It will be the one on top of the list.  In this example it is BARBAROSSA:

The name should be the same as the HDD icon on your desktop, usually Macintosh Hard Drive.

    I purchased my Macbook Pro in November 2011 and just installed mountain lion but do not have the power nap option.. anyone know why?

    It is for the MacBook with built in flash storage.

    4. Power Nap requires a Mac notebook with built-in flash storage. May require a firmware update.

  • Erase and reinstall 10.7 Lion

    Hi. I have a MBP mid 2009 running on Lion. If I do a erase and reinstall, do I need the snow leopard DVDs during reinstall?

    No.
    You can reformat (erase) the disk and restore OS X using OS X Recovery
    Don't forget to backup all important data before reformatting the disk.

  • Hard drive absent in disk utility - want to erase and reinstall MacOS

    Hi there. Any help would be most gratefully received.
    I have a Power Mac G5 Dual 2Ghz with 2GB RAM, one internal HDD (250GB serial ATA 7200rpm - the original one), two external HDDs and a Philips 170B display, running (or not) MacOS 10.39.
    It was working fine yesterday but on startup this morning it hung for a while on the grey Apple logo and progress "clock" then froze on a blue screen.
    I tried removing all cables except display and keyboard/mouse and restarted a few times but to no avail.
    I tried entering safe mode but it wouldn't work. Upon subsequent attempts at startup it took me (instead of the blue screen) to the flashing question mark/finder folder screen.
    I then booted from my install CD and tried to run Disk Utility to repair the disk. Disk Utility recognised the disk and allowed me to select it. But when I tried to verify it, it failed and told me to repair. When I tried to repair it told me "invalid b-tree node size".
    I then tried running the Apple Hardware Test CD. It found no faults at all in the full test of the system.
    All of my data is stored on my external HDDs so my next thought was to erase the internal HDD and reinstall my software. (I use the Mac solely for Video editing and the only applications I have installed - in addition to all the basics - are the Apple Production Suite.)
    However, this time when I booted from the install CD, Disk Utility would not recognise the internal HDD. The only thing I had done since it had recognised it the last time was to run the Hardware tests. In addition, since running the hardware tests, the HDD started making a strange noise whenever the Mac was on - like clicking with almost beep-like access noises.
    The last time I tried restarting and booting into Disk Utility, the clicking began again and then eventually stopped. But still no evidence of the drive in Disk Utility.
    Soooooooooo. I don't need to save any data on the hard drive. I have all my software and OS discs. I just want to wipe the drive and start afresh (assuming this is the best course of action?). But I am unable to do so because of this new development in my attempts to fix the problem: the unrecognised hard drive (coupled with the strange noises).
    If you have any ideas, please do get in touch. I'm pretty broke at the minute and I'm trying to find a solution without having to purchase a new drive. Obviously, if this is the only solution, then I'll have to bear that cost. But since it has recognised the disk just a few steps before, I'm hoping there's a way back.
    Yours in optimism

    I am not sure about battery, I still use G4 MDD which is unplugged for months, was always off at night (UPS was off) and still works.
    But I would always use both SATA drive bays, and I think you need to invest in one or two new drives.
    For now, try disconnecting your drive and see if you can boot from external drive and CD/DVD.
    Also see if you can get into Open Firmware.
    Resetting PMU would also be worth while when you get in to disconnect your hard drive (I think 3 yrs is more than enough for any OEM drive, too).

  • Erase and reinstall without start up discs.

    I want to erase and reinstall my MacBook Pro which is 10.6.8 but I can't find my start up discs anywhere. Is there a way I can do this?

    No. To do an erase and install requires a Snow Leopard DVD or a bootable backup on an external drive or another Mac with Firewire ports running Snow Leopard.
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s MobileMe service; fees and
               terms apply.

  • Erasing and reinstalling my mac pro hard drive

    I have an older Mac Pro (2006 I think).
    I want to erase and reinstall the hard drive. Once the disk is clean, is there a way to install OS directly to mountain lion? Or will I have to install from an ealier complete set of physical disks?

    If it shipped with 10.4 and is a 2007 or earlier Mountain Lion is not supported, only up to Lion.
    You download and save the Lion installer first and would need to have 10.6.8 to access the App Store.
    Leave what you have as is, and just install a new system to another of the drive bays.

  • HT1202 I get how you can transfer purchases from a device to computer but what about the hundreds of songs on my iPad that were from CDs and non purchased? How can you move them from iPAd to computer if it wants to erase and sync?

