Crossplat demo does not work on Mac

When I run it, I've got crash in libcef.dylib, last messages in terminal are

@xplicit the reason you are seeing what you are seeing is because of the CEF download process. There seems to be a timing issue between the actual application run and CEF download process. Seems like the app timesout waiting for the download to complete.

After the error and a successful CEF download, run it again:

dotnet run

[xplicit]

Yeah, It's working, if start again.

I workarounded that by setting FrameworkDirPath in chromely source and placing CEF binaries during build into output folder.

            var settings = new CefSettings
            {
                MultiThreadedMessageLoop = _config.Platform == ChromelyPlatform.Windows,
                LogSeverity = CefLogSeverity.Info,
                LogFile = "logs\\chromely.cef_" + DateTime.Now.ToString("yyyyMMdd") + ".log",
                ResourcesDirPath = Path.Combine(_config.AppExeLocation, "Resources"),
                FrameworkDirPath = _config.AppExeLocation
            };

Can we add the ability to override CefSettings which are used in HostBase from user code? I see there is a extension method to update them from string dictionary, but it does not contain all settings , for example, FrameworkDirPath is not in the dictionary. It would be simper to path the settings from the object, because in this case we can see all available properties from IDE

[xplicit]

If run with command dotnet run it works. If change directory to bin folder and run crossplatdemo binary from that folder it shows error message about icudtl.dat file (even when CEF files downloaded). If set FrameworkDirPath = _config.AppExeLocation it also works when run binary from bin folder.

Apple M1 heads up

On Apple Silicon, it is required to use <RuntimeIdentifier>osx-x64</RuntimeIdentifier> or build with dotnet run -r osx-x64, or you will get the same error (icudtl.dat not found in bundle).

On Intel Mac, it used to work fine without explicit runtime identifier.

[daedalus-codes]

I'm encountering this on an Intel Mac and no matter what I do, I cannot seem to get it to work... with dotnet run or attempting to set the custom CefConfiguration settings i.e. Framework Dir. It's very frustrating!

[wwarby]

I'm still experimenting with this, but as a first step I tried running every single demo app on Mac OS. None of them worked, but the variety of different ways in which they failed was impressive :) For further testing, which ones would you expect to work out-of-the-box?

Here are my results:

In my own app I additionally managed to generate a The cache_path directory (/usr/share/MyAppName/chromely-cache) could not be created. error somehow.

I'm going to concentrate on the Angular scenario, since that's what my app is, and I've fixed the superficial issues that cause it to not build out-of-the-box and now I get the same results in the demo app (more or less) as I do in my own app. I'm not clear from this thread though what the solution is. Running it a second time seems to be the proposed solution - that definitely doesn't work in my case.

@wwarby sorry I was not really monitoring this issue since it was closed, but just seeing this. Please let me know if yo still need some inputs, Thanks.
