Activity Monitor - pkd and extreme overheating
I have OS X El Capitan Version 10.11, the latest of which I downloaded last night for my 2011 Macbook Air. All other applications are updated as well, except iPhoto 9.6.1, which whenever I press update, sends a pop up saying that it's not available yet. Anyways, every time I open the App Store after all the other updates, which I did as soon as I went on my laptop today to attempt updating iPhoto again, the fans go overboard and my laptop rapidly becomes extremely hot. I opened Activity Monitor and saw that something called "lsd" and "pkd" were at around 130% CPU each. I closed down App Store and the fans eventually slowed, although my laptop's still warm to the touch.
My battery health is dismal and it has the "Replace Now" tag, but it doesn't seem cheap, so I'm hoping to hold out a bit longer. I use a charger from my old white 2008 macbook because the wires frayed in my Mac Air one, surprise surprise Apple, so I'm not sure if there's an incompatibility that contributes to battery health/overheating issues.
I have absolutely no idea how to interpret what goes on in Activity Monitor, so if someone could take a look, it'd be much appreciated. When I just open the App Store, lsd and pkd stay below 100% but if I try to update iPhoto, it shoots up to well over 100% each. I didn't want to overheat my laptop again, so the %CPUs in the screenshot don't represent the extreme overheating stage, but it's always that "lsd" and "pkd" processes. What are they and how do I prevent them from overheating my laptop? Pkd wouldn't force quit for some reason, it eventually just disappeared on its own.
Also App Store takes absolutely forever to load. Not sure if this is normal.
Thanks!
