New from Apple is Digital Camera RAW Compatibility Update 3.9, which adds compatibility with several new cameras to Aperture 3 and iPhoto ’11. The newly supported cameras include the Canon PowerShot S100; Nikon 1 J1, 1 V1, and Coolpix P7100; Olympus PEN E-PL1, PEN E-PL3, and PEN E-PM1; Panasonic Lumix DMC-FZ150; and Sony Alpha NEX-5N, Alpha SLT-A65, and Alpha SLT-A77. The update applies to both Mac OS X 10.7 Lion and 10.6 Snow Leopard; Apple publishes a full list of supported raw image formats in both Lion and Snow Leopard — interestingly, the Lion list is a bit longer.

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.
