Slideshow

What is Slideshow?

Slideshow is part of the Racket ecosystem and is documented by the Racket project, with Matthew Flatt listed among its authors and maintainers. It is a programming-oriented presentation tool: instead of editing slides visually, you write Racket code to define slide content, layout, text, images, and animations. The tool is commonly used by developers, educators, and researchers who want reproducible presentations or who already work in Racket. Its documentation describes it as both a slide-presentation language and a library built on Racket and pict, and it supports tutorial-driven onboarding through the slideshow executable. On macOS, users are most likely to encounter it as a component installed with Racket rather than as a mainstream standalone consumer app. Because it is tied to the Racket toolchain, related files and behavior may depend on how Racket was installed and which version is present.

Key features

• Create slide presentations by writing Racket code
• Build layouts with pict-based drawing and composition tools
• Support staged slides and programmatic presentation flow
• Offer fullscreen and widescreen slide modes
• Generate printable output such as PDF or PostScript
• Integrate with the broader Racket language and libraries

Safety overview

Status: Safe

This is a legitimate Racket presentation component, not generally associated with malware. The main risk is ordinary document and project data you create with it, plus any Racket packages or code you choose to run.

Recommendation: Keep it if you use Racket, teach with code-driven slides, or open Racket-based presentation projects. If you do not use Racket or Slideshow, it is usually optional and can be removed as part of uninstalling the broader Racket environment.
