Need new KDK. Don't use the KDK15.5 if you're manually patching the system volume. It broke mine 🤣 

Had to restore snapshot 👍

Easy update after disabling Bluetooth and rolling back patches.

Someone has a problem with CGPDFService?

It appears after update to 15.6 while famous on real Mac in 2024.

To all:

 

Update stuck at 28 minutes on my old Ivybridge (SMBIOS MacPro6,1, Opencore, OCLP 2.4.0). Any ideas, please.

No one can tell unless with verbose

@Matgen84, before updating you must revert the OCLP patch.

Anyone here not getting incremental update of Tahoe after updating to 15.6?

There is no issue on 15.5

@LockDown Just my opinion: incremental update of Tahoe from macOS Sequoia 15.5 or 15.6 don't exist because Tahoe is a new OS.

[LockDown]

@Matgen84 it does. enable the beta and you will get incremental. But not in 15.6

@LockDown Thanks.  Something is changing or corrected between 15.5 and 15.6 ? 

Sorry for bad English.

posssibly. Im sure it has nothing to do with RestrictEvents, else we won't be getting incremental update in Tahoe either

### **Forcing Aquantia Ethernet (AQC107/AQC113) on macOS 15 (Sequoia)**

Since macOS 15 (Sequoia) is still in early development, Apple may have changed kernel structures, but the general approach remains similar. Here’s how to patch Aquantia support **without OpenCore's Kernel Patches**:

 

---

 

## **Method 1: Direct Kernel Patching (Recommended)**

This modifies the kernel to bypass Aquantia's device ID checks.

 

### **Steps:**

1. **Disable SIP & Authenticated Root**

   - Boot into **Recovery Mode** (`Cmd + R` at startup).

   - Open Terminal and run:

     ```bash

     csrutil disable

     csrutil authenticated-root disable

     ```

   - Reboot.

 

2. **Mount the System Volume as Read-Write**

   ```bash

   sudo mount -uw /Volumes/YourMacOSVolume

   ```

 

3. **Locate & Backup the Kernel**

   - The kernel is now in a **Kernel Collection (KC)** in macOS 15.

   - Find it at:

     ```bash

     /System/Library/KernelCollections/BootKernelExtensions.kc

     ```

   - Make a backup:

     ```bash

     sudo cp /System/Library/KernelCollections/BootKernelExtensions.kc ~/BootKernelExtensions.kc.backup

     ```

 

4. **Hex-Edit the Kernel Collection**

   - Use a hex editor (e.g., **Hex Fiend**, `xxd`).

   - **Search for:**

     ```

     81 FB 91 55 00 00  # Checks for AQC107 (0x5591)

     ```

   - **Replace with:**

     ```

     81 FB 90 55 00 00  # Bypasses the check (changes 0x5591 → 0x5590)

     ```

   - Save changes.

 

5. **Rebuild the Kernel Cache & Create a Snapshot**

   ```bash

   sudo kmutil install --update-all

   sudo kcditto

   sudo bless --folder /Volumes/YourMacOSVolume/System/Library/CoreServices --bootefi --create-snapshot

   ```

   - Reboot.

Smooth OTA upgrade to Sequoia 15.6 on my HackBookPro6,2.  

 

Broadcom Bluetooth stopped working (in Sonoma 14.7.7 and newer macOS).  To fix Bluetooth, I needed to add BluetoolFixup boot-arg -btlfxboardid.  See details here.

 

EDIT: The cause of this problem was not a change in macOS, it was a change in BluetoolFixup.kext.  Auto board-id patching was removed from BluetoolFixup.kext in version 2.7.0.
