Formatting your Mac hard drive happens because of a variety of reasons.

Whatever it is, knowing what works best for you is important. Here, we will introduce the best 5 disk formatters for Mac users to securely and conveniently format hard disk drives on Mac computers.
Part 1. How To Choose File Format for Mac?
The appropriate file format is necessary when formatting your Mac hard drive. File formats are the language of a computer's memory. Choosing a suitable file format is one important step in minimizing system problems.
Here are the most popular file types for Mac:
| File Format | Best For | Key Limits |
| APFS | Mac-only drives; latest macOS (High Sierra+) | Encryption supported; not readable by Windows without third-party tools |
| HFS+ | Older Macs (pre-High Sierra); external drives shared with Macs | Encryption supported; not readable by Windows |
| FAT32 | Cross-platform transfers (Mac + Windows + Linux) | No encryption; 4 GB max file size; more disk errors |
| exFAT | Cross-platform transfers with large files | No encryption; full read/write on Mac and Windows |
| NTFS | Windows-formatted drives read on Mac | Mac reads but cannot write natively |
1. APFS (Apple File System)
The latest file type from Apple arrived with macOS High Sierra, and is the right choice for users who only use Macs. It's efficient, reliable, and can encrypt files. If you're all-in on the latest and greatest from Apple – hardware and software – APFS is a good choice.
2. HFS+ (macOS extended)
HFS+ is the pioneer of APFS, and Macs running macOS prior to High Sierra will use it by default. HFS+ hard drives, like APFS, can be encrypted. It's a great format when working with your external hard drives on your Mac, and will work great with every other Mac user out there.
3. FAT32 (File Allocation Table32)
This file type is supported by Macs, Windows PCs, and Linux machines. FAT32 is the best option for frequently transferring files between operating systems. Remember that FAT32 cannot be encrypted and has no other security features. File sizes are also limited to 4GB, and FAT32 causes more disk errors than other file types.
4. exFAT (Extensible File Allocation Table)
This file type has all the same characteristics but has greater storage capabilities than FAT32. Mac can fully read and write external devices with the exFAT format.
5. NTFS (New Technology File System)
Apple macOS like Big Sur, Catalina, and even older operating systems can read Windows-formatted NTFS drives. In a word, you can open and view contents in an NTFS drive on Mac will not be able to write to NTFS files natively.
