Connecting a MacBook with an IFP should be a smooth process, but most people tend to have problems with enabling the touch feature or transferring the audio to the IFP.

Before You Start： Check Your Ports: (Avoid 90% of Connection Failures)

Before grabbing a cable, identify your hardware ports. Matching your Mac to the right IFP input is the secret to a successful setup.

On Your Mac: USB-C / Thunderbolt: Found on all modern MacBooks.

HDMI: Found on older models or the latest 14″/16″ MacBook Pros.

On the IFP (The Panel):

  • HDMI: For Video/Audio only.
  • USB-B (Touch): Usually a square-shaped port labeled “Touch.”
  • USB-C: A high-end port that handles everything in one go.
Connection MethodCables RequiredTouch Support
HDMI + USB-B2 CablesYES
USB-C (One-Cable)1 CableYES
Wireless (AirPlay)NoneUsually NO

Method 1: USB Wired Connection (Most Reliable, Touch Supported)

Step 1: Connect Cables (Order Matters)

  1. Turn off Mac and IFP.
  2. Choose connection:
  3. One-cable (new Mac): USB-C 3.1/Thunderbolt cable (direct connection, full function);
  4. Traditional: USB-C to USB-B (touch) + HDMI (video).
  5. Connect USB-C to USB-B (Mac → IFP “Touch” port) and HDMI (Mac/adapter → IFP HDMI port).
  6. Turn on IFP first, then Mac (aids detection).
  7. No display? Manually switch IFP input to HDMI/Type-C.

Step 2: Set Up Mac Display

  • Mac: Apple menu → System Settings → Displays.
  • No detection? Click “Detect Displays” at the bottom.
  • Select IFP → “Optimize for: [IFP Name]”.
  • Set resolution to 1920×1080; adjust “Scale” if blurry.
  • Check “Mirror Displays” (presentations) or uncheck (extended desktop).

Step 3: Enable Touch Function

  1. Mac: System Settings → Privacy & Security → Accessibility.
  2. Unlock → Check “USB Touch Interface” or IFP brand name.
  3. Not listed? Unplug USB, wait 10s, replug.
  4. Test touch: Tap IFP (cursor moves); if not, replug USB/change port or check drivers.

Mistake to Avoid: USB-C to USB-A won’t work for touch—use USB-C to USB-B.

Common Issues (Wired Connection)

Mac not detecting the display

  1. Check if the cable is securely connected
  2. Go to Displays and click “Detect Displays.”
  3. Try a different cable or adapter

The display is showing, but the touch is not working

  1. In 90% of cases, the USB touch cable is not connected

What if your Mac only has USB-C ports?

  1. Use a USB-C to HDMI + USB adapter
  2. Or connect via a full-featured USB-C cable (recommended)

Method 2: Wireless Connection (No Cables, For Presentations)

Option A: AirPlay (Native Mac, Easiest)

  1. Connect the Mac and IFP to the same 5GHz Wi-Fi.
  2. Mac: Control Center → Screen Mirroring.
  3. Select your IFP from the list; enter PIN if prompted (on IFP screen).
  4. To stop: Screen Mirroring → Turn Off Screen Mirroring.
  5. Wireless Notes: Wireless connection usually does not support touchback; slight lag may occur, especially with poor Wi-Fi.

Option B: EShare (For Sharp/AVer IFPs, Fixes AirPlay Glitches)

  1. IFP: Apps → EShareServer (note URL).
  2. Mac: Browser → Enter URL → Download/install EShare for macOS.
  3. Open EShare → Connect to Wi-Fi → Select IFP.
  4. Click “Share Screen”; enable touchback in settings if needed (official apps support this).
  5. To stop: Click “Stop Sharing” in EShare.

Quick Touch Calibration (If Inaccurate)

  1. Mac: System Settings → Displays → Select IFP.
  2. Click Advanced → Calibrate Touch → Tap each crosshair slowly.
  3. Click “Done” → Test touch again.

Common Issues (Wireless Connection)

Can’t find the device

  1. Make sure your Mac and the IFP are on the same Wi-Fi network
  2. Restart both the IFP and your Mac

Screen mirroring is lagging

  1. Switch to a 5GHz Wi-Fi network
  2. Disconnect other devices using the same network

AirPlay not showing up

  1. Make sure the IFP supports AirPlay
  2. Check that AirPlay is enabled on the panel

Still can’t connect?

Try using the manufacturer’s screen-sharing app instead

3 Tips to Make it Actually Work

1. Enable “Screen Recording” Permissions

  • This is the #1 reason wireless touch fails on Mac.
  • Go to System Settings > Privacy & Security > Screen Recording.
  • Toggle ON for your casting app (e.g., EShare). Without this, the IFP cannot “see” or control your screen.

2. Fix the “No Sound” Issue

If the sound is still coming from your laptop:

  • Click the Sound icon in your Mac’s menu bar.
  • Switch the Output device to the name of your Interactive Display.

3. Adjust for the Best View

If the image looks blurry or the icons are too small:

  • Go to System Settings > Displays.
  • Select the IFP and choose “Scaled” to find the resolution that fits the large screen best.