    I am needing to transfer ALL content, not just purchased, to new computer and it wants to erase and sync because device is associated with another Library. Please help!

    What was the source to get that content onto the iPad?
    There has to be a middleman to get from CD to iPad - use
    backup of that to get content to new computer.

  • Every time i plug my iphone into computer it wants to erase and sync

    iphone was originally linked to my laptop... however i never transferred anything from the laptop to the iphone.  i now want to use my desktop to transfer music.  so i plug in the iphone, click the checkmark next to sync music. it says that the iphone is currently synced to another library and do i want to erase and sync?  so i erase and sync and pick the music i want and transfer it to my phone.  I unplug the phone, plug it back in again. in itunes it shows the music sync as unchecked... so i click the box to sync music and it says its associated with another library and it needs to erase and sync.
    i have done this 4 times now. and everytime it wants me to erase and sync even though i just did it on the same computer with the same i phone 3 times in a row.  i don't get it, why won't itunes/iphone sync with the new itunes library on my desktop??? what can i do to fix this issue?
    i'm using newest itunes 11 on windows 8.1 computer.  the computer has not been authorized... does this make a difference as to why the sync won't stick?
    BTW i also hate how apple makes you sync your phone, android is so much easier to just plug the phone in and transfer your music/videos manually.  never have a problem doing that.  Only when apple tries to make it so easy it gets way more complicated than it needs to be!

    Hi joy145,
    If you are having issues syncing and would like to manually manage your content, you may find the following article helpful:
    Apple Support: Managing content manually on iPhone, iPad, and iPod
    http://support.apple.com/kb/HT1535
    If you are still having issues or continually prompted to erase and sync, you may want to try restoring your iPhone to factory settings before moving your data over (either via syncing or manually):
    Apple Support: Use iTunes to restore your iOS device to factory settings
    http://support.apple.com/kb/ht1414
    (Note: Restoring iOS software deletes all your data and content from your device, including songs, videos, contacts, photos, and calendar info.)
    Regards,

    - You can only syncewith one iTunes library.  It sounds like you change libraries such as changing the computer.
    - As you may know you can transfer iTunes' pruchases to a new computer by:
    iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
    - This previous discussion provide info on how to move other music from an iPod to a computer:
    Best iPod to PC
    - You can also manage music with different computers by:
    Using iPhone, iPad, or iPod with multiple computers
    - If you need more help please provide more information.

    The phone usually can hold 24 messages before the voicemail is full, but now I have only 21 and it's saying it's full.
    I think your Voice mailbox goes by time, not # messages, so if one or two of the messages is longer, then it would be "full" faster.
    Go to youmail.com and follow the directions to set up youmail.
    Just curious - why do you need to save 20+ messages?  Once I deal with them, I delete them.... and I rarely have more than one or two \saved messages....

  • I transferred my files, including iTunes, to a new computer. When I go to sync, it says I'm still synced with the old, do I want to erase and resync. AND then it says not enough space. What to do?

    I transferred my files, including iTunes, to a new computer. When I go to sync, it says I'm still synced with the old, do I want to erase and resync. AND then it says not enough space. What to do?

    Pictures, assuming they were taken with the device, can be copied off at any time.  This has nothing to do with syncing.
    If the pictures were instead synced to the device via iTunes, they are not the original images.  Instead, they are optimized copies of the originals for display on the iPhone.  There is software that can extract them, google it.
    Where is the backup of the computer?  And before you ask, the iPhone, like all iDevices, is not and has never been a backup device.

  • I want to erase and "reformat" a 1TB external drive?

    I want to erase and "reformat" a 1TB external drive to use it to back up my iphoto and itunes library.  I don't want to use time machine.  I have gone to utilities, disc utilities, erase.  Then do I chose Mac OS Extended ( Journaled) or Mac OS Extended or any of the other choices?

    You are on the right track. Choosing OSX extended is the best option if you only intend to use the Ext HD with your Mac. If you want to use it to share files with a Windoze PC then you should choose FAT32, but if you do you will have difficulties transferring larger files (over 3-4GB). Also, it is best not to partition the drive. It is unnecessary.

    Copy your iTunes Library from your Old computer, or it’s Backup, to your New computer...
    See Here for one way
    iTunes: How to move your music to a new computer
    Or...
    From your Old Computer... Copy your ENTIRE iTunes FOLDER to an External Drive... and then from the External Drive to your New Computer..
