Quick-fire questions

Why won’t my Mac wake up over the network?

> Tick the box to Wake for network access in System Pref’s Energy Saver pane. On an Intel Mac, if that doesn’t work try resetting the SMC according to bit.ly/mac383smcreset, then check again. You can’t reset the SMC on an Apple silicon Mac, though.

How to set my Mac to sync with an NTP server?

> Network Time Protocol (NTP) servers deliver your Mac accurate time to set its clock. This should normally be set to the default in the Date & Time tab of the Date & Time pane, by ticking the checkbox to set it automatically. If you have a better alternative, paste the location of that NTP server in the box.
