Hi All,
- Mac OS Extended (Journaled) เป็นฟอร์แมตมาตรฐานสำหรับการลง macOS (ถ้าจะลง macOS ให้เลือกฟอร์แมตนี้). เกิน 4GB ได้ FAT จึงเหมาะกับการเป็นฟอร์แมตของ Flash Drive.
- Mac OS Extended (Journaled) or HFS Plus is a file system developed by Apple Inc. With the release of the Mac OS X 10.2.2 update on November 11, 2002, Apple added optional journaling features to HFS Plus for improved data reliability. The formatting decides the way the files are stored on your hard disk.
Mac OS Extended (or HFS+) is still a good option for older drives, but only if you plan on using it with a Mac or for Time Machine backups. If you need a cross-platform option, consider using ExFAT for your drive instead—both Windows and macOS can read these drives without any additional software. To use HFSExplorer, connect your Mac-formatted drive to your Windows PC and launch HFSExplorer. Click the “File” menu and select “Load File System From Device.” It will automatically locate the connected drive, and you can load it. You’ll see the contents of the HFS+ drive in the graphical window. 2 OS X Extended (Journaled) & OS X Extended (Case-sensitive, Journaled) This is the default file system for macOS 10.12 and earlier. It doesn't put a limit on the size of files you can save on the drive, and that's the greatest advantage. Windows-running computers can read the files formatted to OS X Extended (Journaled), but can't write to them.
I am new to Mac and the format of the OS on my new retina MBP says Mac OS Extended (Journaled, Encrypted). Please can you let me know what this exactly means?
I recently enabled FileVault encryption which completed with the below results

Has the format changed to Extended (Journaled, Encrypted) post this operation or is this the default OS format that ships with all Mac Books?
Also, I had customised this with 512GB Flash Storage but the info only shows 500. Is this normal and the difference (from what's actually stated) common across all capacities or only with 512? Please let me know.

Thanks in advance.

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.
