Building D6 Downloader on your Mac

This app isn't sold on the App Store, so building it on your own Mac is a one-time, few-minute step. Nothing stays installed on your system except the app itself.

1

Unzip the file you downloaded

You'll see 4 files together in one folder:

app.pywd6_logo.png d6_bg.gifbuild_mac.command
2

Double-click build_mac.command

If macOS says it can't be opened, right-click it instead and choose Open → Open. A Terminal window appears and does everything automatically — downloads what it needs, builds the app, then cleans up after itself. Takes a few minutes.

3

The app opens automatically when it's done

You'll find it at dist/D6 Downloader.app inside that same folder. Drag it into your Applications folder.

4

First launch: one security step (normal, one time only)

macOS blocks any app that isn't from the App Store the first time you open it — that's not a bug. Go to System Settings → Privacy & Security, scroll to "Security", and click Open Anyway next to D6 Downloader. After that it opens normally forever.

Why build it yourself instead of downloading a ready app?
A pre-built Mac app has to be zipped and sent to you, and that transfer step is exactly where Macs tend to flag it as "damaged" or blocked. Building it fresh on your own Mac skips that entirely — it's the most reliable way to get a working copy.
