So I've been grinding on the problem the last few days and finally found a solution last night. Found joiner program that was mac-friendly.

Thanks for the help though! I do appreciate it!
What, I just click and drag the iso file onto desktop? Or I copy 001 onto desktop, then select all the other 28 files and drag on top of the mounted ISO oo1? Not sure I'm following.
Long story short. I have 29 small 200mb ISO files. When I had a pc I used winiso to merge these files into one iso file. I cannot seem to figure out how to do this on a mac, however. Any program out there that does this? Thanks for anything you can tell me!
