Depending on your needs, you can choose the appropriate file system format for your storage drives. For example, if you’re using an external hard drive for Time Machine backups, you’ll want to format it as HFS+ or APFS to ensure compatibility with macOS. Alternatively, if you need to share files between your Mac and other devices, you may opt for the ExFAT file system, which offers cross-platform compatibility.
Disk Encryption
Disk Utility also provides the ability to encrypt your storage drives, ensuring the confidentiality and security of your data. By enabling disk encryption, you can protect your sensitive files and documents from unauthorized access, even if your device is lost or stolen.
The encryption feature in Disk Utility supports the industry-standard AES-256 encryption algorithm, providing a robust layer of protection for your data. Whether you’re encrypting your internal startup disk or an external storage drive, Disk Utility makes the process straightforward and user-friendly.
Storage Optimization
Maintaining optimal storage performance on your Mac is crucial for a seamless computing experience. Disk Utility offers several tools and techniques to help you optimize your storage and keep your system running at its best.
