5 year old Imac running Snow Leopard with Boot camp.

My IMac will not boot up when I turn on?
The grey apple logo screen and Apple Jingle occurs but I get no desktop or Finder Window and the computer turns off after about 5 minutes of trying to start up.
I inserted Snow Leopard Start Up Disk and tried running Disk Utility - however the Internal Hard Drive is not accesible and shows as being unmounted.
Furthermore - there is NO Start up Internal Hard Drive to reinstall the Snow Leopard OS to.I see my External Drive and Boot Camp partition ONLY.
Could this be a  Hard Drive Failure?
However, when I turn the Computer on and Hold the Option key I have no issue booting Windows via Boot Camp and running Windows XP?
What can I do to resolve this?
I would be so greatful for any help to solve this issue.

It looks like your OS X partition is damaged, but not the hard disk. Although your OS X partition is unmounted, you can select it and repair the disk from the Mac OS X DVD. If it doesn't work, you will have to erase the OS X partition and reinstall OS X

  • I have a 41/2 year old MacBook running Snow Leopard 10.6.  Can I upgrade to Mountain Lion on this machine?

    Can I updgrade an old Macbook to Mountain Lion so I can put stuff in iCloud?  I am currently running Snow Leopard but I've been told this machine will not upgrade to Lion or Mountain Lion.

    First we need to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.
    The Early 2006 model 1,1 Core Duo can only run a maximum of 10.6 Snow Leopard. The models Late 2006 Core 2 Duos 2,1 through Early 2008 4,1 can only run a maximum of 10.7 Lion. The Late 2008 model 5,1 Aluminum Unibody through the Mid 2010 White Unibody model 7,1 can run 10.8 Mountain Lion.

  • Install Two Snow Leopard with boot camp

    Has anyone tried to install on the same Mac two copies of Snow Leopard with bootcamp?
    I want to keep one for general activities and one dedicated and tweaked for audio purposes.
    Thanks to all!

    You can install Windows on its own drive; you can have Mac OS on same drive or different.
    You just can't have Windows OS on a partition that has higher partition number than 4, which includes hidden partitions also.
    I keep Windows on its own hard drive. Then do what you want with your 4-5 internal hard drive bays.

  • Using osx snow leopard with boot camp, optical drive keeps ejecting windows 7 disc

    Upgraded my late 2008 macbook pro from leopard to snow leopard.  Added the max 4GB of RAM and replaced the working 250GB hard drive with a new 1TB hard drive.  Rebooted with time machine from external hard drive.  Now tried setting up Bootcamp to add a Windows 7 partition, but the optical drive keeps ejecting the Windows 7 disc after it spins for a few moments.  The optical drive will read other discs, just not the Windows 7 disc.  How do I fix this problem?

    you need to install the new bootcamp drivers from windows. boot into windows, insert the snow leopard DVD, open it and follow the instructions.

    The subject of buying/selling a Mac is quite complicated.  Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
    SELLING A MAC A
    Internet Recovery, and Transferability of OS & iLife Apps
    Selling an Old Mac:
    • When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
    • Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
    Internet Recovery:
    • In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
    • Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
    iLife Apps:
    • When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
    • Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
    • It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
    SELLING A MAC B
    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
    A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
    B. Clone to an external drive using using Carbon Copy Cloner.
    1. Open Carbon Copy Cloner.
    2. Select the Source volume from the Select a source drop down menu on the left side.
    3. Select the Destination volume from the Select a destination drop down menu on the right
    side.
    4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
    sure to opt for that.
    Destination means a freshly erased external backup drive. Source means the internal
    startup drive. 
    Step Two - Prepare the machine for the new buyer:
    1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
    2, Remove any Open Firmware passwords or Firmware passwords.
    3. Turn the brightness full up and volume nearly so.
    4. Turn off File Vault, if enabled.
    5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
    Step Three - Install a fresh OS:
    A. Snow Leopard and earlier versions of OS X
    1. Insert the original OS X install CD/DVD that came with your computer.
    2. Restart the computer while holding down the C key to boot from the CD/DVD.
    3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
    Optionally, click on the Security button and set the Zero Data option to one-pass.
    4. Install OS X.
    5. Upon completion DO NOT restart the computer.
    6. Shutdown the computer.
    B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because
    it is three times faster than wireless.
    1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
    Utilities window appears.
    2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button. 
    3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
    on the Erase tab in the DU main window.
    4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
    and set the Zero Data option to one-pass.
    5. Click on the Erase button and wait until the process has completed.
    6. Quit DU and return to the Mac OS X Utilities window.
    7. Select Reinstall Lion/Mountain Lion and click on the Install button.
    8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

  • My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive.  Can't get it to run Hardware Test.  Disk Utility says disk OK - files are there. What can I do?

