Apple (AAPL) just released OS X 10.5 Leopard, but a team of programmers has already figured out how to install the new operating system on off-the-shelf Intel PCs. See DailyApps‘ tutorial here for step-by-step instructions.

The procedure is still experimental and has not been thoroughly tested. Some system preferences, like Sound and Network, may never work.

It’s a tour de force nonetheless, one that reminds us of the remark Samuel Johnson made in less enlightened times about women preachers. Like a dog walking on his hind legs, he said, “It is not done well, but you are surprised to find it done at all.”

Warning: Using Leopard this way is a violation of Apple’s license agreement, which states: “This License allows you to install, use and run one (1) copy of the Apple Software on a single Apple-labeled computer at a time.”
