I want to know the answer to the following question:
When did Apple replace their CR with line feed (LF)?
All the background I'm provided with is that "The original Macintosh OS, Apple DOS, and ProDOS, on the other hand, used carriage return (CR) alone as a line terminator; however, since Apple replaced these operating systems with the Unix-based OS X operating system, they now use line feed (LF) as well.". Is that enough to answer the question?
