+The .Net 8.0 SDK is required. Install the correct version for your platform/architecture. On macOS, XCode 16.0 or later is required (install from the App Store).
+
+> ⚠️ macOS requires a specific version of the .Net SDK: 8.0.204, due to the .Net team forcing minos version of macOS 15 in later SDKs. If you only want to build for macOS 15 and up, you can use the latest SDK.

-### Building on Mac
-
-1. Download and install the [.NET 8.0 SDK (x64)](https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/sdk-8.0.204-macos-x64-installer) or [Apple Silicon (e.g. M1)](https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/sdk-8.0.204-macos-arm64-installer).
-    ⚠️ The latest .NET 8.0 SDK forces the minimum version of the compiled app to macOS 15 (sequoia). If this is not desired, use a prior version. 8.0.204 is a known working version.
-2. Install XCode from the [AppStore](https://apps.apple.com/us/app/xcode/id497799835?ls=1&mt=12)
-3. Run `dotnet build`
-
-#### Mac errors
-
-Problem: `error NETSDK1139: The target platform identifier macos was not recognized.`
-Solution: run the command `sudo dotnet workload restore EndlessClient/EndlessClient.csproj` which will install the macos workload for you.
+> Run: `dotnet format EndlessClient.sln`
