After golden gate update rewrite is not working

It is unclear what you mean. Please see the following, a post that is confusing does not typically result in helpful replies.

It sounds like you mean a 3rd party app of some sort. There is an iPad app of that name:

If you are talking about a 3rd party app, and that app is not compatible with macOS 27 Golden Gate, then you need to contact the developer and they need to update the app.

I'm having an issue with Apple's native Writing Tools feature. The Rewrite option worked fine before the recent update, but now it fails. When I select a line of text, right-click, choose Show Writing Tools, and then click Rewrite, I get the following error:

The "Writing Tools Unavailable" error on Apple Intelligence happens when your device has a language mismatch, an unfinished AI model download, or a disrupted network connection.

How to Fix the Error

• Match your language settings: Make sure your device language and Siri language are set to the exact same supported language (such as English - U.S.) in your system settings.
• Turn off your VPN: Active VPNs or strict work profiles can block Apple's servers from downloading or verifying the AI models. Disable your VPN and try again. 
• Check Apple Intelligence download progress: Go to System Settings > Apple Intelligence to confirm the feature is turned on and any background model downloads have finished. 
• Restart your device: A simple reboot often clears temporary cache or API bugs preventing the tool from loading

If the above does not help, then see if the problem is present when you boot in safe mode. That process performs some system cleanup and clears caches, and also disables 3rd party extensions that may cause problems.

If that does not correct the issue, test in a new user account. A newly-created user account will have all settings at default, and if the issue does not occur in that new account then it provides guidance on what may need to be changed to correct the issue.

Once the testing is complete, the new account can easily be deleted.

Those steps will help to isolate the problem.

Thanks for clarifying the problem you are having.
