For those who want to read and write preferences for a macOS application, this can be done using the following methods:
| CODE FOR READING PREFERENCES |

uses MacOSAll, CFPreferences;
var
IValid: Boolean;
Pref: Integer;
procedure TForm1.FormCreate(Sender: TObject);
begin
try
Pref := CFPreferencesGetAppIntegerValue(CFStr('Check1'),kCFPreferencesCurrentApplication,IValid);
if (Pref = 1) then
begin
CheckBox1.Checked := true;
end
else begin
CheckBox1.Checked := false;
end;
Pref := CFPreferencesGetAppIntegerValue(CFStr('Check2'),kCFPreferencesCurrentApplication,IValid);
if (Pref = 1) then
begin
CheckBox2.Checked := true;
end
else begin
CheckBox2.Checked := false;
end;
Pref := CFPreferencesGetAppIntegerValue(CFStr('Check3'),kCFPreferencesCurrentApplication,IValid);
if (Pref = 1) then
begin
CheckBox3.Checked := true;
end
else begin
CheckBox3.Checked := false;
end;
Pref := CFPreferencesGetAppIntegerValue(CFStr('Check4'),kCFPreferencesCurrentApplication,IValid);
if (Pref = 1) then
begin
CheckBox4.Checked := true;
end
else begin
CheckBox4.Checked := false;
end;
except
on E : Exception do
ShowMessage(E.ClassName+' error raised, with message : '+E.Message);
end;
end;
