![]() Apple released Four New Colors for the 2G iPod shuffleĪpple's second generation (2G) iPod shuffle was originally released in just one color, silver. We look forward to receiving a new AirPort Extreme 802.11n Base Station and testing the faster speed that 802.11n WiFi protocol provides. In several hours of use, we encountered no problems with our AirPort wireless network. Our 15" MacBook Pro CSD is about a yard from the Base Station and the 24" iMac C2D is about 10 yards away. On both of our Macs, AirPort's menu bar icon displays four arcs and Internet Connect displays 15 dots so we get the same strong signal from our 802.11g Base Stations. It should read "Model Wireless Network Adapter (802.11 a/b/g/n)." Ours was missing the "/n" before installing the enabler. To determine if 802.11n is enabled, open Network Utility and under the Info tab select the Network Interface (en1) from the popup menu and look at the last entry of the left panel. This License allows you to install and use one copy of the Apple Software on all computers under your ownership or control, so only needs one legitimate copy of the enabler making the $1.99 charge truly trivial. In fact, Apple is adding a significant new feature to Mac OS X, not just enabling the hardware already installed and disabled, a significant difference to accounting rules. It is not a firmware upgrade but new code that is added to Mac OS X 10.4.x "Tiger" which explains the $1.99 charge. The 802.11n enabler downloaded and installed fine on both Macs. After buying it for $2.14 including CA sales tax, its receipt has a download link to click to obtain the enabler. We believe this is the first time that Apple has sold software as a download from the Apple Store. ![]() The purchase process at the Apple Store was straightforward, just like buying software from any other online vendor. We have a new AirPort Extreme 802.11n Base Station on order which includes the $1.99 enabler but it is not scheduled to ship until February 28th. We bought a copy of the enabler to see how the Apple Store's purchase process works and to confirm that the enabler does not cause issues with our 15" MacBook Pro C2D or our 24" iMac C2D and our AirPort Express and AirPort Extreme 802.11g Base Stations. It costs $1.99 plus tax as a download via the Apple Store at this Apple Web page found under "Mac Accessories, AirPort & Wireless." The enabler allows Core 2 Duo Macs to run the new super fast draft WiFi protocol dubbed 802.11n. ![]() LCC «Russian Superconductor».Brief Hands-On Report-AirPort Extreme 802.11n Enabler for MacĪpple released the AirPort Extreme 802.11n Enabler for most Macs with Intel Core 2 Duo processors.