    My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard.   I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host.  But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning.  I can't get it to run Hardware Test - just get the white screen.  If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

    I have an IMAP mailbox that seems to only show mail 7 days on my iMac running Snow Leopard.  However, on my MacBook Pro I can see all old mail that I have not deleted.  It is running the next operating system (Lion?).  Does anyone know how I can get all my old mail back on my iMac.  It is my primary computer and I need some of those old messages.  I have tried to rebuild the mailbox but it has not done anything.

    I have tried to rebuild the mailbox to no avail.  The mailbox behavior says:  Drafts (not checked) store draft messages on the server, Notes (checked) show not in Inbox, Sent (checked) Store sent messages on the server Delete sent messages when (option never selected), Junt (not checked) store junk messages on the server Delete junk messages when (option never selected), Trash (checked) moves deleted messages to the Trash mailbox and (checked)  store deleted messages on the server Permanently erase deleted messages when (one month old option selected).

    IS THE SITUATION HOPELESS
    I used Target mode to transfer files to a new i7  iMac running Snow Leopard 10.6.8 from an older Dual core Intel machine (EMC 2105) also on 10.6.8. but originally Tiger 10.4. The operation was successful and I ejected the disk icon from the new machine and powered down the old machine. When this was restarted the next day there was a grey screen with flashing Mac symbol alternating with a 'no entry' sign and occasionally a question mark.Keyboard and mouse were unusable so k inserted the original instal disc (No.1 for 10.4. with installer 1.0.4) which came with the machine in 2006 in an attempt to boot from this. The ensuing window said this was not possible and now it cannot be ejected.I have tried everything ! It offers Disk Utility and other options like Terminal but that doesn't work either.I 'repaired disk' and that was pronounced o.k. None of the various keystrokes at start up will work, and the computer will only offer the installer disc continually.The only option would seem to be is to erase the hard drive completely from the disc in the machine.I don't want to do this as there is still material which I need to recover. I think the drive has in some way been corrupted by using it in target mode, and I don't know if there are any other options to try.
              Please tell me how to get this disc to eject !

    Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
    No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
    TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
    •  I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
    There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
    On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
    I know that using a cloned drive would work well in this instance.
    I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
    With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive?

    Just downloaded FACETIME on my 4yr. olf Imac running Snow Leopard. When making a call to my friend's Imac all works correctly going both ways. When my wife calls me via Facetime from her Ipad, I cannot click on "accept"- not there? When called by the Imac (newest), the "accept" or "reject" radio button appears for me to click and connect. On my wife's Ipad the two radio buttons always appear when a call actiivates Facetime and comes on?
    There is nothing I can find in "Preferences" in Facetime to turn that on or off. I suspect it has to do with having a more current operating system; that the "controls" are in the operating system? [I'm guessing] It's frustrating getting Facebook calls from several friends on Ipads! Any ideas...VFP

    I suspect it has to do with not having a more current operating system
    Exactly, what Apple is doing is leveraging new features only on newer OS X versions to force you to upgrade OS X to 10.7 or later.
    What they don't tell you is 10.7 or later will NOT run your PowerPC based software, some of it you can't get Intel versions like for perfectly working printers, scanners and games etc. So it can be a very expensive OS X upgrade to 10.7 or later with third party software.
    http://roaringapps.com/apps:table
    Also they don't tell you is the risk in bricking your machine if the update goes badly, so you have to have AppleCare in case that occurs so it's on them to fix it. Else your paying money to replace the logicboard or buying a new machine prematurely.
    A four year old machine can't have AppleCare, it's only good for 3 years from date of purchase new.
    Your machine came with a boot hard drive, it's usually got about 4-5 years of life on it, then it needs to be replaced.
    Also they don't tell you the newer OS X version has more abilities and features that causes your machine to slow down in performance, especially on older machines.
    Also they implement new, idotic and extremely fustrating new user interface features in a arbitrary "you take it or leave it" manner with little or no fall back method.
    So upgrading OS X is a gamble on older machines that otherwise would likely work perfectly fine for the next 5 years if one didn't need to have to mess with it.
    Since Snow Leopard has slightly over 25% OS X version market share, your still good for security updates etc for the next few years if you just want to stay where your at and be happy.
    OS X 10.4/10.5 need to upgrade, 10.6.8 ok still
    The Lions are, well, not so welcome due to Scott Forstall retard UI issues, OS X Mavericks 10.9 is likely going to fix things a bit better.
    But basically what is occuring is Apple is trying to force a faster hardware upgrade cycle with the more expensive products by leveraging features on the smaller devices that expire sooner.
    Apple is a hardware company that leverages whatever it can to get you to buy more hardware, it's why they are as rich as they are.

