Unable to build OSX on High Sierra 10.13.3 and Unity 2017.3.1f1

Hi Guys, i've a problem that i hope someone help me to solve.

I've updated my system to High Sierra 10.13.3 and I've also Downloade Unity 2017.3.1f1.
The problem is that i cannot build my OSX Standalone Project because i receive some errors.

Here below the errors :
(n.b the serialized multiple times error was present also in the previous project (unity 2017.2) but the build
it was fine).

I've tried :

1. reimport assets
2. close and reopen Unity
3. Removed Lybrary Temp etc etc but nothing.

Hoping that someone can help me
