Determining 64-bit capability

Hi,
Does anyone know if the data collected by SCCM hardware inventory (SCCM 2007 SP2 R2, if that matters) are sufficient to answer the question: "which of my workstations is 64-bit capable?"?
There is a field named 'Is64Bit' in the SCCM extension to the WMI Win32_Processor table. The SCCM SDK describes the field as "A non-zero value if the CPU is 64-bit. Otherwise, this property is set to zero." Is there any documentation as
to what properties or attributes of the processor the inventory agent senses to determine which way to set the bit? We've tried writing a report querying this field but the result returns quite a few systems that are not 64-bit capable.
Anyone solved this one?
Thanks, much.

DataWidth is the attribute from Win32_Processor that I would typically use to determine if this CPU is 64-bit or not.
I think Is64Bit will also get you the info but is not enabled for reporting by default -- its not a big deal to enable it though -- but DataWidth already is being reported and has the data. Also, I'm not sure what populates that attribute.

How to determine the bit rate with button over video subtitles?

I have a project where I've got several questions that come up on the screen. The DVD is subtitled in 14 languages, so depending on the language chosen, it will show the question in the proper language along with navigation buttons to go to the next question or track.
The problem is this: I added several new questions that each have a black only video that runs about 1min with 14 subtitle tracks made from photoshop psds. When I try to build, it fails saying "bit rate too high." When I removed all but 5 of the subtitle tracks, then it would build. I came up with a workaround, but then hit the limit of 99 tracks, menus or stories on a DVD.
I went back and tried combining all 3 questions in to one slide, but now with more information on the psd, it will only allow 3 subtitle tracks before it reaches the max bit rate.
How does it determine the bit rate? What can I do to lower the rate? I tried compressing the video at the lowest bitrate, but it didn't' help. I tried changing the psds to much smaller jpg files, but it didn't change anything. If anyone has any suggestions, please let me know!
Thanks.

CS,
Almost all DVD SP Tracks should first be completely constructed in a Sequence in FCP, the markers placed there, and then everything encoded into a single Mpeg 2 clip with matching length audio (even if just low bit rate AC3 silent audio, as the case may be, because all Mpeg 2 clips in the Title domain should be accompanied by an audio stream), and then imported into DVD SP.
Lay your subtitles under that and see what happens.
Take care,

Why won't 64-bit capable apps run in 64-bit mode under 10.6.8?

have application called Spartan '10, and it is 64-bit capable. i have set it to run in 64-bit mode in the app's preference pane. yet when i use Activity Monitor, it indicates that the app is running in 32-bit mode. is this because of the OS? will upgrading to lion/mtnlion make any difference? thx in advance to all knowledgable responders. btw, the iMac is late 2009, has the 64-bit EFI, and the OS and all related subroutines are running in 64-bit mode, according to Activity Monitor. the Spartan application is about the only thing NOT in 64-bit mode. why is this?

Yes. You have a 64-bit ROM since your model will run Mountain Lion. So, what you want to do is install Mountain Lion which will boot the 64-bit kernel by default. Otherwise: 32- or 64-bit Kernel Startup Mode Selector 1.6.
Note you may have problems in 64-bit kernel mode. Main worry is video drivers that are 32-bit and will not work in the 64-bit kernel. But give it a try. I would just ugrade OS X:
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.

Is my MacbookPro 64 bit capable? It has an Intel Core i7 processor, 8GB of Memory and runs the OSx Lion 10.7.5 system, Want to confirm before I install SW that requires 64 bit. Thanks.

Is my MacBook Pro 64 bit capable?

Yes it is a 64bit CPU and the OS is 64bit.
The worst thing that could happen is the software won't either install or it won't run.

Need help to determine 64 bit vs. 32 bit

Hello,
I recently tried CoolIris for Safari, which forced me to run in 32 bit. I noticed graphic loading problems so I fully uninstalled CoolIris. When I "Get Info" on my Safari Application I do not have the option to run in 32 bit which means I am already running 32 bit. How do I get back to 64 bit???

