Introduction and announcement; not a sales date.
Apple source ↗Apple announced Leopard Server, Mac OS X Server 10.5, on October 16, 2007, with availability planned for the 26th. Pre-orders opened on announcement day. In the US, ten-client and unlimited editions cost $499 and $999; Xserve included an unlimited licence. It was not a free server for everyone who owned the Leopard client.

Server Assistant configured services, networking and accounts; Server Preferences simplified routine management. Leopard clients could automatically receive Mail, iChat, iCal, contacts, file-sharing and VPN settings from server-held information. A Server Status widget monitored activity and usage remotely. The goal was less manual configuration, not the removal of administrator responsibility.

Wiki Server added collaborative pages with revision history, comparison, restoration and tags. Podcast Producer automated uploading, conversion and publishing of recorded content. iCal Server used CalDAV for shared calendars and meeting coordination. These were distinct server services, not modern iCloud applications projected into the past.

Apple described 64-bit core services including Apache 2, MySQL 5, Postfix, Podcast Producer and QuickTime Streaming Server, with 32-bit applications running alongside them. The announcement required Intel, PowerPC G5 or a G4 at 867 MHz or faster, 1 GB RAM and 20 GB free. The $9.95 upgrade program covered only qualifying new Xserve purchases from October 1, 2007.

In a Macworld preview, John C. Welch distinguished Standard and Workgroup modes from Advanced setup and explained collaboration and messaging integration. This was a pre-sale preview, not a production audit. The page states that an erroneous DFS paragraph was removed on October 23: that withdrawn claim is not restored here, nor is his enthusiasm treated as an independent performance test.
