Finding Character Return in a string on the MAC

I have code that looks for a character return in a string and returns the position. This code works with Notes on Windows, but not on the Mac

Line of code that isn’t working on the MAC

pos = InStr(SearchReturn, Chr$(13))

In windows it returns the position of the character return, on the Mac it returns a 0, so obviously it’s not recognizing chr$(13) as a character return.

Thanks in advance
