Boot from i7 installation on MacPro or CoreDuo MacBook(Pro)

I've built a new installation of Snow Leopard on my i7 MBP and installed many programs. From what I understand, I couldn't use an earlier SL disc because the i7 requires new drivers on the installation disc so I could only install with the disc that came with the MBP. I cloned the system using SuperDuper, restored it to an external drive and booted a CoreDuo MacBook and everything seems to be working fine.
The i7 MBP won't let me boot a CoreDuo installation off an external but it seems to work in reverse.
Does anyone see a problem doing this before I go any further?

Well, regardless of whether what you are doing may or may not work, you are violating the software licensing agreement which states that the Mac OS may only be installed on one computer - period. You may create a backup copy, but you cannot use that on another computer. And, so as to not violate the Terms of Use here, we are not allowed to help:

  • Boot from time machine to start up my macbook Pro?

    Can I boot up from my time machine to start up my macbook pro with 10.7.5? I have not been able to start up from my diskWarrior 4.4 disk in order to rebuild my hard drive, and I did not get a 10.7 system disk when I bought my computer. Also, if I can, how do I do it?

    If the time machine backup was made from your Mac with 10.7.x install on it yes toy can boot from it. Connect the backup drive to the Mac and power it on. Hold down the Option key and a boot menu screen willl come up. Select the backup drive, it might be label Recovery HD or Whatever you called the drive when you formatted it.
    Once that loads, which is a copy of the built ion Recovery HD files you can use disk utility to do maintance and do all the other things you can do with disk utility and then you can restore your system from that backup.

  • How do I boot from an external hard drive if my MacBook Pro only recognizes the internal drive?

    Hi there, I recently got the white screen of death (w/ circle slash) on my 13" 2009 MacBook Pro. Most people are saying that it is hard drive failure, so I am trying to boot it from an external hard drive to save some of my data before having it repaired. Unfortunately, every time I press "option" while it boots, it only shows the internal drive on the grey screen. I have my external drive connected, but it won't recognize it. What should I do?
    Thanks!

    Welcome to the Apple Support Communities
    You can only start from an external drive if OS X is installed there. If not, it won't appear as a bootable volume because there isn't any operating system inside it.
    As you have a Mid 2009 MacBook Pro, it's better to start from the Mac OS X disc that came with your Mac. Insert it and hold the C key while your Mac is starting. After starting, go to Utilities menu > Disk Utility, select "Macintosh HD" in the sidebar and repair it. If you can't get it repaired, take the computer to an Apple Store.
    If the hard drive can't be repaired, the only option to recover your files is to use an application as DiskWarrior, but it's expensive and it's not sure that it will work, because it may fail

  • Booting from external hard drive on intel-based MacBook Pro

    Good day everyone. I know similar questions were raised in this community, but I still have some questions.
    I have MacBook Pro(late 2011) with OS X 10.7.5 and external hard drive with Ubuntu 13.04, from wich i can boot succefully on my PC. But MacBook Pro will not boot from my external drive, no matter which key/combination i use during restart.
    After googling I found some answers to my initial question, how to boot from external hard drive

    As I understand I need to format my external hard drive into GUID partition type and this will be enough to be able to boot from it on my mac?
    With this new partition type, will I be able to install ubuntu again on my external drive?
    Does GUID partition type supports NTFS, ext4 and FAT32, linux swap?(I use ntfs for big files, ext4 as partition for ubuntu and fat32, because i use windows, linux and osx)
    Will I be able to boot from my pc from my external drive with this new partition type?
    What are downsides, if any, to GPT?
    here is info on my e-drive

