I wish qDSLR working with my Sony α9(not α9ii ).

Yes I read about it.
Unfortunately this is only for Windows, so no use for qDD.
Would be much better if Sony just released the PTP protocol they use then to develop a new SDK.

you could consider making integrate it into the windows version of qdslrdashboard.
I would buy a windows tablet, if it would work good and would be the only solution
Way better than nothing!!!
