Mac Pro (generation 2.1) not booting in 64 Bit under SL

Is Apple planning to upgrade the EFI for older Mac Pro in order to make them compatible with 64bit architecture ????
Running a version 2.1 Mac Pro
8 core xeon with 12GBRAM
It's running a 64 Bit capable processor
But the EFI is stuck at 32
Tried using the 32-64 bit kernel start-up selector program but it crashes when switching to 64 bit start-up !
Any help would be appreciated !!!

I'm having the same problem. Opens fine on my MBPro but not on my Mac Pro tower. The strange thing is that LR2 is running in 64 bit mode on my MBPro, but, the "open in 32 bit mode" box is still checked. Flat-out will not open in 64 bit mode on my tower. I checked with tech support, but, they could only get it to open on my tower if I created a separate user log-in on my tower and then it would open in 64 bit mode under that "new" user. So, they reasoned it was a "user configuration" issue.

Mac Pro Early 2008 will not boot off Win7 Install DVD

Hello,
I am hoping someone out there will have encountered something similar and have some suggestions or ideas, because at this point I can't think of anything else to try.
I have a 2.8 Ghz 8-core Mac Pro (Early 2008) with an Nvidia 8800GT Graphics card. I am running OS 10.6.2, fully patched and updated.
I am attempting to install Windows 7 Ultimate via Boot Camp, and am encountering a rather odd problem.
Once I have launched Boot Camp Assistant it allows me to partition the drive and does so correctly, but when it attempts to reboot off the Windows 7 installation DVD, I encounter a blank grey-white screen similar to that which you normally get on startup but without the Apple logo. This continues for some time (it seems to vary), and then the screen goes dark and the monitor says it is receiving no signal. The fans on the Mac Pro go for a while, then it goes to sleep. I've tried leaving it for a couple hours, no dice.
I've tried both the 32-bit and 64-bit Windows install disks. I had the release candidate for Windows 7 installed previously, and it worked perfectly. I have since tried that same install DVD that I used to install the release candidate, and it encounters the exact same issue. Booting up off the Snow Leopard Install DVD works fine.
I tried doing a clean install of Snow Leopard on a spare drive, booting off that, and then starting from square 1 using Boot Camp Assistant to re-partition that same drive. Same problem. No matter what I do or try, my Mac Pro does not want to boot off this install disc. I have yet to try the disc in another machine to see if it works there, and I will as soon as I can, but the fact that the RC disc worked a few months back and now will not seems to rule out the boot discs as defective. I've also tried both my internal optical drives with no change, and no other discs have any issues.
I've already spent an hour and a half talking to Apple Technical Support, and they seemed stumped, so I'm hoping someone will have a notion. If not, I understand and appreciate you taking the time to read this- I have no idea at this point, and I'm generally a pretty knowledgeable user.

Thank you for your reply,
Pull all the drives you have other than the one that you will install Windows 7 to.
I think I will try this next.
Don't put Windows 7 on the same drive as OS X, give it its own.
That was initially what I started out doing.
And you don't even need Boot Camp Assistant.
True, but it's what Apple suggests using.
Might also want to try moving the monitor cable to the other card port.
Hmm, I think I'll try that.
Any other PCI cards or devices attached or installed should also be questioned or disconnected.
I've disconnected everything I could.
Always a good idea to start fresh which I assume you are doing (not trying to upgrade over RC etc).
Yes, the drive was empty to start with.
Honestly it seems like the Mac Pro is generally refusing to boot from any Windows disc. Things I've tried since my initial post:
- Loaded Windows 7 Install disc into my room mate's windows PC... loaded up fine, got to install screen
- Tried his OEM copy of Windows Vista 32-bit, same issue
At this point it seems like maybe some kind of firmware issue or some kind or graphics driver issue, but I'm pretty much grasping at straws at this point. It doesn't seem like it's even getting to the point where hard drives or anything matters.
It does recognize that I have a Windows 7 install disc inserted when I use the boot selector/startup disk chooser.
Thanks for the ideas, I'll try those out and see if any of them help,

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..."

