Explanation: Everything About Mac Partitions

Mac partitions or volumes are designed to serve the same purposes as Windows partitions, including serving as a database for users to store and maintain data on their machines. Due to some common causes, such as hard drive failure, erratic system shutdown, virus attacks, power surges, corrupt software, corrupt file systems, or other errors, Mac computers may experience the same problem as Windows computers about these partitions becoming lost, deleted, formatted, or immoral.

Knowing the different partition kinds is crucial since you can choose the required format when you partition your Mac's hard disk. Mac partitions come in three different flavors:

  • APFS (Apple File System). The default file system for Macs runs on macOS 10.13 High Sierra or later. Compared to HFS+, it delivers faster speeds, more robust encryption, and better data handling. It is an excellent choice for SSDs and Macs with more recent macOS versions.
  • HFS+ (Hierarchical File System). HFS+ is prior to APFS. The older macOS versions use this file system (macOS 10.12 or earlier). If you wish to, you can still utilize it. When you have an older Mac that doesn't support APFS and a new Mac, it's a fantastic alternative for cross-compatibility or older Macs. But aside from that, using APFS is advised because it has many valuable features.
  • MS-DOS (FAT) and exFAT. Microsoft created these two file systems, and macOS supports them to be compatible with external storage devices with Windows file systems.

Step 4. You will be presented with the option of creating a new log file or not. The first option is advised because it will allow you to view all the tasks that the tool is completing, but you are free to make your own decision.