I hate to sound like a scolding parent, but you've got to realize that deleting things without knowing the consequences is going to create larger problems for you. Stop assuming the problem is the application; it is rarely the problem, so just resist the urge to do that.
If your MacBook was purchased new after April 1 of 2008, it is capable of booting into 64-bit mode; otherwise, it's not. To find out if your model is capable, copy/paste this line in Terminal and press Enter or Return
ioreg -l -p IODeviceTree | grep firmware-abi
it will tell you definitively. Even if your Mac is capable, you will not gain any performance benefit from running in 64-bit mode, since Flash and other Input Managers only run in 32-bit mode; otherwise, they just quit or crash.
As for Safari specifically, you can't download any installer for that; it is only on the Snow Leopard installation disc. You would need to insert the disc, navigate to the Optional Installs folder and launch the Optional Installs.mpkg file. Select Safari as the only item to install and run the installer; quit when done and eject the disc. Then restart your Mac to complete the installation.

New mid-2009 MacBookPro NOT 64-bit capable????

just bought brand new 15" MacBookPro5,3 mid-2009 model.
but it won't run in 64bit because it says it's not 64bit capable EFI and kernel??
how can that be??
what am I missing?

I know it was something that Apple wanted to push as one of the advantages of Snow Leopard... but the whole 64 bit thing has really just caused lots of confusion. They should have just announced it as a step in becoming a fully 64 bit OS. Lots of people now think they're missing out on something or not getting the best performance when their machines are not running in 64 bit mode... when in effect, no one would really ever notice any difference. It has also caused confusion with respect to RAM capacities. Many people were under the impression that if their machine was limited to 4GB or less of RAM that moving to Snow Leopard would let them access more RAM (which is generally the biggest touted advantage of a 64 bit OS). Even under Leopard, the latest notebooks were able to have up to 8GB installed... and MacPros under Leopard could support up to 32GB.
To be honest, the average user has no real understanding of the differences between 32 and 64 bit. But just like everything else... they see 64 is 2x 32... so it must automatically be better. It will be a while before there are many apps that are specifically developed for 64 bits. Even in the Windows world where 64 bit versions of XP and Vista have been around for years, there are very few 64 bit apps... and considering the giant market share they have, if there was a real need to move in that direction, you would have seen a lot more development for 64 bit apps. It's going to happen eventually... but by that time, it's safe to say that the 64 bit capabilities of Snow Leopard (or what ever version of the OS is out then) will be fully implemented.

How do I determine what bit encription Firefox is running at.

Am I running 128 bit encription or something else?

Firefox supports up to 256 bit encryption. To find out what encryption a site is using, click on the site identity button ([https://support.mozilla.com/kb/Site+Identity+Button]), then click on the "More information" button. The security section gives details about the encryption in use.

I ordered the CS5.5 Design Premium, and InDesign will not install because, although my computer is 64 bit capable, it is currently set at 32 bit. Is there a way I can create a custom installation that will allow me to install products that require a 64 bi

Any guidance would be greatly appreciated. I am financially impaired (nice way of saying "poor"), and cannot afford to purchase any more upgrades for my system or another version of InDesign.
I am sure there must be settings that will allow me to install the program, possibly with limited functionality due to this issue. I am disabled and cannot work outside of my home. I was hoping to make a small income freelancing with this package, and InDesign is a crucial part of the package.
Thank you very much for any assistance.

So I would have to uninstall Windows 7 Home Premium and reinstall it as 64-bit? I'm trying to do this without having to reformat my computer. Is there a way I could create a 64-bit partition on my secondary hard drive without reinstalling the OS?

How do i determine if my processor is processor is 32 or 64 bit ? ?

have already looked in the "about this mac" section but can't find anything there. the only thing it tells me is: 2.3 GHz intel core i7. how do i determine if it's 32 or 64 bit ?? any hellp app.

Hi, i7s are 64 bit, also, 10.7/10.8 will only run on 64 bit capable Macs.
Core 2 Duo, i3, i5, & i7 are all 64 bit Intel CPUs.

Can Mac mini boot into 64-bit kernel

http://macperformanceguide.com/SnowLeopard-64bit.html says:
To determine if your Mac has 32-bit or 64-bit firmware, copy/paste the following command into Terminal:
ioreg -l -p IODeviceTree | grep firmware-abi
...output:
| | "firmware-abi" = <EFI64>
As shown above, the firmware-abi has the value EFI64, indicating that my Mac Pro is 64-bit capable. If it reads EFI32, then your Mac cannot be booted into a 64-bit kernel.
...well, my Mac mini displays that EFI64 64-bit info, but when booting with the "64" keys down it nevertheless uses the 32-bit kernel.
So can the Mac mini boot into 64-bit kernel?

