Macintosh computers have always been fast and powerful. And, after the MacOS Catalina introduction, they have become even more rigorous.
If you have also updated your computer to Mac Catalina operating software and want to connect external hard drives with it, first get to know all the file formats supported by Mac Catalina.
Apple has allowed macOS to work with only certain file formats. If the external drive isn't formatted in Mac-compatible formats, it can create several errors like read-only, unable to mount USB drive properly, and so on.
This guide is compiled to help Mac Catalina users to find the best external hard drive file formats. Also, the post will throw light on how to format external hard drives into Mac compatible file systems.
Let's get started!
Mac Catalina supports plenty of different file formats. Depending upon the requirements, one can format a Mac external hard drive to the following file formats:
APFS is Apple's native file system that was introduced around 2017. It is a high-quality file system that includes copy-on-write metadata, increased encryption, improved data safety, and many other features.
If comfort and speed are your top attributes, APFS formatted external hard drives are perfect for you. On macOS Big Sur or higher, Apple allows users to choose APFS for Time Machine. But unfortunately, on Mac Catalina, Time Machine won't recognize the APFS external disk.
Hierarchical File System Plus, also known as Mac OS Extended, has been the main Mac storage system since 1998. In 2017, it was replaced with APFS. But it is still one of the best formats for external hard drives on Mac Catalina.
For older Macs (before 2016), HFS+ is the perfect file format to access external hard drives. Though, HFS+ and APFS both can't be formatted to Windows without third-party apps.
This file format was developed by Microsoft to offer simple compatibility with FAT32. It is a preferred file format for external hard drives that users can share between Mac and Windows.
Both Windows and Mac provide read-write support for exFAT, but it doesn't support journaling.
MS-DOS (FAT) is also a multi-purpose file system that can work perfectly with old mac computers. FAT offers great support to external drives for transferring heavy programs, including games.
NTFS is a proprietary journaling file system by Microsoft. It has numerous advantages over APFS and FAT file formats, such as improved performance, metadata structure, reliability, and disk space.
But unfortunately, NTFS external drives just get read-only support on Mac Catalina. The third-party software or adjustments with Terminal commands is required to be made to get read-write NTFS on Mac.
To better understand Mac Catalina compatible external drive formats, have a look at this table:
