After running the "AtrMini.app", you may receive the following message: "AtrMini.app", can’t be opened because it is from an unidentified developer.
To overcome this issue you should proceed as follows:
- Click the apple symbol in the upper left corner of the screen;
- Click on "System Preferences" and then "Security & Privacy";
A panel appears next to the phrase "Allow apps downloaded from", you should enable the "Anywhere" option (you may need to first click the lock symbol in the lower right corner of the window to be able to make this change).
- Open AtrMini by running the file "AtrMini.app". After opening AtrMini you can restore the original Security & Privacy options .
