The biggest feature of this kind of file system is that it will record the whole write-in movement of disc so that it is convenient to trace back if it is in need. At the same time MiniTool Partition Wizard can help the ext2 and ext3 to manage the partition file system. Because that informations write-in includes many details such as changing the head information of files, searching for the writable space of disc, writing in the information sector one by one, etc, if any detail is interrupted half way, it will cause the inconformity of file system. Nevertheless, in the journal system, if the process is interrupted, the system can trace back and reform the interrupted part. There is no need to spend the time to examnine other parts. The speed of reformation is rather fast.
Features
1. High Applicability
If the system uses ext3 file system, even after the improper shut down, it needn't examination of file system. After the downtime of system, it only need a few ten seconds to recovery.
2. Integrity of Data
Ext3 file system can promote the integrity of file system to a large extent. It avoids the damage of accidental downtime. To keep the integrity of data, ext3 file system has two modes for you to choose. One is 'keep the consistency of file system and data' mode. Choosing this mode you will never find the junk files after improper shutdown.
3. The Speed of File System
Although when you are using ext3 file system, it needs to repeatedly write in when saving data, but in general ext3 is better than ext2. That is because the journal function of ext3 has optimized the read-write head of disc driver. Therefore read-write performance of file system has not dropped.
4. Data Conversion
Ext2 file system can be easily converted to ext3 file system. It only needs two simple orders to complete the conversion. The users need no time to back up, recover, and format the partition. Use the small tool tune2fs provided by ext3file system, it can easily convert ext2 file system to ext3 journal file system. In addition, ext3 file system can be directly loaded to convert to ext2 file system without any changes.
5. Multi-journal Modes
Ext3 has various journal modes. One working mode is to record all the file data and metadata (the data of definition file system data, the data of data) (data=journal mode.). Another working mode is to record the metadata, and not to record data. That is data=ordered or data=writeback mode. The system manager can choose between the speed or the consistency of file data according to the practical work requirement of system.

- The primary filesystem format in OS X is Apple's HFS Plus (or Mac OS X Extended), which is the default used for any newly formatted disk. And then selecting the Ext2/Ext3 partition and getting.
- Jul 07, 2019 If you work with Linux, you probably have a hard drive or two formatted with Ext4 or a related filesystem. Assuming you only work with Linux, that isn’t a problem. When you need to access data from that Ext4 filesystem on another operating system, you start to run into trouble. Macs, for example, don’t support Ext4 filesystems.

Once you have both OSXFUSE and FUSE-EXT2 installed you can mount the ext2/ext3/ext4 partitions as mentioned in other answers: Find the device name for the EXT partition you want to mount (e.g. Disk0s2 in the example below, (UPDATE) in later MacOS versions ext3/ext4 partitions might be labelled Microsoft Basic Data and not Linux).
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. Digital anarchy flickr free crack.
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
