When you first run Juka on Macintosh, you might get the following error message:


Cannot be opened because it is from an unidentified developer.


To resolve this issue, follow these steps:

Double-click on the Juka app.

  2. Click on the Apple icon in the top left corner of your screen and go to System Preferences.

  3. Click on Security & Privacy.

  4. Click on the General tab.

  5. Click on the Open Anyway button next to the Juka app. step2

  6. You should now be able to run Juka.

Alternative Workaround

You can use the following workaround:

Assuming that Juka is stored on your Desktop, open a Terminal window and navigate to the Juka directory. Run the following commands:

chmod +x ./Juka
sudo spctl --master-disable ./Juka
  1. This will disable Gatekeeper for the current session, allowing you to run Juka.
  2. Once you are done using Juka, run the following command to re-enable Gatekeeper:
sudo spctl --master-enable

This will re-enable the "gatekeeper".
