MacPro 3.1 will not upgrade to Snow Leopard

Hi. I have a MacPro 3.1 with 2 x 3.2 GHz Quad Core Intel Xenon Processors, 6 GB of Ram. The computer is a standard Apple Unit.
I cannot get it to install Snow Leopard. Info elsewhere on this site suggests it should run under Snow Leopard. I have put the system back to Factory state with a clean install of 10.5. It still will not accept the Snow Leopard.
I suspect the problem may be me trying to use installer disks recently supplied with my new MacBook Pro 13", 2.53 GHz. Can anyone confirm this issue. If I buy another copy of Snow Leopard, that is not apparently Machine specific, will it install?

Yes, the disks are your problem. All you need to erase and install Snow on you MP is the $29.00 Snow upgrade disk. You do not need to ever had have Leopard installed.

OS will not boot after Snow Leopard Upgrade

I have a MacPro (Intel). I just upgraded to Snow Leopard and everything appeared fine. However, after restarting my computer the OS will not load. A circle with a hash through it replaces the Apple logo and the apple's spinning wheel continues but all drive activity. I have tried to run the install again by forcing the computer to open the dvd drive then booting for the OS DVD but this has not worked. Has anyone experienced this and successfully resolved?

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.

My iMac will not boot through Snow Leopard but will boot through Windows OS

My 2010 iMac will not boot in Snow Leopard, only Windows. Have tried reinstalling Snow leopard a few times and works only for a couple of minutes before freezing and doesnt reboot. Windows works perfect. Snow leopard just doesnt want to boot up past the Apple Logo. It was working fine one day and the next day it froze up and was able to reboot back into Snow Leopard but kept freezing. Now it doesnt load at all into Mac OS.

Possible scenarios:
1: The 10.6.3 SL retail disk is bad, it happens.
2: Your not using the 10.6.3 SL retail disk but one from another machine which doesn't have the drivers for that machine.
3: Your optical drive is funky or some other hardware issues.
4: Your trying to install 10.6 onto a PowerPC based Mac, no can do.
5: Your not using a wired keyboard for boot key commands, have some other hardware conflicts.
Possible solutions.
1: Copy the SL 10.6.3 disk using Disk Utility to another DVD, the error checking may resolve the original disk's issue.
http://www.brokenhomeboy.co.uk/pierow/blog/2011/10/make-a-bootable-backup-snow-l eopard-install-disc/
2: Make a SL bootable USB
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
3: Call Apple for a new 10.6.3 disk (and make copies for backup before Apple discontinues selling it)
If your upgrading to 10.6 to get to 10.6.8 to upgrade to 10.7, be warned of this:
1: Your 10.5 software will not work in 10.7, no more Rosetta or PPC based code.
2: Your hardware will not qualify if it's a 32 bit Intel Core Duo, also you may experience slowdowns in performance over 10.6 (10.6 is the fastest OS X version for Intel Macs) in older Intel hardware (I suggest Early 2011 Mac's and later only for Lion)
3: Mountain Lion 10.8 is reportingly coming out this summer and will not run on a lot of older Intel based Mac's because of heftier graphics requirements.
4: 10.6 has the widest range of current avaialble software and drivers for third party hardware.
My advice, stick with 10.6.8 and stay there, buy a new Mountain Lion machine after this summer. Skip Lion completely.

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.

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.

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?

AE CS4 Will not open after Snow Leopard Upgrade

Ok, i posted this earlier but I don't think I was clear enough to get an answer. I recently did a clean install of Snow Leopard and a fresh install of my Production Studio CS4. Upon getting it all installed, I realized that After Effects will NOT open at all. It just bounces on the Dock a few times and then stops. Then after that, when you click on it, it bounces once, then stops. Every other program works great, only after effects is not working. Why is this? Is there something I need to do? I reeinstalled just the AE and downloaded the newest update, still, the same thing. I would appreciate any suggestions to get it running.

I experienced this when upgrading to Snow Leopard myself.
After Effects is one of many, many applications which require Rosetta to be installed. In Snow Leopard, Rosetta is an optional install on the disk. So just make sure you install it.
Now, the thing also is that once Rosetta is installed, the OS still seems to have AE flagged as an app which requires a missing component to launch. This was fixed after a couple of restarts, in my case.

Automator (version 2.04) will not run in snow leopard. Upgrade how?

