macOS crash on start

I get this: Could not load the file 'System.Runtime.CompilerServices.Unsafe'

Everything works in the version 0.26.

It is possible that it is a bug in Xamarin.Mac, as there are no problems in Xamarin.iOS but I would need some confirmation to submit it there.

Honesty, not really sure.

I'm unfamiliar with what library targets Xamarin.Mac would use. Must be NET Standard 2.0.

Looks like I updated to CodePages 5.0.0 with 0.27 but also added more Unsafe and memory/span usage.

I'm guessing Xamarin.Mac isn't updated as quickly as Xamarin.iOS. Hopefully, MAUI will fix a possible out of date issue.

I had the same error (Could not load the file 'System.Runtime.CompilerServices.Unsafe') on Windows, and in my case the problem was that I did not have the correct binding redirects. I guess Xamarin.Mac also relies on binding redirects the same way ?

As advised in the related issue on Xamarin Github I have installed System.Runtime.CompilerServices.Unsafe nuget and now it works. However it should work out of the box so possibly you should add this to the list of dependencies. My personal opinion is that this should come with Xamarin.Mac, but as they deny that I guess this should be the solution then.
