My father and I got a Mac Mini to work as a home file server, but we have encountered the strange problem the title suggests. We install OS X perfectly, but after we enable autologin (so we can VNC into it immediately without a monitor) the computer simply won't get past the grey apple screen. Please bear in mind that we are extreme server newbies and we are trying to make this sort of a learning experience. Is there any obvious preference we are missing? EDIT: We figured that we should upgrade the RAM, so today we installed 2GB and will test what happens when we install Server. Either way, any ideas?
