Is my Mac Pro 64 bit?

I bought my mac pro in October 2007 and I didn't think about it at the time, since I had nothing that was 64 bit, but I am wonder how you can tell if the machine is 32 bit or 64 bit. I am starting to see more 64 bit programs and I am just wondering what I have since I don't remember the specs when I bought it and I am not seeing it in "about this mac." Thanks

All Intel Macs except the early Core Duo laptops and Minis are 64-bit. Leopard is also a 64-bit operating system.

Windows XP Pro (32-bit) and Vista Ultimate (64-bit) on the same Mac Pro HD?

Has anyone been able to install both Windows XP Pro (32-bit) and Windows Vista Ultimate (64-bit) on the same dedicated Windows hard drive? I have four HD in my Mac Pro, and one of them is dedicated for Windows (and bootable via Boot Camp). I found the following technical articles about installing Windows XP & Vista on the same hard drive (using two separate partitions) using a VMWare machine as the test system:

Has anyone successfully installed Windows XP (32-bit) and Vista 64-bit) on the same NTFS partition?
I already have Windows XP Pro (32-bit) SP3 installed on my single NTFS hard drive. I am looking for the best way to add the Vista 64-bit installation on the same hard drive.
Any thoughts and advise are appreciated.

Windows has its own list of boot OSs, and default, from msconfig. It will sit and wait for xx-seconds on startup in Windows if you want to boot from an alternate.
As to whether Apple's OS Switcher (aka startup disk bootcamp control panel or tray icon) sees both, I had Windows Home Premium and Ultimate 64, and pretty sure OS X saw both. That was pre-Leopard and before there were 64-bit Apple drivers.
I can't think of any scenerio of wanting to mix 32-bit and 64-bit on the same paritition, you realize you can't install the one over the other and must do a clean install.
When I added a partition out of main partition (I wanted to put search index and page file on their own partition) those partitions aren't seen - are hidden - to Leopard.

Do I need a 64 bit processor on my Mac Pro to run CS6 and Lightroom 4?

I would like to install Adobe CS6 and Lightroom 4 on my 2008 Mac Pro but may not have the right processor to run it. I know I will have to upgrade my OS X 10.5.8 to at least OS X 10.6.8. The system requirements specify a Multicore Intel processor with 64-bit support. I have a Quad-Core Intel Xeon processor. Does this mean my Mac will not run this software at all or slowly at best? Will I only be able to use this software if I buy a new computer?
Here is what I have now:
Hardware Overview:
Model Name:          Mac Pro
Model Identifier:          MacPro3,1

Please see the tech specs for LR 4 : http://www.adobe.com/products/photoshop-lightroom/tech-specs.html
LR 4 and CS 6 applications will not run on 10.5.8, you need atleast 10.6.8 to run these applications.

Vista Business 64-bit Mac Pro 2.66 4-core

Hi,
Before 10.5 release, I tried to install Vista Business 64-bit twice, Erasing and starting from scratch both times (on a dedicated internal hard drive).
Both times I had driver issues...I eventually Erased a 3rd time and went with 32-bit.
I learned today Apple is now supporting 64-bit at least on some later 2007 Mac Pro models.
My 4-core 2.66 is April 2007.
MY QUESTION:
Does 64-bit work on a Mac Prow tower 2.66Ghz, 4-core (10gb ram)?
(I'm not brave enough to try it on my 8-core).
Will Windows Bootcamp SOFTWARE UPDATE give me all the required drivers -- no basic issues that would waste my time again trying to make 64bit work?
+++++
Note: I have the Tiger 10.4 OEM disks and a retail Leopard 10.5.0 install disk to work with.
I also have both 64 and 32 bit disks for Vista Business.
Is there a trick to doing this?

I'm done for today, but there was only one trip-up, getting the 2008 64-bit Apple drivers.
I started with Vista RC1 two years ago, and no major deal breakers in the last year or so (late '07 seemed to clear up most driver and applications).
Format drive as MBR and NTFS (and skip using BootCamp Assistant).
Install.
Update.
Install Apple drivers.
Don't install what you don't need (I learned to avoid Norton).
I've used Business, Home Premium and Ultimate, all 64-bit.
If you have a 2008, then use its OEM DVD for BootCamp 2.01 64-bit, you need those sort of for HAL and stuff. The 2008 officially supports 64-bit due to its EFI64 ROM is UEFI 2.01+.

