# NSLayoutManager.TypesetterBehavior.latestBehavior

The current typesetter behavior in the current operating system.

## Declaration

```swift
case latestBehavior
```

## Discussion

Discussion For OS X v10.2, this behavior is identical to NSTypesetterBehavior_10_2. If you use this behavior setting, you cannot necessarily rely on line width and height metrics remaining the same across different versions of macOS.
