I've downloaded the installer for Mac. When I open it something is happening and ends with a success message and the option to move the installer to the trash. But searching on my harddrive, in the applications folder, there's no 1Password app anywhere.
Note: my system crashed after an upgrade to Sierra. I had to do a clean install of the system an re-install all the apps.
1Password Version: 6.3.5
