Here are some of the most significant bugs from the past week in the BugBlog:

Apple has a firmware update for MacBooks. The MacBook SMC Firmware Update v1.1 is supposed to fix some bugs that were causing unexpected shutdowns, otherwise known as crashes. You'll need to be updated to Mac OS X 10.4.8 to be able to see the SMC Update. Find out more here.

Daylight Savings Time starts earlier this year. Any software, such as your operating system, that automatically does the "spring ahead, fall back" may not be able to handle the change. Microsoft has a February 2007 cumulative time zone update for Microsoft Windows that will make the adjustment. Follow the link to the patch for your version of Windows.

The encryption that Windows Vista uses for communicating with secure web pages via SSL (Secure Socket Layers) is not compatible with the encryption used by Cisco PIX 515E firewalls. Try to use Internet Explorer 7 on Vista from behind one of these firewalls, and you may see this error message with secure pages: Internet Explorer cannot display the webpage. Microsoft says the Cisco firewall can only use the weaker DES. They have a workaround that weakens security. They also prod Cisco on that page to provide an update.
