Hi everyone,

I am running the current macOS Sierra public beta3 and everything is fine so far besides one thing. Since beta1 I cannot install any Safari extensions anymore. Neither via Safari Extension Gallery nor from the publisher directly. I tried different extensions but not a single one can be installed anymore. When pressing install, I always get the same failure message:

Safari can’t install this extension
An error occurred while installing the extension “XYZ”.

I'd really appreciate any help to fix that matter, thank you guys.
