The release of Apple’s long-anticipated Leopard version of OS X has been confirmed for Friday, October 26th, when the company’s retail stores re-open at 6 p.m. and begin selling the new operating system. Where possible, the retail stores will be open until midnight to accommodate the crowds that will appear to purchase the software. Interestingly, the University Village (Seattle), Oakbrook (Illinois) and The Pier (NJ) retail stores were scheduled to be closed October 22 – November 9 for floorplan changes and renovations, completely missing the Leopard event. However, at least the Oakbrook store construction has been pushed back to it’s open for Leopard’s release. Apple has announced that it will give away commemorative T-shirts to the first 500 guests at each store the evening of Leopard’s debut.
