mac-gs problem

Hi everybody and happy new year.

I have a macintosh G4 under OSX.

For some reason that I do not understand, mac-gsview does not work on any
file. When reading the examples that come up with the installer, I get the
following message:

"This document does not conform to the Adobe Document Structuring
Convention. If you attempt to open it anyway, you will only be able to
page through the file's pages sequentially."

I checked whether the examples might have been corrupted at some point.
They are not, and they are postscript indeed. Let me be more precise:
two examples do not give me insulting messages, namely the golfer and the
tiger. So this sounds like bad management of the fonts.

If I try to view pages generated by printing to file on a virtual
postscript printer, I can't even open the file. The typical example is the
following: I write a file for a LaTeX paper under Textures in Classic. The
typeset is correctly displayed on screen. I print to a virtual printer.
The result does not open. Then, I resave the output under unix format
instead of macintosh, via alpha and the result opens under macgsview;
this time, the paper opens. however, not a single font is correctly displayed.

I first thought that Textures was guilty, so that I got another
implementation of TeX. (1) the other implementation of TeX works fine (2)
Illustrator is very happy to open the first page of the Textures generated
file, in both formats, macintosh and unix.

macgsview used to work fine under OS9. I upgraded to 9.2.2 and then to
OSX, and it became unusable, be it under classic or under macOS.

Any idea of the origin of this problem?

Thank you for your attention.
