keyboard lag on macbook pro
I have a Macbook Pro 2011 which i had cleaned and upgraded two year ago incl 500 gb SSD (over 250 spare capacity) I now get a severe lag when type in my password to unlock the screen when ;s scree locked. If I turn it off and log back on again it's fine. How can i fix it?
