There are many CUE Splitters available online, however, most of them are only compatible with Windows. Usually, Mac users can't find a way to split CUE associated MP3, APE, WAV, FLAC, etc. What's more, most of CUE Splitters support splitting only one or two kinds rather than almost all common audio files with CUE sheet.
To split files with CUE, personally recommend you a powerful tool named Faasoft CUE Splitter.
It's easy and helpful
