Resposta para "Cursor jumping randomly when typing"Same problem. I had the problem with my midyear 2015 MBP 15”. After 4 years, I traded it in on a 2020 MBP 16”, knowing that the “jumping cursor” problem would have been fixed after all this time. I AM SO DISAPPOINTED. I have been a loyal Apple user since my first Apple //e and LISA computers back in 1983. Are there any class action lawyers out there reading this???
