You can share your MacBook screen wirelessly to an i3 ELM 2 classroom screen using **i3 AllSync** or Apple’s built-in **Screen Mirroring**.

## Before you start

- Turn on the i3 screen.
- Make sure that your MacBook is connected to the ISB network. The classroom screen should be connected to Touchscreen.
- Make sure the screen is showing the AllSync presentation screen.
- Do not share confidential information with the wrong classroom display.
  
## Start sharing

1. On the i3 screen, open the **Present** or **AllSync** tile.
2. On your MacBook, open **Control Center** from the menu bar.
3. Select **Screen Mirroring**.
4. Select the classroom i3 screen.
5. Enter the four-digit PIN shown on the i3 screen, if requested.
6. Your MacBook screen should now appear on the i3 screen.

## Stop sharing

1. Open **Control Center** on your MacBook.
2. Select **Screen Mirroring**.
3. Select **Stop Screen Mirroring**.


## If it does not work

- Confirm that the AllSync presentation screen is open.
- Check the PIN carefully.
- Turn Screen Mirroring off and on again.
- Restart the AllSync app.
- Contact IT and include the classroom number and MacBook name.

## Important

Wireless presentation is best for slides, documents, and short demonstrations. For long videos, use a cable or the Windows module/input.
