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.
Which Ethernet adaptor for my M1 MacBook Pro?
> There’s no difference in network speeds achieved by plain USB-C and more costly Thunderbolt models. If your Mac has only two Thunderbolt ports, look for an Ethernet adaptor with USB-C charging pass-through, additional ports such as USB, or a buy a smaller mini-hub, for greater flexibility.
How to tell if my old Mac mini supports AirDrop?
> å-click the apple menu and select System Information…. From there select Wi-Fi in the Network section, where it should tell you clearly (near the top) whether AirDrop is supported, and its current channel number.
