OS X Leopard, Tiger Treated for Feline Distemper

Apple’s latest security updates include so many fixes that you might mistake them for a Windows Service Pack.

Among the 25 issues repaired in Leopard 10.5.1: a major one that resulted in a “potential data loss issue when moving files across partitions in the Finder” as well as other problems with Time Machine, Firewall, Back to My Mac, Airport and Mail.

The release of OS X 10.5.1 follows hot on the heels of OS X 10.4.11, Apple’s 11th and likely final update to Leopard’s predecessor, Tiger, which patched 41 vulnerabilities in the OS.
