A while back the T key on my Mac stopped working unless I pressed really hard. Soon the E key stopped working too. Eventually the column of E,D, and C and T,G, and B all stopped working. I tried reseting the SMC which seemed to reset but didn’t change anything. I then went to reset the PRAM. I never heard a second startup chime and MacOS just booted up only it was running at like .2 fps. The only way I was able to fix it was by disconnecting the battery and power cycling the machine. I am also unable to use ANY startup commands including recovery mode, target disk drive, boot selector, and most importantly hardware check. Any help is greatly appreciated.
If a USB Apple keyboard doesn’t work then you have a deep problem! I think the smartest direction here is to find local MacBook expert to review your system. Clearly you have a few different major sections of your system in trouble.
