For macOS 10.10 and later only. This script will change the file type of the selected AAC tracks to "M4B " and file extension to ".m4b", thus making them bookmarkable. (That is, the track will natively resume playing wherever you left off the last time you played it.) Deletes and re-adds each track so it will appear in the Audiobooks Library. Ratings, play count, last played date, skip count, and skipped date are preserved.
