Postbox has released version 3.0.8 of its eponymous email client, using the integrated graphics processor exclusively on MacBook Pro models that have dual GPUs in order to reduce power usage and thus save some battery life. The update also adds a Run Filters on Folder toolbar button, ensures that Notification Center alerts link directly to messages, displays the account name next to the folder name in the message pane, and adds automatic account configuration support for iCloud email accounts. Plus, it fixes an issue with Growl integration, a crash when indexing, and a crash when importing from Thunderbird. ($9.95 new, free update, 21.5 MB, release notes)
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
