No. Attaching the USB-C Snap Hub to both USB-C ports on your MacBook Neo will not damage the ports, as long as you attach and remove the hub correctly. The dual USB-C connector is designed to fit standard USB-C ports and works best on a flat, level surface.

Follow these tips to protect your ports:

• Line up both connectors and insert the USB-C Snap Hub straight in, without twisting or pushing sideways.
• Take extra care when you travel or move around with the USB-C Snap Hub attached.
• Remove the USB-C Snap Hub when you are not using it.
• When you remove the hub, grip the body of the USB-C Snap Hub, not the laptop. Pulling from the laptop can put sideways force on the connectors and damage them.