Hi all -
I upgraded to Snow Leopard and find it wonderful. The only trouble I have is using Automator. The version I have is 2.04 and when I launch it, it gives me the following message:
"You can't run this version of the application Automator with this version of Mac OS X. You have Automator 2.0.4." My visits to Apple download site has been unsuccessful.
I did download an "Automator Extension Pack" from the Apple site for Leopard and that runs but it does not give me the function I need.
I want to stop and start an application on a schedule. Should be a simple task. Maybe someone can help me with that problem instead? I assume Automator is part of the solution.
Thanks for your attention. I am running 10.6.2 OS X.

The new version of Automator (2.1) should have been installed with the Snow Leopard update. It's normal location is in the /Applications folder, so if you had moved the earlier version to some other location or installed onto a different partition, make sure you are running the right copy.

GCC Elite XL 40 - Will Not Print in Snow Leopard

I am desperate I have wasted two days working with GCC tech support via phone and email and have followed their instructions for setting up my GCC Elite XL 40 as an IP printer for our MacPro running Mac OS 10.6.5. I have checked and double and triple checked the many settings on both the printer and my MacPro - ALL are correct (according to the instructions provided) but the printer will not Print. It is recognized by the computer — got a green light on my print queue — says its ready to print but nothing happens.
I have redone this so many times I - added, deleted and re-added the printer several times - I am just on the verge of giving up but I need this large format laser printer to work with this computer — it's our workhorse for big projects.
There was a Posting here from someone named Rocky dated a few months ago and that information conformed to what I have been instructed to do by GCC but it still does not work. All other Macs on our network are printing to the GCC Elite XL 40 just fine as usual. This is the only workstation we upgraded to Snow Leopard plus this computer is hard wired via Ethernet not Airport.
If there is anyone out there that has made this work please send me some info or direct me to an expert. Thank you.

Looking at the specifications for this printer it shows that the unit support Postscript Level 2, which indicates it's quite an old model. This could be causing problems with Snow Leopard.
The specs also show the printer supports PCL5e and PCL6. So did the GCC techs get you to try creating a printer queue using the Generic PCL Laser Printer? If not it would be worth a try. Make a new print queue using IP > LPD for the protocol, not sure if you need a queue name so leave this blank, and select Generic PCL Laser in the Print Using menu. This Generic driver gives you no options and probably no support for the larger paper sizes but it will let you see if you can get a print job from your Mac to the printer.

HP Laserjet 4100 will not print in Snow Leopard

Since I’ve installed Snow Leopard, I have not been able to print with my HP Laserjet 4100.
My set-up: new 24” iMac, many hard drives and more. Two devices: HP Color Laserjet 5550 and HP Officejet J5750 are connected to the iMac through a USB Hub. Although initially scanning did not work with the J5750, I was able to make that work once additional drivers were downloaded from HP. Both work fine.
I also have an older HP Laserjet 4100 which has been my steady workhorse for years. It only has Ethernet and serial port outlets. It is connected to an AT&T 2-Wired Ethernet Hub/DSL Modem (model 2701HG-B) that is connected to the iMac.
I’ve contacted HP and Apple about this problem. None of the three people I worked with at Apple could help and the HP representative was unsure if they could help but that it would cost me $40 to find out. According to HP website, since Apple Talk no longer exists, we are required to input the IP for the device. For the 4100, the IP address is 10.0.1.100. I tried this two ways: in the “Add Printer” window under “IP,” inputted as the IPP, and inputted as the HP Jetdirect Socket (as per the HP instructions). When this is done, the printer shows up when you give a print command. However, it does not show up in the “Add Printer” window under “default” or anywhere else.
Status: If I connect the 4100 Ethernet cable directly to the back of the iMac, the “Supply” level indicates the true level of toner in the 4100. However, it will not print. If I connect the 4100 Ethernet cable to the Ethernet hub, the supply level does not show nor can I print.
Any suggestions?

< Edited by Host >

Well, another week has gone by without a solution.
Again, here is the problem:
I have a 24" iMac connected to a USB hub and an AT&T 2-Wire DSL/ethernet hub. When I upgraded to Snow Leopard 10.6.1 and now the update 10.6.2, the two printers on the USB hub work fine but the HP Laserjet 4100dtn does not print. This old printer has only ethernet or serial ports. I've downloaded and installed the HP driver updates from Apple and HP to no avail. According to HP, I must add the 4100 manually using its IP. I've followed the instructions while adding a printer to select IP- HP Jetdirect - Socket. The address of the printer is 10.0.1.100. When I type this in, the window says that this is a valid and complete address. It searches and then says the "Print Using:" is a Generic PostScript Printer. The driver for this printer, I believe, should be "HP LaserJet 4100 Series v.3010.107" Regardless, when I click Add the window "Determining Installable Options" shows "Status: Connecting to printer..." It never establishes a connection.
The 2-Wire DSL/Ethernet Hub/Modem, has an IP of 192.1687.1.66, Submask 255.255.255.0 and Router (DNS) 192.168.1.254.
If I plug the ethernet cable directly from the printer to the iMac, the supply level shows correctly but will not print. If I plug the ethernet cable from the printer to the 2-Wire and then to the iMac, it neither shows supply level nor prints.
Any suggestion as to how to fix this problem? (I've been on the phone with 3 different Apple respresentatives and 1 HP representative with no success.)

