Hey BRADPETIT That is a weird behavior that you are experiencing, make sure to start you have no bluetooth mouses, corded mouses, or wireless USB mouses connected to the MacBook. If you are using the onboard trackpad, open “System Preferences” and check the trackpad behaviors to see if it could be one of those. If everything seems to be ok. You could try to reseat the connector for the trackpad. For MacBook Air models it looks like a cable very similar to the battery connector, that is seated right above the trackpad frame. You should also check to verify that there is no debris, obstruction, water damage, and or scratches on the trackpad. By reseating the cable, this to a point resets the hardware and may solve your problem. I doubt this issue is anything related to software, especially after you said you reinstalled macOS. You can try another trackpad from your donor MacBook just to see what happens. If you still encounter the error it probably would be best to replace the trackpad altogether. Good Luck!
