When running macOS in a virtual machine, you may encounter problems logging into Apple services including:

- Apple ID

- iMessage

- iCloud

- App Store

This happens because Apple's services can detect that macOS is running in a virtual environment and block access. The solution is to apply a kernel patch that hides the VM presence from Apple's detection mechanism.

NOTE as per forum post: Unfortunately, this would very possibly break qemu-guest-agent, which is necessary for the host getting VM status or taking hot snapshot while the VM is running. This is because qemu-guest-agent also checks the hv_vmm_present flag, but only works if it is true (=1).

Use at your own risk. Hope it would help.

This guide provides three methods to apply the necessary kernel patch. All methods implement the same fix originally described in [this forum post](https://forum.proxmox.com/threads/anyone-can-make-bluetooth-work-on-sonoma.153301/#post-697832).

Before proceeding with any method:

- Make sure you can access your EFI partition

- Locate your OpenCore `config.plist` file (typically in the `EFI/OC` folder)

- Back up your current `config.plist` before making changes

This is the fastest and easiest way to apply the patch.

1. Mount your EFI partition using Clover Configurator or another EFI mounting tool

2. Download the patch script:

```bash

curl -o apply_appleid_kernelpatch.py https://raw.githubusercontent.com/sickcodes/Docker-OSX/scripts/apply_appleid_kernelpatch.py

```

3. Run the script with your `config.plist` file path:

```bash

python3 apply_appleid_kernelpatch.py /path/to/config.plist

```

**Pro Tip**: You can drag and drop the `config.plist` file into your terminal after typing `python3 apply_appleid_kernelpatch.py` for an easy path insertion.

**Note**: If you encounter a "permission denied" error, run the command with `sudo`:

sudo python3 apply_appleid_kernelpatch.py /path/to/config.plist

If you prefer a graphical approach:

1. Open OCAT and load your `config.plist`

2. Navigate to the **Kernel** section

3. Go to the **Patch** subsection

4. Add two new patch entries with the following details:

| Setting | Value |

|---------|-------|

| **Identifier** | `kernel` |

| **Base** | *(leave empty)* |

| **Count** | `1` |

| **Find (Hex)** | `68696265726E61746568696472656164790068696265726E617465636F756E7400` |

| **Comment** | `Sonoma VM BT Enabler - PART 2 of 2 - Patch kern.hv_vmm_present=0` |

5. Save the configuration

6. Reboot your VM

For users who prefer to manually edit the configuration file:

1. Mount your EFI partition

2. Locate and open your `config.plist` file in a text editor

3. Find the `<key>Kernel</key>` → `<dict>` → `<key>Patch</key>` → `<array>` section

4. Add these two `<dict>` entries within the `<array>`:

<dict>

<key>Arch</key>

<string>x86_64</string>

<key>Base</key>

<string></string>

<key>Comment</key>

<string>Sonoma VM BT Enabler - PART 1 of 2 - Patch kern.hv_vmm_present=0</string>

5. Save the file

6. Reboot your VM

- The `MinKernel` values (`20.4.0` and `22.0.0`) may need adjustment depending on your specific macOS version (Monterey, Ventura, Sonoma, etc.)

- If you encounter issues, consult the [OpenCore documentation](https://dortania.github.io/docs/) for appropriate values for your setup

- Always back up your configuration before making changes

- After applying the patch and rebooting, try signing into Apple services again

This patch tricks macOS into believing it's running on physical hardware by redirecting the `hv_vmm_present` kernel variable, which normally indicates VM presence. After applying the patch, Apple services should function normally within your virtual environment.
