KM Thanks. I am in fastboot mode. No need to hit START. That restarts the phone in normal mode.
EDIT: I read that under Developer Options I should set Select USB Configuration to MTP (Media Transfer Protocol) rather than Charging, in order to be able to see the phone on the Mac. No improvement. However, every time I reboot from fastboot I see that the option has changed back to Charging...
2nd EDIT: Same happens if I simply reboot without going thru fastboot. The USB configuration automatically reverts to Charging. If it happens to you too, then that is not the problem. I guess I will have to try with a Windows PC...
