ok, this is wired, but it worked!
bonjour from apple site (standalone installation) didnt helped.
but bonjour from itunes (extracted like @György-Farkas did) worked.
Have no idea why, might be the version.
Thanks to all!
@ OP
It would be helpful to understand what you plan to do (emulate what?)
Emulate the MIPS CPU core is not hard and has already been done.
Emulate the system+ many peripheral functions (in MT7688) is a completely different story (other than basic storage and network I/O.)
If for a full-blown Omega2 device emulation, how you plan to feed or output signals (real or emulated) to that emulated Omega2?)
