How can I use software that is not "safe"? I've been trying to use drawing/painting software like Inkscape and krita but they won't open because the software may not be "safe" for my Mac. Does anybody know how to enable the software so that it will work?
just:
- Right-click (or control-click) the application in question and choose “Open”
- Click the “Open” button at the next dialog warning to launch the app anyway
