After up-dating to PD12 and macOSierra the camera sometimes didn't work, MacBook reset helped. Now by practical consideration defined that the camera is turned off, after PD start (and it isn't necessary to launch Windows enough start of PD, "Open the general access to the camera Mac for Windows" it is off) Has solved problems with lag of a mouse addition at start : "devices.usb.mouse=0 (vm config -hardware-boot order - advanced settings)" But now is not working extra mouse button. And the new problem already 4 times a mouse lost complete control over Windows on PD12 (in macOS everything worked), helped only restart of PD12. p.s. MacBook retina 15" (2012), PD 12.0.2, Windows10, macOS Sierra (Today has updated to 10.12.1, and problems have remained) Long ago I use PD it is the most problem version!
