We probably feel downhearted if we need to use the debugger to find out what's wrong with our Ada code.
Under those circumstances, we feel even more frustrated if the debugger doesn't work!
This is exactly what has happened with gdb and macOS Sierra.

9-axis means it can measure each of acceleration, gyro and magnetic field values in 3 axes, which is very useful if your drone needs to know about its own motion.

I downloaded a new version of eclipseArduino (Arduino development within Eclipse). After unpacking and moving to /Applications, I get the message
"eclipseArduino" is damaged and can't be opened. You should move it to the Trash.
After a lot of poking around, I found this:
- Open Gatekeeper settings located in System Preferences > Security & Privacy.
- Set Allow applications downloaded from: to Anywhere and confirm by pressing Allow From Anywhere.
- Run the application.
- Once the application has been successfully launched, it no longer goes through Gatekeeper; so, restore Gatekeeper settings to the default option Mac App Store and identified developers after successfully launching the application.
