mouse pointer start lag
Since last week, my mouse pointer start lag, and I have Apple bluetooth mouse and Apple bluetooth keyboard. But that is not the point, even though I disconnet both bluetooth devices, and using trackpad my mouse pointer still lag.
I have tried to use reset PRAM (apple/option/p/r) and still not solve the issue.
I have tried to reset the SMC (left shift/control/option) with power button and wait for 5 second to reboot, and still not solve the issue.
I have uninstall i-stat in my dashboard, and the issue still exist.
I have turn-off the airport connect and the issue still exist.
I have tried to disconnect all the external devices such as bluetooth and external display, and the issue still exist.
I am sure that this is not the bluetooth issue, and I believe that must be some program conflict in my system. and even I use the trackpad and the mouse pointer still have the lag issue.
Does anyone know how to check if my system has been conflict or any log I can check?
Can any one give me other solution and I can keep trying to see if the issue solve.
Please kindly give me some suggestion and I will try to see we can sort it off.
by the way, I took my mbp to apple store, and they rest PRAM and the issue disappear in the store, but when I take it home, the issue appear again. That is so weird.
