  • Transferring Time Machine access from iMac to Macbook Air

    I have a five year old iMac and recently bought a MacBook Air. I want to eventually get rid of the iMac and use the MBA but I still want to have access to Time Machine files that backed up the iMac using my MBA.
    I'm thinking I can probably do this via Migration Assistant, from the Time Machine drive to the MBA. The only problem I foresee though is that my MBA has a fraction of the hard drive space of  the original iMac and therefore, I can't do a straight clone.
    Is there a way I can set this up so I have the iMac fully backed up to Time Machine and then make those files accessible via the MBA, thereby eliminating the need to keep the iMac simply for the HD?
    Thanks.

    Thanks for your clarification questions.
    The Time Machine backup is on an external drive (firewire/USB).
    The goal would be to migrate both user accounts as well as applications and settings. Obviously, I can't port everything over given the HD size limiations on the MBA but I think I've figured out what's essential and what is not.
    #1 makes sense (though would likely require the purchase of a new external HD).
    #2: How would I "replace that account with the User Account on your Time Machine backup"? Is this the same external drive that the Time Machine files already reside upon? Or a new one?
    #3 & 4: I already considered both of these but I think that leads back to #1 (i.e. the likely need to have another HD)
    Thanks again.

  • How can you repair a MacBook air when it won't start properly?

    My MacBook Air is just over 3 years old and thus out of warranty.
    It gives a message that says the Preference Pane cannot be opened. Mostly the screen is black but sometimes (oddly) Adobe Bridge has a window ... but I cannot move to any other application.
    1) is Genius Bar only available if your product is under warranty?
    2) is there no way to check it? No recovery shows up when I option-restart.
    Advice would be appreciated. the closest Apple store is an hour away.

    Backup your files. If you have a 2010 model that came with a set of two software discs then do the following:
    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. 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 the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1. If you wish to upgrade to a later version of OS X, then do so on the App Store.
    If you have the 2011 model then do this:
    Install or Reinstall Yosemite, Mavericks, Mountain Lion, or Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    How to Clean Install OS X Yosemite
    OS X Mavericks- Erase and reinstall OS X
    OS X Mountain Lion- Erase and reinstall OS X
    OS X Lion- Erase and reinstall Mac OS X
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • Time capsule & external drive - Time Machine Back-up of two macbooks - Can't connect

    My wife and I each have a macbook pro and want to back them up using Time Machine.  I had my macbook and a time capsule for a while before she got her laptop, so I backed mine up to the Time capsule - no problems.
    Now, I have purchased an external drive so that mine backs up onto the time capsule drive and hers is set to back up on the external drive due to space limitations.
    However, with hers set up, my macbook can no longer see its original back-up file.  Meaning that hers will back-up all the time, but mine can't ever connect.
    Is there a different configuration / setting that I should try to make this work?
    Help is greatly appreciated!

    I don't follow how the change on one laptop can affect the other, unless they are networked together in some way.. how is the second laptop connected??
    I suggest you reset Time Machine.. and rediscover the TC..
    A4 here http://pondini.org/TM/Troubleshooting.html
    If you upgraded to Lion or ML recently that is the issue.. reboot the TC and maybe the whole network to clear the old IP addresses.

  • 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.

  • The error that I am getting is this "Time Machine can't use the disk image because it can't be written to."  Any ideas on the fix for this?

    The error that I am getting is this "Time Machine can't use the disk image because it can't be written to."  Any ideas on the fix for this?  When I go to the Time Capsule my Macbook Pro shows that it is locked, I think I did something wrong, but can't figure how to unlock it to see if that fixes it.

    As far as we know, Time Machine cannot write to a disk image. It needs to write directly to the Time Capsule disk.

  • Time Machine Can't find Drive connected to other networked Mac

    I have a Drobo external drive array connected by firewire to my primary home computer - a Mac Pro.
    For the last year I've backed up two Macbook Pros (mine and my wife's) to this Drobo using Time Machine (The Mac Pro is always on and the laptops backup through the home network, through the Map Pro, to the Drobo).
    I recently did a fresh reinstall of Lion to all 3 computers.  Now for some reason Time Machine can't kick the backup off.  It gives me a "Can't backup - the backup drive us not available," or something like that.
    A couple of key points:
    * Through the primary computer, I have opened read/write file sharing permissions for all drives, including the FW connected Drobo
    * From the laptops, I can see and read/write to the Drobo through Finder
    * Through Time Machine preferences, I can select the Drobo as a backup destination -  it's only when I kick off the backup that I run into the error.
    * If I create a test admin account to try, I get the same problem when trying to back up.
    *  As a safegard, I have run a manual backup successfully to a separate external drive (mobile g-drive)
    What am I missing?  Seems like it's gotta be something straightforward - perhaps on the laptop?
    Thank you,
    -bh-

