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.

Retrospect 11

Send Article to a Friend

Retrospect Inc. has released Retrospect 11 for Mac, a major update to the backup software that’s used primarily by small and medium-sized businesses with mixed-platform networks. (In addition to the Mac update, Retrospect 9 for Windows was also released.) The big news for Retrospect 11 is that it adds a block-level incremental backup option, which should boost performance as it backs up only those portions of files that are modified since the previous backup. This option needs to be enabled in your backup scripts or in the backup wizard while using existing selectors or rules.

Retrospect also adds a new high-level dashboard, which provides a weekly backup summary and a visualization of recent backups to help identify storage usage and ensure complete data protection for your network. Additionally, the improved email reporting includes the operations log for a view into the complete details of your backup process. (For more details on these new features, see this What’s New overview at the Retrospect Web site.) Many bugs are also addressed, with version 11 fixing several intermittent cases of Past Backups not refreshing; correctly displaying server-specific changes when connected to multiple servers; correcting the days of the week in scripts for the German, French, and Italian localizations; and allowing the sorting of media sets that are in the Busy state.

Retrospect 11 pricing ranges from $119 for Retrospect Desktop (for a single non-server computer and up to 5 additional networked computers) to $499 (single-server with up to 20 workstation clients), all the way up to $2,199 (for multiple servers and unlimited clients). ($119–$2,199 new, $69–$1,299 upgrades, 362 MB, release notes)
