Macbook camera sometimes not available in OF - bug?

OSX 10.12.6 OF 0.9.8
Macbook camera quite often is not available to ofVideoGrabber. To reset you have to go into terminal and type:

sudo killall VDCAssistant

Then open quicktime player and select it in’ new movie recording’
Then OF can access it again.

Can this be fixed from OF? It used to work fine on previous OSX versions. My grabber apps are
now unusable…

The last version of OF (0.10.1) contains a couple of fixes, some of them related to OSx, I would try that one.

thanks - will give that a try.
