After downloading the Designer from Stambia.org and installing it, the Stambia application won't start.
A macOS popup appears with an error like "Stambia quit unexpectedly" (en français "Stambia a quitté de manière imprévue").
MacOS High Sierra applies specific security policies to Applications downloaded from the Internet.
Possible workarounds include :
- transfer the Designer's zip archive to an FTP server and download it again with FTP => it will suddenly work
- start the Designer from the command line : stambia.app/Contents/MacOS/stambia
- download the zip from stambia.org using Windows or Linux, and then copy the zip to macOS through your local network or a USB key
Note: other macOS versions don't seem to apply this strange locking policy, but in case you observe it please inform our Support Team.
