Vector programming doesn't stop with PowerPC. Learn how to do SIMD vector programming for MacOS X for Intel. This page provides an overview of the hardware and programming interfaces involved, and provides detailed translation help information for leveraging your investment in AltiVec forward to the SSE world.

In Tiger, Apple introduced a new system startup program called launchd. The launchd daemon takes over many tasks from cron, xinetd, mach_init, and init, which are UNIX programs that traditionally have handled system initialization and prepared the system for the user. These venerable programs are widely used by system adminstrators, open source developers, managers of web services, even consumers who want to use cron to manage iCal scheduling, and they can still be called with launchd.

An OSX security update includes fixes for the following: AppKit, BlueTooth, CoreFoundation, cups, Directory Services, HIToolBox, Kerberos, loginwindow, Mail, OpenSSL, QuartzComposerScreenSaver, Security Interface, Safari, X11, and zlib.

One of the advantages of OS X's BSD heritage (via Darwin) is that it has access to all the scripting languages found in UNIX(-like) OSes. Here's an introduction to open source scripting.

The big themes seem to be networking and minor annoyances, with a secondary focus on iChat and Mail, which always seem to have problems in the first release of a major Mac OS X version. It’s those changes—along with improvements to Tiger’s disk repair tools—that we’ll focus on during this inside look at Mac OS X 10.4.2.

This could be completely faked, but engadget has a screenshot of OSX x68 running on the x86 virtual machine VMWare. It's an interesting feat if its true, but it also has other implications. Since VMWare obviously does not implement any of the various DRM schemes, this would poke holes in the assertion that Apple is using Trusted Computing in its developer boxes.

Slashdot reports: "Several people have discovered that the new Intel kernel Apple has included with the Developer Kit DVD uses TCPA/TPM DRM. More specifically, it includes "a TCPA/Palladium implementation that uses a Infineon 1.1 chip which will prevent certain parts of the OS from working unless authorized."

Apple Computer this week began asking its developers to test and report back to the company on the first external pre-release build of Mac OS X 10.4.3, a forthcoming maintenance release to the Mac OS X 10.4 Tiger operating system.

According to an announcement posted on the Carbon developer's mailing list, Metrowerks announced at AdHoc that the forthcoming release of CodeWarrior 10 will be the last for OS X. This isn't surprising given that Apple is transitioning to Intel chips and Metrowerks has exited the Intel market, but it's still the end of an era. CodeWarrior literally saved Apple's bacon during the transition to PowerPC in the early 1990s by shipping the first working set of developer tools for the new platform. And since then CodeWarrior has been the main toolkit for commercial development on the Mac (especially pre-XCode).

Do you want to make the most of your Mac applications? Like all operating systems, the Mac has many different levels of programming, and more than 80 percent of all applications built for OS X leverage AppleScript as an automation tool. In this introductory article, Matthew David tells you how you can best leverage AppleScript for your Mac applications.

Apple's MacOS X is making inroads in the business world, according to a report by market research firm Jupiter Research, the report covers desktop and server OS usage in medium to large sized businesses.

Most reviews of Tiger were conducted on fairly new and fast Macs. This article, however, focuses on running it on a low-end Mac. And, to the reviewer's surprise, it runs ok.

Compared to Panther, the Mac OS X 10.3 system software, Tiger exhibits broad performance improvements. It's noticeably faster at booting the system and loading applications. PDF rendering and all text and graphics rendering is faster with Tiger on late-model Macs. Elsewhere, the new IBM chip could serve a PowerBook G5, but is it too little too late?
