Hi Layal, I seen this image before. From what I have seen it is a permission on Mac, depending on your OS version. Here is the way to get around it:
- When decompressing the .zip, the application contents didn't retain the execute bits. Add it back with running on the terminal
sudo chmod -R 755 /path/to/app. - Since the application was downloaded by a web browser (in my case) the quarantine bits are set on the decompressed files. Remove that with running on terminal
xattr -dr com.apple.quarantine /path/to/app. (You may need to use sudo, but shouldn't be necessary.)
If those options doesn't work, let me know. Thank you for informing this issue. Have a wonderful day!
