This way we can all check it with different eyes and minds. Then confer in how it could work or not work etc. we could either pick time in the evenings to meet on discord or have a Google Docs that I shared and upload findings and or patches etc.

My theory is that if we could figure out the Boolean or other variable in the installer for Tahoe tells the installer to update firmware. Then we could patch the value to not install the update. This may allow us to install stage 2. It seems it is mainly the firmware update that is our problem.

Now technically there is one thing I did not test. It is very risky if it does work. One of three things could happen 1. The installer finishes and updates the firmware on the unsupported T2 mac, 2. It does the firmware update and bricks the Mac, or 3. It doesn’t change the point of failure and we get the error and nothing happens.

Here is the information I’ve come up with and want to research together.

However the board-Id in ioreg is still the real one of the MacBookAir8,1. That has to be the only thing holding the installer back. I did recompile RestrictEvents.kext with a couple fixes for warnings in Xcode. Now the kext loads and the usb installer goes back to its normal problem of not getting past the language screen. However I can boot into Sonoma and launch the installer. It just sees the board-id then stops at the normal incompatibility screen. However the RestrictEvents.kext is loaded as well as Lilu and others.

I tried to use an ssdt to hotpatch the board-id but no luck.

The thought process for me now is a way to either spoof the board-id with SMCSpoof.kext or something of that nature. I haven’t tried it yet. When I get home I will make an attempt.

I do think the reason RestrictEvents.kext prevents apfs from doing its job is because of the patches being done at the incorrect offsets for Tahoe 26.7 or something to do with the firmware of the MacBookAir8,1. If at all possible could one of you @Medelcartelinc @albert-mueller find or tell me how to find the offsets it is supposed to be patching. Also “ osbundlelibraries” has new additions in the Tahoe 26.7 version of the kext vs the one in Sonoma and I am going to assume Sequioa as well. That may need to be hooked in RestrictEvents.kext somehow for it to load properly.

updated RestrictEvents.zip

This is the zip of the new kext version I compiled on Tahoe 26.7 and fixed the warnings in.

So either we need a way to patch the installer (running it on desktop through Sonoma, internal partition installer of Tahoe installer, or usb installer) or a way to help RestrictEvents.kext to be able to properly execute the patches. Another way could be to patch “AppleACPIPlatformExpert” class/kext and patch the board-id manually at least for install.

On my iMac 2017 I had Sonoma happily installed using OCLP and everything worked fine, when I stupidly upgraded to Tahoe from the Mac's system settings... I managed to install it using OCLP-T2 but my audio (both speakers and mic) and the ethernet network stopped working. I had to buy an external ethernet usb interface but for my audio I'm toast and I have to use headphones.

Anyone in the same situation? I'd like my speakers and microphone to work again.
Thank you.

I used OCLP T2 4.0.0.180010.1 (4.0.0 alpha 18.10.1) to install macOS Tahoe 26.7 on my 13-inch MacBook Pro (2016, MacBookPro13,2).

Wi-Fi does not work.

There is no graphics acceleration / graphics driver.

I would like to know whether MacBookPro13,2 is not supported by OCLP T2 yet, or whether I may have done something incorrectly during the installation process.

      Good evening!


I successfully installed macOS Tahoe on my MacBook Pro 14,1, and I'm happy to say that the system is running very smoothly.


Audio and video are working perfectly, with no issues so far. The only problem I haven't been able to solve is the Wi-Fi.


I've already applied the available post-install/root patches, but Wi-Fi still isn't working.


Does anyone have any suggestions or know if there is a specific patch, kext, or configuration that I should try for this model?


Everything else is working great — Wi-Fi is the only thing missing!


Any help would be greatly appreciated.


Thank you very much!

What do you think? I have a framework of ideas on what to do and possible tests.

      Supported Non-T2 & T1 Macs

    

  • iMac: 21.5" & 27" (2017–2019)
    • 

  • Mac mini: None (for right now, please be patient)
    • 

  • MacBook Air: 2018
    • 

  • MacBook Pro: 2017 Non-Touch Bar and 2017-2019 Touch Bar (T1 Chip)
    • 

  • MacBook (12-inch): None (for right now, please be patient)
    • 

  • Mac Pro: None (for right now, please be patient)*
    • 



Feel free to edit when older Macs can install Tahoe. I will no longer be involved with the project.




⚠️ Disclaimer: Pre 2017 Macs may work however results on may vary. You will have to download MetalLibPackages which even then I don't recommend doing right. This also applies to the 2017 MacBook Air which has the same chipset as the 2015 with slightly higher clock speeds. Risks include; No Graphics Acceleration, Kernel Panics and Shutdowns. If you somehow have graphics acceleration and WiFi working on your Pre-2017 Mac (and 2017 MacBook Air) you will have to use MyKextInstaller, the 26.5.2 KDK and the AppleALC kext to restore audio.Always create a Time Machine backup before upgrading.