I am going to buy either a Mac Air or Mac Pro Retina 8GB RAM and 256GB. And as I have to still run Windows I will install Parallels 9. As the Mac are both 64bit machines does that mean I need to install Windows 7 64bit ? And office pro 2013 64 bit too?

I am going to buy either a Mac Air or Mac Pro Retina 8GB RAM and 256GB. And as I have to still run Windows programs I will install Parallels 9. As the Mac are both 64bit machines does that mean I need to install Windows 7 64bit or just install 32 bit? (Going with Win7 as I hate Win8). And I will install Office Pro 2013 64 bit too or 32 bit or is that automatically selected by the underlying OS (I use Word, Excel and Access mainly for a membership database of a local club) ? I am not a power user so would appreciate advice on way to go

Again thank you. If I only use word, excel and access in the Win environment and Mac OS for email and safari for internet do I need anti virus software . Ie my connection to the world is mac only and I use office pro only to ruin the club, newsletters, membership database etc. and of course anything I do there can drag/drop to the mac environ to email. That's my understanding anyway. Next will my existing .pst file copy directly into mac mail or do I have to runs translator as I recall reading something about that ages ago when I started thinking Mac

Windows Vista 64 bit w/older 2 dual core 3.0ghz Mac Pro with NVIDIA 7300

I have read a variety of the posts that have appeared here on the use of Windows Vista 64 bits on a Mac Pro. I remain confused, and but want to do this. I have a Mac Pro purchased in the Spring of '07 with dual 3.0Ghz dual core Xeon cpus and 10gb of ram, using the NVIDIA GeForce 7300 GT and running 10.5.1, with multiple drives. I want to run the 64 bit version of Vista Ultimate to use my ram, and to gain the performance this box should offer. It appears that I have three options:
1. Boot Camp: I don't know if the drivers are available, seems like the new Mac Pro drivers probably would not work, even if I could find them, since I have an older Mac Pro with a pair of the dual core Xeon CPUs. Don't know if there is an alternate source than Apple for the drivers, or a way to get around the problem in boot camp.
2. Parallels: I do not believe that 64 bit apps are supported by Parallels
3. Fusion: Their web site says they support Win Vista 64 bit, but it is not clear to me on the web site where the drivers are obtained, or perhaps they are built in to Fusion. Will I get the performance and memory benefits in fusion? Or is the OSX virtual overhead so high that this is a fools errand?
I do a lot of video editing, and fully 95% of my life is in the Mac world, but I have individuals who send files for editing, and occasionally they require Windows tools, much to my chagrin. I also have a small number of programs that need Windows 64. I occasionally am required to do some development work, and would like to use this machine for that purpose if it can indeed run Win Vista 64bit. I have XP loaded on a more modest box andit is running fine when I need it, which isn't very often.
Any help, or successful experience in running Windows Ultimate 64 bit on this hardware, utilizing its resources would be greatly appreciated.

Here are my results after further digging online and from my own experience.
Here is the procedure:
1. Check whether your Mac has the 32-bit EFI or 64-bit EFI
http://www.ihackintosh.com/2009/08/snow-leopard-106-and-64-bit-what-you-need-to- know/
2. Create a Boot Camp (BC) partition for Windows 7 x64. Resize the partition size using the slider in the BC app. Follow the instruction, insert the Windows 7 disk and reboot.
3. This will load the PC partition which is FAT formatted for now. Choose the Boot Camp partition on which to install Win 7, but choose in the option to format that partition. It will automatically format it in NTFS. Otherwise, it will not install on that partition.
Note : A "OEM System Builder" Windows 7 64-bit Professional UPGRADE install without any issues what so ever. The upgrade disk is a full install. Read this for further information:
http://www.pcworld.com/article/174288/windows7_upgrade_madecheaper.html
4. Run windows, then insert the Snow Leopard disk. It will tell you your hardware cannot support x64 version. Do the following procedure to manually install the driver:

5. Then update Boot camp using Apple Software Update in Windows.
6. All hardware works fine except the sound. The sound only comes out of the internal speaker, even when headphone or speakers are plugged in the jack. Installing the Realtek High Definition Audio Codecs driver in order to fixe the problem. Shutdown and reboot to make it applicable. Try a second time if it still does not work:

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..."

Windows 7 64 bit on Mac Pro Ver 1.1 installation options!

