In January we discussed a blog entry revealing that Apple had "crippled" its DTrace port. As the author notes in a followup post, to say that DTrace had been "crippled" was at least overstated: "Unfortunately, most reactions seized on a headline paraphrasing a line of the post — albeit with the critical negation omitted." In an updated entry, the poster notes that Apple has made good (so we have too): "One issue was that timer based probes wouldn't fire if certain applications were actively executing (e.g. iTunes). This was evident both by counting periodic probe firings, and by the absence of certain applications when profiling. The good news is that Apple has (quietly) fixed the problem in Mac OS X 10.5.3."

4roddas writes "Reports circulated Wednesday that Apple may demo the next iteration of Mac OS X next week or even release code to developers in preparation for an early-2009 launch. According to an account on Mac enthusiast site TUAW (The Unofficial Apple Weblog), Apple may provide early copies of Mac OS X 10.6 at next week's Worldwide Developers Conference (WWDC), which opens Monday and runs through next Friday in San Francisco. Mac OS X 10.6 will run on Intel-based hardware only, said TUAW, and so will mark the ditching of support for the older PowerPC processor-equipped Macs. Apple announced it would shift to Intel processors three years ago, and unveiled the first systems in January 2006; most analysts have said that move is largely behind the reason for Apple's renewed success selling personal computers. It has never disclosed how long it would support the PowerPC with OS upgrades, however. Ars Technica also weighed in Wednesday on Mac OS X 10.6; its sources pegged with OS with the code name 'Snow Leopard.'"

Wormfan writes to share ZDNet's brief mention of and a link to "Apple's release of a ~250 page PDF of security best-practices and tips to protect Mac OS X Leopard clients. The guide is aimed at experienced users, Apple says, familiar with the Terminal application and its command-line interface."

jaymus of dawning writes with word that, as promised, "Apple has just released the latest major revision of OS X. The update yields improvements to tons of system components and applications including the Software Update system, Address Book, AirPort, Automater, iCal, iChat, Mail, Parental Controls, Spaces, Time Machine and VoiceOver. This release contains 200 bug fixes from 10.5.2. See Apple's release page for all the delicious details."

An anonymous reader writes "MacScoop reports that 'Apple has seeded several builds of its Mac OS X Leopard 10.5.3 update to developers during the past few weeks and just seeded yet another one numbered "9D34" earlier today.' The update fixes over two hundred bugs, weighs almost half a gigabyte and should be available soon."

wchatam writes "After a long delay, Apple has finally released a version of Java 6 for OS X. 64-bit Intel Macs are starting to see this pushed out via Software Update, but there has not been an announcement for when 32-bit Intel and PowerPC Mac users will get their versions."

An anonymous reader writes "According to Gizmodo, Psystar has begun shipping its Macintosh clones, thus proving that the company is not a hoax. Initial impressions seem to be positive, though Software Update does not work."

HighWizard notes that Adobe Systems has shared the first scrap of information about its next version of Photoshop, CS4, and it's a doozy: there will be a 64-bit version of the photo-editing software, but only for Windows Vista and not for Mac OS X. Ars explains the history of how this conundrum came to pass — blame Apple and/or Adobe as you will.

billybob2 writes "PolishLinux.org has an extensive screenshot review and commentary on the development version of the Free and Open Source KDE desktop. Highlights include the ability to run any desktop applet prepared for Mac OS X inside Plasma, on-the-fly annotation and rating of files from within the Dolphin file manager. It also has an improved GUI for the Amarok music player, flexible 3D eye candy configuration in KWin, and improved support for both accessing digital cameras via the Solid hardware layer and the DigiKam photo manager."

jsuda writes "The preeminent general reference source for Mac OS X has always been the Missing Manual Series written by David Pogue. The latest iteration in the series is its Mac OS X Leopard Edition, completely revised, and it is the biggest, most comprehensive, and most useful of all the editions in the series. It covers the Mac OS X desktop and file system, the free applications included with the Mac OS X installation, the system components and technologies, networking and online features and components, and includes welcome appendices on installation, troubleshooting, Windows/Mac comparisons, and a Master Keystroke list." Read on for the rest of John's review.

