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.

MacBook Pro Retina EFI Updates 1.2 and 1.3

Send Article to a Friend

Apple has released two EFI firmware updates that provide targeted fixes for specific models of the recently released lineup of the MacBook Pro with Retina display (see “New Retina MacBook Pro Models Thinner, Lighter, and Cheaper,” 22 October 2013). EFI Update 1.2 is aimed at the high-end version of the 15-inch MacBook Pro model with Nvidia GeForce GT 750M graphics, addressing a rare problem that limits the performance of the Nvidia graphics processor after a system wake or boot. EFI Update 1.3 is directed at 13-inch models to fix an issue where the built-in keyboard and trackpad could become unresponsive. As always with firmware updates, we recommend relying on Software Update to ensure you get the firmware update for your specific model, and be careful not to interrupt the update process.

Comments about MacBook Pro Retina EFI Updates 1.2 and 1.3

MacBook Pro Retina EFI Updates 1.2 is being offered for 15" versions without the Nvidia card. There are several comments on other forums. I'm not installing it on my Intel Iris Pro model.

After 20 year on win doze, I bought a MBP yesterday and am once again on a MAC. A marvel! Windows 8 and touch screens on laptops drove the decision. Glad to see Tidbits is still around. I found it while searching for this subject.

Cheers, Don
