The main program - Mac Sequence View - is a drag and drop application that quickly generates a detailed, sortable quality report from your DNA chromatogram files. From the report, you can open and view the ABI files (DNA sequences). This suite also comes with sifter - a small application that allows you to sort out your DNA sequences based on quality criteria that you set.
