JHFS+ refers to the Mac OS Extended Journaled format, which is proprietary to Apple and can only be used on macOS. VOLUME-NAME is the name you want to give to your pen drive. For this example, it will be “Untitled.” USB-LOCATION-AND-NAME is the name and location of your pen drive, which usually looks like “/dev/disk2” or “/dev. Set Format to Mac OS Extended (Journaled) Set Scheme to GUID Partition Map WARNING: Formatting the drive will erase all data on the drive, so you should copy any data you want off the drive prior to formatting. Click the Erase button, Disk Utility will start formatting the drive.

Disk Utility User Guide

Disk Utility on Mac supports several file system formats:

• Apple File System (APFS): The file system used by macOS 10.13 or later.

• Mac OS Extended: The file system used by macOS 10.12 or earlier.

• MS-DOS (FAT) and ExFAT: File systems that are compatible with Windows.

Apple File System (APFS)

Apple File System (APFS), the default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. While APFS is optimized for the Flash/SSD storage used in recent Mac computers, it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. macOS 10.13 or later supports APFS for both bootable and data volumes.

APFS allocates disk space within a container (partition) on demand. When a single APFS container has multiple volumes, the container’s free space is shared and is automatically allocated to any of the individual volumes as needed. If desired, you can specify reserve and quota sizes for each volume. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all the volumes in the container.

Choose one of the following APFS formats for Mac computers using macOS 10.13 or later.

• APFS: Uses the APFS format. Choose this option if you don’t need an encrypted or case-sensitive format.

• APFS (Encrypted): Uses the APFS format and encrypts the volume.

• APFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.

• APFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. For example, folders named “Homework” and “HOMEWORK” are two different folders.

You can easily add or delete volumes in APFS containers. Each volume within an APFS container can have its own APFS format—APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).

Mac OS Extended

Choose one of the following Mac OS Extended file system formats for compatibility with Mac computers using macOS 10.12 or earlier.

• Mac OS Extended (Journaled): Uses the Mac format (Journaled HFS Plus) to protect the integrity of the hierarchical file system. Choose this option if you don’t need an encrypted or case-sensitive format.

• Mac OS Extended (Journaled, Encrypted): Uses the Mac format, requires a password, and encrypts the partition.

• Mac OS Extended (Case-sensitive, Journaled): Uses the Mac format and is case-sensitive to folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.

• Mac OS Extended (Case-sensitive, Journaled, Encrypted): Uses the Mac format, is case-sensitive to folder names, requires a password, and encrypts the partition.

Windows-compatible formats

Choose one of the following Windows-compatible file system formats if you are formatting a disk to use with Windows.

• MS-DOS (FAT): Use for Windows volumes that are 32 GB or less.

• ExFAT: Use for Windows volumes that are over 32 GB.

Summary :

How much do you know about APFS vs Mac OS Extended? Which Mac file system should you choose? How to format hard drive for Mac? If you have similar questions on your mind, please read this page carefully to find answers; the main differences between APFS and Mac OS Extended file system and several ways to format a hard drive (internal/external) on Mac will be introduced.

Mac (formerly known as Macintosh) refers to the personal computers that are designed, manufactured, and sold by Apple Inc. MacOS is one of the most popular operating systems in the world; it’s the main competitor of Windows.

Common Mac file system includes:

• APFS (Apple File System): the default file system used in macOS 10.13 and later versions.
• Mac OS Extended: the file system used in macOS 10.12 and earlier versions.
• FAT (MS-DOS) and exFAT: the system systems that are supported by both Mac & Windows.

So you may ask what are the differences between APFS and Mac OS Extended, right? The following content first discusses on APFS vs Mac OS Extended; after that, it will tell you how to format a hard drive for Mac in several different ways.

Part 1: APFS vs Mac OS Extended

In this part, I’ll first introduce APFS and Mac OS extended to you. Then, I’ll compare these two file systems used on Mac for you in brief.

What Is APFS Format

Format Flash Drive Mac Os Extended Journaled

APFS (the full name is Apple File System) is a proprietary file system released by Apple Inc. It can be used on different devices running macOS High Sierra (10.13) and later, iOS 10.3 and later, all versions of iPadOS, watchOS 3.2 and later, or tvOS 10.2 and later. APFS is a new file system which was originally designed by Mac to fix core problems of Mac OS Extended.

What Is Mac OS Extended (Journaled)

Mac OS Extended, also known as HFS+, HFS Plus or HFS Extended, is actually a journaling file system released by Apple Inc. It was released in 1998 to replace HFS (Hierarchical File System, also known as Mac OS Standard or HFS Standard), which is the previous primary file system in Apple computers. Two main advantages of HFS+ when compare to HFS are: a. it gives support to much larger files; b. it uses Unicode for naming items.

Part 2: Which Is Better, APFS or Mac OS Extended

APFS vs HFS+ vs HFS:

APFS file system was announced in June 2016 to replace HFS+ (also known as HFS Plus or Mac OS Extended); the latter was used on all Mac computers as the primary file system since 1998 to replace the previous HFS.

