I've seen a new process that I'm not familiar with "coreduetd" taking 100% CPU on random occasions.
Anyone know what this new process is related to?
Googling didn't help much... must be something internal at Apple
"CoreDuet framework"
a 'ps' of the process in Terminal reveals..
45 ?? 167:45.39 /usr/libexec/coreduetd
It appears to use a fair bit of CPU compared to other processes.
