I have a Mac pro operating system 10.5.8 with 2 quad processors. With 10.5.8 I cannot read any of my files from my old mac operating on system 9.?. I just found my copy of Quark 6.0 and it actually installed on the new Mac fine, but when I tried to transfer some Quark 5.5 files to the new mac they came up greyed out and with exec as a label. I copied the file on to a memory stick. Can I transfer these files? Any way of opening older CD of clip art on the new Mac?
