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
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
