Apple restricted the access to Xcode LLM (Predictive code completion) feature on China models of Mac. This guide provides a way to bypass that restriction. It's verified on macOS 15.0 Beta (24A5264n), but there is no guarentee that it will always work on later macOS versions.
- Xcode is installed and run at least once.
- SIP debugging restrictions are disabled (via
csrutil enable --without debugcommand in recovery mode).
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.
1. Attach to eligibilityd using LLDB
$ sudo lldbThen execute the below command in LLDB console:
(lldb) process attach --name eligibilityd
It should stop the main thread of eligibilityd process and show a (lldb) prompt if successful.
2. Modify the device region
(lldb) e (void) [[[InputManager sharedInstance] objectForInputValue:6] setValue:@"US" forKey:@"_deviceRegionCode"]
3. Recompute the domain answers
(lldb) e (void) [[EligibilityEngine sharedInstance] recomputeAllDomainAnswers]
4. Verify the domain answer (Optional)
You can check whether the operation is effective by executing:
(lldb) po [[[[EligibilityEngine sharedInstance] domains] objectForKey:@"OS_ELIGIBILITY_DOMAIN_XCODE_LLM"] answer]
If it prints 0x0000000000000004 then it's all good.
5. Detach the process and exit LLDB
(lldb) process detach
(lldb) exit
6. Restart Xcode and enjoy!
Thanks for those who make this possible together: Lakr233, Sou1gh0st, Yuriko.
it works like a charm, cheers
