@davidortinau was testing .NET 8 preview 1 builds and hit the error:

We found that running this fixed it:
chmod +x /usr/local/share/dotnet/packs/Microsoft.NETCore.App.Runtime.AOT.osx-x64.Cross.maccatalyst-x64/8.0.0-preview.1.23106.5/tools/mono-aot-cross
The Android/iOS workloads define a data/UnixFilePermission.xml file, so that dotnet workload commands can supply the execute bit. Details at: dotnet/sdk#16894
We think this was implemented sometime in dotnet/runtime: #54501
But I don't see the file here:
Reproduction Steps
- Install .NET 8 Preview 1 MAUI bits: https://gist.github.com/jonathanpeppers/99961b4639823206c2537c03c856b097
dotnet new maccatalystdotnet build
Expected behavior
You should not need to chmod +x mono-aot-cross
Actual behavior
Some Mac machines you have to chmod +x mono-aot-cross.
Regression?
Yes
Known Workarounds
chmod +x /usr/local/share/dotnet/packs/Microsoft.NETCore.App.Runtime.AOT.osx-x64.Cross.maccatalyst-x64/8.0.0-preview.1.23106.5/tools/mono-aot-cross
Configuration
.NET SDK 8.0.100-preview.1.23109.10
