Where to set unsafe mode in Safari 10 to made java plugin access local file
<p>I just updated my Safari from Safari 9 to safari 10 beta version.
My client is a java applet runs from a page. In Safari 9 and before version, it runs OK. But in Safari 10 beta, it fails.
I found that safari 10 blocks access to local files from Java applet.
So I think it is because the java plugin runs under safe mode.
But in Safari ->preferences->security->Plug-in Settings. 
there is no unsafe mode option to check. there is only three option :Ask,Off,On.
So my client can not access local file in safe mode now.</p>

<p>My mac system is OS X El Capitan version 10.11.6
and Safari version is version 10.0</p>

<p>Is that possible to set Unsafe mode in Safari 10 beta version?</p>