  • I have an Imac running snow leopard and have recently installed a cannon i-sensys lbp7750Cdn printer since then I can't get the printer working and the air port has lost the DNS servers; if it ever had them!!! but it dose not look happy. Can any one help

    Snow Leopard breaks quite a few drivers - my Canon exhibited the same problem.
    I eventually found updated drivers on the Canon website. You can try that with the HP, but if the all-in-one is more than a year or so old, don't hold your breath.
    You can also try Software Update to see if it will offer new drivers, or failing that go to the Support Downloads site and search for HP updates.
    In fact there's a new one for HP at the top of the list just now.
    You may not necessarily want the latest one, though - check the specs to see if your model is covered; if not, search for the previous update etc.

  • Have a MacBook Pro running Lion and an IMac running Snow Leopard. Want to Back up both images and restore on opposite machine. Essentially swapping images between hard drives. Is this possible and any "gotcha's" to look for? Thanks

    If the MBP came with Lion, it most likely won't boot with SL. Easiest thing to do is create a bootable backup/clone of each to an ext HD, partitioned to hold each on a separate volume, ensure that the original machines can boot with their respective clones, and finally, try booting the other machine with the other clone. Images are useless since you can't boot with them to test them out.

    Thanks!

    Partition your hard drive or add an external hard drive and install Mavericks into it and "dual-boot" to determine which flavor of OS X you are running.  DO NOT install Mavericks over your Snow Leopard environment as Mavericks will destroy it!
    You can then experiment using Mavericks all you want with the ability to boot back into Snow Leopard as needed.

  • Will iMac running Snow Leopard support an iPad2 running io8?

    I have been using a USB cable to sync my wife's iPhone5 and my iPad2 with my iMac running Snow Leopard. (It's a 1st gen Intel iMac and I can't go any farther with OSX versions.) Until this week, I have never had a problem syncing our devices with the iMac. However, when I went to hook up the iPad, it forced me to download a software update for ios7. Looked like everything was fine, though slow in downloading, when I got received an error message (unknown error) that crashed the iPad.
    MY only option at that point was to perform a Restore and Update from the backup on my iMac, which I did. However, the update forced ios8 onto my iPad and wiped out all downloaded photos, music, apps and books. When I go to sync the iPad, all of the settings on iTunes look correct, but the sync button is greyed out and I am not able to download any of the aforementioned files from the iMac to my iPad.
    Help! Is there something I can do to fix this without having to schlep into an Apple Store, where I will be made to feel technologically stupid and inferior by a Genius? Or is the problem that my iMac running Snow Leopard can no longer support the devices running iOs8?

    You could've backed up your iPad prior to the "forced" upgrade which, by the way, you could have cancelled. iTunes doesn't upgrade your iPad, automatically, on its own. You had to click the Upgrade button to initiate the upgrade. You didn't have to do anything with that button. You can just leave it be.
    iOS 8 is garbage on iPad 2 and 3 and even though iTunes keeps giving me the Update button option, I continually choose to ignore it.
    Ignoring the Upgrade/Update button doesn't affect the normal iTunes/iDevice syncing/backing up operations.
    You could've just left that button alone.
    When was the last time you backed up your iPad?
    While there is no way way to revert to a previous iOS version once you upgrade your iDevices iOS, iTunes saves multiple backups of your iDevice and if you backed up your iPad previously to this latest activity, you should be able to restore your iPad from an older  backup that should appear by date when  you plug your iDevice into your Mac, was for iTunes to launch and sync your iPad, then cancel the backup in progress and use the Restore function in iTunes to restore your iDevice from another previous backup version date.
    If your current version of iTunes doesn't recognize your iPad2 under iOS 8, you need to check the iTunes update feature, in iTunes or in OS X Software Update feature in OS X Preferences panel to see if there is a iTunes update available for OS X 10.6.8 Snow Leopard.
