How to share your internet connection over Wi-Fi in macOS Ventura – Macworld

Internet Sharing has long been Apple’s way of letting you take an internet connection used by your Mac and share it with other people and devices–also called a hotspot. This is useful when you don’t have a Wi-Fi gateway you can use or there’s a restriction that makes your Mac the sole device with an internet hookup. With the reorganization of preferences in macOS Ventura, you might have to hunt down this feature if you need to configure it; consider this a how-to guide for Ventura whether or not you’ve previously set up a macOS hotspot.
Typically, you share a connection coming in over ethernet via Wi-Fi, and that’s what I explain in the steps below. However, you can also share Wi-Fi over ethernet and other combinations.
Here’s how:
(Apple hasn’t rethought this message for many, many years. It ends with the odd advice for home users, the most likely to use it, to “Contact your system administrator before turning on Internet sharing”!)
Apple doesn’t let you share Wi-Fi to Wi-Fi, as macOS doesn’t include the capability to create virtual Wi-Fi networks, an option required to both connect to a Wi-Fi network and create a separate one.
In step 7 above, choose a high-numbered channel (36, 40, 44, or 48) for greater range than the low-numbered channels (1, 6, 11). The high-numbered channels use the 5GHz frequency band, available on all mainstream electronics, including all Apple hardware, for many years. If you have older gear that can only use 2.4GHz connections, choose 1, 6, or 11.
For Security, Apple offers WPA2/WPA3 Personal or WPA3 Personal. In most cases, pick WPA2/WPA3 for compatibility. WPA3 is widely available but appears mostly in hardware released in the last few years. From a security standpoint, it’s not substantially different than WPA2.
