Hi everyone my MacBook 2014 was working fine until yesterday and today morning I installed the pending updates Big Sur 11.2.1 and found my trackpad completely not working and keyboard randomly struck . And found many users are having the same issue after update .

hi everyone today morning i got the trackpad and keyboard issue , i connected to apple support and after some discussion they suggested to reset smc which worked for me please do try if it works for you ,
Please follow the below :
please shut down your Mac. And using the built-in keyboard, press and hold Shift-Control-Option keys on the left side of the keyboard then press and hold the power button at the same time. Hold these keys and the power button for 10 seconds then release all the keys. You won’t see any response on your Mac while pressing these keys. After 10 seconds, release the keys and press on the power button again to turn on your Mac.
