I just want to up this "wanted Feature".
I think with an ever growing MAC community it is unacceptable that they advertise with mac compatible and have the surveillance station only working properly under windows. There're some developers at Qnap that have Mac's, i'm sure, otherwise we had no Time Machine support either.
As mentioned before, the surveillance station is already more then 2 years old and need an overhaul. A limited software version of the NVR series for example. A possibility to upgrade to more then 4 camera's with a wider selection of models. Look at the competition! If they can do it why not Qnap?
I love my Qnap but this is for me the only negative!