MacBook Pro 15" 2.5 not booting up

A friend has a 2.5 GHZ 15" MacBook Pro and it's not booting, it appears the Apple logo and then the spinning wheel.
What can I tell him to do since he's not in the same city I live and that machine doesn't come with a dvd installer.
Thanks in advance

IF this is the only point of comparison (2.5GHz vs 2.8GHz on the current 15" MBP) you will probably never notice a difference between the two ... unless you are into hardcore video editing, Photoshop or gaming. Even then, a) you will be hard pressed to notice a difference without instruments to measure it and b) there are many other factors that can affect system performance way more than this trivial difference in CPU speed on a top-of-the-line Mac laptop.
If you have the $200 it would take to upgrade to the 2.8GHz CPU, I suggest a better investment would be to apply the money to upgrading to the 1TB Flash Storage or use it to get a good external hard drive to use for backup.

Mac Pro 3.1 won't boot

A couple of weeks ago i turned on my mac pro and it didn't boot!
The video card fan whirls around for about 5 seconds and clicks off.
After looking around this forum and others for a while i thought it might be a power supply issue. So i took the tower to my local Apple repairer to get fixed. I called a week later to find out what the deal was and was told that its not the power supply and they were still looking at it. A few days later i got a message saying that it had bad ram and was fixed. leaving me 2gig of ram down (i had 8 gig of ram leaving me with 6 gig) and $75 out of pocket.
No sweat!
About a week later it did it again! Not booting!
i push the power button a few times and it booted! Phew!
It did this for a couple more weeks. Not booting sometimes. A few pushes of the power button and away we go.
Until of course i had a recording session booked and the mac pro would not turn on at all!
I've taken all the ram out (8 1gig sticks) and just installed 2 gig at a time. Going through all of them. Even the one the repairers said was bad. With no luck. I've reset the SMC and take the battery out and put a multi meter over it and it seems fine. (I must say that one day the screen went all weird. Kind of like blurred checkers for a minute but came good again.) I tried to boot it up without the graphics card, no luck!
I'm not sure what i should do??
Take it back to the repairer for another $75 or buy some more ram and see what happens.
Is it possible that ALL the ram is stuffed?
Is it possible to boot up without the video card?
Any advice you guys could give me would be greatly appreciated.
Thanks heaps
Damien

High quality while inexpensive work perfectly. 4% hit (but then use 8 DIMMs and you get 17% boost too).

I cannot get my Mac Pro (Original) MacPro1,1 to boot with the 64 Bit kernel in 10.6.8

I cannot get my Mac Pro (Original) MacPro1,1 to boot with the 64 Bit kernel in 10.6.8 (this is a 2 x 3Dual-Core Intel Xeon machine).
Firmware = MP11.005C.B08 (EFI 1.2) 1.7f10 (SMC 1.1)
Will it not run the 64 bit kernel?
Is there a firmware upgrade to allow this?
Should I bother?
It won't boot with the Key 6 & 4 method.
or using Terminal command;
sudo systemsetup -setkernelbootarchitecture x86_64
Any suggestions?
Thanks in advance...
Eric

Because it can't and doesn't have a 64-bit supported firmware.
UEFI (EFI64) was not finalized and adopted until very late 2007 and introduced in 2008, by Apple, Intel, other members of EFI Group and Unified EFI. The Mac Pro Mid-2010 was the first time though that 64-bit mode was the default.
Does it matter? not really. you can't install 48GB RAM anyway, while there are some improvements from 64-bit kernal.
Also can't boot Windows 7 64-bit DVD to install properly. But you can run Windows 64-bit kernel because you have a 64-bit Xeon.

My 2008 Mac Pro running Lion will not play HDV1080i60 footage in FCP 7. When I open the sequence settings, all HDV codecs are hdv1, hdv2, hdv3, and so forth. Anyone have any idea how to fix this?

