"Leopard started out with a generous share of first-version glitches, but almost all of them have now been resolved by the second of two automated updates, which brings Leopard up to version 10.5.2. Finally, Leopard is extravagantly overdressed for the jobs that it's designed to do, and its pervasive eye-candy starts out looking dazzling but soon becomes distracting. Fortunately, from the beginning, the OS started out with options that let you put it on a low-eye-sugar diet, and the latest update has even more."

"Apple has brought its unique brand of richness and simplicity to servers. OS X Leopard Server is the fifth generation of the software half of Apple's server platform. This time around, Apple took what is a unique and bold approach for a Unix server. Leopard Server continues the OS X Server tradition of delivering platform-independent file/print, e-mail, Web, and network edge services (such as stateful firewall, VPN, proxy, virus, and spam filtering). But it is as easy to set up and run as a desktop. Truly; the typical Mac user could get a Leopard Server going, because the default administrative interface is a match for a Mac's System Preferences."

One of the three authors of Sun's DTrace, Adam Leventhal, has discovered something very interesting using DTrace on Mac OS X. "As has been thoroughly recorded, Apple has included DTrace in Mac OS X. I've been using it as often as I have the opportunity, and it's a joy to be able to use the fruits of our labor on another operating system. But I hit a rather surprising case recently which led me to discover a serious problem with Apple's implementation." So, what is this problem? "Wow. So Apple is explicitly preventing DTrace from examining or recording data for processes which don't permit tracing. This is antithetical to the notion of systemic tracing, antithetical to the goals of DTrace, and antithetical to the spirit of open source. I'm sure this was inserted under pressure from ISVs, but that makes the pill no easier to swallow. To say that Apple has crippled DTrace on Mac OS X would be a bit alarmist, but they've certainly undermined its efficacy and, in doing do, unintentionally damaged some of its most basic functionality. To users of Mac OS X and of DTrace: Apple has done a service by porting DTrace, but let's convince them to go one step further and port it properly."

"When Steve Jobs announced Apples transition to Intel's x86 processor line, a huge stir occurred among some Mac OS X users who depend on 'Classic' the OS9 environment in Mac OS X for their day to day Mac usage, as Mac OS X on Intel means no more 'Classic' and they were right. Rosetta allows PowerPC applications to run on x86 through JIT (Just In Time) architecture emulation, but its translation is not on a low enough level within OS X to allow 'Classic' to work on x86 and as such those among us who use OS9 applications have been left out in the cold. Until now that is: a project called 'Sheep Shaver' was created to allow BeOS on PowerPC emulate the PowerPC architecture to run another PowerPC operating system on top of BeOS. This application was ported to Mac OS X with the demise of Be Inc. and has since been ported to Mac OS X on Intel processors."

"No one is unhappy with Mac OS X Version 10.4, known as Tiger. OS X is not an application platform that needed repair, speeding up, or exterior renovation. Motivations for major upgrades of competing system software - roll-ups of an unmanageable number of fixes, because the calendar says it's time, or because users are perceived to have version fatigue - don't apply to OS X. People buy Macs because the platform as a whole is perfect, full stop. Leopard is a rung above perfection. It's taken as rote that the Mac blows away PC users' expectations. Leopard blows away Mac users' expectations, and that's saying a great deal."

"Ever since I got the eeePC I've loved how easy it is to tinker with. Since I'm not a Linux guy, I dumped the Xandros preload and opted for Windows XP so I could use my EVDO USB datacard and blogging software easier, but I wondered could I install OSX on it? And, after trial and error - you can! The only problem is that the eeePC only supports SSE2 instead of the SSE3 that Leopard is coded for. Kind of a bummer, and will require some extra tinkering to coax the OS on the eeePC."
