NY Times review of Panther Panther Rocks! Panther is Coming As of this posting Panther will be available in 9 days 21 hours and 35 mins. You can officially buy OS 10.3 at 8PM on October 24th. UCBMUG will be having 2 events in the next few weeks to celebrate panther's release. On the 24th we expect to join fellow macsters with uncontained joy at the Emeryville Apple store to countdown. Also a week later we plan to have a casual pizza party so you can meet the new rep, and hopefully get mac freebies. Learn more in the events section.
