Release notes

What changed

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

Public appearance and retail availability

Apple announced the finished 10.1 client upgrade on September 25 at Seybold and dated its companion application announcement the same day. The release announcement says stores would begin broad distribution on September 29; TidBITS reported that Seybold attendees could obtain the free upgrade at Apple's booth during the conference. The existing September 25 Public route is retained with this availability split disclosed.[1][2][3]

What this page records

The 29 structured changes cover performance, Aqua, digital media, cameras, bundled applications, network protocols, printing, graphics, color, audio, scripting, distribution, hardware, and the security corrections Apple places under the initial 10.1 heading.[4][5]

From preview to release

Apple's July preview supplied early interaction detail, but no separate prerelease event is created because the seed contains only Public. Every preview-derived feature used here is independently named by the September shipping announcement.[6][7]

Upgrade distribution

The 10.1 upgrade was too large for Apple's ordinary Software Update delivery at the time and was distributed on CD. Existing owners had paid mail-order and temporary free pickup options; new customers could buy the full retail package.[8][9]

Security boundary

The security inventory is limited to entries Apple lists under Mac OS X 10.1 itself. The October 19 privilege update, Internet Explorer 5.1.1, and 10.1.3 through 10.1.5 belong to later packages and are not inherited.[10]

Client and server boundary

This page covers the desktop client. Apple's separately announced Mac OS X Server 10.1 included server-specific storage, NetBoot, directory, database, web, and streaming changes that do not belong on this route.[11][12]

Naming boundary

The local record carries the retrospective version note “Puma,” but the retained public Apple material calls the product Mac OS X version 10.1. Reader-facing copy uses that period name and does not present the catalog note as launch branding.[13]

Evidence boundary

Apple's benchmark multipliers, application count, and partner statements are vendor-supplied. They are kept as attributed launch context and are not converted into independent performance, compatibility, or adoption conclusions.[14][15]

Release changes

Changed in this release

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

developerApi · introduced

Revised high-resolution audio architecture

documentedconfirmed

Apple documented these capabilities as an operating-system audio foundation rather than a guarantee that every application or device used the maximum format.

  1. [1] First Major Upgrade to Mac OS X Hits Stores This Weekend · Additional features; audio architecture

security · fixed

fetchmail input and memory safety

documentedconfirmed

Apple grouped three upstream fetchmail issues under the initial 10.1 security content; this occurrence keeps them together at their shared component boundary.

  1. [1] Apple security updates (August, 2003 and earlier) · Mac OS X 10.1; fetchmail

behavior · introduced

Automatic file-extension management

documentedconfirmed

Apple described the feature as automated file-extension management across common file workflows without publishing a format-by-format behavior table.

  1. [1] First Major Upgrade to Mac OS X Hits Stores This Weekend · System status and file-extension paragraph

enhancement · changed

iTunes and iMovie included in installation

documentedconfirmed

The packaging change made Apple's music-management and movie-editing applications part of the standard installation path.

  1. [1] First Major Upgrade to Mac OS X Hits Stores This Weekend · Image Capture and bundled applications paragraph

security · fixed

OpenSSL 0.9.6b security maintenance

partiallyDocumentedconfirmed

Apple's retained chronology confirms the updated version but does not enumerate the individual OpenSSL issues on the page, so this occurrence stays at package level.

  1. [1] Apple security updates (August, 2003 and earlier) · Mac OS X 10.1; OpenSSL

security · fixed

setlocale, sort, and tcsh utility safety

documentedconfirmed

Apple's chronology describes potential exploitation through setlocale string overflows, disruption of administration tools through sort, and an unprivileged-user overwrite condition in tcsh. The shell operator is not repeated because the retained entry's title and explanation use inconsistent notation.

  1. [1] Apple security updates (August, 2003 and earlier) · Mac OS X 10.1; setlocale() string overflow
  2. [2] Apple security updates (August, 2003 and earlier) · Mac OS X 10.1; sort
  3. [3] Apple security updates (August, 2003 and earlier) · Mac OS X 10.1; tcsh operator

security · fixed

tcpdump packet-input safety

documentedconfirmed

Apple described a remote packet source affecting the local capture process and preserved possible code execution as a qualified outcome.

  1. [1] Apple security updates (August, 2003 and earlier) · Mac OS X 10.1; tcpdump

compatibility · changed

Expanded printer setup and drivers

documentedconfirmed

The package added drivers from HP, Canon, and Epson plus PPD files for more than 200 PostScript printers from HP, Lexmark, and Xerox.

  1. [1] First Major Upgrade to Mac OS X Hits Stores This Weekend · Additional features; printing

security · fixed

telnetd remote code execution

documentedconfirmed

The occurrence preserves the service-account privilege boundary stated by Apple and does not imply the service was enabled by default.
