version extraction issue with macOS 15.5

[mabiede]

The Edf2Mat converter tries to load edfimporter_pre11 on the macOS 15.5 (on Apple Silicon).

• as the os version is '15.5' the toolbox shouldn't change the converter to be _pre11

Error message

Unrecognized function or variable 'edfimporter_pre11'.

Error in Edf2Mat>@(varargin)edfimporter_pre11(varargin{:}) (line 364)
                       importer = @(varargin)edfimporter_pre11(varargin{:});

                obj.processFile();

Workaround

There are two workarounds depending on how good you feel:

• Remove the version check on macOS (change the processFile function to the following):

      function processFile(obj)
          importer = @(varargin)edfimporter(varargin{:});
          if ~obj.oldProcedure  
              obj.RawEdf      = importer(obj.filename);
              obj.Header.raw  = obj.RawEdf.HEADER;
              obj.Samples     = obj.RawEdf.FSAMPLE;
          end
          
          obj.convertSamples();
          obj.createHeader();
          obj.convertEvents();
          if obj.verbose
              disp('Edf succesfully converted, processed.!');
          end
  
      end

• Change the OS version to hardcoded (see code line here)

  % from
  [~, version] = unix('sw_vers -productVersion');
  % to
  version = '15.5'; % your macOS version

Conclution

• Deprecation of automatic importer switch for old macOS.
• The functionality will be changed in future releases (may has to be forced via optional input argument).
