The release of an Apple OS is always an event, but the debut of the Tiger upgrade to the Mac X Friday night brought out the wild side of hundreds of users who lined up at Apple retail stores throughout the country, some capturing the spirit in animal oufits.At the official opening time of 6 p.m. in San Francisco, the line outside an Apple Store snaked up Stockton Street wrapping around to O’Farrell, wrote Mac-world’s Channing Joseph, with a contribution from Philip Michaels.Ten minutes before the store opened its doors, more than 200 people were lined up, waiting to get their hands on Tiger and its promised 200 features and enhancements, Joesph wrote. First-in-line honors went to Mario Ortiz, who showed up at the Apple Store two hours before the Tiger event. Ortiz, from San Francisco, had ordered a copy of OS X 10.4 from Amazon.com, but the software hadn’t arrived yet; he decided to come down to the San Francisco store to get his hands on a copy. “I’ve pretty much been an Apple fan for a while,” said Ortiz, adding that he makes it a habit to be among the first adapters of Mac operating systems. “I want to keep up the tradition.”Right behind Ortiz was San Franciscan David Dellinger, who came to the Apple Store even though he planned to wait a week or two before installing Tiger to “let the dust settle,” according to Macworld.“I had never come to a launch event before,” said Dellinger, who was eager to try out the latest version of iChat AV. “Hands down, the quality (of iChat’s video )is so much better than what’s out there.” In New York, hundreds of Mac users in the SoHo neighborhood of Manhattan stood patiently in line and watched a man in a cat suit dance to the tune of “Eye of the Tiger,” promoting the debut of Apple’s new operating system.Costumes weren’t just restricted to customers, Macworld reported. At the San Francisco Apple Store, employee Nikki Bongard donned a set of ears and pair of Tiger-stripped sleeves to help greet patrons. “You’ve got to get into the spirit,” she said.
