From MaGog's logs for 26 March:

NOTE! Probably CHANGED FILE Master of Orion: Collector's Edition [In Dev], all_files, Mac OS X installer, English, dl_ver: 42 (gog-4) ***TO*** 42.6.0.5.1702 (gog-5)

[Complements the earlier Windows update.]

I have 5 languages to chose from in my library and also in GOG downloader listing (English, French, Italian, German, Spanish) so maybe I am looking at the wrong thing or Judas has already fixed the issue.

The Win version has them all - including a language selector to change between them.(Not able to test Linux - Judas to the rescue)

All three OS have all five languages languages listed in the GOG library drop-down menu.

However, in Windows and Linux all five languages point to the same file, a single multilingual installer, whereas in Mac they point to five different files, each a monolingual installer. This difference is what Loenas was asking about.

The way GOG presents its installers make it impossible to detect the difference without attempting to download the files. MaGog shows the difference more clearly, I believe:
[url=http://www.an-ovel.com/cgi-bin/magog.cgi?ver=722&scp=gdspurio&dsp=iD&ord=&flt=tcs~beneath+a+ste~&opt=n]http://www.an-ovel.com/cgi-bin/magog.cgi?ver=722&scp=gdspurio&dsp=iD&ord=&flt=tcs~beneath+a+ste~&opt=n[/url]
Win and Linux show one file (English+French+German+Italian+Spanish). Mac shows five.

Hope this clarifies the Judas-Loenas dialogue.

Ah, thank you for clearing this up. I only looked at the shown link and did not attempt to download the files.

From MaGog's logs for 27 March:

NOTE! CHANGED Wing Commander™ 3 Heart of the Tiger™, languages: Audio and text: English. Text only: German, French ***TO*** Audio and text: German, English. Text only: French

It was about time. The German dub for Wing Commander III is one of the best a German version of a game ever got.

Thank you, that's good to know! Sorry for the false alarm.
