    Use iMac as an Ethernet bridge
    Hello,
    I have a device that requires Internet but only has an Ethernet port (no WiFi). Sitting right next to it is my iMac. I use Wifi to connect my iMac to the Internet and I was wondering if I could use the iMac as a bridge.

    In other words, the iMac continues to connect to the Internet via WiFi but I then plug an Ethernet cable from the iMac to the device in question. Is it possible to do this via the Ethernet cable?

    Yes, you can share the Internet connection of your iMac to another device over Ethernet. It might or might not be exactly a bridge, but as long as the device on you want on the Internet gets there, it doesn't matter, right?

    Open up System Preferences->Sharing, select Internet Sharing and then choose WiFi on top and Ethernet as the how and connect your device and see if it works.

    Yes! it is possible to use your iMac as an internet source. Just open System Preferences on your mac, click on Sharing, then you will see a menu, click Internet Sharing and then to share your connection from, choose WiFi and to computer using, choose Ethernet and Bluetooth PAN. Just follow this easy steps and hope this works on your mac. Goodluck!

    Thanks Raz0rEdge & Maria,

    I just tried that from your link and it seemed pretty easy but it's not working. I have it set up with Internet sharing on (indicator is green) to "Share your connection from WiFI" to "Computers using Ethernet" with a cable from the iMac to my device. The back of the device only has an orange light on (not green) and no connection. Do I perhaps need a crossover cable?

    Thanks

    That's possible depending upon the age of device you are trying to connect. Can you tell us what Mac and what other device you are connecting. The mopre information you can provide the better.

    The device is a BT Mini YouView Box (for UK television and streaming). The iMac is a 2015 5K retina 27"

    It's been a while since I had to use connection sharing. Perhaps someone else can chime in here.

    I don't think the issue is a need for a crossover cable though. I haven't found a definitive answer yet but the iMac should be new wnough to have an autosesning network card that should mean a crossover cable isn't needed. I guess it's worth a try though.

    Do you have a broadband extender connected? Step 3 in the user guide?

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    If by a broadband extender, you mean a power line adaptor no. The Mac is just connected to the Internet via the WiFi.
