How to Format an External Drive for macOS

When it comes to using external drives with your Mac, formatting them correctly is crucial for smooth functionality and compatibility. In this article, we will guide you through the process of formatting a flash drive or external hard drive on your Mac.

Step 1: Open Disk Utility

To start, click on the magnifying glass icon in the top-right corner of your screen and type 'Disk Utility.' You can also use Spotlight Search to find it by pressing the 'Command' button and the 'Space' button together. Once you've opened Disk Utility, you'll see a list of available disks and volumes.

Step 2: Identify Your Device

Under the 'Format' section, you'll be able to see the format of your device. To get more information about the device, right-click on the device name and select 'Get Info.' Alternatively, navigate to the Finder directory and look for your device on the left-side menu.

Choosing a File System Format

There are two main file system formats available in Disk Utility: Journaled and Mac OS Extended (Case-sensitive, Journaled). Unless specifically required, we recommend using the 'Journaled' format as it is similar to the Mac format and protects the integrity of the hierarchical file system. This format is also highly compatible with multiple devices.

Understanding Different File System Formats

* Mac OS Extended (Journaled): This format uses the Mac format to protect the integrity of the hierarchical file system. It's recommended for devices used with MacBooks.

* Mac OS Extended (Case-sensitive, Journaled): This is similar to the Journaled format except that all folder names are case-sensitive. For example, a folder named 'MYFOLDER' is differentiated from a folder named 'myfolder.'

* ExFAT: This file system format is compatible with multiple devices, including PCs and gaming consoles. It's recommended for devices that will be used on both Windows and macOS platforms.
