I have a networking question. Currently, my Mac connects to the Internet wirelessly, and an Ethernet cable connects it to my Windows PC, which doesn't have Internet access. I have Windows sharing set up on my Mac so the two computers can exchange files. I was wondering if enabling sharing on the Windows PC instead of the Mac and connecting to the PC from the Mac would be more secure. If so, I can simply use the networking guide here to set everything up. Also, is the Mac firewall going to cause problems? I have it enabled.
