Greetings all, first time poster. I'm new to Mac. Bought a used 2008ish MacBook Pro a month or so ago, liked it so much, got a new iMac. This is a work related computer, and we have 4-6 PC's in the place that will need to get data that will be stored on my iMac. I have moved most all the files from my PC to my iMac, so file wise, I think we're all set. However, I can't get my iMac to be visible or accessible from any of the XP machines. I've searched most of the day for tutorials, etc and here's what I have tried with no success. Forgive me if I say some things the wrong way, I'm not up to speed on all my Mac terminology yet. I went into "Sharing" and turned on file sharing. I selected "Options" from there and clicked on the one that "makes it friendly for PC's". I added a folder to that, the one folder that contains all the files I want people to have access to. I gave "everyone" access to read & write. I went into Network Settings, Advanced, and went to the "WINS" area and gave it a work group name the same as the one used for all the PC's. When I go to a PC, running XP, and select "Network Locations", it'll display on the list and say I don't have authority to connect when I try to select it. With my Macbook Pro, I thought I just turned the thing on, and it seemed like everyone could see me and I could see them. With my iMac, I'm struggling. I'm dealing with graphics files, Illustrator, Photoshop, jpeg's, etc., and I just need the PC's to be able to access the files a create. And if I modify something at the PC level, and save it, I need it to save back at the original location, on my iMac. Any help would be greatly appreciated. Thanks!