theodp writes "A recent Amazon SEC filing sheds light on the puzzling departure of Microsoft Sr. VP Brian Valentine in Sept. 2006. Valentine is the Gen. George Patton-like figure charged with pushing Vista developers, who dumped the still not-ready-for-prime-time OS into RC1 status as he bolted for a new gig at Amazon. Having repeatedly assured everyone that Valentine was staying with the company post-Vista, Microsoft backpedaled and explained that Valentine decided to leave since the company had shipped a near-final version of Vista. Not so. Although analysts fell for the PR line, it seems Valentine had actually signed an Employment Agreement way back in June calling for him to be on board at Amazon on Sept. 11 if he wanted to pick up a $1.7M signing bonus, $150K base salary, another $500K bonus, and 400K shares of Amazon stock (now worth almost $30M). Who says you have to shell out $999.95 for MS-Project to come up with accurate planned completion dates?"

jlgolson writes "Yesterday, Rush Limbaugh complained on his radio program about some problems that he was having with his Mac: 'Mr. Jobs, please help me. I know we don't agree on anything ... But can you put me to somebody that can get this going, because I know it's gotta work for most people. What am I doing wrong?' Eventually he shared that he was running into actual problems with Time Machine and Back to My Mac. Can you fix them?"

jetpack writes to make sure we're aware that Apple's OS X 10.5.2 update is available and that it contains plenty of improvements and fixes that users have been asking for. Macworld enumerates some of the big ones, saying that the update "shows Apple listens to users" (sometimes). A couple of the new features simply restore Tiger (10.4) capabilities that Leopard (10.5) had inexplicably withdrawn. You can now shut off the much-maligned transparency of the menu bar, and organize your Dock stacks hierarchically and display them as folders. And Apple has provided welcome access to common Time Machine functions in the menu bar.

klblastone writes "The KDE desktop environment is going cross-platform with support for the Windows and Mac OS X operating systems. In addition to porting the core KDE libraries and applications, developers are also porting popular KDE-based software like the Amarok audio player and the KOffice productivity suite. New KDE binaries for Windows were released yesterday and are now available from KDE mirrors through an automated installer program. The Mac OS X port is made available via BitTorrent in universal binary format."

Linnen writes in to note that one of developers of Sun's open source system tracing tool, DTrace, has discovered that Apple crippled its port of the tool so that software like iTunes could not be traced. From Adam Leventhal's blog: "I let it run for a while, made iTunes do some work, and the result when I stopped the script? Nothing. The expensive DTrace invocation clearly caused iTunes to do a lot more work, but DTrace was giving me no output. Which started me thinking... did they? Surely not. They wouldn't disable DTrace for certain applications. But that's exactly what Apple's done with their DTrace implementation. The notion of true systemic tracing was a bit too egalitarian for their classist sensibilities..."

nezmar writes "Noel Dellofano, who is part of the ZFS development team at Apple, has a post on Mac OS Forge announcing a late Christmas gift: he is making available binaries and source code, plus instructions, of the ZFS filesystem for Mac OS X."

walterbyrd writes "Linux magazine has up a decent article comparing Gutsy Gibbon to Leopard. 'The stereotype for each OS is well known: Mac OS X is elegant, easy-to-use, and intuitive, while Ubuntu is stable, secure, and getting better all the time. Both have come a long way in a short time, and both make excellent desktops. So we have two great desktop operating systems out at roughly the same time. Let's see how they stack up against each other.'"

ozmanjusri writes "Coders working on Wine for Mac have found that the Mac loader has gained its own undocumented ability to load and understand Windows Portable Executable (PE) files. They found PE loading capabilities in Leopard that weren't there in Tiger. Further dissection showed that Apple is masking references to 'Win' and 'PE' in the dll, which means it's not an accidental inclusion. Is Apple planning native PE execution within OS X?"

ninja_assault_kitten writes "There's an interesting rant from Oliver Rist up on the PC Magazine site. He compares the catastrophe that is Vista to the recently released OS X Leopard. While clearly one is a lion and the other a cub, there do appear to be some frustrating similarities. From the article: 'A month of using Leopard with the same software I had under Tiger and the OS has dumped six times. That's six cold reboots for Oliver. Apple isn't even honest enough to admit that Leopard is crashing: The OS just grays out my desktop and pops up a dialog box telling me I've got to reboot. Like the whole thing is my fault. I even snapped a picture of it. After all, I HAD PLENTY OF CHANCES!'"

LarsWestergren writes "Many Mac users have been upset that Apple has not made Java 6 available on the platform. Landon Fuller posts that there is a developer preview release available of Java JDK6 on Mac OSX, Tiger and Leopard. It is based on the BSD port of Sun's Java 6 and is made available under the Java Research License. Charles Nutter posts about impressive JRuby performance gains using Java 6 on his Mac."
