I have been using the "magic Trackpad" for years with no issues. I think I left it and the computer unattended a few days and the batteries went completely dead. Now it will not connect.Had to dig out a wired mouse. I think the computer went thru an auto update during this period to OS 15.3.2.Could be a contributor?I have tried all of the normal things, new batteries, restarts, ect. :sos:
