macOS Ventura Preview drops support for PostScript files
Following the release of the macOS Ventura software update on October 24, 2022, Apple announced in a new support document that its Preview application no longer supports vector files saved in the PostScript file format.
If your Mac is running macOS Ventura 13.0 or later (verify by choosing About This Mac from the Apple menu), you won’t be able to open PostScript (.ps) and Encapsulated PostScript (.eps) files in Preview mode. viewing. Deletion occurs at the system level.
For example, you also cannot preview a PostScript file by selecting it in the Finder and pressing the space bar. And since Preview doesn’t support plugins, don’t wait for third parties to add the missing PostScript support.

Why did Apple do it?
Apple hasn’t said why it removed PostScript support from the Preview app and the rest of macOS Ventura, but we can make educated guesses. On the technical side, Apple chips can certainly handle the vector file format of the 1980s.
This seems like a security measure because PostScript files can include inline scripts, which opens up a potentially dangerous new attack vector. For the same reasons, Microsoft removed PostScript support from its Office suite in 2018.
History of PostScript and why it is no longer relevant
Although PostScript is the first major vector file format and one of the oldest formats for storing images, PDF is now preferred by service bureaus.
However, PostScript was all the rage a few decades earlier. Photoshop manufacturer Adobe developed the PostScript format in the 1980s. Conceived as a page description language, it was quickly adopted by the nascent electronic publishing industry.
Converting text and graphics to hard copies proved to be a major advantage of PostScript. Since PostScript is a mathematical model for drawing objects, elements such as fonts and vector illustrations do not look blurry when magnified.
Sign in to desktop publishing
When PostScript shipped with the first Apple printers, suddenly anyone with a Mac and a LaserWriter printer could create and print professional-looking documents. This is how desktop publishing was born.
The use of PostScript has declined dramatically over the past two decades because the ubiquitous PDF file format has slowly but surely become the new PostScript.
This is recognized even by Adobe itself, the creator of PostScript. “Now that direct-to-the-web publishing has overtaken print for all but the most specialized publications, the PostScript file format is no longer as popular as it used to be,” says the Adobe website.
