JBridge is useful for running VST32 in 64Bit DAW's so when the BB64 is released soon you can still use it with VST32.
As for Mac updates it's never ending all the cats all the mountains all the apps that don't work anymore, I'm still on 10.9 it works fine I just use Sierra wallpaper smile I don't think you get those problems with Win, XP apps still work on 10.
