Will the new 2012 Mac pros boot on Snow Leopard (10.6.8, installed on a HD in a 2008 Mac pro and then moved to the 2012 model).

I keep getting fuzzy answers on this (firmware, future updates, etc.). I can make a 2 partition HD on my 2008 (3.1), with Snow Leopard 10.6.8 on 1, and Lion on the other, and then put this HD in the 2012 3.06ghz. Will it work? (It does on the 2010 2.93ghz).

Tony https://discussions.apple.com/thread/4051765?tstart=0 Never got back and until someone who received a "new" Mac Pro 5,1 (5,2? just for laughs?) to know.
Apple ties OS build and fiirmware and Mac ID.
It should after all nothing really changed. In this case it has the same latest firmware that shipped iwth some 2010s
We had discussions about this when Mac Pro 2010 started shipping with Lion last... summer/fall.
A true Lion only system ships not only without DVDs, and with Lion, but can do a network install (it grabs a small boot loader) to pull down the installer and has enough code in the firmware. Same with AHT.
A. It (10.6.8) works and you are fine
B. It works only with Lion.
What is the real question? do you need to run 10.6.8?
There is a 1/20 chance too that it has a later build of 10.7.4, right?

  • Late 2008 mbp - installed new ssd - trying to boot from snow leopard iso on flash drive - says 'cannot install mac os on this computer'

    Hello -
    I just installed a new M500 Crucial ssd in my late 2008 mbp - everything was working fine on old hard drive (running snow leopard) but was getting slow and wanted to upgrade - i lost my snow leopard disk when moving from hawaii so i found an iso online - using a flash drive i partitioned the disk and made the bootable image on flash drive - formatted as extended/journaled - switched out the hard drives - plugged in the flash drive - started the comp - held option - install begins to boot - choose language - all is fine - choose english - next step window pops up saying 'cannot install os on this computer' - click on utility but all options are greyed out - disk util is greyed out - only options it gives is to start from backup or restart - real confused here - all help appreciated - thanks in advance and happy new year!

    Snow Leopard comes in discs only.  The USB drive may be a counterfeit and/or corrupt.  There are two options for you: 
    Get replacement original OSX installation disks from Apple customer service.  Have your MBP serial number ready and there is a charge.
    Or two, purchase a Snow Leopard disk from the Apple online store:

  • 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.

  • 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.

  • What is the difference between the new 13" MacBook Pros and the previous version of the 13" MacBook Pro?

    What is the difference between the new 13" MacBook Pros and the previous version of the 13" MacBook Pro?

    Note that iStatPro has not been updated in quite awhile and may not be reading the guts of a totally new system correctly. IIRC, the Late 2011 MBPs were beginning to tax iStatPro already, as they had newer sensors the older code was completely unaware of.
    For strictly measuring temps on the guts of these newer Macs, maybe use Marcel Bresink's free Temperature Monitor? Last updated in March 2012. In my Late 2011 15" MBP, it picks up all 18 sensors...

    Or go whole hog for his Hardware Monitor, for oodles more info from the Mac. Follow the Products link from above.

  • I got a new laptop (Macbook Pro) and my IPhone is synced with my previous laptop. I've recorded dozens of very long (un-emailable) Voice Memos over the last few weeks and need to get them from my IPhone onto my new laptop. How do I do this?

    I got a new laptop (Macbook Pro) and my IPhone is synced with my previous laptop (which I no longer have). I've recorded dozens of very long (un-emailable) Voice Memos over the last few weeks and need to get them from my IPhone onto my new laptop.
    How do I do this?
    (when I click on the Sync option I get the warning: "Are you sure you want to sync music? All existing songs and playlists on the iPhone will be replaced with songs and playlists from your iTunes library." I fear that if I click this I will lose all of my important Voice Memos as well)

    Just to add to what ChrisJ4203 said.  You can sync them to your new computer using iTunes by selecting to Include Voice Memos on the Music tab of your iTunes sync settings and syncing.  However, you still need to re-establish syncing with the new computer without iTunes erasing all the iTunes media from your phone (as the warning mentioned).
    If you copy your entire iTunes folder (not just your music) from your old computer to your new one, along with other non-iTunes media you may be syncing with iTunes (such as contacts, calendars and any photos synced to your phone from your old computer) by using migration assistant of following one of these methods: http://support.apple.com/kb/HT4527, then when you sync again with your new computer it will recognize your phone and sync as it did before.  You will still have to authorize the new computer for any Apple IDs used to purchase from the iTunes and App stores (in iTunes>Store>Authorize this computer). 
    After that you can sync your voice memos to your computer as mentioned earlier.
    If you want to archive your voice memos before you do anything with iTunes, you can use a 3rd party program such as PhoneView or Touch Copy.

  • I had a windows laptop, and I save files like photos, documents, videos and other things on an external hard drive, and now I want to move those files to the Mac book Pro, and then move those files again to another external hard drive 1T. My question is:

    I had a windows laptop, and I save files like photos,documents, videos and other things on an external hard drive, and now I want tomove those files to the Mac book Pro, and then move those files again toanother external hard drive 1T. My question is: Is it possible? Doing this willnot affect the files that I had in windows? No information is lost? or how cani do it?

