About

Microsoft Edge Dev is the Dev-channel edition of Microsoft’s web browser for macOS. The Homebrew cask installs the graphical app Microsoft Edge Dev.app; it is not a command-line-only package.

  • The cask describes it as a multi-platform web browser and identifies this package specifically as the Dev variant.
  • The app is installed in /Applications as Microsoft Edge Dev.app.
  • The cask indicates that the app supports automatic updates.
  • macOS Ventura (version 13) or later is required.

Install with brew install --cask microsoft-edge@dev, then open Microsoft Edge Dev from your Applications folder. This entry is for the Dev-channel app, not a different Edge channel or product.

Install and uninstall

Homebrew installs the app in your Applications folder.

Install without Homebrew

Download the same file Homebrew uses: msedge.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/3a6c483c-a7f4-456e-92aa-928ec781f996/MicrosoftEdgeDev-157.0.4334.0.dmg

SHA-256 only checks that the download is complete; it is not a security certification. See the SHA-256 and download address

Uninstall command
$ brew uninstall --cask \microsoft-edge@dev

A regular uninstall removes the app and keeps its settings and caches.

Deep clean (optional)
$ brew uninstall --zap --cask \microsoft-edge@dev

--zap also deletes the settings, caches and other files listed in the Homebrew definition. They can include data shared with other apps and cannot be restored, and it does not guarantee that nothing is left.See which files are removed