    LowLuster wrote:
    The only OS that will boot from an external drive is Mac OS X or maybe Linux. For OS X to be installed on any drive it need to be formatted Mac OS Extended and have GUID partition table.
    As for Linux I'm not that familiar with it but again for a Mac to boot it need an EFI partition on the drive and I don't think that is possible with NTFS or FAT32 let alone the native Linux format.
    Went to wiki to learn more on efi but found artice on uefi.
    Operating system loaders are a class of the UEFI applications. As such, they are stored as files on a file system that can be accessed by the firmware, called EFI System partition (ESP). Supported file systems include FAT32, FAT16 and FAT12, and supported partition table scheme is GPT only. UEFI does not rely on a boot sector, although ESP provides space for it as part of the backwards compatibility.[26]
    Here is FAQ on official uefi website.
    Can UEFI Secure Boot be adopted and implemented by a variety of operating systems?
    UEFI specifications are platform-independent, supporting multiple platforms and architectures. In addition, UEFI specifications are designed to promote cross-functionality, as well as to support broad adoption across multiple operating systems, including Windows as well as Linux-based operating systems. The specifications are robust and can potentially complement—or even advance—other distributions, such as Linux-based distributions.
    And here is wiki article on GPT expaining OS support.
    It is obvious both uefi and GPT are ok with Linux and file systems such as FAT32, ext4 and NTFS.
    I guess there is no much difference(or is that the same thing?) between uefi and efi used in Macs.
    In your answer to Stark Industries you said that mac can boot linux from external hard drive, well this is not the info i got of official website and it is still my question, because your answer is very inconclusive and your info is partially incorrect

  • Can't restore from Disk Utility while booted from OS installation DVD

    I'm absolutely astounded by this.
    I have a new MacBook Pro 17". I restored my files to it and in short order, had it too full/fragmented to re-partition it for Boot Camp.
    So I decided to image the disk and store that image file on a FireWire drive, wipe the system disk and restore it cleanly from the image file backup, hoping that would result in contiguous blocks used so that I could then re-partition for Boot Camp.
    When booted off the OS X for Intel DVD-ROM disc (10.4.6 - the one that came with my MacBook Pro), if I get out of Installer and into Disk Utility, if I select the internal hard drive and click the Restore tab, I can easily select the hard drive backup image with the button. But the "Destination Disk:" box is only accessible via dragging the disk to the box.
    There's one little problem - there is no Desktop, so the disk(s) do not appear on the Desktop. There is no way to drag the target disk to be restored to into the Destination Disk: box. You cannot drag a disk out from the little sidebar inside the Disk Utility window over to the Destination box. I tried. You can't drag any disk anywhere from that sidebar. It's clear that the only way to drag a disk anywhere is if it's shown on the Desktop in Finder (which isn't running when the installation DVD-ROM is booted from). There is simply no way that I can find to restore a disk drive from a saved backup disk image when booted from the installation DVD-ROM.
    Please tell me I'm ******** and missing something, or if there's a Better Way to do this. (I can't seem to run Retrospect while booted off the DVD-ROM, so I can't restore from my Retrospect full backup of the disk, either. Joy!)
    (I'm really curious if there's a Better Way - especially because it appears I can't boot from an external FireWire or USB 2.0 drive, so I need something that will work in this extremely limited installation DVD-ROM booted environment, I think.)
    MacBook Pro 17" dual 2.16 GHz ;   Mac OS X (10.4.6)   Booted from Mac OS X for Intel 10.4.6 installation DVD-ROM

    You can use an external bootable drive with a MacBook Pro -- check your manual or the built in help. Your problem is that for some reason, you can't install a bootable system on one. There are several reasons why Installer won't enable you to do so: insufficient space, incompatible partition scheme (should be GUID) or file system (should be HFS+ or similar), or wrong installation option selected.
    It is possible this is related to why you can't drag the startup volume to the destination box in Disk Utility. It must be an HFS+ variant file system.
    I think you should check carefully with D.U. the partition scheme of all your drives & the file system format of all the volumes involved. Also run repair disk, as someone has already pointed out.
    The behavior with the Restore function is not normal -- you should be able to drag a volume to the destination box from the list.

  • No external disk encryption available when booted from Lion installer

    Problem: When booting my Mac Mini from a Lion Installer USB thumb drive, Neither Disk Utility nor diskutil from the command line seems able to actually encrypt an external drive. They both seem to be able to convert the drives to coreStorage, just not actually encrypt the drives.
    Background: I was able to successfully preform 3 encryptions from the Lion system on my 17inch MacBook Pro before failing as described above:
    1) I encrypted my main HD in my laptop (using System Preferences > Security & Privacy)
    2) I encrypted my Time Machine backup (Using Time Machine system prefs)
    3) I converted an external 2TB USB drive filled with data (I had a freshly mirrored copy of all this data as backup) using diskutil cs convert -passphrase from the command line
    each of the successful encryptions took about 24hours/Terabyte
    Here is where I tried and failed, step by step:
    ### Failure 1
    I created a bootable backup of Mac OS X Lion on a USB thumb drive. I booted my Mac Mini with it and attached a 2TB external USB drive that I wanted to encrypt. It was a blank drive so I launched Disk Utility from the recovery/installer screen and created 1 partion, GUID, Mac OS Extended (Journaled)
    Then I went to the Erase tab and chose Mac OS Extended (Journaled, Encrypted), provided a passphrase and erased. It took just a couple seconds and said it was done.
    I moved the 2TB external to my laptop running Lion, it asked for the passphrase and when provided the drive mounted just fine but when examined with "diskutil coreStorage list" I see a couple problems (besides the fact I don't believe it encrypted a 2TB drive in 15 seconds)

