Frequently asked questions

The Mac App Store edition asks me to choose a download location first

On first launch, open Settings → Basics → Download location, click Browse…, and grant access to a folder visible in Finder through the macOS folder picker. BenLiu does not save your downloads into a hidden app container.

The browser extension cannot connect to the desktop app

Make sure BenLiu is running. The extension sends download requests only to the local loopback address 127.0.0.1:21176 and never uploads them to BenLiu servers. A firewall or a port conflict can block the connection. The extension works with the website edition only.

A download fails after the task is created

Check that the link still works and opens directly in a browser, and that the download folder is writable. Sites that require sign-in may depend on a valid session or a temporary link.

How do I update the Mac App Store edition?

The Mac App Store edition has no in-app update check or installer. New versions are announced and installed by the App Store. The website edition and the store edition update through separate channels.

What each edition includes

The Mac App Store edition supports regular HTTP/HTTPS file downloads, the queue, pause and resume, speed limits and categories. It does not include the browser extension, video site resolution, third-party downloaders, serial number activation or in-app updates. For the website edition, see the home page.

For local task records, browser extension data and network requests, see the privacy policy.
