View .ps and .eps files on Mac
Use a third-party app that supports PostScript and Encapsulated PostScript files.
macOS no longer includes built-in support for viewing PostScript (.ps) and Encapsulated PostScript (.eps) files. Apps that support these files are available from other developers on the App Store and elsewhere.
If your printer supports PostScript, you can continue to print .ps and .eps files by dragging them into your printer queue: Select your printer in Printers & Scanners settings, click the Printer Queue button, then drag the file into the printer queue window to print it.
Some earlier versions of macOS include limited built-in support for .ps and .eps files. For example, in macOS Monterey or earlier, you can use the included Preview app to view and print these files.
