# setUser(_:)

Sets the font used by default for documents and other text under the user’s control to the specified font.

```
class func setUser(_ font: NSFont?)
```

## Discussion

Specifying `aFont` as `nil` causes the default to be removed from the application domain.

## See Also

[`+  userFontOfSize:`](/documentation/AppKit/NSFont/userFont(ofSize:))
