I have downloaded the Vivaldi installer for Mac "Vivaldi.2.11.1811.38.dmg" from the Vivaldi website. Then I doubleclicked the installer file in Finder
and agreed to the software agreement. Then this window without text and without buttons was displayed:
It is not clear from this SIGN LANGUAGE dialog what I should do now, as I don't speak the sign language. I have tried to double-click the Applications icon, but it shows only a list of the installed applications.
So how must I proceed now to install Vivaldi on Mac?
