The issue occurs when the file support system of the storage device on Windows is not supported by the Mac. The solution to this obstacle is converting the drive to the file format that is supported by both the operating systems. FAT32 is one of those file support systems, which works well in both macOS and Windows 10. In this article, we will find how to format and convert a Hard Disk Drive to FAT32.
