What is iomfb_bics_daemon?

iomfb_bics_daemon is part of the IOMFB (IO Mobile Framebuffer) display system. "BICS" relates to the built-in colour and brightness calibration. The daemon manages display calibration data so that your screen colours and brightness stay accurate.

What does it do?

• Loads and applies display calibration profiles
• Manages brightness and colour temperature data for the built-in display
• Supports True Tone (adjusting white balance based on the light around you)
• Keeps colours accurate across different brightness levels

Why is it called "mobile"?

The IOMFB framework started on iOS (hence "Mobile Framebuffer") and came to macOS with Apple Silicon, which shares much of its display system with iPhone and iPad. Despite the name, it is the standard display system on Apple Silicon Macs.

Does it use a lot of resources?

No. It loads calibration data and applies it. This is light, ongoing work.

Should you worry?

No. It is a standard display process on Apple Silicon Macs that helps keep your screen looking right.