    Connect the external drive to your Mac and drag the files from it to your Mac's internal drive. Then dismount and disconnect the external drive, connect the 1TB external drive, and drag the files from the internal drive onto the external. Nothing will have been deleted from any of the drives up to this point; the files will only have been copied. Verify that the files are readable. There's no reason they shouldn't be; this is just a precaution.
    Now if you wish to delete the files from any of the drives, drag them to the Trash, and Empty the Trash while the drive from which they came is still connected. If you disconnect the drive before emptying the Trash, the files you were trying to remove from it won't be deleted. They'll remain in the Trash and continue to take up space on the drive.
    Note that if your external drives are in NTFS format, you won't be able to write anything to them or delete anything from them, though you will be able to read and copy the files they contain. The NTFS disk format is read-only to the Mac OS, unless you have a third-party NTFS driver installed. To make your drives cross-platform readable and writable, you must reformat them in the FAT32 or ExFAT format.

  • HT1343 On my 4 1/2 year old Macbook I could select multiple files  by highlighting a file and then moving cursor over a file lower in the list, and pressing shift-control-click. I can't do that in now with Mac Pro.  What am I doing wrong?

    ghlighting a file and then moving cursor over a file lower in the list, and pressing shift-control-click. I can't do that in now with Mac Pro.  What am I doing wrong?

    Holding down the control key will invoke "right-click."
    Depending on the View, holding down Shift will with either toggle the selection (Icon View), or it will make a continuous selection from the previous selection (List View or Column View).
    The only way to make a continuous selection in Icon View is to drag out a selection marquee around or through the icons.
    I can't remember the behavior of previous OS's.

    I'm sorry, I should have said thru Bluetooth, not Wi-Fi.  I want to use the mini as a base station and the iPad like a laptop that I can sync when I'm home and carry with me when I travel.  Is is possible to hook these 2 up - iPad/mini, through Bluetooth?  I understand I need to use a regular monitor/keyboard/mouse on the initial install.

  • I'm new to Mac's and I find the display's just slightly too small. I'd like to increase the size for all my program. Is there a single setting that I can change?

    I'm new to Mac's and I find the display's just slightly too small. I'd like to increase the size of my display for all my programs. Is there a single setting that I can change as a default setting?

    You can drop the resolution a little, but it makes everything blurry.
    OS X isn't as friendly like Windows is to give some UI adjustment, one of many major complaints about the platform that has gone unheeded for years now.
    As a lifelong Mac user who's eyes are going due to age, I'm really liking Windows 7 more and more every day.
    If you use Firefox, NoSquint and Theme Font & Size Changer add-ons, with a nice persona that makes better contrast, tweak the FF toolbars, you can at least make your web surfing tolerable on Mac's.
    Also you can set a Control key in System Preferences > Universal Access plus a scroll wheel mouse, if you need to zoom in/out certain areas of OS X, however for a pernament UI scale solution there is none that's practical, unless you have a large room, a projector and a smooth wall.
    A larger monitor won't work up close neither, however dropping the resolution and sitting back a bit might sharpen the images a bit.
    The UI really needs to be adjustable and it's not.

    What is the difference between the new 13" MacBook Pros and the previous version of the 13" MacBook Pro?  I purchased an "old" one from Best Buy the day before the announcement of the new models.

    See the specs:

    Compare with your model. If you are within 14 days of purchase you can exchange for the new model for the difference in price, if any. Be sure to have all the original packaging and your receipt.

  • I am new to mac's and have upgrade from Snow Leopard to Lion but......

    I am new to mac's and have upgrade from Snow Leopard to Lion but not all my application will work. Is it save to reinstall using original snow leopard dvd and does it wipe all my other application like apature? I am in a panic over this, any help!!
    I came across this online and i want to know is it safe to do this:
    Backup your User folders to an external drive. This should preserve your documents, photos, music, etc. If you store those things in locations not in the User folder, make sure to copy those over too.
    Insert the Snow Leopard disc. Restart your Mac and hold down C to boot to your DVD drive.
    Go to Utilities in the menu bar once the installer pops up and select “Disk Utility.”
    Find the drive in the sidebar where Lion is installed, select it and navigate to the Partition tab.
    Click on the drop down menu under Partition Layout and select “1 Partition.” Hit Apply.
    Now navigate to the Erase tab and make sure “Mac OS Extended (Journaled)” is selected, then hit Erase to delete all data on the drive.
    Quit Disk Utility to get back to the Snow Leopard installer and proceed with the install.
    Restore your User folder and documents from your backup.
    Run Software Update to get everything current, install your apps from your original install media and update those as well.
    if any one can help me that would be great, thanks Mike

    Before you do that why not do this first:
    Repair the Hard Drive and Permissions
    Boot from your Lion Recovery HD. 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.
    To boot from the Recovery HD restart the computer. After the chime hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    If this doesn't help, then you can proceed to reinstall Snow Leopard as follows:
    Downgrade Lion to Snow Leopard
    1.  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.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Quit DU and return to the installer. Install Snow Leopard.
    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
    This will erase the drive so be sure to backup your files before doing this.
