The Apple Developer Center has been offline since Thursday, 18 July 2013, and after days of silence and much speculation, Apple finally sent email to developers on Sunday, explaining that it had detected an intruder and shut down the developer Web site. Apple says that it is completely overhauling its developer systems, updating server software, and rebuilding the entire database, so it is uncertain when the system will be available again. In the meantime, developers can’t obtain identities, certificates, or provisioning profiles, making it impossible to distribute an app for testing or submit it to the App Store. Apple developer forums are also offline. 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.