Canon pixma IP4000R will not work with Snow Leopard

After upgrading to Snow Leopard, my Canon IP4000r printer will not work. I have tried both the Canon Printer Drivers 2.3 (my printer is listed) from Apple and the latest printer driver from Canon. There are multiple problems ... the first thing I noticed is that not all of the printer options are available on the print dialog. When I tried to print, I got "fatal::internal error -9660."
It looks like both drivers I've tried so far are CUPS (which is probably why all of the printer options are not supported).
Anyone have any ideas? Other than buying a new printer ...

After upgrading to Snow Leopard, my Canon IP4000r printer will not work. I have tried both the Canon Printer Drivers 2.3 (my printer is listed) from Apple and the latest printer driver from Canon.
The driver version provided by Canon is v10.26.x while the update provided by Apple will increase the version to 10.30.3.0. The v10.26 and v10.30 drivers provide all the features that the previous v4.8.3 driver for OS X 10.5 and earlier provided. However the layout for these menus is definitely different.
Also, a lot of user who upgrade from a previous OS X may not realise that the default print dialog is in a minimised view. You need to press the disclosure triangle next to the printer name to get the expanded view.
When I tried to print, I got "fatal::internal error -9660."
I suggest you try a printer reset.
1. Open System Preferences > Print & Fax
2. Move your mouse over the Printers list
3. Hold down the Control button and click the mouse
4. Click "Reset printing system ..."
5. Restart your Mac
This will remove your iP4000R print queue but not the printer drivers. So you will only need to add the queue again.
It looks like both drivers I've tried so far are CUPS (which is probably why all of the printer options are not supported).
Yes they are both CUPS by name as they are both made by Canon. But this is not your issue. If you believe that a particular option is not available then please reply with what that is.

Aperture will not work after snow leopard instalation,

Hi,
I have avoided upgrading to Snow Leopard but my children bought me the upgrade for Christmas as they want me to use Face Time. So I did, now aperture will not open and it says contact the originators of the program. I am a pro photographer and all my current work is on Aperture and I have a wedding in two days time and so this is somewhat disturbing as all my post production in done in Aperture. Can anyone help me I have done all the software upgrades etc.....

Are your images files managed in the Aperture Library, or Referenced? Do you have an external disk drive in the configuration, and if so, is it formatted as Mac OS Extended?
If you hold down the Option key while clicking on the Aperture Icon in the Dock, do you get the dialogue that allows choosing between different Aperture Libraries, or even creating a New Library?

Optical Bluetooth Mouse will not Pair in Snow Leopard 10.6.1 on MBP5,5

I have this mouse, with full batteries, just now tested and working on Windows XP with another laptop, and with an older MacBook Pro running 10.5. I can see this device in the Bluetooth set-up, and when I click Continue, the window shows a connection established, then another connection, and then an error that the device could not be paired. I tried every type of Password Options, including setting as 0000 and 1234. I have no other Bluetooth devices to test with either.
IOGEAR - GME225B - Bluetooth Optical Mini Mouse
I followed the instructions from other posts, but still cannot pair the mouse.
-Deleted Macintosh HD>library>preferences>com.apple.bluetooth.plist
-Reset PRAM with Command-Option-P-R keys at boot
-Installed Wireless Mouse Software Update 1.0 for Snow Leopard
Nothing works, but I know for sure that this mouse does work, and that it has worked on previous versions of OSX and other MacBooks.

I have the same issue. Same mouse. Its definitely snow leopard. I have 2 macbooks that use that mouse that were upgraded to snow leopard from leopard. On one of them I had deleted the mouse and encoutered the same errors trying to add it - it worked on my other machine. But then as a test (bad idea) I deleted it off the other machine and was also unable to recreate the connection thereby narrowing the issue to snow leopard. I have tried pretty much everything for hours. Deleting pllist file, smc reset, nvram etc... I think I have to wipe off the machine and install leopard again and start from there

MacPro 3.1 will not upgrade to Snow Leopard
