Instant Hotspot on your Mac
Lost your Wi-Fi connection? With Instant Hotspot, you can use the Personal Hotspot on your iPhone or iPad to connect your iMac to the internet instantly—no password required.

Connect to your device’s Personal Hotspot. Click the Wi-Fi status icon in the menu bar, then choose your iPhone or iPad from the list of devices that appears. The Wi-Fi icon changes to . (You don’t need to do anything on your device—iMac connects automatically.)
Tip: If you’re asked for a password, make sure your devices are set up correctly. See the Apple Support article Use Instant Hotspot to connect to your Personal Hotspot without entering a password.
Check the status of your connection. Look in the Wi-Fi status menu to see the strength of the cellular signal.
When you’re not using the hotspot, your iMac disconnects to save battery life.
