Hi everyone, I have a 2008 Mac Pro (Mac Pro 3.1) running 10.6.8 Snow Leopard. The computer has an airport extreme card. I use an Ethernet only modem to connect to the internet. I have tried all of today to get my son's iPad Air and iPhone 5S to share my computer's internet connection, without real success. I did a Google search for "sharing internet mac iPad iPhone". I have tried airport, I have tried Bluetooth, I have tried a few of the methods thrown up by my google search, but I just can't get it to work. My son also has a 2009 iMac, which connects to the internet via my Ethernet modem, and he has no issuse sharing the iMac internet with his iPad and iPhone. I just can't figure out what I'm doing wrong. Any help would be greatly appreciated. Thanks in advance.
