Device name- macbook pro 2018 (model A1990).
My trackpad sometimes doesn't work. As example, everything works fine from the boot-up/starting when it works. it works fine for days. Then i shut down my macbook and restart after several hours. Trackpad stops working from the boot-up/starting, cursor, haptic, secondary click, nothing works.
Sometimes SMC reset fixes the issue (not everytime). I have already tried NVRAM/PRAM reset also, doesnt help. Tried diagnostic too, no issue found.
Again if i shut down now then trackpad may work again in next boot-up.
What may cause the issue?
Thanks and Regards
