 ### Demoting `x86_64-apple-darwin` to Tier 2 with host tools

-In accordance with these changes, the Rust project is in the [process of demoting the `x86_64-apple-darwin` target][rfc] from Tier 1 to Tier 2 with host tools. This means that the target, including tools like `rustc` and `cargo`, will be guaranteed to build but is not guaranteed to pass our automated test suite.
+In accordance with these changes, the Rust project is in the [process of demoting the `x86_64-apple-darwin` target][rfc] from [Tier 1 with host tools](https://doc.rust-lang.org/stable/rustc/platform-support.html#tier-1-with-host-tools) to [Tier 2 with host tools](https://doc.rust-lang.org/stable/rustc/platform-support.html#tier-2-with-host-tools). This means that the target, including tools like `rustc` and `cargo`, will be guaranteed to build but is not guaranteed to pass our automated test suite.
 
 We expect that the RFC for the demotion to Tier 2 with host tools will be accepted between the releases of Rust 1.89 and 1.90, which means that Rust 1.89 will be the last release of Rust where `x86_64-apple-darwin` is a Tier 1 target.
 
-For users, nothing will change. Builds of both the standard library and the compiler will still be distributed by the Rust Project for use via `rustup` or alternative installation methods.
+For users, this change will not immediately cause impact. Builds of both the standard library and the compiler will still be distributed by the Rust Project for use via `rustup` or alternative installation methods while the target remains at Tier 2.
