Apple has released Mac OS X 10.7.5 Lion Server with fixes for a variety of commonly used services. The update provides fixes for maintaining the Spotlight index when changing share point settings, creating and connecting to the Open Directory master, using Software Update, and using Profile Manager to set how frequently the Mobility sync interacts with mobile accounts. It also improves the reliability of password authentication and changing an Xsan metadata controller into a client. The updates come in two editions — a delta update for those upgrading from 10.7.4 Lion Server (1.22 GB) and a Combo update for those upgrading from previous versions of Lion Server (1.99 GB).

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.
