Installing MD DOCS on macOS

The Mac version of MD DOCS is code-signed with an Apple Developer ID, but it is not yet notarized by Apple. Because of that, macOS shows a one-time security prompt the first time you open it. This is normal — once you approve it, MD DOCS opens straight away every time after.

Follow the steps for your macOS version below.

macOS 15 (Sequoia) and later

Apple removed the old right-click shortcut in Sequoia, so the approval now lives in System Settings:

  1. Double-click MD DOCS (in Applications, or wherever you put it).
  2. A dialog says it can’t be opened because Apple can’t check it for malicious software — click Done.
  3. Open System Settings → Privacy & Security.
  4. Scroll down to the Security section. You’ll see a message like “MD DOCS was blocked to protect your Mac.”
  5. Click Open Anyway.
  6. Confirm with Touch ID or your password, then click Open.

That’s it — MD DOCS now opens normally from then on.

macOS 14 (Sonoma) and earlier

  1. Right-click (or Control-click) the MD DOCS app icon.
  2. Choose Open from the menu.
  3. In the warning dialog, click Open again.

MD DOCS launches and is remembered as safe, so future launches just double-click as usual.

Optional: Terminal shortcut

If you’re comfortable in Terminal, you can remove the quarantine flag so there’s no prompt at all:

xattr -dr com.apple.quarantine "/Applications/MD DOCS.app"

Adjust the path if you installed MD DOCS somewhere other than Applications.

Tip: avoid the prompt entirely

The security prompt is triggered by the quarantine flag macOS adds to files downloaded from a browser. If you transfer the MD DOCS app to the Mac via AirDrop or a USB drive instead of downloading it, the flag usually isn’t added — and you won’t see the warning at all.

Why does this happen?

  • Signed means the app is verified as coming from a known developer and hasn’t been tampered with.
  • Notarized is an additional Apple service that scans the app and lets it open with no warning whatsoever.

A signed-but-not-notarized app is safe to run; macOS just asks you to confirm once. A future MD DOCS release that is fully notarized will open with no prompt at all.
