How to fix MacBook Pro Track Pad/ Keyboard Issue

MacBook Pro Trackpad and Keyboard Issue (Fix!)
I’m teaching last week and my trusty MacBook freezes and won’t allow me to use my track pad or any of the keys... I still had one more class to go and I didn’t have time to go to Apple and replace the part, so I had to use my ingenuity ASAP! After scouring the internet for about 20 mins, I was unable to find a “quick fix” so I started getting “hands-on” in a desperate attempt to fix the track-pad/ Keyboard. At some point I decided to plug my classroom projector into the hdmi port as I reset my computer and “viola”! It worked! Not sure exactly how or whether or not it will work for you, but if you are desperate and need a quick fix, it wouldn’t hurt to try, right? Please lmk if you know why this does work or if it helped. (Shout out to all my teachers out there helping shape the world. (Hopefully for the better) And if you aren’t a teacher 👩‍🏫 👨‍🏫, I still hope you find this useful! Peace ✌️ and positivity!B
