I haven’t tried the latest version of MacOS, but I know in the past that I haven’t had an issues in reading a RAW file on MacOS. Let me give it a try and get back to you. It may not be right away.

Using .NetStandard 2.0 nuget packages version 5.0.0.71 from this repo I can't read RAW files on MacOS.
Try creating a reader and getting any information. The file error information reported by the reader is not informative (code 2). So I installed a FirstChanceException handler (https://docs.microsoft.com/en-us/dotnet/framework/app-domains/how-to-receive-first-chance-exception-notificationshttps://urldefense.proofpoint.com/v2/url?u=https-3A__docs.microsoft.com_en-2Dus_dotnet_framework_app-2Ddomains_how-2Dto-2Dreceive-2Dfirst-2Dchance-2Dexception-2Dnotifications&d=DwMCaQ&c=q6k2DsTcEGCcCb_WtVSz6hhIl8hvYssy7sH8ZwfbbKU&r=1W0yYkGl-IRzjDS5xSAn50se4hwvRVAdrlUA7-lc4w0&m=kncXSojhfjpHbDOmv7b8HbHksWsIzC9J_d0Bvtys_AfOcg4GL01IAVieGkiHTEZC&s=jK6HDenZpse3QnnKj-TAGMg4i65qmbkWg-_R-d8XQmk&e=):
AppDomain.CurrentDomain.FirstChanceException += (_, e) => {
Console.WriteLine($"FirstChanceException event #{Interlocked.Increment(ref _firstChanceCount)}" +
$"\tType: {e.Exception.GetType().Name}\n" +
$"\tSource: {e.Exception.Source}\n" +
$"\tMessage: {e.Exception.Message}");
};And the output is:
FirstChanceException event #1 Type: PlatformNotSupportedException
Source: System.IO.MemoryMappedFiles
Message: Named maps are not supported.FirstChanceException event #2 Type: NullReferenceException
Source: ThermoFisher.CommonCore.RawFileReader
Message: Object reference not set to an instance of an object.FirstChanceException event #3 Type: TargetInvocationException
Source: System.Private.CoreLib
Message: Exception has been thrown by the target of an invocation.FirstChanceException event #4 Type: NUnitException

Message: RethrownSo looks like there's some issue with memory mapped files. But it all works fine on Linux. I guess, should be working on MacOS as well.
The stacktrace does show that it's somewhere in RawFileLoader's constructor. I didn't understand what the error was about at first, and then read that named memory mapped files are a windows-only feature. However, at the same time, the reader works fine on Linux. Can it be that this constructor has some Windows-specific code path that is erroneously being taken on Mac, but some other code path is taken when running on Linux?
