What is liquiddetectiond?

liquiddetectiond is a process related to protecting your Mac from liquid damage.

What is liquiddetectiond?

liquiddetectiond watches sensors that detect liquid near your Mac's ports and internal parts. If liquid is found, it can take steps to prevent electrical damage.

What does it do?

When liquid is detected, the daemon can:

• Warn you that liquid has been found near the ports
• Stop charging or USB-C power delivery to prevent short circuits
• Log the event for later troubleshooting

This is similar to the liquid detection warnings that iPhones show when moisture is found in the USB-C port.

Which Macs have this?

Liquid detection sensors are found in newer Mac laptops. Not all Macs have this hardware. It depends on the model and generation.

Does it use a lot of resources?

No. It watches sensor data in the background and uses almost no resources.

Should you worry?

Not unless you get a liquid detection alert. If you do, unplug the power, dry the affected area, and wait before plugging back in. The daemon is protecting your Mac from electrical damage.
