Apple is increasing its support for APFS on its computing platforms, bringing the ability to use Time Machine with an APFS-formatted disk to macOS Big Sur, while enabling the ability to view external drives using encrypted APFS in iOS and iPadOS 14.
In this article, we are going to introduce the mac file system - APFS. What Is APFS Format. APFS, short for Apple File System, is a new file system released by Apple to replace the HFS+ file system currently in use. Mac minecraft jar. The core of the system is encryption, which will provide a unified encryption method for each device of Apple. Or use the following command to format Mac OS Extended to Mac OS Extended (Journaled): sudo mkfs.hfsplus -J /dev/sdaX /dev/sdaX is the partition you want to format. Convert to APFS. From the MacOS High Sierra version, Apple announced a new file system called APFS. By default, macOS High Sierra can only be installed on an APFS partition. I am experiencing an identical problem to the one in: Unable to format internal drive as APFS on 2018 MacBook Pro However this thread in unanswered and unresolved My internal drive can format to everything except APFS, I have tried troubleshooting via linux, and simple disk utility.
Introduced in 2016, APFS is Apple's forward-thinking file system that it uses across practically its entire device ecosystem. With the introduction of macOS Big Sur, iOS 14, and iPadOS 14, Apple will be making it even more useful for users, by adding support for APFS in a few new areas.
On macOS Big Sur, Apple is finally bringing the ability to use an APFS-formatted drive with Time Machine, 9to5Macreports. With macOS Catalina and earlier releases, users were able to back up to an HFS+-formatted disk but not an APFS-formatted version, with macOS offering to reformat the drive to HFS+.
Under Big Sur, users will be able to back up directly to an APFS-formatted drive, eliminating the need to reformat any disks.
For iOS 14 and iPadOS 14, Apple has plugged a hole for external drive support for one specific use case: APFS encrypted drives. While it is currently possible to view external drives in a number of common formats from an iPhone or iPad, it only works for non-encrypted drives, with encrypted drives being unreadable by the mobile devices.
On connecting an encrypted APFS drive to iOS 14 or iPadOS 14, the drive will appear on the updated Sidebar, with a selection of the drive bringing up a password prompt to decrypt it.
The added support for encrypted drives will only work for APFS-formatted drives, which may still be a limiting factor for some users in a multi-platform environment.

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), 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).
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.
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.
