A:
1. Disable Time Machine: Go to the Time Machine pane of System Preferences, then set the switch to Off and close System Preferences.
- Kill the syslogd process: Launch Activity Monitor (in /Applications » Utilities), find and select syslogd, and click Quit Process. You will need to authenticate.
At this point, the process should restart, but the CPU usage should be next to nothing.
B:
fire up Terminal and execute the following commands (enter administrator password when asked):
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Now reboot your Mac and everything should be fine!
