Need some help. My macbook's battery died today, which I rarely ever let happen. Once I plugged it in and turned it on, I noticed that any type of scrolling became very slow and laggy. My pointer moves fine, as does the magnification of the apps on my dock as I hover over them. Silky smooth. But when I swipe to shuffle through my desktops or even scroll with two fingers up and down a webpage, it becomes incredibly laggy.
I've restarted and also shutdown and let it rest for a few hours before turning back on. Nothing. Any idea what happened and how I can fix it? Thanks in advance!
