I can't open .eps files on my mac.

Your tag line says that you are running macOS 14.8 (Sonoma) – and itt looks as though Apple removed all support for .eps files from Preview starting in macOS 13 (Ventura). Possibly in macOS 12 (Monterey) if the replies which I saw in Cannot view eps files anymore - Apple Community are correct.

Why has Apple been removing support for PostScript and Encapsulated Postscript? PostScript is a full-blown programming language – which means that you could theoretically write malware in it. (Microsoft also dropped support for inserting EPS images into Office/365 documents some time ago, for the same security reasons.)

It is a shame that this happened. PostScript is one of the things (together with the Mac Plus, the LaserWriter, and Aldus Pagemaker) that started the desktop publishing revolution. Both the Mac and PostScript can trace back their inspiration to the work done at Xerox PARC in the 1970s.

This was a widely used extension by many apps, so you'd first have to know what app made them. Such as, a Quark XPress EPS will not open in Photoshop.

Or, are you saying you can't access the DVD at all? If it's a really old disk written in the original HFS format - before HFS+ - then no, you can't open such a disk in any version of macOS after Mojave.
