Bad news for those hoping for new Macs this year: Intel has announced that its next-generation Broadwell processors, originally promised for the 2014 holiday season, have been delayed until early to mid 2015. Intel is starting production of its low-power Core M Broadwell chips this summer, but the main line of processors won’t see the light of day for several months. Apple may still unveil new Macs this year, including a long-awaited Mac mini refresh, but they will feature last-generation Haswell chips (unless Apple decides to switch the Mac over to the ARM-based processors used in their mobile devices). follow link
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.
