Anyone else with the GM of Snow Leopard?
Have you tried the arch=x86_64 modification to the com.apple.boot.plist ?
When I use arch=x86_64, I get 100% true 64 bits on my Macbook Pro and my iMac, but my 2009 Mac Mini is stuck in 32 bits.
Leopard 10.5.8 runs fine on this 2.26ghz Mac Mini. BUT every time I try to install Snow Leopard, with about ten minutes left in the installation process, I get a kernel panic. The only thing I can think of that is doing this is either 1. I am driving a 30" Cinema Display through a mini dvi to dvi adapter on the Mini -- reducing resolution but still running it fine (I do this with my 12" Powerbook 1.5ghz as well, doing it now as a matter of fact. It makes the picture huge but fine for me at moment) 2. 3rd Party Ram bought at Fry's Patriot 2 x 2GBs ... but passed hardware tests and no problems in 10.5.8. 3. I have not done all the imovie/garageband/idvd/remote desktop/itunes 9 updates in Leopard. I have done all the other updates to 10.5.8 and don't use these apps, so can't see how this is affecting a Snow Leopard update. Any thoughts? It quits and kernel panics during the Snow Leopard update. It was kernel panicking in Leopard, too, when using iPhoto a few weeks ago. Wondering if it is something to do with the Mini Dvi to Dvi adapter (not dual link) to 30" Cinema Display?

I don't know much about the Snow Leopard Server OS and I was wondering if I should stick with regular Snow Leopard. I'm only using the Mac Mini for HTPC and streaming media to my iPhone and iPad.

