Option-Click AirPort Menu for Network Details

If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.

Safari 3.2 Fixes Security Flaws

Send Article to a Friend

Apple has released Safari 3.2, which addresses a host of vulnerabilities, mostly in the version for Windows XP and Vista. A full rundown of changes is found in the security note. Most of the flaws relate to image handling and parsing under Windows. Several fixed bugs are cross-platform, and, among other improvements, close holes that could allow disclosure of information in forms to unintended users. In particular, Safari adds anti-phishing protection using Google's list of suspected malicious sites.

Most surprisingly, the Windows version of Safari was using zlib 1.2.2, an open-source library of compression algorithms designed to avoid stepping on (and being encumbered by) any patents. The 1.2.3 release came out in July 2005 to fix known flaws in the previous release. Someone was apparently asleep at the switch in using the older library. zlib was likely used in handling compressed Web pages, an option that many servers employ to reduce the time spent and bandwidth used in transmitting HTML.

Safari 3.2 can be automatically updated through Software Update under Mac OS X or Windows with Safari installed. The new release may also be downloaded separately for Mac OS X 10.4 Tiger (25 MB), Mac OS X 10.5 Leopard (39 MB), or Windows XP/Vista (19 MB).