What you are missing is that Apple has written into the boot ROM for certain Macs which meet the criteria to not be able to boot with the 64-bit kernel. The Mac mini is not allowed to boot into 64-bit mode by Apple. There is a list of non-pro Macs hard coded into the EFI boot firmware that tells it not to allow these Macs to boot into 64-bit mode. The Mac mini is on the list! Try as you may the Mac mini will not do it without a hack.
If you google this issue you can find a hack to rewrite the boot firmware and allow the mini to boot into 64-bit mode. It can be dangerous to your mini if you make a mistake!
Here is one hack;

What CC Applications are still only 32-bit?

Is there some way to determine whether a given Creative Cloud application is still only 32-bit? I mean other than creating a 64-bit package and looking to see if it installs to Program Files or Program Files (x86)? That's what I've been doing, but I've since discovered after re-packaging Photoshop and installing it on a test system, that it's now available as 64-bit application. Can I get notified of changes like this?

Hi jpt65,
Which desktop applications in Creative Cloud require 64-bit operating systems?
With the new CC apps, most of the pro video and audio applications now require 64-bit operating systems to run. These native 64-bit applications include Adobe Premiere® Pro CC, Adobe Audition® CC, After Effects® CC, Prelude® CC, and SpeedGrade® CC. Photoshop CC and Lightroom® also require 64-bit on Mac OS.
Why is Adobe switching some of its applications to a native 64-bit architecture?
By optimizing code for 64-bit operating systems, Adobe is able to deliver the performance gains that creative professionals require. Most of Adobe's pro video applications now require a 64-bit operating system, but the majority of video professionals have already transitioned to 64-bit capable systems, such as Mac OS X v10.7 (Lion) or v10.8 (Mountain Lion), or 64-bit versions of Microsoft® Windows® 7 or Windows 8. Because 64-bit operating systems offer superior performance, current and future releases of most of the Adobe professional video and audio applications will not support 32-bit operating systems.

Install Windows 7 64-Bit on Early 2008 Macbook ?'s

My wife has an early 2008 Macbook with 2.4 GHz processor that I recently upgraded the OS to OS X 10.7.5 and upped the ram to 4 GB. I had installed a Boot Camp for Windows Vista 32-bit that is still working, but I have a Windows 7 64-bit installation disc that I would like to use on this machine. I want to completely delete the existing Windows Vista install and put Windows 7 in its place. I have found through my research that even though the 64-bit version of Windows 7 is "not supported" for this machine, it will still work with the right drivers and will require Boot Camp 4.0
My questions are:
- Will the 64-bit version of Windows 7 definitely work on this machine?
- How would I delete the current Windows Vista installation?
- Where do I get the 64-bit Apple drivers for Windows 7? I keep reading about pulling them from the Snow Leopard install DVD, which I have, but I am currently running OS X Lion on the machine, which I do not have a disc for (only received a download code from Apple). Would the drivers be built-in to Boot Camp 4.0?

Lightroom crashes when rendering Develop preview under Vista 64-bit

I'm running Windows Vista Ultimate 64-bit and Lightroom 1.1 crashes every time I click the "Develop" pane. My images are DNG files without the original RAW embedded.
Lightroom ONLY crashes when I load an image in Develop. If I open Develop without any image selected, it's fine (no image is displayed). I can zoom in to 100% in Library and it works fine. Exporting images to JPG works fine. Editing photos in the Library pane is fine. The crash data is:
Problem signature:
Problem Event Name: APPCRASH
Application Name: lightroom.exe
Application Version: 1.1.0.0
Application Timestamp: 4677e8e1
Fault Module Name: MFC80U.DLL

I've uninstalled LR 1.1 and reinstalled and it does the same thing. When I uninstall LR 1.1 and the install LR 1.0 (the previous version) Develop does open, but it doesn't render the images correctly - it looks like it misinterprets the white balance by about 1,500k degrees (very ugly), but Library shows the correct image/white-balance.
I've updated my nVidia 7900 graphics drivers to the latest version, appropriate to my OS and architecture. I've disabled XMP creation and Adobe Photo Downloader, as well as all other running applications (Antivirus, spyware, itunes, etc).
This USED to work fine in Vista and I did not make any significant changes, but I expect it's an issue with WindowsUpdate causing an incompatibility. I can't roll-back to my Vista state when it worked a month ago (that's another Vista frustration).
Anyway advice or comments would be GREATLY appreciated since this is an integral part of my professional workflow. I own a legitimate, licensed copy of both Lightroom and Vista, yet neither company is willing to talk to me unless I pay them money, which I think is complete extortion, but I digress.
Thanks in advance for your help.

