Pique

A macOS Quick Look extension for syntax-highlighted previews of configuration files and scripts.

Select a file in Finder, press Space, and get a formatted preview with proper syntax highlighting to make your MacAdmin life easier — no need to open a text editor to glance at a config file.

Requirements

macOS 26.0 or later.

Enabling the Extension

On macOS 26, Quick Look extensions must be explicitly allowed. When you first launch Pique, you will see a notification:

Go to System Settings > Login Items & Extensions > Quick Look Extensions and enable Pique.

Appearance Settings

Open the Pique app and click the gear icon () in the bottom-right corner to open Appearance Settings.

• Per-Format Appearance — every format defaults to System (follows the macOS appearance). You can override an individual format to always render Light or Dark — for example, keep shell scripts dark while Markdown stays light.
• Show Line Numbers — a global toggle that adds line numbers to code previews.

Settings are stored in a shared App Group (group.io.macadmins.pique.apps), so the Quick Look extension picks up your changes on the next preview.

Renewing the Quick Look Cache

macOS caches Quick Look previews and the list of registered generators. After installing or updating Pique — or if a supported file still shows the plain-text preview — renew the cache:

To confirm Pique is registered, list the active generators and look for io.macadmins.pique:

If previews still don't update, log out and back in (or reboot) so macOS reloads the extension.
