The included macps2pdf is extremely useful: converts ps->eps, fixes eps, does other conversions (handy for TeX, etc). The author gave me an unlock code, after I paid my shareware fee, in 2003 and it still works, two full versions later! PS Viewing is immediate, unlike Preview and Xwin, and zooms in on parts of the figure with a click of the mouse. For my work, the package has been indispensable.

If you don't need the Postscript stuff, you might want to take a look at PDFpen before buying this. It is done by the same people who did PageSender, that brilliant piece of Fax software that finally brought a supported working Fax product to Mac OS X - until Panther came out and stole some of its thunder. For a few dollars more ($30), it not only does what this, Preview and Acrobat does, but allows you to insert text into PDF files, such as to fill out forms. That IS something none of the rest do.

I would buy this product, if it could open multiple .ps files at once (like MacGSview)

Slow, antique non-standard interface but it does the job.

I don't understand the anonymous attacks either, and I also don't understand why you wouldn't want it for OS-X. This code works great.
