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.