Choose APFS for SSDs & Flash Storage Devices

When compared to Mac OS extended, APFS has been optimized a lot in terms of encryption, so it’s more suitable for flash and solid-state drive storage. APFS becomes the default file system for both for SSDs (Solid State Drives) and flash drives.

• In 2016, APFS was first released by Apple to replace Mac OS Extended (the previous default file system on Mac); it carries all sorts of benefits you can found in Mac OS Extended.
• A partial specification for APFS was published by Apple in September 2018 to allow the read-only access to APFS drive on even unencrypted and non-Fusion storage devices.

But don’t worry, you can still use the APFS on mechanical and hybrid drives.

To gain quality but free USB data recovery service, you should use MiniTool Power Data Recovery Free Edition; this post tells you how to recover USB data.

There are two main highlights in APFS.

1^st: fast speed. Copying and pasting a folder on APFS drive can be finished in an instant since the file system points to basically the same data twice.

• There are huge improvements in metadata so that many actions can be performed quickly; for example, confirming how much space the target file/folder takes up on an APFS drive.
• The reliability is also improved a lot. Users don't encounter corrupted files as often as they used to.

2^nd: reverse compatibility. If you are running 2016’s macOS Sierra or the later versions of macOS, congratulations, you have both read and write access to APFS, HFS +, and HFS file system. However, for users who run an older Mac (or a Windows operating system), they are not allowed to write to APFS-formatted drives.

Pros & Cons of APFS

Main advantages of APFS:

• It’s able to create point-in-time snapshots for users.
• APFS allows users to encrypt the full disk by using a single or multi-key so as to enhance the security.
• The checksums are used to ensure the integrity of metadata.
• It creates new records, instead of overwriting the existing ones, in order to avoid metadata corruption; the records may be corrupted because of system crash or other reasons.
• The storage management of APFS is more efficient than HFS+, resulting in helping users get additional free space.
• Users don't need to write changes twice by choosing APFS over HFS+; this will increase the system performance on some devices.
• The clones or multiple copies of the same file are allowed; it will only store the changes as deltas. This helps to reduce storage space greatly when users copy files, make revisions, or do other things.
• The APFS drive is generally more stable and reliable than the previous HFS+ or HFS drive.

Main disadvantages of APFS:

• Compression is not allowed on an APFS drive.
• It gives no support to the Fusion drives.
• The NVRAM (Non-volatile Random-access Memory) can’t be used even for data storage.
• The Checksums used are only available for ensuring integrity of metadata (that of user data can’t be guaranteed).
• You can only access the encrypted volumes from another other computer which runs macOS High Sierra.
• The biggest disadvantage of all seems to be: APFS isn’t compatible with Time Machine till now. That’s why users are told to make backups on Mac OS Extended drive unless they use a third-party backup tool rather than the built-in Time Machine.

Choose Mac OS Extended Journaled for Mechanical Hard Disks

Mac OS Extended (HFS+) is the default file system for all Macs from 1998 to 2017, until the new APFS replace it. Till now, it’s still the default file system for both mechanical and hybrid hard drives. You should keep it unchanged while you install the macOS or format external hard drive Mac. The HFS+ is a better choice than APFS on even current mechanical and hybrid hard drives.

Besides, you should definitely choose Mac OS Extended when you reformat external hard drive Mac considering that it may be used on older Macs running El Capitan or earlier versions of macOS. As you know, the new APFS file system is not compatible with these old macOS versions.

Pros & Cons of HFS+

Main advantages of HFS+:

• It gives support to the Fusion drives (which can’t be supported by APFS).
• It gives support to all versions of Mac OS X and macOS.
• You can encrypt volumes and then access them from any version of Mac OS X and macOS.

Main disadvantages of HFS+:

• There’s no point-in-time snapshot for users.
• The nanosecond standard is not used for Timestamps.
• The native file support for other file systems is too limited.
• The support to Mac OS Extended will be stopped on February 6, 2040.
• No checksum is used for metadata integrity or user data integrity.
• You can’t have concurrent access to the file system by a process.

Please ask yourself the following questions when you choose between APFS and Mac OS Extended:

• Are you formatting the internal disk or the external hard drive on your Mac?
• Which macOS are you running? Do you prepare to install macOS High Sierra or later?
• Is the Time Machine backup or bootable installer included in your daily schedule?
• Are you preparing to use the disk on another Mac or even Windows computer?

Bonus Tip: Choose exFAT for Hard Drives Used on Both Mac & Windows

Though the file system of main system drive on Mac is confined to APFS and Mac OS Extended, you can still consider exFAT (or the older FAT) when you format an external hard drive on Mac.

The most obvious benefit of using exFAT is that it can work with both Windows and macOS computers (you have both read and write access to the exFAT drive). Although there are solutions to read Mac formatted drive on Windows or read a Windows formatted drive on Mac, formatting drives to exFAT is still a convenient thing and an economical choice.
