A co-worker got a brand-new MacBook Pro (w/ 10.7), and used Time Machine to restore their files/settings from their old MacBook Pro (w/ 10.6, upgraded from 10.5, probably upgraded from 10.4).
They ended up with a mess of nasty crap, like ancient HP drivers and Cisco VPN kexts in /System, messed up permissions, etc.
I removed the problem kexts that I could identify, and most permissions have been reset.
However, coreaudiod now pegs the CPU at 100%. The CPU fan is always spinning, the system is slow, etc. coreaudiod just restarts when we kill the process.
Any way to figure out what is messing up Audio? Old kext? browser plugin?
I saw a suggestion on another web site: just loading iTunes (and leaving it running in the background with nothing playing) seems to tame the process.