Recommendations for Best Performance


For the smoothest experience on macOS Tahoe, a 2017 or newer Mac with a discrete AMD GPU (Radeon Pro 555/560/570/580) is with 16GB of RAM is strongly recommended (8GB of RAM will work but results will vary based on user). An SSD (internal or external) is strictly mandatory.




Step-by-Step Guide


    

  1. 

    Download Required Files:
    

      

    • Download the latest OpenCore Legacy Patcher (T2 Fork).
      • 

    • Download the matching Kernel Debug Kit (KDK) .dmg for your target build (e.g., 26.5.2) from Dortania's KDK repository.
      • 

    

    2. 

  2. 

    Create Installer & Build OpenCore:
    

      

    • Launch OCLP-T2 and download macOS 26.5.2 or Older (26.6 and newer has no KDK available yet)
      • 

    • If app crashes, you must go to terminal and copy and paste the bootable install command for Tahoe: sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
      • 

    

    3. 

  3. 

    Install macOS:
    

      

    • Launch OCLP-T2 fork again and Build and Install OpenCore onto your External Drive
      • 

    

    4. 



    

  • Reboot holding Option (⌥), select EFI Boot from the USB, then select Install macOS.

      

    • Run through the installer (do not wipe your drive as you will lose Wi-Fi).
      • 

    • Complete the initial Setup Assistant (you can skip Apple ID setup during first boot).
      • 

    

    • 



    

  1. 

    Install OpenCore to Internal Drive:
    

      

    • Open System Settings > Privacy & Security > Full Disk Access, click +, and add OpenCore-Patcher.
      • 

    • Launch OCLP, select Build and Install OpenCore, and install it directly to your internal drive.
      • 

    • Reboot, hold Option (⌥), and select the internal EFI Boot.
      • 

    

    2. 

  2. 

    Apply KDK & Root Patches:
    


    3.

      There's a glitch in sleep mode where if you enter sleep mode, minutes later the Mac will turn on and show a grey screen. This is caused by a corrupted driver with OpenCore and your AMD GPU (if you have a Intel GPU, this will still work if needed).


If you need sleep mode, Launch Terminal and disable "hibernation" with the commands sudo pmset -a hibernatemode 0 and sudo pmset -a autopoweroff 0. Then, Power Nap (you can also use System Settings then Energy), sudo pmset -a autopoweroff 0 and disabling standby delay sudo pmset -a standby 0.


After, you need to rebuild and Install OpenCore on your Mac and reboot. Try using sleep mode for at least 5 minutes before waking your Mac and if your Mac no longer shows a grey screen, you have successfully fixed this issue however, if the issue isn't fixed, try resetting your NVRAM.

      Hi there I mentioned on Reddit (Key-Wolf8548) that you may be able to patch time out for SEP access using kernel patcher in OpenCore. I see you deleted the repo with the Lilu plugin so can you give me that details of the patch needed, or a copy of the plugin code for me to take a look at?


FYI I'm quite well know as DrDonk online having built patchers for VMware and macOS over the years. I couldn't get the Reddit name so have a generated name over there.

      How to Fix Audio in macOS Tahoe (26.5.2 and older) for Non T2 Macs

      This is the first and easiest way to get audio working in macOS Tahoe (26.0 to 26.6 Beta 4)

Step 1. Download the latest version of OCLP T2

Step 2. Download the KDK for corresponding macOS Tahoe version

Step 3. Open Finder, Downloads then select the Kernel Debug package file

Step 4. Download the Package (should take 1-2 minutes)

Step 5. Launch the latest version of OCLP T2 and apply root patches as normal


If the KDK doesn't fix audio after root patching follow the guide below.


This is for anyone who needs help to fix Audio in macOS Tahoe after applying root patches. Tested on Non T2 iMac (should hopefully work on T2 but untested)

Requirements: KDK and ALC kext downloaded (The HDA kext will not work)

Step 1. Download MyKextInstaller (https://github.com/Mirone/MyKextInstaller)

Step 2: Download the AppleALC Kext (it says on GitHub MyKextInstaller to use the HDA kext but when you're inside the app itself you have to use the ALC kext) https://github.com/acidanthera/AppleALC/releases/tag/1.9.7

Step 3: Launch MyKextInstaller

Step 4: Click on Install kexts

Step 5: Select the AppleALC.kext file

Step 6: If prompted to install the HDA kext, say No.

Step 6: Reboot your Mac (you won't have to rebuild or install OpenCore or redo Root Patches until the next macOS release)

There's NO KDK for 26.6 or 26.6.1 yet so stay on whatever version of macOS Tahoe you’re running for now. To work around screen sharing exploit enabled Firewall and block all incoming connections!
