Apple made an in-house parody ad of its famous “1984” ad called “1944” that has to be seen to be believed. A long-ago Apple employee, Craig Elliott, provided the video to Network World’s Paul McNamara. Steve Jobs does an impression of FDR, among other bizarre moments. It was made to pump up Apple’s sales force, and may not have been seen since 1984.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.
