This may be a really stupid question but, when I post something in Freestuff made on my PC, how do I know whether it is Pc only or Pc/Mac? I'd like to make stuff available to Mac users but don't know how.

Mac users can convert most Poser PC files with Maconverter ;)

It will be PC/MAC as long as you put the stuff up in a ZIP, and not in some kind of self-extracting or self-installing EXE, due to the utility eyecatcher mentioned.

Eyecatcher, Jim, Thanks alot, now I know what I'm doing, as much as I usually do anyway.

zips are good for Macs, and Mac OS can now handle most Windows self-extracting exe files that expand to documents like 3ds files, dxf files, obj files etc.

Actually we can't handle most exe files but as Jim said the zip's are fine ...

I think it is possibly what version of stuffit you have and other things ... I know I can't touch most of them even though I have the most recent free version of stuffit.

I've also had some trouble converting PC Poser Pro Pack files to mac.

Mac Stuffit Deluxe 5.5 and later will usually handle exe files that are compressed documents the free version usually won't, as you've seen

If you want the widest distribution, stick to the simplest and most common methods. That means straight .zip files without the .exe versions. It's a form of trade-off between the greater power of the special extraction utilities and the wider applicability of the more "standard" zip. - JimX

Thanks all, I only ever use zips, so should be OK.