Now when I upgraded I get more options for monitoring HD signals but my TV signal drops out intermittently. I suspect this is a bug with Snow Leopard and HDMI. Anyone have any inklings on how to solve this issue?
View 1 Replies View RelatedAs jingle-pundits desperately try to denigrate Snow Leopard as a "Service Pack," Apple's new operating system reference release actually expands the reach of the Mac platform in several important and under-reported new directions. Here's the second in a series looking closer at some of Snow Leopard's well-known, but often misrepresented or misunderstood features.
The 64-bit Kernel
It seems fashionable to describe Snow Leopard's new 64-bit kernel as a problem for Mac users with 32-bit EFI (the startup firmware that launches the operating system). It's true, 64-bit Core2 Duo machines prior to 2008 still run Snow Leopard's 64-bit apps using a 32-bit kernel, because Apple's 64-bit kernel requires both a 64-bit processor (a Core2 Duo or better) and 64-bit EFI.
The 64-bit edition of Windows XP or Vista will run on 64-bit Macs with 32-bit EFI via Boot Camp because Windows doesn't use EFI; it still lives in the simpler world of BIOS.
However, running a 64-bit kernel on these machines is of limited benefit. While there are certain advantages with the move to a 64-bit kernel, including new security enhancements, the primary benefit of a 64-bit kernel is being able to directly work with significantly more than 4GB of RAM, something that most existing consumer Macs and generic PCs can't do anyway.
For this reason, Snow Leopard also defaults to running its 32-bit kernel even on consumer models with 64-bit EFI. This prevents mainstream users from running into problems related to incompatible kernel extensions and device drivers (such as printer software), which aren't yet 64-bit.
This problem has helped repress the popularity of the 64-bit editions of Windows over the last several years, but won't hold up 64-bit Mac adoption because there is only one edition of Snow Leopard, one that runs on all Intel Macs and simply adjusts itself to the limitations of the given hardware.
Users who want to run the new 64-bit kernel on late modeled Macs (pretty much anything released after early 2008) can do so by booting with the 6 and 4 keys held down. If you're wondering whether your Mac has a 64-bit EFI firmware, you can type the command "ioreg -l -p IODeviceTree | grep firmware-abi" into the Terminal. The response will identify the machine as either having 32-bit or 64-bit EFI.
64-bit System Apps
What Snow Leopard does do is bring all Core2 Duo, 64-bit Macs (pretty much everything sold since 2007) up to speed with 64-bit system apps, from the Finder and Dock to iChat and Mail to background processes such as launchd and the system-wide spell checker. Running the 64-bit kernel or not, the singular version of Snow Leopard always runs 64-bit apps when running on 64-bit hardware; in contrast, no 32-bit editions of Windows can run 64-bit apps, even on 64-bit capable hardware.
Snow Leopard's upgrade to 64-bit system apps provides an overall speed boost due to limitations in the original design of Intel's 32-bit chips; the move to the new 64-bit x64 processor model, originally developed by AMD, solves these issues. Moving to 64-bit apps on other processor families, such as PowerPC, does not yield the same boost, but rather only incurs additional overhead, one of the reasons Snow Leopard is Intel-only.
Windows XP/Vista/7 users also benefit from running 64-bit apps, but Windows can only run 64-bit apps using the 64-bit kernel provided with the 64-bit "edition." This prevents mainstream generic PC users from realizing the benefits of the move to 64-bits unless they are equipped to make the full jump, which requires lining up 64-bit kernel drivers for all their hardware. This sticky bit has kept 64-bit adoption on Windows very low despite the significant advantages related to making the move.
Snow Leopard does not share this problem, because it has no problem running 64-bit apps using its 32-bit kernel. Additionally, Apple's unique Universal Binary specification packs both 32-bit and 64-bit code into each application, making Snow Leopard's 64-bit capable apps backwardly compatible with 32-bit Macs.
64-bit Third Party Apps
Snow Leopard also lays a strong foundation for 64-bit third party apps. While Leopard could run 64-bit graphical apps and even Tiger could run 64-bit background processes, the delivery of 64-bit Mac apps is just getting started. Even Apple is behind the curve on that front, with iWork, iLife, iTunes, and even its Pro Apps all still in 32-bit land. Microsoft Office and Adobe Creative Suite are also waiting for a 64-bit overhaul.
Snow Leopard's 64-bit kernel enables new generations of Macs that can use far more memory, unlocking new potential and more efficient performance by easing existing bottlenecks and allowing more aggressive caching, particularly for kernel i/o such as disk access. Third party Mac software titles that can benefit from the jump to 64-bits will likely begin to transition to full 64-bit capable binaries at a faster pace than the Windows side overall, because the majority of the installed base of Windows PCs are still running the 32-bit edition of XP, which unlike Snow Leopard, can't run 64-bit apps at all.
Snow Leopard delivers a performance boost to existing users of 64-bit Macs, but it really lays a foundation for 64-bit, high performance computing in the next few years. Thanks to the long standing 32-bit barrier that has held up the PC demand for large amounts of memory, RAM is now cheaper than ever, making the ability to install large amounts of memory that the operating system can actually use something that mainstream Mac users will hold as an advantage over the mainstream of 32-bit PC users.
That's because mainstream generic PCs are limited not just to 4GB of RAM, but also incur additional artificial limitations under Windows, where the operating system takes 2GB leaving only 2GB available for the running application. Mac OS X, like Linux, has always allowed applications the full 4GB available on the Intel architecture. This difference has given Windows a translation lookaside buffer performance advantage in the past, but Snow Leopard's new 64-bit applications erase this lead and instead provide Macs with the upper hand relative to the billion installed base of Windows PCs.
Additionally, as all modern Macs transition to 64-bit apps in a single leap, the Windows installed base will effectively splinter between the mass market of low end, 32-bit offerings (including the large increase in netbooks) and the higher end of 64-bit pros and gamers who will collectively amount to a population not dramatically larger than the Mac installed base, dramatically leveling the competitive playing field in the 64-bit arena.
64-bit Cocoa
Meanwhile, Apple is now arriving back to its original strategy in delivering Cocoa as the primary graphical API for Mac OS X applications. This marks the end of Apple's decade of compatibility appeasement to Adobe and Microsoft, both of whom led a third-party refusal to update existing apps from the old Mac OS routines to the advanced new frameworks Apple acquired from Steve Job's NeXT. Going forward, anyone who wants to deliver 64-bit graphical apps has to build them using a Cocoa interface.
Apple was powerless to force the issue a decade ago, when the Mac platform didn't seem to have much potential left and the new Mac OS X could not offer any guarantees of its survival or success to third party developers. That has all changed. Apple now operates a strong platform that has been rapidly outpacing the growth in generic PC sales by a significant factor for several years now.
Developers now know there is money to be made in shipping third party apps for Mac OS X. Additionally, the tools used to build new Mac apps are essentially identical to those used to develop apps for the iPhone and iPod touch, the leading mobile platform by a wide margin.
Apple's singular focus on Cocoa will greatly simplify the company's development efforts, as it won't be having to move both Cocoa and Carbon into graphical 64-bit land. While Adobe has complained that Apple's decision to freeze Carbon in a 32-bit maintenance mode has prevented it from delivering a 64-bit version of CS4, the simplified Cocoa roadmap will force Adobe to get on the ball with the next release, upgrading Creative Suite in two directions (Cocoa and 64-bit) rather than dragging along the Carbon past into another decade.
Microsoft and other significant Mac developers will also have to get on the Cocoa bandwagon in order to stay relevant on Apple's 64-bit Mac platform for the next decade. The Mac already has much more visibility, market relevance and software profitability than its market share would suggest, thanks in part to Apple's bold capacity to decisively burn its legacy bridges in order to give developers a single, clear option for future development, just as it did on the iPhone.
Of course, Apple itself needs to deliver 64-bit versions of its own Logic Studio, Final Cut Studio, and Aperture, too. The company was previously outpaced by its third party developers in the move to PowerPC, and to a lesser extent, in the move to Intel Macs. Apple's position as both a platform vendor and an application developer should help it to deliver practical, usable tools for its own developers.
Apple's leadership in laying out a strong 64-bit future in Snow Leopard has created a strong foundation that will enable the Mac to move ahead in important ways. However, there's more going on in Snow Leopard than just new progress in supporting 64-bit CPUs. The next segment will look at how Apple has pioneered efficient use of GPUs, and what it means for today's Macs and for coming generations.