My 2006 - 2008 Mac Pro running Lion will not play HDV 1080i60 footage in FCP 7. When I open the sequence settings, all HDV codecs are hdv1, hdv2, hdv3, and so forth. However, when I open the project on my other Mac Pro running Snow Leopard and FCP 6, the footage works fine as it does on my newer Imac running Mavericks and FCP 7. I have tried a Quicktime update on the Mac Pro that the footage doesn't work on but it says that I already have the newest version of Quicktime installed. I have also tried reinstalling the Final Cut Pro Studio twice, still no fix. I'm completely out of solutions and need to be able to edit HDV footage on this machine. Any help would be great. Thanks.

there was a recent software update that seemed to screw HDV up. Do some searching here over the last month or 2 and you'll find a bunch of posts and some possible solutions.
Worst case scenario, do as Shane suggests. But might I suggest you take a look at the user tips section of the forum. there are some great tips on how to prevent these sorts of problems by cloning your startup drive, etc.

Using the New Mac Pro (can) - AE will not let me use Race Traced 3-D

Using the New Mac Pro (can) - AE will not let me use Race Traced 3-D
Hi, I'm using the new Mac Pro
2.7 GHz 12-core Intel Xeon E5
64 GB 1867 MHz DDR3
AMD FirePro D700 6144 MB
OSX 10.9.2
I'm using After Effects 12.2.1.5
When I attempt to invoke the race trace 3D renderer in a comp, I get this error
"After Effects Error: Ray-traced 3D: Out of paged mapped memory for ray tracer. Your project may exceed GPU limits. Try closing other applications. Try updating the CUDA driver. (5070::2)"
My preferences are set to use the CPU for Raytraced 3D since I do not have an Nvidia card.
So, obviously there is an issue here in that it thinks I have an Nvidia card.
I know (or assume I know) the cause for this is that when I set up this machine, I used Apple's migration assistant to move most of my data over from the previous gen Mac Pro which DID have a CUDA card.
So my question is, what files can I delete/reset to cause After Effects to no longer look for CUDA files that do not exist on this machine?
I do not have the CUDA control panel in System Prefs, so THAT did not carry over.
Any ideas would be appreciated, thanks!

> I know (or assume I know) the cause for this is that when I set up this machine, I used Apple's migration assistant to move most of my data over from the previous gen Mac Pro which DID have a CUDA card.
Ugh. That causes so many problems.
The first thing to try is deleting the CUDA frameworks from your Mac: Look in /Library/Frameworks for the CUDA.Framework and get rid of it.

I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard.

Good Morning,
I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard. I shut it off took out the battery, reinstalled the battery. Then I put in the Snow Leopard CD and booted up to disk utility and The Snow Leopard partion would not show up?? I do see the microsoft partion.
I also rebooted holding down the shift key and still no Snow Leopard
Could you please tell me what I can do, what keys do I press on restart any advice to get Snow leopard back.
thank you.

Have you restarted holding down the Opt key? That procedure should give you a gray screen with all of the partitions that exist. Then select the SL partition for boot. Also go to System Preferences and Startup Disk, unlock the lock and select the SL partition as the default boot partition, then relock.

My macbook pro running lion will not boot . it stays on the grey page with the cog spinning. I have tried all methods of booting to no avail. I have removed the bottom and taken out the battery and the ram . will this affect my applecare warranty.

My mac pro mail photo browser not opening

my mac pro mail photo browser not opening

I actually have it the other way thinking of my iDevices as windows into my mail and my MP as my main repository. I also set my devices to delete of server any mail I move from my devices inbox to minimize multiple deleting unwanted mail.
But the real issue was to be able to access all my stored mail on my MP when traveling. IMAP is a way to go, yes. But my concern, please educate me if I'm wrong, I have 6 email accounts. With POP I can drag any email from any account to the ame folder on my MP.
As I understand IMAP each account would have its own sets of folders. So where I have "Work" ot "ToDo" folder that hold all mail regardless of account, I couldn't have one folder "Work" and drag all mail to it because folders are created per account, per ISP (and I have multiple accounts from various ISPs).
So I'd have to have a Work folder for each IMAP account and have check each instead of one the way it's set using POP - ON MY MAC on my MP.
If I'm right abou this, then using a remote app like SplashTop 2 to use any device to login to my MP to read, reply, delete, store, then is a great solution since I'm actually working on my MP remotely. Only problem would be if I forgot to turn my MP on before traveling.
Am I on the right path?
