I found that if I shut my macbook pro down and wait about 5 minutes or more before restarting it, the erratic touchpad problem goes away for a while. If I shut it down and take the back off of it and let it air out for a while before replacing the back, it is good for several days. I have no idea why this seems to help, but it does. It's like black magic. I sometimes think that it is a heating problem, but it happens some times when the computer feels quite cool. Right now I am running without the battery charger plugged in. I have been using a "generic" charger, so that could be the problem too. I will be looking at that more closely in the future. I'll let you know what I find out. 30 June 2023 by J Paul
