The trackpad fails to respond after the computer got hung on a website video last night and then went into sleep mode. On wakeup I had to use the arrow keys to toggle through various apps and quit them, then held down power button to allow shutdown. It took 3 times through this routine before I got all apps shutdown before a shutdown. On restart, STILL no trackpad.
Just installed Catalina a week ago. No problems with trackpad initially, probably unrelated to Catalina?
I can use a USB or wireless mouse. I ran Disk First Aid, no help, no problems found. Should I reset the PRAM or something? How is that done? -- hold down P, R, command and option on restart bong? Cannot recall.
