# macinfo - Reconstructed Source Code

This is the reconstructed source code of the `macinfo` binary, decompiled and cleaned up for analysis purposes.

## Overview

`macinfo` is a command-line tool that interfaces with Apple's Find My Mac (FMM) infrastructure using private frameworks. It provides various commands for:

- **FMM Account Management**: Get, remove, and clear FMM accounts
- **Activation Lock Operations**: Check status, enable/disable, remove via various methods
- **T2 Bridge Communication**: Interact with T2 chip on supported Macs
- **Device Operations**: Obliterate (erase), clear embedded system, NVRAM operations
- **Lost Mode Operations**: Exit authentication, token management
- **Biometric Operations**: Disable biometric authentication

## Files

| File | Description |
|------|-------------|
| `main.m` | Entry point |
| `CLTool.h/m` | Base command-line tool class with argument parsing |
| `FMMClient.h/m` | Main FMM client with all commands |
| `EmbeddedOSSupport.h/m` | T2/biometric operations |
| `BridgeSupport.h/m` | T2 bridge communication |
| `Makefile` | Build configuration |

## Required Frameworks

### Public Frameworks
- Foundation
- IOKit
- LocalAuthentication
- CoreFoundation

### Private Frameworks (not publicly available)
- BiometricKit
- FMCore
- FMCoreLite
- FindMyDevice
- FindMyMac
- NearField
- RemoteServiceDiscovery
- RemoteXPC

## Building

This code **cannot be compiled** without access to Apple's private frameworks, which are not distributed outside of Apple.

```bash
make        # Will fail without private frameworks
make stub   # Attempts build, will have missing symbols
```

## Commands

Run `./macinfo` without arguments to see available commands:

```
Bridge Operations:
  testbridge          Test T2/bridge chip communication
  getbridgeaccount    Get bridge account info
  hassoc              Check for Secure Enclave
  bridgeids           Print bridge identifiers
  secureboot          Print secure boot status

FMM Account Operations:
  getaccount          Get FMM account (sync)
  getaccountasync     Get FMM account (async)
  removeaccount       Remove FMM account by username
  clearaccounts       Clear all FMM accounts
  hasaccount          Check if FMM account exists
  disablebadauth      Disable FMM with bad auth

Activation Lock Operations:
  alcapable           Check AL capability
  allocked            Check if Activation Locked
  enableal            Enable Activation Lock
  removeal-icloud     Remove AL via iCloud
  removeal-neem       Remove AL via Neem
  removeal-managed    Remove AL (MDM)

Device Operations:
  obliterate          Trigger device erase
  clearembedded       Clear embedded system
  nvram               Print NVRAM contents
  deleteguid          Delete FMM GUID
  prefs               Print FMM preferences
```

## Technical Notes

### FMDFMMManager
The main interface to FMM functionality. Methods are called via Objective-C runtime since the framework is private.

### T2 Bridge Communication
Uses `RemoteServiceDiscovery` and `RemoteXPC` to communicate with the T2 chip. The bridge device type is "bridge".

### Activation Lock
Multiple removal methods exist:
- **iCloud**: Standard user-initiated removal
- **Neem**: Apple's internal system (requires Apple credentials)
- **Managed**: For MDM-enrolled devices

### NVRAM Keys
FMM stores data in NVRAM under keys like:
- `fmm-mobileme-token-FMM`
- `fmm-computer-identifier`

## Disclaimer

This code is provided for **educational and analysis purposes only**. The original binary interacts with security-sensitive Apple systems. Unauthorized use of such tools may violate laws and Apple's terms of service.

## Original Binary Info

- **Type**: Mach-O Universal Binary (x86_64 + arm64e)
- **Encryption**: AES-256-CBC
- **Key**: `JHKloWYt2EpSYxYErmFD7naOYLa9QyrfioOCpZjFtCI=` (base64)
