Description

System.DllNotFoundException: Unable to load shared library 'libSystem.Security.Cryptography.Native.Apple' or one of its dependencies. In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable:

dlopen(???/dotnet-sdk/shared/Microsoft.NETCore.App/8.0.0-rc.1.23419.4/libSystem.Security.Cryptography.Native.Apple.dylib, 1): Library not loaded: /System/Library/Frameworks/CryptoKit.framework/Versions/A/CryptoKit

macOS Mojave 10.14.6

Reproduction Steps

Use System.Security.Cryptography.MD5.Create(); in macOS Mojave 10.14.6.

Expected behavior

Same as .Net 7.0, can be used normally.

Actual behavior

macOS Mojave 10.14.6

.NET 8 requires macOS 10.15 or later.

macOS 10.14 does not include the CryptoKit library that .NET 8 uses for cryptography purposes.

[zhenlinyang]

Starting from .Net Core 3.1, .Net requires macOS10.15+. But until .Net 7, it can run normally on macOS 10.14. And SDK 8.0.100-rc.1 Installer can be installed on macOS10.14.
Starting from macOS10.15+, macOS no longer supports 32-bit software, which makes projects that rely on 32-bit tool chains unable to run. Therefore, there are a large number of devices that have stopped updating to macOS 10.14 and will no longer be upgraded.
.Net 8 is an important LTS version, so I recommend that .Net 8 be compatible with macOS 10.14.

Thanks.

[vcsjones]

The installer should be blocking installation on 10.14. Are you saying that you were able to run the pkg installer on 10.14 and it did not block installation?

runtime/src/installer/pkg/sfx/bundle/shared-framework-distribution-template-x64.xml

Line 10 in f21a266

<os-version min="10.15" />

I recommend that .Net 8 be compatible with macOS 10.14.

Making 10.15 the minimum allowed solving numerous challenges to help .NET gain support for some cryptographic primitives without a dependency on third party software.

Additionally, it is far too late in the .NET 8 release cycle to consider undoing those changes.

[zhenlinyang]

Yes, I can run 8.0.100-rc.1 pkg installer on macOS 10.14.6, it did not block installation, and the installation was successful. I can even get this to run fine without using a library that doesn't exist.

[vcsjones]

I see. I think the problem is here:

https://github.com/dotnet/installer/blob/a382864dae552097c5a3245bcbf92d226f3d1fe9/src/redist/targets/GeneratePKG.targets#L98

The installer says 10.13 is the minimum here. @akoeplinger should we be bumping this version in the installer to 10.15?

[akoeplinger]

Yes, we do set the min macOS version in dotnet/runtime here which affects e.g. the standalone shared framework .pkg:

runtime/Directory.Build.props

Line 67 in f21a266

<macOSVersionMin>10.15</macOSVersionMin>

I'll send a PR to installer to fix this there too.
