Chosen Solution
Last week, I opened my macbook up and entered my password as usual, but when I logged in and tried to actually USE the laptop, I found that the keyboard and trackpad were very very, laggy, as in I would type something and I would sit and wait a solid ten seconds for it to actually work. I used a plug-in and bluetooth mouse and they both worked fine, however the trackpad did not. I tried restarting the laptop, but it wouldn’t turn on again for a while.
