In a statement to Gizmodo, Apple publicly acknowledged the vexing display issues plaguing its latest iMac models. The symptoms of these issues, which mostly affect the 27-inch model, include yellow discoloration and screen flickering. In its statement Apple said, "We've addressed the issues that caused display flickering and yellow tint. Customers concerned that their iMac is affected should contact AppleCare." While the company has been too slow in addressing this problem, better late than never. follow link
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.
