants to install it anyway:

https://swcdn.apple.com/content/downloads/55/43/093-20304-A_B69UB2Y766/qu8us70m6l0anhiu3m70dlpquzrpf0qf2o/SafariTechPreview.pkg

It still doesn't have the redesigned extensions section.

The link for 225 I posted yesterday will get you 226 now too.

15.6.1 installed on mid 2012 MBP without issue. (OCLP 2.4)

MBP11,1: three updates.
Internal SSD (production disk) from 15.6 to 15.6.1 with USB installer, OCLP 2.4.0 patching. Very smooth.
External SSD from 15.7RC 24G210 to 24G214, USB installer, OCLP 2.4.0 patching. Needed very long from entering pw to desktop after installation while not yet patched. Working with my full user data put to the external SSD as CCC data clone from internal SSD.
(Tahoe: 2nd external SSD from 26.0b6 to b7, USB installer, OCLP 3.0.0n modified as described earlier for patching (very limited, no graphics other than in /L/E). No such user data in place. Smooth.)

All this while traveling, backup SSDs always with me. I've justified confidence in OCLP, thanks developers!
The MBP5,2 will be updated at home.

 

[F1Mac]

Flawless OTA update from 15.6 to 15.6.1 on Mac Pro 6,1 with OCLP 2.4

 

[TOM1211]

Did the next 15.7 RC and while downloading the update OCLP downloaded a KDK and patched accordingly, no issues again on my mid 2014 didn’t have to change anything.

 

[hvds]

Did the next 15.7 RC and while downloading the update OCLP downloaded a KDK and patched accordingly, no issues again on my mid 2014 didn’t have to change anything.

in my MBP11,1 case it is "KDK-less" patching: no KDK downloaded. May change once OCLP fully adapted to Tahoe. Metallib support downloaded in principle, but in this case, only the 15.6 one available so far, and already installed, so none downloaded for either 15.6.1 or 15.7rc.
Will be just the opposite with non-metal MBP5,2, will report on Saturday.

 

[MacMorrison]

I upgraded to macOS Sequoia 15.6.1 on an external drive using OpenCore Legacy Patcher 2.4.0 on my 2015 MacBook Pro 15 inch (MacBookPro11,5) with no issues.

 

[rehkram]

FYI both Macs (1 supported, 1 unsupported) running 15.7 RC3 here detected & installed new Safari Version 26.0 (20622.1.22.11.11) successfully today.

 

[shloimy95]

Well, that makes two of us LuckyOldMan!
Could one of the devs look at this and see if some "drivers" have been missed in OCLP for certain models like the 2015 MBA 7,2 and MBP 12,1?

I may be the third lucky one with a Macbook Air 6,2. SD card reader has not been working for some time now. I assumed it failed due to age, I have had that before with laptop card readers. Just the 4 lines in system report both with 15.6 and 15.6.1. Will test under Windows and report back later.

in my MBP11,1 case it is "KDK-less" patching: no KDK downloaded. May change once OCLP fully adapted to Tahoe. Metallib support downloaded in principle, but in this case, only the 15.6 one available so far, and already installed, so none downloaded for either 15.6.1 or 15.7rc.
Will be just the opposite with non-metal MBP5,2, will report on Saturday.

MBA 6,2 also KDK-less. 15.6.1 patcher used installed 15.6 Metallib and works fine. I see on Github Metallib 15.6.1 is now released, planning on waiting for 15.7 to be released before updateing.

 

[winxmac]

I upgraded to macOS Sequoia 15.6.1 on an external drive using OpenCore Legacy Patcher 2.4.0 on my 2015 MacBook Pro 15 inch (MacBookPro11,5) with no issues.

I have the one without the discrete graphics but still on 15.6 clean install.

Fairly new to OCLP but tried Hackintosh before. Do I have to re-apply patches after updating to 15.6.1 or no need to?

 

[mib01]

I installed 15.6.1 using OCLP 2.4.0 on the Macbook Pro 2017 15" and it's ok. The only thing is that OCLP didn't download the KDK, at the end of the update I just needed to run the post install to reinstall the Wi-Fi.

Yes, re-apply the OCLP post-install patches after updating to 15.6.1.

@Neon Ball I just wanted to mention regarding our conversation several months back regarding 4K YouTube on Safari, and OCLP. I had shown you that I was working on Monterey (native install) on iMac 17,1. Well, it also works under Sonoma with OCLP on the same iMac, so it's only Sequoia that gets limited to 1080p. Just wanted to pass that info onto you.
Edit: Adding Screenshot of a video labeled as 16K playing at 4K, on Safari 18.6 OCLP 2.4.0 iMac 17,1 running 14.7.8.

 

[shloimy95]

More info and fix regarding SD card reader in 15.6.1. MBA 6,2.
I tried with a Sandisk card in Windows it did not show up. I rebooted to MacOS with the card still in the machine, it took a very long time for the OCLP boot picker to show, but when MacOS loaded the card was showing on the desktop. I rebooted again without the card then inserted the card it works as expected. Same with Windows. It seems a SD card must be in the machine for startup at least once for OCLP to initialise the reader correctly.

Well I was going based on the 2015 15" MacBook Pro which has an R9 M370X which is also GCN, neither of these AMD GPUs have decode support and Safari is limited to 1080p h264 (AVC) here on native Monterey.

I don't really know what else to say at this point.
