External drives can serve as a valuable tool for expanding your Mac’s storage capacity, as well as for transferring and backing up files. However, before you can start using an external drive with your Mac, you need to format it properly. Choosing the right file system and partition scheme can ensure compatibility and performance. Here, we explore the best ways to format external drives for Mac.
1. Mac OS Extended (Journaled): This format is the default option for Macs, and it provides the best compatibility and performance. Mac OS Extended (Journaled) supports file sizes up to 8 exabytes and is suitable for both regular use and Time Machine backups.
2. APFS: The Apple File System (APFS) is the newest file system developed by Apple. It offers enhanced performance, improved security, and better space management compared to Mac OS Extended (Journaled). APFS is recommended for solid-state drives (SSDs), but it is also compatible with traditional hard disk drives (HDDs).
3. ExFAT: If you need to use the external drive with both Mac and Windows computers, formatting it with the ExFAT file system is the best option. ExFAT supports large file sizes and is compatible with both operating systems. However, keep in mind that ExFAT may not offer the same level of performance or compatibility with Mac-specific features as the other options.
Before formatting an external drive, remember to back up any important data, as the formatting process will erase all existing files on the drive. Additionally, consider the intended use of the drive and the compatibility requirements with other devices when choosing the format.
The Importance of Formatting External Drives
Formatting external drives for your Mac is an essential step that should not be overlooked. By formatting the drive correctly, you can ensure its compatibility with your Mac and optimize its performance. There are several reasons why formatting external drives is important.
1. Compatibility with Mac
Formatting the external drive in a Mac-compatible file system, such as Mac OS Extended (Journaled) or APFS, ensures that the drive can be recognized and accessed by your Mac without any issues. This allows you to seamlessly transfer files between your Mac and the external drive.
2. Optimal Performance
Formatting the external drive optimizes its performance by organizing the data in a way that is efficient for your Mac. It helps prevent fragmentation and ensures faster read and write speeds. This is especially important if you plan to use the external drive for tasks that require high-speed data transfer, such as video editing or running applications directly from the drive.
3. Data Security
Formatting the external drive allows you to securely erase any existing data on the drive. This is particularly important if you plan to sell or dispose of the drive, as it ensures that your sensitive information cannot be easily recovered. By properly formatting the drive, you can protect your personal data and prevent potential data breaches.
In conclusion, formatting external drives for your Mac is crucial for compatibility, performance, and data security. By taking the time to format your drives correctly, you can ensure a seamless connection between your Mac and the external drive, optimize its performance, and protect your personal data.
Choosing the Right File System
When formatting an external drive for use with a Mac, it is important to choose the right file system. The file system determines how data is stored and organized on the drive, and it can affect compatibility, performance, and data security.
There are three main file systems to consider when formatting an external drive for a Mac: HFS+, APFS, and exFAT.
HFS+ (Hierarchical File System Plus) is the default file system used by Mac computers. It is compatible with older versions of macOS and offers good performance and data security. However, it has some limitations, such as a maximum file size of 2TB and a maximum volume size of 8EB.
APFS (Apple File System) is the newer file system introduced with macOS High Sierra. It is optimized for solid-state drives (SSDs) and offers improved performance, security, and reliability compared to HFS+. APFS also supports features like snapshots, which allow you to easily restore a previous version of a file. However, APFS is not compatible with older versions of macOS.
exFAT (Extended File Allocation Table) is a file system that is compatible with both Mac and Windows systems. It has no file or volume size limitations and is a good choice if you need to share the drive between Mac and Windows computers. However, exFAT does not support some macOS features like Time Machine backups, and it may not offer the same level of performance and data security as HFS+ or APFS.
When choosing the right file system for your external drive, consider your specific needs and requirements. If compatibility with older versions of macOS is important, HFS+ is a good choice. If you are using a newer version of macOS and want improved performance and features like snapshots, APFS is recommended. If you need cross-platform compatibility, exFAT is the way to go.
Remember that formatting an external drive will erase all existing data, so be sure to back up any important files before proceeding.
In conclusion, choosing the right file system is crucial when formatting an external drive for use with a Mac. Consider the compatibility, performance, and features offered by HFS+, APFS, and exFAT, and select the file system that best suits your needs.
Step-by-Step Guide to Formatting External Drives on Mac
Formatting an external drive on a Mac is a straightforward process that can be done in just a few simple steps. Whether you want to erase an old drive, reformat it for a different file system, or prepare it for use with Time Machine, this step-by-step guide will walk you through the process.
- Connect the external drive to your Mac using a USB or Thunderbolt cable.

- Mac OS Extended (Journaled): This is the default format for Mac drives and is compatible with both macOS and older versions of Mac OS X.
- APFS (Apple File System): This is the recommended format for modern Macs running macOS High Sierra or later.
- exFAT: This format is compatible with both Mac and Windows systems, making it a good choice if you plan to use the drive with multiple operating systems.
That’s it! Your external drive is now formatted and ready to use. Whether you need to store files, create backups, or use it as a bootable drive, you can now start using it with your Mac.
Remember, formatting an external drive will erase all data on the drive, so make sure to back up any important files beforehand. Additionally, different formats have different limitations and compatibility, so choose the format that best suits your needs.
What are the best external drive formats for Mac?
The best external drive formats for Mac are HFS+ and APFS. HFS+ is the older format and is compatible with older Mac operating systems, while APFS is the newer format and offers better performance and compatibility with newer macOS versions.
Can I use NTFS formatted drives on Mac?
Yes, you can use NTFS formatted drives on Mac, but for read-only access. By default, Mac can read NTFS drives but cannot write to them. If you want to have read and write access to NTFS drives, you can install third-party software like Paragon NTFS for Mac.
Should I choose FAT32 or exFAT for my external drive on Mac?
If you need to use your external drive on both Mac and Windows computers, it is recommended to choose exFAT. FAT32 has limitations on file size and is not suitable for larger files. ExFAT does not have these limitations and provides better compatibility between Mac and Windows.
What is the process of formatting an external drive on Mac?