Hi All, There seems to be a lot of concern that Win 7 wont run on MP V:1.1. I have this MP and do want to install Win 7 on it.
My Spec is as follows:
Mac Pro (2 x 2.66GHz Dual Core Intel Xeon) Ver 1.1. HD4870 Graphics Card and a 24" Dell U2410 Display. My O/S is Lion.
Question: Will it work installed using Lion's Boot Camp on a freshly formated hard drive?
Question. If Boot Camp is the problem can I install Windows 7 as a totally independent O/S on freshly formated hard drive on my Mac Pro by pulling the Lion O/S out making it exclusively a Windows Pc?
This option, if possible would be very inconvenient as I suppose I would have to remove the Hard Drive containing the Lion O/S every time I wanted to use Win 7?
Can anyone advise me please

I just thought I would share my Mac Pro 1.1 experience. I recently had to replace a failed memory riser card by buying a pair from ebay (they both failed a month apart) and took advantage of the opportunity to replace my Mac Pro 2006 with the 2008 model for $700 and inserted my drives and upgraded to 10.8.5. Just holding off on Mavericks for now... Bought a Radeon 5770 and graphics are just peachy (i'm not a gamer). Then I put a samsung ssd 512gb in as the system drive and a 3tb for data so that machine is going fine
What to do with the 2006 Mac Pro?. No one wants it on ebay so I thought i'd try it on Windows. Windows 32bit loads via boot camp once you figure out how to recognise the sata bus (depends on your windows 7 dvd version i think) but under 32 bit you only get 2gb usable ram ! something , not just video is addressing 2gb so that *****. You cannot boot off the 64bit dvd (try it) so i installed 64bit windows 7 on a clean drive on my core2dou pc then put the drive in my 4core xeon mac pro. It booted fine and installed alot of drivers for the xeons automatically. Then I got some drivers from 64bit bootcamp and sound drivers from the realtek website. Then , I upgraded to 64 bit windows 8 pro and everything still works. Then, I downloaded the free windows 8.1 pro update and everything still works..... As PCs go, this is still a pretty fast machine, and gives little away to , say an i5 or i7. If you put in an SSD and gamers video card it would fly, but i dont need that....

Help Installing Windows 7 64 Bit on Early Mac Pro

As previously noted, Wind 7 RC 64 bit DVD will not boot on early Mac Pro. I installed Win 7 64 bit on a dedicated hard drive as follows: 1) I booted into Vista 64bit successfully 2) I installed Win 7 64 bit on a second black disk, as noted above 3)All files installed correctly I think since Win 7 will begin to boot showing the Windows 7 startup screen 4) However, the startup screen will then disappear and the screen goes black, indicating a failed boot. When I engage the option screen (with primary Mac drive installed) during boot, no Windows disk is shown, indicating that boot camp does not recognize the Win 7 disk as a valid startup drive.
Has anyone successfully installed Win 7 64 bit on an early Mac Pro?? I would appreciate any help in accomplishing this. Also, is there any reason Apple has not provided an EFI firmware update for first generation MacPros?

Burn a DVD with Windows 7 RC 32-bit which you can boot from.
Try Safe Boot also.
From Vista you can install 7 on another hard drive. You can also copy the DVD to 6GB partition and run the install setup off that while in Vista.
Mixing ATI and Nvidia probably still doesn't work (may when 7 ships).
Windows is more aware of disk I/O errors than Mac OS.
Keep your system basic, don't have anything connected or installed you don't need (like PCIe controllers).
Vista SP1 or later, 64-bit also looks for EFI64/UEFI 2.x which causes the "Choose 1 or 2" boot menu and which 2008 Mac Pro (and 2009) work with.
You aren't the first or only person to run into this, and there are people running on 2006 Mac Pro.

