How to Download and Install Quicksilver on macOS

Quicksilver is a free, open-source macOS productivity app available from its official site, qsapp.com. You can install it in two ways: download the app directly from the site's Download button, or install it via Homebrew. The site lists a macOS version requirement alongside an "All versions" link, so check that your Mac meets the stated minimum before installing. No pricing or account requirement is mentioned on the page.

Before you install

• Platform: macOS only. Quicksilver is described as a macOS productivity application.
• Version check: The site shows a version number next to a "macOS +" requirement and an "All versions" entry. Use the "All versions" link if you need an older release for an older Mac.
• Cost: The site states the app is "Open Source" and "Free forever," so there is no purchase step.
• What you get: A keyboard-driven launcher for starting apps, opening files, and running actions, plus a plugin system for extending it.

Option 1: Download from qsapp.com

1. Open qsapp.com in a browser.
2. Select Download (the primary button on the page; a second "Download Quicksilver" button appears at the bottom).
3. Confirm the version shown matches your macOS version, or use All versions to pick a release that does.
4. Open the downloaded file and move Quicksilver into your Applications folder when prompted.
5. Launch Quicksilver. On first run, macOS may ask you to confirm opening an app downloaded from the internet — approve it in System Settings if the prompt appears.
6. Grant any permissions the app requests (for example, accessibility access for keyboard triggers). Without these, global shortcuts and some actions won't work.

Expected result: Quicksilver runs in the background and responds to its activation shortcut, letting you type an app or file name and launch it.

Option 2: Install via Homebrew

The site offers an "Install via Homebrew" path for users who manage software from the terminal.

1. Make sure Homebrew is installed on your Mac.
2. Use the Homebrew install command shown on the site for Quicksilver (the page links to it under the version line).
3. Wait for Homebrew to fetch and link the app.
4. Launch Quicksilver from Applications or Spotlight and complete the first-run permission prompts as in Option 1.

Expected result: Homebrew reports a successful install, and Quicksilver appears in your Applications folder like a manual download.

After install: what to set up first

• Activation shortcut: Choose the key combination that brings up the Quicksilver interface. This is the core of the "act without doing" workflow the site describes.
• Interfaces: The site notes 10+ interfaces with color theming, so you can change the look of the launcher window.
• Plugins: Extend functionality as needed. The site lists examples including Mail (send email via Apple Mail or Gmail), Calculator, Clipboard & Shelf, browser control for Safari/Chrome/Firefox, Calendar & Reminders, Emoji search, and image manipulation (resize, crop, convert).

Common snags

• Shortcut doesn't respond: Usually a missing accessibility permission. Re-check System Settings privacy entries for Quicksilver.
• Wrong version for your macOS: Use the "All versions" link rather than the default download.
• Homebrew install fails: Confirm Homebrew itself is current; the site's command assumes a working Homebrew setup.
• Plugins not appearing: Plugins are installed separately from the core app — check the plugin catalog linked from the site ("Explore All Plugins").

Which route should you pick?

Either way, the result is the same free, open-source app; the choice comes down to how you prefer to manage software on your Mac.
