After the recent and unplanned `fork` users need to upgrade to SYRIUS v0.0.7.
First, download the latest SYRIUS release: [Releases · zenon-network/syrius · GitHub](https://github.com/zenon-network/syrius/releases) If your sync gets stuck, follow these instructions:
* * *
**macOS Users**
1. **Close Syrius.**
2. **Open Finder.**
3. Press `⌘ + shift + H` to go directly to your _Home_ folder.
4. Now press `⌘ + shift + period (.)` to make the hidden _Library_ folder visible.
5. Navigate to the `Library/znn` folder.
6. Once you’re inside the folder, either **delete** or **rename** these directories: _nom_, _consensus_, and _network_.
7. **Launch Syrius**. It should now begin to re-sync.
* * *
**Windows Users**
1. **Close Syrius**
2. Open the Windows Explorer and navigate to the following path:
`C:\Users\\AppData\Roaming\znn`
3. Inside this directory, you should see several folders. Either **delete** or **rename** these specific directories: _nom_, _consensus_, and _network_.
4. **Launch Syrius**. The application should start the re-syncing process from scratch.
* * *
Remember, always make sure to backup SYRIUS and/or make sure you seed phrase is ready and works as expected.

Issue happened with 0.0.7, didn’t improve with 0.1.0. Running znnd alone too didn’t work.

## Guide: Updating libznn.dylib for Syrius on macOS
Follow these steps to update the libznn.dylib file for the Syrius app on macOS. Ensure you have wget installed (e.g., via Homebrew with brew install wget).
BEFORE YOU START THIS PROCESS MAKE SURE SYRIUS IS STOPPED, NOT CLOSED, STOPPED.
1. Navigate to the Syrius Resources directory:
```auto
cd /Applications/Syrius.app/Contents/Resources
```
1. Rename the existing libznn.dylib to a backup file:
```auto
mv libznn.dylib libznn.dylib.bak
```
1. Download the latest libznn release:
```auto
wget https://github.com/zenon-network/go-zenon/releases/download/v0.0.8-alphanet/libznn-darwin-arm64.tar.gz
```
1. Extract the downloaded file:
```auto
tar -xvzf libznn-darwin-arm64.tar.gz
```
1. Rename the extracted file to libznn.dylib:
```auto
mv libznn-darwin-arm64.dylib libznn.dylib
```
