HT1444 mac pro will not successfully load snow leopard

mac pro will not successfully load snow leopard 10.6 ? presently using 10.5

Haha! That's true. Though I've noted many users here calling a Power Mac a Mac Pro and visa versa.
When my Power Mac died and I brought it into the Apple Store to have them look at it, the first Mac Pros hadn't been out that long. Even the staff didn't know the tower Mac they had out on display was a Mac Pro. I pointed out that it had two optical drive bays in front. Only the Mac Pros have two. All Power Macs have only one.

Mac Pro will not boot with Snow Leopard - need help!

I have had a lot of issues with Snow Leopard since I upgraded from 10.5.8. Most of my problems started after installing Office 2007. I finally wiped the hard drive and reinstalled everything. No problems until last week. Start up was taking longer and had to reboot a couple of times because of grey screen. So I would just put computer to sleep. Yesterday the computer was frozen on screen saver with scrambled rows of pixels on screen two and the main monitor had a frozen image.
I initially pulled all peripherals out and pulled the power plug for 5 minutes. I have left the peripherals out and pulled the second monitor as well. I tried pulling the power plug during a few more starts but nothing gets me to a complete start up screen.
I have tried resetting PRAM and VRAM and tried a safe boot. I tried booting from Snow Leopard and my Leopard disk stayed on either a blue or gray screen with spinning beach ball (on gray screen).
Put original install disk in and booted from using D to check the hardware. Good news is that the hardware test was OK. I did the extended test.
All different kind of start up problems.
- Some start with start up sound goes to Apple logo to blue screen to grey screen with beachball
- Some start ups with no initial sound then Apple logo to blue screen to grey screen with no cursor or beachball
- Some start ups with no sound to gray screen to blue screen to grey screen.
I have no problem wiping the HD1 again but I can't even get the OS disk to be recognized with holding the C key during start up. This last time it went to a blue screen (holding the C key) and a cursor.
I don't know what else to do - Please help!!!

There are lists (MacIntouch and MacFixit) of hardware / software support issues with 10.6. Accelerateyourmac is another place to watch.
There were some really long threads back in Sept about printer driver support.
The 7300 firmware was more about Windows support; those cards are failing and dropping like flies (how DO they know 3 yrs has expired anyway?) and they don't support SL features like OpenCL etc so I'd invest in ATI 4870, best graphic card and works in all models Mac Pro.
Lots and lots of bootable clones for backup. Never need to wipe and install again.

Macbook pro will not boot after snow leopard upgrade

My GF has had a macbook pro since mid 2008. It's been running like a champ since I've known her for the past 3 years with no issues. It has/had OSX 10.5.8 installed. We tried to consolidate all our pictures from all our apple devices and realized she didn't have an icloud on the old 10.5.8 OSX. So I called apple and they told me to order and install the snow leopard OSX 10.6 first and then upgrade to lion etc after that, Well we got the disk yesterday popped it in to install and it's been a disaster.... the computer shutdown for what looked like a normal restart during the installation process and never booted back up. Attempts to manually reboot leave us locked on a grey apple logo screen with spinning gear indefinately whith the Snow Leopard disk installed during boot up. With the disk removed I get the flashing file folder with a question mark. I called apple support we tried all the PRAM and SMC resets and then decided that we should go to the Genius Bar once all those failed. After an hour and a half drive to the nearest genius bar we were told that the we suddenly had a hardware issue which just happened to coincide with the new OS installation.... I'm not buying it and am looking for some help. The macbook was running like a champ until we inserted a disk recommended by apple... Any takers?

You have a five year old computer, so a failing hard drive at this point is not so strange. You have a couple of options you can try. Start with this one, but if it does not work you will have to erase the hard drive. I hope you have a backup of all your files.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Mac pro will not restart.

When I try to update software my mac pro will not restart. So the software does not update. What to do? I have tried unpluging all external drives. No luck. The screen just stays in the infinity picture. I have tried waiting 5 minutes. Still no restart.