Apple's site about Snow Leopard says that 64-bit *apps* under Snow Leopard will be more secure than ever due to several things:A more secure function argument-passing mechanism and the use of hardware-based execute disable for heap memory.
Memory on the system heap is marked using strengthened checksums, helping to prevent attacks that rely on corrupting memory.
Nerdly question, but does anyone know if any of these types of security enhancements require the 64-bit *kernel* (not just a given app)? My white Macbook (C2duo) is unlikely to run 64-bit unless Apple lets it in their final release (it apparently won't so far as they haven't written drivers for my lowly machine).
How come I can run 64-bit Windows 7 on my first gen Mac Pro, but I can't run Snow Leopard as completely 64-bit (with the 64-bit kernel). What am I missing here? Is it truly a hardware limitation or is it just a software block that Apple has put on these machines?
I always thought that you couldn't run Snow Leopard 64-bit Kernel because of the EFI32. After installing Windows 7 successfully, it makes me wonder if the inability of running full 64-bit Snow Leopard is just an artificial limitation.
What's the deal? I could be completely wrong about all of this. I'm still confused about the EFI32 thing. Can someone shed some light on this?
Im interested in trying Windows 7 RC, but don't know which version to download. Im planning to install it on a MacBook Pro (May 2008), in Boot Camp and in VM.
It has a 2.4 GHz Intel Core 2 Duo, 2 GB of RAM.
I'm using LogicPro 9, and it runs on 32-bits mode. And I can't seem to find a way to change that to 64-bits.

... long time reader, first time poster!! So I'm doing it. I'm switching from PC to Mac. I've been waiting for a while now and the new MacBook Pro's have convinced me. I'm buying the 13 inch this week.
However I'm slightly worried about the upgrade to Snow Leopard in September.
My question is if I buy a new MacBook Pro this week and upgrade from the current version of Leopard to Snow Leopard will it be the EXACT same as the version of Snow Leopard that ships with new MacBooks after September?
Is the upgrade just the same as the full software version available post September? Does the upgrade it just detect if you have the previous software and installs as if it were the full? Or does it just "patch" things depending on what's different from previous versions?
I can wait till after Snow Leopard is released in September 09 if it is different to Leopard upgraded to Snow Leopard.

