Serviio v1.5.2 on Mac OSX 10.10 (Yosemite) - log file

Dear all,
I have some problem using Serviio v1.5.2 on my new iMac 5k Retina with OSX 10.10 (Yosemite).
First of all I'm not be able to view the log file. I try to search into the " /Library/Application Support/Serviio/config" but no folder "Serviio" exist under the Application Support so no log file is create

Do you have some ideas to find it? Or could you help me to find the config file to specify where is log must create?

Hi to everyboby it's very crazy I can't understand how Serviio could be work if I'm not be able to see "Serviio Folder", Logs ect..

What do you suggest?

Thanks for any replay.

On more thing I didn't install any JRE because I read that the Servio package include in the bundle setup a JRE v1.8.0.40. In yoyr opinion could be this have some effect on my issue?

Thanks

Are you sure you're looking under the system /Library/Application Support, not the user one? (~/Library/Application Support)

Under /System/Library there's NO such "Application Support" folder.

The only folder named "Application Support" is under my user/Library/Application Support but under this folder there's no folder named "Serviio"
