I have installed the KiCad Software for OSx from the download section -so far so good -
The installation works fine …
but if I try to start the KiCAD the OSx gives the following message:
“KiCad could not start because it didn’t come from a certified developer”
is there a workarround to start the Application?
Did you try to right-click (or control-click) and select “Open”?
Yes, the result is the same…

Note: Another way to grant
an exception for a blocked app is to click the “Open Anyway” button on
the Security pane of System Preferences. This button is available for
about an hour after you try to open the app.
To open this pane, choose Apple menu > System Preferences, then click Security & Privacy.
