Weird pattern/glitch on MacBook Pro after booting up
After I power on and enter the password, the loading bar comes and then this weird glitch-like screen shows up.
Certain keys of my Macbook are also not working so I am unable to enter the various inputs to reset NVRAM, etc. I don't think pressing those keys on an external keyboard is working either. Is this a hardware issue or something that can be resolved easily?
The MacBook Pro is the 2012 model