Installing Windows 7 64 Bit Upgrade on a Multi-disk Mac Pro

A lot of the information I found to help me with this issue scattered all around so I thought I'd consolidate it in one place.
The situation: I wanted to install Windows 7 Home Premium 64 Bit on my boot camp partition. Windows Vista Ultimate 32 bit was already installed.
My System:
Mac Pro (early 2008)
2x Quad Core 3.0GHZ Zeon Processors
12GB Ram
3x 500GB Hard Drives
OS X 10.6.2
Boot Camp Assistant: 3.0.1
The Issues:
1.You cannot directly update a previous 32 bit installation with a 64 bit installation. You have to do a clean install.
2.If you do a clean install with an upgrade disk it will most likely not activate.
3.Windows 7 does not like more than 4 partitions. More than 4 it will fail to install.
4.Windows 7 does not like GPT (GUID Partition Table) disks and will fail to install if it detects one.
What worked for me after a fair number of false starts:
1.Put the Windows 7 Installation disk in your DVD drive.
2.Start Boot Camp Assistant and create a Boot Camp partition. I deleted my old Boot Camp partition prior to beginning. *DO NOT* start the install from the Boot Camp assistant. Once you create the Boot Camp Partition close the assistant.
3.Power down your computer. (Remember the Windows DVD is in the drive, leave it there.)
4.Remove any extraneous drives that are GPT or cause you to have more than 4 partitions. I installed on my second hard drive and removed the 1st and 3rd.
5.Restart your Mac holding down the “c” key to make it boot from the Windows install disk that is in the DVD drive.
6.Once the Windows Installer is active do a “Custom” installation.
7.Use the Installer utilities to format the Boot Camp partition as NTFS.
8.Install Windows 7 on that partition, but do not try to activate it at this time.
9.When Windows restarts you may have to hold down the “Option” key (Alt if you are using a PC Keyboard) and select the Windows restart disk.
10.Once you boot into Windows do all of the updates.
11.Once the updates are done, make sure you are booted into Windows and call Microsoft support and explain the issue (doing a clean installation with an upgrade disk.) The issue is very common and not specific to Mac users so they will pass you to Tech support and help you activate your copy of Windows.
12.Download (from Windows) the Boot Camp update and install it.
13.You should be fine at this point, at least I sincerely hope so
14. I also had a sound issue but that was resolved by downloading the latest Realtek HD Audtio Manager and wiggling the sound jack where my stereo system was plugged in, the RCA jack in the back of the system.
(Note: I haven't been able to locate my Boot Camp program or tray like I had on my Vista installation. I' haven't really looked. It isn't that big a hassle to hold down the “Option” key when I restart and just pick the OS I want to boot into.)
I hope this helps anyone that is having issues similar to what I experienced.

Not always. I tried. Easier to reinstall Windows 7 over itself, activated fine. Or just do the legal thing and buy full copy. Mac Pro owners that want dual processor support need Pro or Ultimate (Enterprise also) rather than Home Premium.
I would NOT use Boot Camp 3.1, it causes problems for number of Mac Pro owners, though maybe not all so unclear what/why) but just stay with Boot Camp 3.0x from the Snow Leopard DVD (which can have trouble with AppleHFS)

Windows 7 beta, 64-bit, on a Mac Pro

I'm about to attempt this, so I thought I'd gather together some tips on it. Found this thread re MacBook Pros:
http://ourcoffeestops.com/2009/01/guide-windows-7-x64-build-7000-on-a-macbook-pr o/
Has anybody else tried this on a Mac Pro with any success?
I've got a GEForce 8800 GT, early-2008 Mac Pro with 2 x Quad core. Any advice?
Thanks

If you had installed Vista, they you probably know most all the how and why, and just need tips on what is new and different.
Main new item to be aware of:
Older driver updates and installers (like Apple Boot Camp) have to run in a new "Vista Compatibile Mode" property setting. It may not run, or run and not really be successful.
You will need to reinstall or install RealTek audio driver yourself.
Pull your drives and leave one raw drive in there, formatted as Master Boot Record and FAT (MSDOS) and boot from the Windows 7 DVD you burned earlier in Disk Utility.
If someone has a Mac Pro from pre-2008, it has a different EFI32 firmware, not UEFI 2.x (EFI64) and may see an EFI boot menu when first boot from Windows 7 DVD (or Vista SP1 or later) when using 64-bit (Microsoft added some support for EFI in 64-bit versions post Vista SP1).

With Boot Camp, should I install the 64 bit version of Windows 7 (Home Premium edition) OR the 32 bit version when installing onto an early 2008 Mac Pro operating OSX Lion with a 1 TByte internal HDD?

With an early 2008 Mac Pro I'm about to add a second internal drive (1 TByte SATA) and initially install OSX Lion onto the new drive. Then to partition this new HDD via Boot camp. But my question is whether I am best advised to purchase the 64 bit version of Windows 7 (Home Premium) or the 32 bit version of Windows 7 (Home Premium) for the Windows sector of the disk What are the differences, and will I notice a difference in performance?

