Hello everyone, First post here! My wife and I just got an iMac, I believe a 2009 (not able to check right now), and were pretty excited about it. I have some ideas about what I want to do with it, and I was wondering if you guys can show me how. I'm especially interested in any insight from people who use both Linux and Mac computers on the same network. We're both pretty new to Macs, coming from a Linux background. My wife incidentally also just recently got an iPad Mini and a Macbook, which she loves, and I still quite enjoy Linux and run it happily on my Lenovo laptop. We got the iMac because we wanted a good desktop computer with solid specs, and particularly because my wife does a lot of video editing, which of course Macs are great for. Here are my questions: 1) Do you guys have any general tips/tricks for transitioning from Linux to Mac? I've played around on Macs before, but never owned one, so that beautiful machine sitting in our office is kind of foreign to me 2) Is there anything I need to know about networking Linux and Mac computers over our WiFi network? We don't have an Airport router, it's an old Linksys thing that has served us quite well so far. My wife has no problem using it with her iPad and Macbook. I'd like to be able for us to transfer/share files over the network with the iMac, Macbook, iPad mini, my Linux laptop and my Android phone. 3) I've been using my laptop as a DLNA media server so we can watch movies on our TV using our Xbox 360, and I'd like to transfer that responsibility to the new iMac -- that way I don't have to make sure my laptop is on every time we want to watch something. I'm currently using Plex on my laptop. Does anyone have experience with Plex on an iMac? Does it work when the computer is sleeping / Do I need to change any power settings on the iMac to get it to always be available for streaming? Any other recommendations for DLNA software on a Mac? 4) I want to keep my music collection on the iMac, but I hate iTunes. Are there any good alternatives? My main concern is not having my media player automatically control the locations and filenames of my mp3 files, or re-encoding them to other formats, etc. I essentially want our iMac to leave my music library alone and just let me view my library and choose songs, without actually changing anything about how it's organized on the hard drive. What I'd also like to do is store all of my music on the iMac's hard drive, and then be able to access it using my Linux laptop over the network whenever I want to listen to it and I'm in another room, etc. Is this pretty doable? Thanks, looking forward to your insight!
