## Troubleshooting

As Jan is in development mode, you might get stuck on a broken build.

To reset your installation:

1. **Remove Jan from your Applications folder and Cache folder**

   ```bash
   make clean
   ```

   This will remove all build artifacts and cached files:

   - Delete Jan from your `/Applications` folder
   - Clear Application cache in `/Users/$(whoami)/Library/Caches/jan`

2. Use the following commands to remove any dangling backend processes:

   ```sh
   ps aux | grep nitro
   ```

   Look for processes like "nitro" and "nitro_arm_64," and kill them one by one with:

   ```sh
   kill -9 <PID>
   ```
