### Step 0

Reboot into Recovery OS + Disable SIP
```
csrutil disable
```

### Step 1

```
# Remove IDEModelAccessOnDeviceAvailabilityOverride if you have watched my tweet before
defaults delete com.apple.dt.Xcode IDEModelAccessOnDeviceAvailabilityOverride
```

```
# Clear old eligibilityd cache
sudo rm -rf /private/var/db/eligibilityd
# Lauch Xcode to tirgger a new record
/Applications/Xcode-16.0.0-Beta.app/Contents/MacOS/Xcode
```

Use vim in terminal or VSCode to change eligibility.plist (Need root permission)

```
sudo vim /private/var/db/os_eligibility/eligibility.plist
# Go to OS_ELIGIBILITY_DOMAIN_XCODE_LLM field
# The normal value are 1, 2, 3, 2
# You need to change them to 1, 4, 3, 3 
```

> For the meaning of the numbers, you can check out https://x.com/KyleSwifter/status/1802405373133099475 or eligibilityd repo which I will open source later.

### Step 2

Lock the `eligibility.plist` file to prevent `eligibilityd` changing it again.

1. `cd /private/var/db/eligibilityd && open .`
2. ⌘+I on `eligibility.plist` file
3. In `Sharing & Permissions` section, unlock and then set system's privilege to "Read only" too.

### Step 3

Reboot and open Xcode. That's all. Done.

> Click the "Predictive code completion" on Xcode and then it will tirgger a popup to download the LLM model.
