We'll outline the four file formats supported on Mac and recommend the best for you based on different situations. Then, we'll discuss how to format a hard drive on a Macintosh using Disk Utility.
What Is the Best Format for a Mac Hard Drive?
To choose the best file format for your Mac hard drive, you need to know the options available in Disk Utility. This utility supports four Macintosh hard drive formats, which are the primary choices for formatting a Mac hard drive. These formats are used to prepare the drive for use and ensure compatibility with your Mac's operating system.
Let's look at how the four file systems work.
Apple File System (APFS)
APFS primarily supports Mac computers running macOS 10.13 or later, with features like improved file system fundamentals, space sharing, snapshots, fast directory sizing, and strong encryption, and is also compatible with external Flash and SSD storage.
APFS is an "intelligent" file system format that allocates disk space based on demand, ensuring volumes or partitions don't run out of space. It also allows reserving disk space for each volume and is further broken down into different formats.
- APFS
- APFS (encrypted)
- APFS (case-sensitive)
- APFS (case-sensitive, encrypted)
Mac OS Extended (HFS+)
Apple's Mac OS Extended (HFS+) was developed as a journaling file system, primarily for use with Mac OS X until APFS was introduced. It supports macOS 10.12 or earlier.
Mac OS Extended supports the following file formats:
- Mac OS Extended (Journaled)
- Mac OS Extended (Journaled, Encrypted)
- Mac OS Extended (Case-sensitive, Journaled)
- Mac OS Extended (Case-sensitive, Journaled, Encrypted)
MS-DOS (FAT)
The FAT file system is compatible with both Windows and Mac operating systems, and supports file volumes of less than 32GB, including internal and external hard drives.
exFAT
exFAT is an improved version of the FAT file system, compatible with both Mac and Windows operating systems. It allows for volumes larger than 32GB, making it a suitable choice for external hard drives on Mac devices, where it offers better compatibility than other file systems. For more information, you can visit this page on "ExFAT VS MacOS Extended".
The best file system on a Mac depends on the specific scenario, as each has its own strengths. APFS is ideal for modern Macs, offering better performance and security, while HFS+ is still compatible with older Macs and some external drives. The newer APFS is also recommended for external drives, especially those with large storage capacities. However, if you need to share files with Windows users, HFS+ is still the best option due to its compatibility with Windows.
| File | Recommendation |
|---|---|
| APFS | The best operating system for flash drives and SSDs is macOS 10.13 or later, which provides optimal performance and compatibility. |
| Mac OS Extended | The recommended system is suitable for mechanical drives and other drives that support macOS 10.12 or earlier. |
| MS-DOS (FAT) | For external hard drives shared between Mac and Windows devices, the volume size should not exceed 32GB. |
| exFAT | The best external drives for shared use between Mac and Windows computers are those that are compatible with both operating systems. These drives typically have a USB interface and are formatted with a file system that is readable by both Mac and Windows, such as exFAT. |
