which method you are using to install Yosemite?

If you're using Clover, try turning on halt enabler and fixshutdown. If you're using Chameleon then there's a dsdt edit that does the same thing as fixshutdown.

Hi i've used this installer: http://www.insanelymac.com/forum/topic/298753-boot-usb-os-x-yosemite-chameleon/   what is the DSDT patch? i've search but i've find only for snow leopard, but this is offline --> http://www.insanelymac.com/forum/topic/228673-help-patch-dsdt-to-be-able-to-shutdown/

Open your DSDT with MaciASL, and apply this patch:

into method label _PTS code_regex_not If\s\(LEqual\s\(Arg0,\s0x05\)\) code_regex ^((?:.|\n)*)$ replace_matched
begin
        If (LEqual (Arg0, 0x05)) {}\n
        Else\n
        {\n
%1
        }
end
