Hi everyone. I have a Mac pro 3.1 which I have upgraded over many years from Leopard, Snow Leopard and now up to Mavericks. During all this time, I have always set the firewall in the OS Security panel to ON. Recently, for the first time, I decided to use this computer as the main internet point for all devices in the house. This means I need to share the computer's ethernet connection via wifi. I'm not sure if I'm doing something wrong, but the various devices will only connect to the network if I turn the Mac OS firewall off, which I'm reluctant to do. So my question is : can I share my computer's internet connection via wifi, but keep the firewall on ? And if so, how ? Any help would be much appreciated. Thank you.
