The following option descriptions apply to all verbs: In it, and then copies the specified files to the new filesystem. Hand, create -srcfolder creates a disk image container, puts a filesystem Only disk image have not changed since it was created. For example, verify verifies that the blocks stored in a read. The disk image device or to the (often file-oriented) content of the If any file structuresĪre understood, the associated volumes will mount and appear in theĪlways consider whether a "disk image" operation applies to the blocks of The new device for recognized file structures. Then, the kernel and Disk Arbitration probe First, the image is "attached" to the system The terms "attach" and "detach" are used to distinguish the way disk images are connected to and disconnected from the system.įor example, when you double-click a disk image in the macOS Finder, Many uses of disk images blur the distinctionīetween the disk image container and its content, but this distinction isĬritical to understanding disk images. Plugins, udifrez, udifderez, internet-enable, resize, segment,ĭisk images are containers that emulate disks. The rest of the verbs are currently: help, info, checksum, chpass,Įrasekeys, unflatten, flatten, imageinfo, isencrypted, mountvol, unmount, Verbs include attach, detach, verify, create, convert, compact, and burn. Hdiutil uses the DiskImages framework to manipulate disk images. Each volume within an APFS container can have its own APFS format-APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).Manipulate disk images (attach, verify, burn, etc). You can easily add or delete volumes in APFS containers. For example, folders named “Homework” and “HOMEWORK” are two different folders. For example, folders named “Homework” and “HOMEWORK” are two different folders.ĪPFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. Choose this option if you don’t need an encrypted or case-sensitive format.ĪPFS (Encrypted): Uses the APFS format and encrypts the volume.ĪPFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. LINUX MAC OS SPARSE ENCRYPTED FILESYSTEM FOR MACEach 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.Ĭhoose one of the following APFS formats for Mac computers using macOS 10.13 or later.ĪPFS: Uses the APFS format. If desired, you can specify reserve and quota sizes for each volume. LINUX MAC OS SPARSE ENCRYPTED FILESYSTEM FREEWhen 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. macOS 10.13 or later supports APFS for both bootable and data volumes.ĪPFS allocates disk space within a container (partition) on demand. 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. 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.
