Hi, I've been researching this to death and just can't find anyone else that has posted about what I'm looking to do. I have a wifi network set up using an existing route/modem. I want to use Time Machine on that network, but not as a router/modem. From my understanding this is possible. But, this will be a shared network with other users. Am I able to use it on this network securely, so only I am able to access it from my macbook ? I do not want any other users to be able to access my time machine back ups/or other file back ups and I do not want other users to be able to use the Time Machine for back up either. Follow up question, is there other external hard drives out there I can accomplish this with ? Hope this makes sense, thanks!
