Why Partition?

Organizing files, installing Windows, or simply improving data management are all excellent reasons to partition your Mac's hard drive. This guide provides a step-by-step approach.

Partitioning Methods:

Several methods exist for partitioning your Mac:

Method	Description
Disk Utility	The built-in macOS tool for disk management. Use Disk Drill for data recovery if needed.
Boot Camp Assistant	Ideal for installing Windows. Back up your data beforehand using Get Backup Pro.
Switching OS (Windows to macOS)	Use the Boot Camp icon in the Windows system tray.
Switching OS (macOS to Windows)	Use Startup Disk in macOS Utilities.
Choosing OS at Startup	Press Control Command Power, hold Option, and select your OS.
Partitioning External Hard Drives	Use Disk Utility; remember ExFAT for cross-platform compatibility (4GB file size limit).

Before partitioning, safeguard your data with Get Backup Pro (available on Setapp).

Partitions vs. Volumes:

• Partition: A physical division of your hard drive.
• Volume: A storage space macOS recognizes as a single unit (created from partitions).

Volumes are user-friendly; partitions are behind-the-scenes organizational tools.
