[Solved] Unable to install on OSX 10.13


I asked my son who is into animation to try and download and install synfig on OSX 10.13
We can download the dmg file but it will not install.
Synfig Studio can’t be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the app store

We found solution
goto System Preferences
goto Security & Privacy
unlock padlock icon lower left corner
click “open anyway”

Also you can open menu with Ctrl+Click on SynfigStudio.dmg and choose Open.
