With an external hard drive, you can efficiently transfer large files between computers running the same operating system type. However, it could be a totally different story if you plan to do this between a Mac and a PC. That's because, the two platforms have their specific file systems by default: Windows uses NTFS, while Mac use HFS+ or APFS. Out of the box, Windows can't read or write to HFS+/APFS and Macs can't write to NTFS drives.
Though the default file system is really a hurdle to use one external hard drive between Windows and Mac, there're still file systems that can connect the two worlds, i.e. FAT32 and exFAT. Thus, in order to use the same external hard drive on both Macs and PCs, you can format your external hard drive and make it compatible with both macOS and Windows OS.
But before that, it will be helpful if you know some background information and do some preparations.

Understand common file systems
Whether you're transferring files between Windows and Mac using external hard drives, or other portable storage devices like USB flash drives or SD cards, you'll be told about 3 file systems: FAT32, exFAT and NTFS. But do you know what is the difference between them?
You could use an external hard drive for Mac, such as Seagate Backup Plus drives for Mac and WD my passport for Mac to back up your files, but do you know what makes a hard drive exclusive for Mac is not the disk itself but the file system of this disk?
To answer the questions above and broaden your mind, this part will have a brief introduction to some common file systems.
FAT32
Pros: It can universally work with all versions of Mac, Windows, Linux, game devices, as well as other devices supporting a USB port.
Cons: FAT32 comes with file size limits and drive partition limits. It doesn't support files larger than 4GB, drive partition larger than 32GB on Windows, or drive partition larger than 2TB on macOS.
So FAT32 is commonly used in floppy disks, SD memory cards, USB flash drives as well as many portable and embedded devices. Also, FAT is the standard file system for digital cameras.
exFAT
Pros: The largest partition and file sizes it supported are nearly unlimited by today's standards.
Cons: exFAT file system is not compatible with older operating systems. It should be used in macOS 10.6.5 or newer, and PC need to be Windows Vista SP1, Windows 7 or newer.
As most users have upgraded operating system, it is actually quite easy to meet to lowest operating system requirements of exFAT. So exFAT can be a very good option to share external hard drive between macOS and Windows. Similarly, it also optimized for flash memory drives such as USB flash drives and SD cards. It can be easily implemented in firmware that has low memory and low power requirements, such as cameras, mobile phones, media players, etc.
NTFS
Pros: It is an improvement for FAT32, and it is used as the default file system of Windows system hard drive due to its improved performance, reliability, and disk space use.
Cons: You can't write to NTFS drives in macOS and the disabled-by-default write support for NTFS in macOS is unstable.
Mac OS Extended (HFS+)
Pros: It is the primary file system of Apple computers with the 1998 release of Mac OS 8.1. It also frequently used as Time Machine backup external hard drives of WD, Seagate, etc.
Cons: If HFS+ format volume is connected to a computer running Mac OS 8.0 or earlier, the files will not be visible or accessible.
APFS
Pros: The proprietary file system for macOS High Sierra (10.13), macOS Mojave (10.14), and macOS Catalina (10.15). It is optimized for flash drives and SSD with a primary focus on encryption.
Cons: Because APFS has no support for hard links to directories while Time Machine still relies on them, APFS is not yet a good option for backup volumes for Mac.