You are still using 10.6.8, just to confirm, so you don't have Recovery Mode for one thing. But do you have a backup that is bootable? make one now before you do more. And try repairing the drive as well as doing a Safe Boot.
You may need to do a clean install to another drive. Apparently you have another Mac or something to post and get online so you could also use Target Disk Mode to access the system in trouble.
Update with what from what? what other internal drives are there?

2009 Mac Pro will not boot up under Windows

I have an Early 2009 Mac Pro system (Mac Pro 4,1) and I've had this system for 3 years already and have been working under OS X with this system ever since I purchased it.
However, when I tried to boot off my Windows disk, something very interesting happens. The Mac Pro WILL NOT boot up off the Windows disk or a known working Windows partition if two monitors are connected. Upon holding down the option key and selecting the Windows partition, I will get a black screen on one monitor (the one connected via Mini Displayport) and the other screen receives no signal and will enter standby and the system is halted. It does not respond to keystrokes, there is no hard drive activity, no measured power increase on the UPS, no apparent network activity, nothing. The only way to exit this scenario (from what I can tell) is to power off the machine, disconnect the display on DVI, power on the machine again, select the Windows partition wait for the system to reach the login window and reconnect the DVI monitor (at which time Windows recognizes it immediately and the system works fine again).
My question to the community is, does anybody know why this is happening and is there a known fix for this? Quite frankly, having to disconnect a monitor just to restart is very tedious and frustrating.
I have two Samsung P2350 monitors attached to an ATI Radeon HD 4870 (512MB, from Apple). One is monitor is connected via directly DVI and the other is using a Mini Displayport to DVI adapter. Both monitors work fine under OS X with no issue. At first, I thought that this may be a driver issue on the Windows side and after installing all the latest updates and drivers the issue is still apparent. From what I can tell, this doesn't seem like a software issue but rather a firmware or EFI issue as this happens before Windows even loads.
If anyone knows of a fix or what to do in this situation, or if you are also having this issue, I would love to hear your input!
Thank you!
For the record, I am running all the latest software builds on the OS X side (10.7.4, not that it would really matter at this point). I have also disconnected all unnecessary equipment in a trial and error scenario but the results are still the same.
The system passes all ASD testing.
The full specification of the computer and all connected equipment are as follows:
2009 Mac Pro (4,1) 8-Core
2x Intel Xeon Nehalem 2.66GHz Quad-Core CPUs
16GB DDR3 ECC 1066MHz RAM (Apple Branded)
Two OWC 120GB SSDs (One for OS X, the other for Windows 7 x64) - These are in place of my optical drives.
4x 2TB WD Black Hard drives for storage.
Two Samsung P2350 Monitors connected via DVI. (One using a Mini Displayport to DVI adapter).

In Windows I am using the latest (12.4) Catalyst Software Suite, 64 bit of course, downloaded directly from AMD's site after installing the drivers from Boot Camp.
As for installing Windows I used an original (not burned) installation media (Disk is in a pristine condition). And yes, Windows is fine, the problem just seems to be getting the system to boot up Windows with that second monitor. However if the "problem monitor" is disconnected the system boots fine 100% of the time and connecting it later after booting the system will still operate properly.
For the sake of arguement I swapped monitor cables and connected the "second" monitor to the mini displayport adapter to verify that it wasn't a cabling issue and I'm still yielding the same issues.
As for GPU testing, I've played games (Crysis, Grand Theft Auto IV, Battlefield 3, etc.) and I've had no issues with the card or stability.
You would think that Apple would try to find a fix for this, especially considering the caliber of this machine.

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What happened?what do I do now??????? Help!

Note that you don't have a Mac Pro as stated. Your profile says you have a MacBook Pro. Please clarify as they are entirely different computers. If nothing below works for you, then make a Genius Appointment and take it in for service.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

We've used the 400 to 800 firewire cables with limited success in the past...dropped frames was the main problem. Only used them until the Sonnet FireWire PCIe Card came in to allow a 400 firewire.

