Select your language: English 日本語 Deutsch Français

Attention, Apple has adopted a new security measure in macOS 10.15 Catalina. So now, if you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.

If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.

These warnings mean that the app was not notarized, and Apple could not scan the app for known malicious software. If you also meet these warnings while launching NoteBurner program, please follow the following guide to make NoteBurner run smoothly under macOS 10.15 Catalina.

How to open an app that hasn’t been notarized or is from an unidentified developer


In macOS Catalina and macOS Mojave, when an app fails to install or open because it hasn’t been notarized or is from an unidentified developer, you are able to use it by authorizing on the system settings window.

Step 1: Go to System Preferences > Security & Privacy > General tab. Tap the lock at the bottom left of the screen and enter your password to unlock Security and Privacy.

Step 2: Look for “Allow applications downloaded from:” and choose "App Store and identified developers".

Step 3: In the Finder (blue smiling face icon), locate NoteBurner app and click it, followed that a window will pop up that says "NoteBurner app can't be opened ...", simply click "Ok".

Step 4: Go back to the Security & Privacy window, you'll see a message under the option of "App Store and identified developers" that says "NoteBurner app was blocked from use because ...". Click Open Anyway behind it to confirm your intent to open or install the app.

NoteBurner app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.

Note: If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.
