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.
