Apple Updates Mac OS X 10.5 (Leopard) to 9A528d

After nearly a month without an update, Apple has delivered a Leopard update to developers. First, a new version of the Leopard Software Update Client has been seeded through Leopard's Mac OS X Software Update. Once this new Software Update tool is installed, Apple also provides Mac OS X Leopard Client Seed Update.

The new Seed Update is "recommended for all users running Mac OS X Leopard 9A527 or 9A528" and brings the Leopard build up to 9A528d. The update includes general fixes and is also meant to test the new version of Software Update.

Leopard seeds have been notably absent in the past 3-4 weeks. Apple's October deadline for Leopard is quickly approaching. Leopard will need to be finalized soon to ramp up duplication and distribution for the October release timeline.

Apple's last major Mac OS X release (Tiger, 10.4) was declared Gold Master on March 31, 2005. Tiger was later launched in retail stores on Friday, April 29th, 2005, almost one month later.
