How to open .PS files on Mac
To open .PS files on Mac, if your default apps won’t open the .PS file, use a Ghostscript-based tool to render or convert it to PDF.
Step-by-step instructions
- If your default apps won’t open the .PS file, use a Ghostscript-based tool to render or convert it to PDF.
- After conversion, open the PDF in your usual viewer.
Common issues
The .PS file won’t open or shows blank/garbled pages
This often happens when there’s no PostScript interpreter installed, the viewer lacks PS support, or the file is damaged/incomplete.
- Open the file with a PostScript-capable tool (for example, Okular on Linux) or convert it with Ghostscript to PDF.
- Re-download or re-copy the file to ensure it’s complete, then try again.
Fonts look wrong or text is missing after viewing/conversion
PostScript output can depend on font availability or how fonts were embedded when the file was created.
- Convert the .PS to PDF with Ghostscript and compare results in a different viewer to rule out a viewer-specific rendering issue.
- If you control file creation, regenerate the .PS ensuring required fonts are embedded or available to the rendering system.
Printing fails or prints incorrectly
.PS is frequently used in printing, but printer drivers/spoolers may not accept your specific PostScript level/features or the pipeline may expect a different format (often PDF).
- Convert the .PS to PDF with Ghostscript and print the PDF instead.
- If a print system specifically requires PostScript, try rendering with a different interpreter/version (for example, updating Ghostscript) and reprint.
Security note
PostScript is an interpreted language; only open .PS files from sources you trust, since malicious content can target vulnerabilities in PostScript interpreters/viewers.
