If you find yourself regularly needing to find and enter special characters in different fonts, that task has now become easier in Mac OS X 10.7 Lion, with Ergonis Software’s release of PopChar X 5.3. The new release supports colored symbols in the new Apple Color Emoji font; these can now be browsed and searched for, and inserted as characters in applications that know how to handle color fonts. Some additional tweaks, such as reduced CPU load in the background and better compatibility with Lion’s desktop spaces, round out the update. (€29.99 new, free update, 2.3 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.
