Trackpad not working after macOS High Sierra upgrade
I get a message "there is no magic trackpad connected" for my trackpad. This started happening after I updated my iMac (21.5-inch, Mid 2011) to macOS High Sierra. It was working fine until the upgrade. Is this a glitch in the new macOS? How can I fix it? Please help!
