Firmware Update Solves Power Mac G5 1.8 GHz Freezes -- Last week, a reader wrote in asking if we knew anything more about the freezing problems he was having with his single processor Power Mac G5 1.8 GHz. Almost simultaneously, Apple released a firmware update for that machine that promises to address a number of freezes, enabling us to write back and tell him that we'd looked into the problem, contacted Apple, and that they had dropped everything to release a firmware update for us. Every now and then you just have to take credit for utter coincidences! There are separate updates for Mac OS X 10.3.9 and 10.4.3; they're about 1 MB in size. [ACE]
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.
