colorsync.display high cpu

Question

PID 217, colorsync.display is pegged at 119% CPU, any ideas what this is or what might be causing it?

EDIT: It is happening again

EDIT EDIT (12/27/2019): Happening again with no cause known yet...

EDIT EDIT EDIT (2/2/2020): Happening again, any ideas?

There is no process in Activity Monitor showing that kind of CPU usage

Was the sample taken when it was running high? The screenshot shows 0.0 CPU%. Colorsync is part of MacOS's graphics system that ensure accurate or consistent colors. Why it's pegging a core is unknown here. — benwiggy, Commented Dec 24, 2019 at 13:06
That is just it, In htop or top it shows a pegged core, in activity monitor, 0% — Jeffrey L. Roberts, Commented Dec 27, 2019 at 7:50

I experienced the same today on a 2019 13-inch MacBook Pro. I only saw the process in htop with high CPU usage stuck at the same value for several minutes, but not showing in Activity Monitor. I quit and started htop again and it appears to be gone. If I filter for colorsync it shows a number of processes, among them colorsync.display, with CPU usage at 0%.

This may just be a process that gets stuck in htop for some reason.

Update 24th of February 2021: experienced the same on a M1 MacBook Air. Restarting htop removed it from the top CPU-consuming processes listed there.

The same happened to me. After rerunning htop the process with name colorsync.displa disappeared.

This looks like an htop bug - same issue and workaround on macOS 10.13

I'm experiencing the issue, and in my case, the high CPU usage is reported by both Activity Monitor, and iStat Menus.

Commented Nov 13, 2023 at 10:09
@Cykelero is it persistent or does it disappear when restarting Activity Monitor or iStat Menus?
– dniviE
Commented Nov 14, 2023 at 11:04
@dniviE Definitely persistent—restarting the apps doesn't make it go away. top reports it too. In my case, the issue seems triggered by specific apps. (Nova and Sketch)

If you use Activity Monitor, you can select the process and Inspect Process CommandI. The click on the "Open Files and Ports" tab.

That will show you all the files that the process is using, but the most relevant files should be at the top of the list.