Has anyone got a resolution on this? I have the same issue. Lightroom crashes when I click develop and the develop module begins to render the image. Clicking develop with no image selected allows the develop module to load however selecting develop on the menu bar and choosing either previous photo or next photo causes lightroom to crash while rendering an image.
I have a 64 bit capable HP XW8400 workstation with 2 dual core Xeon processors, 4 GB RAM, and a nVidia FX 4400 graphics card. This video card was put in as a test. the original video card was an nVidia quadra NVS something. When I ran the NVS card I used the drivers certified for Adobe CS2. I am running 32 bit Windows XP SP2 with all current updates. I do not have any MS office components installed on this system.
I read of some troubles around the Realtek HD audio driver and some Adobe applications (not Lightroom). Since I have this sound device I disabled it and removed the drivers...still crashes.
I also disabled the Intel VT in the system bios (I believe this is required to run 64 bit XP or Vista)... no change. Also disabled the NX feature...no change.
I also loaded VMware workstation 6.0 and installed Lightroom in a 32bit Windows XP SP2 VM. In the VM Lightroom works perfectly on the same machine...just not as snappy...
This stinks...Lightroom works perfectly on my poky laptop.

A late 2007 Mac Pro (2,1) no longer boots into 64-bit Snow Leopard

In Snow Leopard 10.6.7, my late 2007 Mac Pro (2,1/3.0 GHz/Dual Quad-Core Intel Xeon) no longer seems to be booting into 64-bit mode. I've tried holding down the 6 and 4 keys during startup and even used a Terminal sudo command to force the machine to always boot into 64-bit mode. No matter what I try, an About This Mac>More Info>Software check only reports the following:
     64-bit Kernel and Extensions: No
Before I upgraded from Leopard 10.5 to Snow Leopard 10.6, I carefully researched this, and this Mac Pro model specifically was listed by Apple as being capable of 64-bit booting — meaning that it would utilize at least some extra memory. At the time, under OS 10.5 and early versions of 10.6, when I used this Terminal command...
     ioreg -l -p IODeviceTree | grep firmware-abi
...my Mac Pro 2,1 returned this response:
     "firmware-abi" = <"EFI64">
As a result of my tests and research, I upgraded the installed SDRAM from 4MB to the theoretical maximum Apple indicated this model could support (16MB) so that Adobe Photoshop 12 (CS 5) would fully utilize extra installed memory under Snow Leopard. While using the first versions of 10.6 Snow Leopard, the machine worked fine in 64-bit mode. Now, in the wake of the 10.6.6 or the 10.6.7 update (I didn't notice which), I find that this model no longer even reports itself as being 64-bit capable, though it once did.
Now, the aforementioned Terminal query returns this response:
      "firmware-abi" = <"EFI32">
Also, the Library>Preferences folder does even not contain a file called "com.apple.boot.plist," which some owners have reported editing to force 64-bit booting.
The thing is, I spent a fair amount of money upgrading this machine to the maximum amount of SDRAM supported. I purchased it because it was advertised as being 64-bit capable and I upgraded it because Apple originally reported it as being a 64-bit model. Now, I'm not sure if the extra memory I added is being fully utilized, though Photoshop does report seeing 15547MB of available memory.
Have any other owners of these second-generation Intel Mac Pro's encountered this? Does anyone know what's going on? Am I doing something wrong when checking for the 64-bit installation or architecture? Is Snow Leopard 10.6.7 mis-reporting the architecture for this model? Or did Apple silently withdraw 64-bit support for this machine in a recent OS update?

