Welcome to the group! :) First, go get Martin's programs to convert and install your files, and give him a tip of the hat and word of thanks for making our lives so much easier. MacConverter puts the right luggage tags on the files so that Poser will open them. MacInstaller will decode pcfs automatically and checks for required prior installations. The best part is now YOU get to control your library layout and tell MacInstaller where YOU want things put. :) I will make the folders in Runtime before opening MacInstaller, but this allows me to organize them. Second, beware of long file names, especially on textures. I don't think OSX has the same problem, but OS9 has a 31 character limit. (If you can't name a texture or prop or file in 31 characters, the fuzzy logic isn't inside the computer?) A corallary to this is that some people who have made CDs of Poser goodies burn them with whatever application came on their computer system and they are not jolietted properly for reading across platforms. The Mac will try to read the file name as a DOS name! (This includes a couple of famous and generous people around this part of the woods.) VistaInternetProducts has a link to the joliet decoder site (I don't know if off the top of my head). A properly burnt CD can be read on any computer, if yours won't read, you will need the decoder. I'm not sure about moving DVDs from machine to machine. My Mac will read PC-only DVDs (that is my only way of watching movies since I do not have a TV). This 4-year old Mac has some movie making software on it. The newer ones come with even spiffier stuff, so you ought to be able to take any Poser animations you may have and make and burn small movies natively should you so desire. If you have cross-over cables, or aethernet with a hub, you ought to be able to transfer the bulk of your files directly without having to burn everything. OTOH, if you do make CDs, you also are making a backup! :) If you stick a PC-formatted zip disk into a Mac it will identify it as a PC disk, and open it cheerfully. PhotoShop files open just fine on either machine, for example. If you stick a Mac disk into a PC, the PC gets all snotty unless you buy some software for recognition. So even though I do all of my graphics on the MAC, I realize that this is a PC-centric world and send them out on PC disks or in PC format. As you may have gathered, there are enough of us here, so that if you have specific questions, just raise a hand and we'll try to help. Carolly