I see a lot of people suggesting that perhaps because the poster had less than 10gb (which is my case as well-- I have around 8), that this is why this message is happening. Well, my response to that is:
1)I have had around 8gb free for months, and these messages only started appearing in the last week. Each time I go "???" and look at my finder to see 8.4gb free or whatever, and I am like "WHY ARE YOU TELLING ME I AM OUT OF SPACE?
2)in the terminal, I was trying to download a few 20-30mb files, and wget quit out on me saying "insufficient storage space left on device".and doing "df -h" shows me that I have almost 10% free.. and again this is a 20-30mb, so this is total nonsense.
Are there any suggestions as to what might be causing this and a course of action, other than being told: "copy your files to an external hard drive and delete them on your startup disk".

Nowhere do I find this item on either the OK or Not-OK list for full compatibility - I see references to "Core Duo" and similar but none to "Dual-Core". It seems that Snow Leopard will run but not take full advantage of capabilities. Also it seems that I have the old PCI bus ( it just says PCI no PCI 1 or PCI 2)and old graphics processor (NVIDIA GeForce 7300 GT:) Does anyone know where to get the graphics upgrade kit? B&H which has been suggested elsewhere has none

Anyone noticed when making Combined pdf files (into single document) that Acrobat Pro only shows the first page, and not the full document. Meaning that one has to manually pull the sidebar down to scroll other pages? My install went perfectly, aside from a few minor glitches, Illustrator and Photoshop (CS4) quit now and again, but removed permissions, restarted and repaired permissions and is a lot more manageable now.
Safari and Mail are almost twice as fast now. Let's see how soon 10.6.1 appears.
I waited a long time to upgrade my MacBook to Snow Leopard, mostly because I didn't really need any of the speed increases or other updates, and because I remained concerned about having new bugs in my system. I was always happy with Leopard and never had any issues. I finally did upgrade to SL, and iCal is giving me hell. Its tough to explain the problems that its causing. Basically, the boxes get out of alignment (see attached screenshot), then stuff disappears, sometimes will come back if I click forward a month and then back. If I do this more than one or two times, it just straight up crashes. It is incredibly frustrating. Has anyone else run into similar iCal issues? I feel like a calendar program is one of the more straightforward things Apple has to work on, so I am really surprised that out of everything, this is the biggest upgrade problem I have run into.

My mac HD failed, I had a new one installed. I tried to restore from external TM backup, but it didn't seem to work. I tried two times - the second time, it failed and indicated that I didn't have space on my new drive. My original drive was 320g, new drive is 500g. I had about 80g of data on the new drive. Finder now shows that the new drive has only 25g available (old backup was about 280g). My attempt to restore to my last backup (3/27/2012) didn't seem to work, my old files are not on my new machine.  Â
I'm thinking my best bet is just to undo whatever has been done to my new drive. I don't have a problem formatting the new drive, as there is nothing really on it that must be saved at this point. I am not well versed in Macs (obviously), but I have enough tech sense to follow steps if somebody could offer them. How can I undo this? Should I just format the new HD and do a Snow Leopard install from scratch, and then try again to restore from my time machine backup?Â

One of the drives in our 2009 mac mini server 2009 has died. I have taken apart many minis so have no problem taking it apart to replace, but does anyone know which drive is the primary, "Server HD" drive? Would it be the top drive (first drive you come across during disassembly) or the bottom drive closer to the logic board with the two pads stuck on? Just wondering if anyone knows for sure so I can avoid removing the drive that's still working fine.
Also, to keep the server running in the mean time, I am booting to the second drive which is working fine. Just curious, once the dead primary drive is replaced , can I simply use carbon copy clone to copy back from the 2nd drive, or will I need to install snow leopard server back onto the new drive?
With a sharp fingernail I seem to have damages the internal ribbon cable that connects the audio card in my 2009 Mac Mini, and am looking to source a replacement, preferably in the EU. I'm currently in the UK.The part number is 922-8809.
A Google search reveals a few parts suppliers in Europeland, but they are all charging silly prices for the cable, and US suppliers impose ridiculously high postage charges.
