+# zouxian 走线
+
+Apple restricted the access to Xcode LLM (Predictive Code Completion) feature on China models of Mac. That is, if you are using a Mac bought in China, even if you are not in China, you will not be able to use Predictive Code Completion. 
+
+If you are unfortunate to be in this situation, now it is time take your Mac on a journey of _[Zouxian](https://en.wikipedia.org/wiki/Zouxian_(phenomenon))_.
+
+---
+
+Persistent solution after rebooting, based on [unixzii's guide](https://gist.github.com/unixzii/6f25be1842399022e16ad6477a304286). Verified on macOS 15.0 Beta (24A5264n), but there is no guarentee that it will always work on later macOS versions.
+
+# Prerequisites
+
+* Xcode is installed and run at least once.
+* SIP debugging restrictions are disabled (via `csrutil enable --without debug` command in recovery mode).
+
+# Disclaimer
+
+Disabling SIP can cause some unknown effect. And for now, Xcode LLM is not stable and may cause kernel panics, which will lose some of your document modifications. **Please use with caution.**
+
+# Install
+
+```powershell
+brew install catme0w/tap/zouxian
+sudo brew services start zouxian
+```
+
+> Check out [the formula](https://github.com/CatMe0w/homebrew-tap/blob/main/Formula/zouxian.rb) if you're interested
+
+# Uninstall
+
+```powershell
+sudo brew services stop zouxian
+brew uninstall zouxian
+```
