“Leopard maintains all the goodies of previous Mac OS X versions. To the amazement of many Windows refugees, Mac OS X requires no serial number and no ‘activation’; it’s not copy-protected. It doesn’t clutter the desktop with crippled bits of free-trial software from other companies. There are no nagging balloons or come-ons,” David Pogue reports for The New York Times.

“Leopard does well with backward compatibility, too. Thanks to modest minimum requirements (512 megabytes of memory, 867 megahertz), Apple says Leopard runs on three-year-old Macs and even high-end six-year-old machines,” Pogue reports.

“Leopard is powerful, polished and carefully conceived. Happy surprises, and very few disappointments, lie around every corner. This Leopard has more than 300 new spots — and most of them are bright ones,” Pogue reports.
