Release notes

What changed

Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.

Public release

Apple put Panther on sale at 8:00 p.m. on Friday, October 24, 2003 through its online store, retail stores, and authorized resellers. The local catalog has one matching public milestone and no separate launch build.[1][2]

What this page records

The structured entries synthesize twenty-eight confirmed parts of the initial client package: twenty-one public-package entries, including FileVault as an introduced security feature, plus seven grouped vulnerability-correction deltas. Each entry points to retained first-party Apple material.[3][4][5][6]

Launch highlights

The release centered on Finder and Exposé for navigation and window management, iChat AV and Fast User Switching for communication and shared Macs, FileVault for home-directory protection, revised Mail and Preview workflows, broader Windows and UNIX interoperability, and Xcode for development.[7][8]

Initial security record

Apple's security archive assigns initial Panther corrections to Finder, the kernel, slpd, ktrace, NFS, zlib, gm4, OpenSSH, nidump, System Preferences, TCP timestamps, Mail, and the Dock. Default-state and theoretical-exposure qualifications are preserved in the grouped change summaries instead of presenting every issue as equally reachable.[5]

Later-update boundary

QuickTime Java on October 28 and Terminal on November 4 were later security updates. The same archive labels a November 19 package for Panther 10.3.1. Because no 10.3.1 version exists in the scoped local catalog and the archive does not establish its exact general-release date, this batch neither creates that point release nor merges its OpenSSL and zlib changes into launch day.[9]

Distribution context

Panther used simultaneous retail availability rather than the phased device rollout associated with some modern software tracks. The page records the dated public appearance and product baseline, but it does not turn store events into artificial rollout stages.[10][11]

Release changes

Changed in this release

Features, fixes, removals, and regressions first observed in this release record.

security · fixed

zlib and gm4 preventive hardening

documentedconfirmed

Apple states that no Mac OS X function used the vulnerable zlib gzprintf function and that no setuid-root program relied on gm4, so CAN-2003-0107 and CAN-2001-1411 are recorded as preventive hardening rather than evidence of an exploited default path.

OpenSSH and nidump credential protections

documentedconfirmed

Finder mounted-volume permission preservation

documentedconfirmed

Apple associates CAN-2003-0876 with copies from mounted sources such as disk images and lists the correction directly under the initial Mac OS X 10.3 Panther release.

Personal File Sharing and NFS hardening

documentedconfirmed

The slpd correction addressed CAN-2003-0878 when Personal File Sharing was enabled, which Apple says was off by default. The NFS correction addressed CVE-2002-0830 involving crafted RPC messages.

Faster Finder search

documentedconfirmed

Apple advertised Finder searches as up to six times faster than Jaguar. That comparison is preserved as an attributed vendor performance claim, not an independently reproduced benchmark.
