Ergonis Software has released PopChar X 6.6 with support for Unicode 7.0, which integrates 2,834 new characters (including symbols such as the Russian ruble and nearly 250 emoji symbols). The font discovery utility also improves the Scripts and Symbols layout to better match definitions in the Unicode standard, and adds a Show in Unicode Context features that enables you to discover similar characters within the Unicode table. The update also quickens the speed of displaying the character table and various unspecified housekeeping tasks, improves visibility of the PopChar icon against the dark menu background of OS X Yosemite, fixes several cosmetic issues related to Yosemite, and squashes a bug that resulted in a misplaced magnifier after scrolling operations.

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.
