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

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 on demand. The disk’s free space is shared and can be allocated to any of the individual volumes in the container 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.
- 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.

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.
- 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.

Are you bored of opening your photos in the default Preview application on Mac ? Got a new photo viewer and want to make it as a default one on your Mac OS X ? Here is the simple tutorial to change the default application for specific file types on your Mac. Normally we use “Open With” option to open a particular file with a different application from the default ones. But next time when you open the same file it will open in the default application.

In order to completely change the default application for that specific file type follow the steps below.
Step 1: Choose a file that’s the type you want to change. For instance I have selected a JPEG file which uses “Preview” application on Mac OS by default. So I’m going to change the default application for JPEG files from “Preview” to “Skitch“, a simple image editor from Evernote. The first step is right click on that image file and select “Get Info” from that list.
Step 2: Once you did that you will get another window as shown in the screenshot below. In that you have an option called “Open With“. Below that there will be a drop down box, just click that. After you click that you will get a list of applications installed on your Mac which supports that particular file type.
Step 3: Choose the application from the list you want to set as a default one for that particular file type. In this case I’m gonna select “Skitch” as the default application to JPEG files. If you stop with this that particular file alone will open in Skitch. To view all files of that type in Skitch you have to choose one more option on that dialog box.
Step 4: Close that dialog box and click on “Change All” button below. A window will pop up as shown in the screenshot below. Click “continue” to confirm that all the JPEG files on your Mac will use Skitch as its default application. That is all, now the default application will be changed from “Preview” to “Skitch”.
