Quick-fire questions

Why do I need Wi-Fi when my Mac has Ethernet?

> Macs and devices use the combination of Wi-Fi and Bluetooth for connections with Handoff and Continuity. These include AirDrop, Universal Clipboard, unlocking with an Apple Watch, and iCloud Tabs in Safari. When you want Ethernet used in preference, drag it to the top of the list in the Network pane.

Should Macs use DHCP addresses from my router?

> DHCP works best for visitors such as laptops and iPhones rather than more static systems. Fixed devices including networked storage, desktop computers and printers are best assigned a fixed IP address, which saves them having to renew leases. Configure this in the DHCP section of your router’s set-up page.