  • How can I boot from USB 3.0 disc on a Mac Pro 2013

    I am just setting up a 2013 Mac Pro with a 4TB USB 3.0 external drive. I have cloned my boot disc over to it but have problems being able to boot from the USB drive.
    It shows up in the startup disc in system preferences, but when selected as the boot disc and restarted it just boots from the internal SSD. Also have checked booting and holding the ALT key to see what happens but I am just shown the SSD and Recovery disc as options to boot from.
    So it appears I can not boot from a USB disc on my new Mac Pro, is there a solution to this problem?

    You'll need to erase the drive by booting up holding command-option-r keys into your Recovery Volume.
    Use Disk Utility to erase the disk and then Internet Recovery. That will take a while.

  • Migration help... from Powerbook G4 12" 1.5 to Macbook Pro 13" 2009 2.26

    Hi all. My first post here. Finally I took advantage of the educational discount today and bought myself a MBP 13". Coming from Powerbook g4 12" 1.5 ghz, this is a major upgrade. Really Excited about it, but I have some questions.
    When I asked a sales person at the Apple Store about data migration, she suggested I do it with a FW400 and 800 cable. After coming back home I checked some forums and found quite a few people complaining a major headache after using migration assistant and transferring everything from PPC mac to Intel mac. So, I guess my questions are...
    What is the best way to transfer data in this particular situation?
    What should I do with itunes library, iphoto library, ical, and safari bookmarks and stuff if I chose to transfer files manually?
    By the way, I have Tiger on my PB, and Leopard on MBP.
    I'd really appreciate you educating me. Thank you very much for your time!

    Hi
    I tried to do exactly the same as you, transfer from a PowerBook G4 to a new MacBook Pro. For me Migration Assistant failed on every count so had to do it the manual way. I was also Tiger / Leopard by the way.
    First up if your PowerBook will boot into target disk mode then you are halfway there.
    You need to do a few things first.
    If you use iCal export it, use file export, and save it say in your documents folder.
    Contacts again export as vCard, select 'All' in the left hand pane and then select Export, save it again in your documents folder.
    Now with the PB in target mode connect to the MBP and copy across the documents folder. Open iCal on your MBP and import your iCal data. Likewise open contacts and import your vCards data.
    For iTunes copy the iTunes folder from the PB to the MBP.
    For mail navigate on your PB to user/library/mail now drag that to the same location on the MBP.
    For iPhoto, which I don't use, I would suggest copying from the Pictures folder of the PB the iPhoto Pictures folder and iPhoto library to your MBP.
    Safari again navigate on the PB to user/library/safari and copy that folder to the same place on your MBP.
    As regards any applications you are best installing them all afresh onto the MBP, it is the only way they will all work.
    If for some reason target mode does not work use a large external drive if you have one.
    Hope that helps. I am sure if I have missed anything or made a mistake someone will jump in and correct it.
    Hope it all goes well and enjoy your new MBP it is pretty darn good!!

  • HT1296 How can I transfer all my photos from my Ipad Mini to my new MacBook Pro

    How can I transfer all my photos from my Ipad Mini to my new MacBook Pro
    I am facing problem while I connect to my iPad mini with MacBook Pro , it only sync photo from its taken by and from it camera roll only. It doesn't sync all the images... Like my all albums. All photos in library....

    To copy photos that were originally synced from a computer you will need a third-party app such as Simple Transfer which can copy them off via your wifi network. But as photos are 'optimised' when they are synced to the iPad, any that you then copy back to a computer may not be exactly the same as they originally were on your computer.
    You should also be able to copy albums that you've created directly on the iPad via apps such as Simple Transfer (though I haven't tried it)