In chart from wiki, (scroll down to "Comparison chart") check the maximum CPUs supported.
You don't see this on MSoft's 1st searched for chart hit. This is one reason you will regret not paying for Professional+ if you get Home Premium 64 as I did for Mac Pro early 2008.
Home Prem Task Mgr sees 4 processors vs. the 8 that are seen by Pro+.
Costs more than a Mac upgrade to Lion if you make that mistake.

64 bit OS and Applications for Mac Pro

I was all set to replace my ailing G5 PM with a MBP when Apple released the Mac Pros today. I originally bought the G5 because I wanted to be able to run 64 bit software when that became the standard. With the switch to 32 bit Intel chips, I thought that was no longer a concern. With Woodcrest chips in the Mac Pro, however, I guess it is.
When the 64 bit Leopard is released and developers also release 64 bit software, will it all run on the 32 bit MBPs? Apple has said that the 64 bit machines will run 32 bit software side-by-side, but I am worried about compatability in the other direction.
Dual 2.0 G5 Mac OS X (10.4.6)

I'm an active ADC member, paid developer account through for work, though I do not believe it's up on ADC yet to download for dvelopers as preview release. It would be in the next week or so i'd think once they get it out to the higher-priority accounts/users. Apple was giving out a developer preview with all technologies and xcode3.0 and do-ddads to attendees at wwdc today after the keynote. i was lucky enough to be attending wwdc for work with my boss and another employee (at first i 'uged' it, but it is great so far! can't wait for tomorrow).
basicly you are right, its developer only (apple obviosuly and soon ADC members) as well as the dev preview that was handed otu at wwdc today

Installing Windows 7 64-Bit Using BootCamp on Mac Pro 2,1 (Early 2007)

Hi everybody,
I have Mac Pro 2,1 (early 2007) 8-core, my OS X is 10.6.4, I couldn’t install Windows 7 64-Bit on BootCamp separate drive (as my Mac Pro 2,1 is not supported for this installation by Apple). I am seeking help if anyone find a trick to do that task. Your help on this will be highly appreciated.

I was waiting to see if the original poster was still intent on going through with it, since it's (a) lot of work, and (b) an unsupported configuration. Unless he's using > 4GB of memory I'm not sure why he needs the 64 bit version of Win7 (there's even less reason to run 64-bit Windows as a VM). I'm not prepared to assume the responsiblity of solving any/all current and future problems he may run into, especially if this is for "work" and not a hobby-level, "I just want Win7-64bit" situation. If he's reading this and wants to proceed -
The Jowie page, while workable, requires a more steps (i.e. even more work); plus, the screenshots used are from an earlier release of imgburn, which has different options from the current version, and if the original poster needs that much handholding he could be put off.
Win7 AIK is "needed" because of the oscdimg.exe that is included. It is the "official Microsoft sanctioned" way of generating Windows ISO images. It's a one-line command that outputs an ISO image file once you have the Win7 disc in the drive, no need to muck about checking/unchecking boxes etc., and running the risk of burning coasters (since there's no way of knowing whether your output works until you actually run it, and imgburn has too many ways of messing up when you don't know what you're doing).
There are alternate "direct" sources for oscdimg.exe, which are smaller downloads than Win7 AIK http://www.microsoft.com/downloads/en/details.aspx?FamilyID=696dd665-9f76-4177-a 811-39c26d3b3b34&displaylang=en , but I'm a little chary of "programs sourced from unidentified hosts", even though I'm certain most of them are just being helpful and are not malicious (have you read Ken Thompson's Reflections on Trusting Trust - http://cm.bell-labs.com/who/ken/trust.html )
If the original poster (or anyone else reading) is interested, either the jowie.com method can be used, if you are averse to a command line or have poor download bandwidth, or you can get oscdimg.exe (however you choose to do so) and execute:
oscdimg -n -m -bd:\boot\etfsboot.com d:\ c:\iso\win7dvd.iso
assuming oscdimg.exe is in your path (or your current directory), and you've created a directory c:\iso
Incidentally, after getting 64-bit Win7 installed your problems aren't over yet, because Boot Camp will refuse to install the 64 bit version on your "unsupported" machine. There is a workaround (see my post in the thread http://discussions.apple.com/thread.jspa?threadID=2589967&tstart=0 ) but I do not know if there will be a future release of Boot Camp that would defeat this.

Is my Mac Pro 64 bit?
