I had extracted the files from the CD multiple times using Cider Press 1, Cider Press 2 and also the ScummVM Dumper Companion. The game is always recognised, no problem with that. But then I always received the following message upon starting the game in ScummVM "Could not find the "Full Throttle" Macintosh executable to read resources from. The Mac GUI will be disabled."
Here is my solution:
On the German language Mac CD of Full Throttle two files are named named differently hence to the German title ("Vollgas") of that game.
The files mentioned in the wiki need to be renamed after extraction: rename 'Vollgas Data' to 'Full Throttle Data' and 'Vollgas' to 'Full Throttle'
https://wiki.scummvm.org/index.php?title=Full_Throttle
Then ScummVM will be able to run the German language version of Full Throttle (Mac) with the Mac GUI and respective menus.

Btw. I always use the daily build (latest branch master).
P.S.: There is a typo on the mentioned wiki page. One file not necessary for the PC demo version is listed as 'lidtsaw.san', but in fact it is named 'liftsaw.san'.