Mac Pro will not shut down

As the subject line says, my "early 2008" Mac Pro will not shut down. I have let it set overnight and it will not shut down or restart. I also installed an update which required a restart, selected to restart and the computer would not. Also, whenever I boot up, the computer hangs and will not load the finder. I have to do a "hard" restart and after a couple tries it eventually works...should I just call Apple?

Forced shutdowns tend to cause more directory errors.
How many drives?
Any green version?
Did you disable "allow disks to spindown"?
Possible it is an external USB printer or device, or cable?
I'd boot from another hard drive and do system repair and maintenance.
Create another boot volume if need be.
Startup with using Disk utility but also Disk Warrior.
And when it is working, make backups with CCC or SuperDuper.
Lacking that, boot from OS X DVD and go to Utility menu and access Disk Utility.

For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

Apps store icon no longer available, book shelf will no longer access the store, and my mac pro will not sinc apps with my iPad. What's up?? How do I correct? This is after upgrading to iOS6 and Mountain Lion.

Saw this on another post.
Applecare Senior Advisor Txx Bxxx (I have his contact info in an email he just sent) just confirmed with me that the problem people are having with the App Store not loading is an apple issue with there servers, ITS NOT YOUR IPAD so don't go restoring it! It's not happening to everyone however but they are looking into it, its really hit or miss.

Try this first - Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
This works for some users. Not sure why.
Go to Settings>General>Date and Time> Set Automatically>Off. Set the date ahead by about a year.Then see if you can connect to the store.

Mac Pro will not find boot volume

Hello,
My Mac Pro will not find it's boot volume. Each time the computer is started, the blinking folder with the question mark is the result. A working install of 10.7 does exist on the machine's primary hard drive. If I were to press the option key on boot, I can select the primary hard drive (after entering the password) and everything boots as normal. I have run TechToolPro on the volume with no detected errors, even after a volume rebuild. A Recovery HD partition is not on the boot volume. Should that matter?
I really really do not want to reinstall Mac OS X. I have hundreds of gigabytes of data in question. Any reinstall/reconfig would take days to complete.
Thanks

So you are saying that setting the default in Startup Disk doesn't work?
And you have not got or been using Carbon Copy Cloner or another to provide working bootable backup?
You should have Lion Recovery on one of your drives, do a clean install.,
I assume TTPro media scan turns up no errors.
MOVE all your data OFF the boot drive. Keep the system OS and apps on its own drive.
Clone the system. Use TimeMachine and cloning for backup.
And how is the pram battery?
Any time you zap pram you lose the default and it will look for it like you see starting with SATA0 (bay 1)

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.

HT201364 My Mac Pro will not upgrade past 10.7.5 Now what?

My Mac Pro will not upgrade past 10.7.5 Now what?

No, it is not possible. I have an early model, too, that now sits in a corner. I replaced it at the time with a mid-2011 iMac. The only less expensive route than a new computer is a used/refurbished model, but were you to go that route stick to a 2009 or later model MP.
Surely your business can afford £2500 for a necessary asset. It's depreciable for tax purposes if your tax system allows that. Just ask yourself how much it would cost your business if you did not have a computer. And, consider, if you really need to get a new computer assuming the one you have is still working. Keep it and start putting away enough from your business revenue to buy a new computer later. It's a required part of business planning.

Mac Pro will not restart from dropdown menu

Hi all,
My Mac Pro will not restart from the dropdown menu or when clicking the 'restart computer' when installing software updates. I have an external firewire hard drive hooked up as part of my backup process. It contains a clone of my startup disk.
I have tried disconnecting the firewire drive, rebooting then attempting to restart from the dropdown menu. Still no joy. I always have to end up shutting down manually by holding the power button in and then restarting with the power button.
Any thoughts?
Thanks in advance.
Dennis

You might try Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)
If your Shutdown functions correctly that way, go to System Preferences >> Accounts >> Login Items, and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting.
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
EDIT: Also, if you can launch Activity Monitor in your Utilities folder and see if you can find the process that is still running.
