I have a new Mac running High Sierra and with a Magic 2 track pad. The pad suddenly stopped talking 2 days ago. I had to reboot the computer, and I may have done something that the pad didn't like when trying to get Voiceover to come back. I have tried turning on the track pad commander. I also found the place in system preferences that said the pad was connected. The only gesture that seems to work is opening Mission Control. Please help.
