If you are a Mac user and occasionally work on Windows, you will find that macOS offers a beautiful collection of fonts that are not available on Windows. Professional users like artists and web designers mostly switch between macOS and Windows for their work and appreciate how macOS renders fonts.

MacOS has a good collection of fonts that are nicer, smoother, easier, and optimized for reading than the ones available in Windows. But unfortunately, you cannot use the Mac font in Windows as both Windows and Mac use different font rendering technology. However, Windows font is of True Type format (.ttf) which is supported in Mac. But vice versa is not true.
The Mac font is of .dfont type and Windows cannot directly read Mac True Type fonts like .dfonts. Windows can only read Windows Open Type and Windows TrueType fonts. To copy Mac font (.dfont) to Windows and use them in Windows, you have to use a third-party application to convert Mac fonts (.dfont) into Windows TrueType format(.ttf).
