# macOS Groupware Synchronization

macOS Groupware Synchronization is the process of linking the native macOS Calendar and Contacts applications to the university's [[groupware]] server to ensure data consistency across devices.

## Technical Implementation

The synchronization relies on two standard protocols:
- **CalDAV**: For calendar appointments and schedules.
- **CardDAV**: For address book entries and contacts.

### Configuration Steps
To set up synchronization on macOS:
1. Navigate to **System Settings** $\rightarrow$ **Internet Accounts**.
2. Select **Add Other Account...**.
3. Choose either **CalDAV Account** (for calendars) or **CardDAV Account** (for contacts).
4. **Critical Step**: Set the **Account Type** to **"Manual"**.
5. Enter the university credentials (username and password).
6. Enter the server address: `groupware.uni-greifswald.de`.
7. Click **Create** and then **Sign In** (Anmelden) when prompted.

## Usage Guidelines and Limitations
- **Write Permissions**: It is strongly recommended to only synchronize calendars for which the user has read-write permissions.
- **Support**: If synchronization fails, users should contact the [[universitatsrechenzentrum-urz]] via the Groupware ticket system or the URZ hotline (ext. 1420).
