I have an issue getting the discrete graphics card to activate. The About This Mac screen shows only the Intel Iris Pro active.
I've checked that Automated Graphics Switching is enabled in the Energy Saver system preferences. gfxCardStatus shows Intel as active even when I select the Discrete Only option.
I've tried closing any open applications in case something was using the graphics but I'm still unable to activate the discrete graphics.
Does anyone know if there's a command I can run to check if a process might currently be using the integrated graphics? Is there any other way I can try to get the discrete graphics enabled?
Thanks in advance!
