Apple’s Mac OS X 10.5.6 Update due soon with 100+ fixes; Snow Leopard dev docs reveal focus areas

“Apple’s Mac OS X 10.5.6 Update is on course to deliver dozens of new bug fixes to users of the company’s Leopard operating system, with recently leaked developer notes also offering a status update on software’s server counterpart and Mac OS X 10.6 Snow Leopard,” Slash Lane reports for AppleInsider.

“Recent weeks have seen the release of two new builds of Mac OS X 10.5.6 to Apple developers, namely builds 9G44 and 9G52. Leaked evaluation notes from the latter build lists 103 specific bug fixes that will be deployed with the official release of the software, now expected shortly before the holidays,” Lane reports.

“Partial developer documentation reveals the most recent pre-release build of Mac OS X 10.6 Snow Leopard to be 10A222. Corroborating an AppleInsider report from last week, the notes show the software to have recently gained a new Grand Central developer API, while testing of Microsoft Exchange functionality in Mail, Address Book and iCal remains a focal point,” Lane reports.

“Additionally, the notes show hardware support for Snow Leopard’s 64-bit kernel to remain limited to Macs introduced during the first half of the year, namely the early 2008 Mac Pro, early 2008 iMacs, and early 2008 MacBook Pro,” Lane reports. “Apple will extend 64-bit kernel support to additional Macs as Snow Leopard development progresses.”

  1. Looks like I’m golden. I got my iMac just this past June. I’d say “Bring on that Bad Cat (Snow Leopard)”, but I’ve barely cracked Pogue’s “Missing Manual” to Leopard. So much yet to learn, so little time.

  2. I still think Apple’s lack of G5 support is terrible. Apple sold the G5 until August 2006 (later if you count clearance sales, refurbs, etc.). So, they are supporting this class of computer for less than 3 years?

    I can understand not support G4’s due to their age and performance-crushing, dirt-slow, front side bus speeds, but the G5’s?!?!?

    I just hope Apple releases later versions of Leopard with some of the code rewrites going into Snow Leopard. It would be sweet if 10.5.10 is like a startover and Apple cranks out upgrades for another year or so after Snow Leopard is released. I can only hope.

  3. “Doesn’t work on my 256k Mac either.”

    That’s funny. Turbo Pascal for the Mac listed “at least 256K RAM” in it’s specs. There (and now here) are the only two places I’ve ever seen reference to a 256K Mac.

    The original Mac had 128K RAM of course. And the next model, The Fat Mac, had 512K.

  4. “Is the G5 a 64-bit processor? If it isn’t then Snow Leopard will run just fine on it.”

    1 – YES the G5 is a 64-bit processor. And like Intel’s new 64-bit processors, it will run both 32- and 64-bit software.

    2 – NO. Unless something changes before release, Snow Leopard requires an Intel processor.

  5. The lack of support for PPC systems has little to do with their age or their ability to deal with 64-bit vs 32-bit. It is the way the chip is built – significantly different from the Intel family. In essence, we have been getting two OSs for the price of one – one for the PPC and the other for the Intel. Not that there is any way you can unlink the two, but there is code for both platforms there. Not for Snow Leopard, though. This will be a nearly clean sweep of all the older code. Not as complete as what went for Classic, but better than MS did for Vista.
