Check disk partition scheme macOS)

macOS 使用 APFS（Apple File System）作为默认磁盘分区方案，系统盘通常包含多个卷，如“Macintosh HD”承载系统文件、“Macintosh HD - Data”存储用户数据，以及 Preboot、Recovery 和 VM 等辅助卷，APFS 支持空间共享和快照功能，使分区管理更灵活，用户可通过“磁盘工具”查看和调整分区，但修改系统分区存在风险，建议操作前备份数据。

Here's a comprehensive guide for MacBook Pro with UEFI/GPT:

MacBook Pro UEFI & GPT Overview

Boot System

• Modern MacBooks use UEFI (Unified Extensible Firmware Interface) instead of traditional BIOS
• Drives are typically formatted with GPT (GUID Partition Table) instead of MBR
• This is essential for macOS, Windows dual-boot, and Linux installations

Common Scenarios & Solutions

Installing Windows on MacBook Pro (Boot Camp)

Steps:
1. Open Boot Camp Assistant (in macOS)
2. Download Windows Support Software
3. Partition drive (creates GPT partition)
4. Install Windows in UEFI mode
5. Install Boot Camp drivers

Installing Linux alongside macOS

Requirements:
- Disable SIP (System Integrity Protection)
- Use rEFInd or GRUB bootloader
- Create EFI partition (200-500 MB)
- Format partitions with GPT scheme

Fix UEFI/GPT Issues

# Verify GPT
sudo gpt -r show /dev/disk0
# Repair GPT
sudo gpt recover /dev/disk0
# Check EFI partition
diskutil info disk0s1

Partition Scheme for Dual/Triple Boot

/dev/disk0 (GPT)
├── EFI System Partition (200 MB - FAT32)
├── macOS (APFS or HFS+)
├── Windows (NTFS)
├── Linux (ext4)
└── Swap (Linux swap)

UEFI Boot Commands & Shortcuts

Action	Shortcut
Boot Manager	Hold Option/Alt at startup
Recovery Mode	Cmd + R
Internet Recovery	Cmd + Option + R
Reset NVRAM	Cmd + Option + P + R
Safe Mode	Shift
Target Disk Mode	T
Apple Diagnostics	D

Troubleshooting Common Issues

"No Bootable Device" Error

# In Recovery Mode Terminal:
diskutil list
diskutil repairDisk /dev/disk0
# Reinstall bootloader
bless --mount /Volumes/Macintosh\ HD --setBoot

Windows Won't Boot After macOS Update

Boot into macOS Recovery
2. Select "Startup Disk"
3. Choose Windows partition
4. Restart

Convert MBR to GPT (Data Loss Warning)

# Using gdisk (install via Homebrew)
brew install gdisk
sudo gdisk /dev/disk0
# Convert: w (write GPT)

Best Practices

1. Always backup before partition changes
2. Keep EFI partition intact (don't delete)
3. Use GPT for drives >2TB
4. Disable FileVault before major changes
5. Keep firmware updated

Useful Terminal Commands

# List all disks
diskutil list
# Get detailed UEFI info
nvram -p
# Check boot mode
sysctl -a | grep EFI
# Set startup disk
systemsetup -setstartupdisk /Volumes/NAME
# Reset NVRAM from Terminal
nvram -c

Notes for Specific Models

• 2016+ MacBook Pro: T1/T2 chip adds security features

  • Enable "Allow booting from external media" in Recovery
  • Use "Startup Security Utility" for boot options

• 2015 and earlier: Standard UEFI implementation

  Full compatibility with standard UEFI tools
