Apple has pushed out GarageBand 6.0.4, introducing a few minor changes in addition to the usual “overall stability and performance” fixes. Of note, GarageBand’s Lesson Store has been changed to fix an issue that was preventing lesson downloads from completing properly. On a more practical note, the update also addresses a bug that caused some tempo-based effects to fall out of sync with the main song, as well as a problem with Magic GarageBand projects not opening properly in the tracks view. ($14.99 new from the Mac App Store, free update through Software Update or the Mac App Store, 53.72 MB)
Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.
