If you are a computer nerd with a Mac and a Windows PC, you will discover that the two platforms use separate file systems, namely APFS/HFS for Macs and NTFS for Windows PCs. An external hard drive with a file system compatible with Windows and macOS is the only option if you want to use it with both platforms. The easiest method to accomplish this is to format the external hard drive you plan to use.

Windows PCs and Macs are compatible with both FAT32 and exFAT. However, exFAT supports files as large as 16EB, while FAT32's limit is 4GB. As a result, many people choose to format their external hard drive in exFAT rather than FAT32 so that it may be used with both Macs and PCs.
