Recently to mac system. After installing my development tools over application folder. I have trouble to set permission to all child files & folder inside. Finally manage to solve the issue. Step as below
1. From Mac Utilities. Open Teriminal Window
2. Run Command : sudo chmod -R <foldername>
3. Press Enter, and enter admin password.
4. Done 😛
