Test builds for Mac and Windows

Pre-release software, handed out for testing. Expect rough edges, and please report what you hit. Every file below shows its exact size, and each card has a Verify this file link with the SHA-256 if you want to confirm you got what we published.

Read this before you open anything (macOS)

These builds are ad-hoc signed. They are not signed by a registered Apple developer and they are not notarized. macOS may refuse to open an ad-hoc signed app the first time. Whether it actually does is still being tested — you may well get straight in. If macOS does refuse, here is the route:

  1. Double-click the app. If macOS refuses it, click Done on the dialog.
  2. Open System Settings → Privacy & Security and scroll down to the line naming the app. Click Open Anyway, then confirm. Every launch after that is normal.
  3. On macOS 14 or earlier only: right-click (or Control-click) the app and choose Open, then Open again. This no longer works on macOS 15 and later, which is why it is not the first step.
  4. Still stuck? Strip the quarantine flag in Terminal, then launch normally: 
    xattr -d com.apple.quarantine /Applications/<App>.app

Only do this for a file you got from us and whose SHA-256 matches ours. Open Verify this file on the card to see the hash. That check is the reason the hashes are here.

On Windows: nothing we build carries an Authenticode certificate, and that is a settled decision rather than a gap waiting to be filled. Windows cannot tell "unsigned" from "unknown", so SmartScreen will warn about anything we hand you. The SHA-256, under Verify this file on the card, is what you check instead. Where a Windows build is not downloadable, its card says so and says why, rather than being left off the page.

Check what you got

From Terminal, in the folder you downloaded into:

# prints the hash — compare it to the card above
shasum -a 256 <file>

# prints the size in bytes
stat -f%z <file>
