In conjunction with the announcement of the iPhone 5 and new iPod models, Apple has released iTunes 10.7 to add support for iPhone, iPad, and iPod touch models running iOS 6 (scheduled for release on 19 September 2012). Additionally, it adds support for the latest iPod nano and iPod shuffle models. With no new features, iTunes 10.7 is just a compatibility stopgap until the next major release of iTunes appears in October. (Free, 157.33 MB via direct download or 163.3 MB via Software Update)
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.