Hatter: Thanks for the feedback and links. Well, as described in one of the threads you linked to, the document below reinforces your assertion that only Mac Pro's 3,1 or later (early 2008) support 64-bit booting in Snow Leopard:
http://support.apple.com/kb/HT3770
However, if you asked me in court, I would swear on a stack of Bibles that sometime in the past, I read an Apple document indicating that the Mac Pro 2,1 supported 64-bit booting and I really thought I recalled booting this particular machine into 64-bit mode under early versions of Snow Leopard.
I guess I'm mistaken. Certainly, this issue can be confusing. When I read them out loud to myself, even perfectly-written, accurate explanations on the subject can sound like a circular, non-sensical George Bush rationalization being delivered by comic Will Ferrell. I must not be correctly recalling the details of booting into 64-bit mode with this machine. And I guess that since Photoshop has its own memory management scheme, and I only have 16 gigabytes of SDRAM installed anyway, it doesn't matter that much. Furthermore, in one of your links, Jason Snell of Macworld writes:
"...If you’re running a Mac powered by an Intel Core 2 Duo processor or an Intel Xeon processor, your Mac is 64-bit capable. And Snow Leopard runs 64-bit-capable applications in 64-bit mode regardless of whether it’s booting into a 64-bit or 32-bit kernel. In fact, the only big advantage of booting into a 64-bit kernel would be the ability to use more than 32 gigabytes of RAM..."

Some Solutions, 1 remaining prob with MBP, Windows 7 64-bit, Bootcamp

It has taken me about 3 months to get Windows 7 64-bit (OEM disk purchased from TigerDirect) to work on my MacBook PRO 17" 2.4GHz, and it is still not quite there.
FIRST: It seemed impossible to load. I put the disk in the drive, held Option key down, selected Windows (from the DVD), and was presented with a black screen with white writing that said: 1. 2. Select Boot Type. That would be it. No response from the keyboard or even a USB keyboard. I read about an incompatibility with EFI naming conventions between Apple and Microsoft. Something about naming conventions. The solution is elsewhere in these discussions and involves re-creating the Windows install DVD with an EFI naming convention that apple likes. That worked, and the re-burned Windows disk booted! Hurrah?? No.
NEXT: The installation process started - all the correct Windows screens popped up, but it was incredibly slow. In fact, the installation process took 24 hours (YES!) to complete. Once it was done, I rebooted. The flying orbs started. I was excited! But instead of a login screen, I was presented with a black screen and a movable white mouse cursor, and that was it. I left it on this screen for 24 hours, with no change whatsoever. No sound. No response to CTL-ALT-DELETE. No response to holding the shift key down or pressing it 5 times - all things recommended by some folks who were able to pull up taskmgr this way and launch Explorer. For me, this was not possible. Nothing worked.
NEXT: I thought I'd check to see if Windows 7 64-bit really installed on the bootcamp partition. I did this by firing up Parallels 5 and pointing it at the bootcamp partition, where it found Windows and cheerfully offered to boot it for me. It worked, but this is not what I wanted. Still, it was enough to prove to me that the install was complete, valid, and bootable.
Months passed with trying various things.
Finally, I read about something involving memory. I fired up parallels, went to a dos prompt in my Windows 7 install thanks to Parallels access to it, and typed MSCONFIG. There's a boot tab there, and when you click on Advanced, you'll see a Maximum Memory box. Type a number in here like 2000 or 3000 (I have 8GB RAM installed, so I typed in 4000) and applied the change, then shut down windows in Parallells. Then, I restarted my mac and booted into Windows. Guess what??!? It BOOTED!! Now, all memory tests tell me that all 8GB of my RAM are fine. I swapped the two DIMMS and no change, so one DIMM is not bad. My EFI is 64-bit capable. My Windows version is 64-bit. So, when I right click on My Computer, select Properties, and read the screen it says: MEMORY: 8GB installed, 2.97GB usable. Now, I understand that some of the 4GB is used up by devices so I get this 2.97 number, but what gives??
So this is where I need some brilliant guy's help: What's the deal with the RAM? If I type a number above 4000 in the box in Windows, I can go up to about 4080 but after that, the number won't stick (goes to 2 or 3 or something crazy). Again - EVERYTHING is 64-bit: The EFI, the Windows 7 install, and my MBP is one of the supported ones. So what on earth could be the problem?
(Oh, and yes, I loaded the Bootcamp 2.2 drivers from my Snow Leopard DVD, then loaded the Bootcamp 3.1 updates and drivers, yes my Magic Mouse works, yes the screen is perfect, yes I do have sound, yes Windows Properties says it's Windows 7 64-bit, but I do have the heat problem mentioned elsewhere in these forums.)
Your thoughts would be very appreciated!

I'm looking into running Windows 7 64bit on the exact same MBP you have, so I'm curious as to whether or not you've found a solution yet outside of the forums.
Do you think it might be that the bootcamp 3.1 update is only for Windows 7 32bit and not for the 64bit version?
