The Dark Art: Why “Blackmagic” Doesn’t Mean Voodoo

The name “Blackmagic” comes from the developer — Blackmagic Design, the Australian company behind DaVinci Resolve and high-end cinema cameras. Their disk test isn’t a generic utility. It’s tuned for their world: real-time video capture and playback.

So when the app tells you your drive is too slow for “2160p50,” you’d better believe it. Dropped frames are around the corner.

First Launch & macOS Security

When you first open Disk Speed Test from your Applications folder, macOS may show a warning:
“Disk Speed Test cannot be opened because it is from an unidentified developer.”

To fix this:

Right-click (or Control-click) the app icon.
Select Open from the menu.
Click Open in the pop-up dialog.

You only need to do this once. The app will launch normally thereafter.

How to Download the DMG Safely

Because Blackmagic Disk Speed Test is free, it is hosted on several third-party sites. To ensure you are getting a virus-free, legitimate version, follow these steps:

- Tip: Always scan a downloaded DMG with your antivirus software if it is not sourced directly from the developer.
