#14843: MacResManager: don't look for files outside game folder
--------------------+---------------------------
Reporter:  mikrosk  |      Owner:  (none)
    Type:  defect   |     Status:  new
Priority:  normal   |  Component:  Common
 Version:           |   Keywords:  macresman,mac
    Game:           |
--------------------+---------------------------
 This has been shortly discussed in June 2023 when I was seeing hundreds of
 the  "directory exists" messages related to "_ _MACOSX" handling. Then I
 found --disable-detection-full flag for ./configure which silenced them
 (because most of the Mac games aren't supported on Atari backend) and
 forgot about it.

 However today I was reminded about the issue again when I had my games on
 one (faster) disk while scummmvm executable would be on another (slower)
 one and adding Dreamweb game with hundred files.

 Back then, @criezy commented:

 ''Because it uses SearchMan by default, which include the path provided by
 the backend through OSystem::addSysArchivesToSearchSet(). This allows
 finding files that may not be in the game dirs (for example the engines
 data files provided with scummvm).''

 ''But you have an overload (MacResManager::open(const Path &fileName,
 Archive &archive)) that you can use to provide a SearchSet other than
 SearchMan.''

 ''But I am indeed not sure the default of using SearchMan is a good one
 for the MacResManager. I would not expect to have mac files outside the
 game folder in normal circumstances.''
