Hi guys, my late 2011 MBP is really slow now. It hardly starts up and I can barely get into activity monitor where it shows the system using 97%CPU. I reset PRAM, I tried diagnostics but they didn’t work, I restarted the computer of course. Not sure what else I can do to fix this issue. It’s bogged right down. Would it be the logic board? Hard drive? I did unplug the built in trackpad because it was acting up and overriding the external mouse I use. Could that be throwing it off? Any help would be hugely appreciated! I can’t afford a new one yet, haha.