    no - sadly not:)
    Okay - I gave it a shot - no dice - here's a screenshot -
    Couple of interesting things (at least to me and my limited knowledge...):
    * the reset of Time Machine seemed to reset how my laptop connected to the primary computer - defaulted to connecting through AppleID rather than Administrator
    * Perhaps I'm using wrong Admin credentials in my File Sharing preferences?
    *  When I connect to the main Mac Pro ("connect as...") with Admin credentials...though I see the drives and can read/write, it still shows a "connection failed" message above.  sending one other screenshot to show you.
    Thanks for all your help,

  • New TC but now Time Machine can't find network backup drives

    I had a 2 GB TC replaced under warranty (many thanks to LaPastenague who suggested I may be able to get a replacement under warranty).  Configured the TC using Airport Utility, and after a bit of messing around (had to delete and re-find the USB printer) everything seemed to be working fine.  However ....
    I have a MyBookWorld network drive as an alternate Time Machine backup disk, and my MacBook found both the TC and MBW and backed up to them alternately just fine.
    However on another MacBook I removed the MBW drive as a backup disk in TM preferences, and now I can't add it back to that Macbook's list of backup drives.  I get the "can't find that server" error dialogue.  Which is crazy because the other shares on the MBW drive are visible - it's just the backup partition (WD_Backup) that isn't found.  I figure it's trying to connect to the IP address of the previous TC, which probably changed when I replaced the TC, or something.
    Help please !
    TIA ... John.

    Manually mount the directory in finder.
    This is so much more important on Mavericks than it used to be due to its default to SMB networking.
    I guess I also do not know if you should mount this via AFP or SMB but try both.
    So in Finder.. Go.. connect to server.
    Type in the actual name or IP of the device.
    AFP://MBW.local/WD_Backup (where MBW is the network name of the device. local is the domain (assuming it is connected to the TC))
    No luck try AFP://MBWIPaddress where you simply type in the IP.
    You might find it is easier to pick up the directory from the other Mac where it is working.
    Click on Get Info and look at the directory URL info.
    If no luck use SMB://MBW.local etc.
    Come back to us if it still does not show up.

  • Time Machine on Lacie to new Macbook Pro (Lion)

    My 6 year old Macbook Pro, running Snow Loepard died and I replaced it with a new model, running Lion.  I have the Time Machine backup from the old Macbook on a Lacie external hard drive.  The questions are; can the Time Machine files from the Lacie drive be put on the new Macbook?  Are the needed drivers installed in the new Macbook?  Are there any tricks?  Are there special cables needed?

    Have a read here How do I set up a new Mac from an old one, its backups, or a PC?
    As for the cables, since both MacBook Pros (the old and the new) have the same ports avaiable for connecting external harddisks -> USB and FireWire
    At worst you need a FireWire400-to-FireWire800 cable.

    I just started getting the same message.  I'm using a Western Digital My Book 3TB disk.  Normally I have the backups done with the disk attached to Airport Extreme.
    I hate to have to tell you this, but backing-up that way is unreliable and not supported by Apple.   See:  Using Time Machine with an Airport Extreme Air Disk.
    Backup failed with error: The target disk image volume is read-only.
    Most likely, you got this message before all this started:
    What that doesn't explicity say is, the backups failed the verification.  When that happens, Time Machine marks the sparse bundle as damaged and won't back up to it anymore (even if Repair Disk can't find the problem).  See #C13 in Time Machine - Troubleshooting for details.

  • Using my Time Machine backup on my Brother Macbook

    Hi guys/girls.
    My brother HD recently died on his Macbook Pro (15" Mid 2009 I think) he has fitted a new HD to the machine and all if running fine. I just want to know if I use my saved Time Machine can I import that onto his mac? He is running 10.6.8 and i'm running a Mid 2012 13" 10.8.5. Sorry if this has been covered i'm new to the Time Machine function.

    You can, but you should not. The way to restore your Time Machine backup to your brother's Mac is by using Migration Assistant (in /Applications/Utilities), but you are using a later OS X version than your brother. If you restore a backup using Migration Assistant, you will damage OS X in your brother's computer.
    In order to restore one of your backups safely, your brother should upgrade to OS X Mountain Lion or OS X Mavericks. See > http://www.apple.com/osx/how-to-upgrade

  • IMovie Time Machine backup of my old Macbook Pro

    Hi, I have a Time Machine backup of my old Macbook Pro. I need to edit one of the iMovie movies from the back up. How can I import all the data from my old iMovie to my new macbook Pro so I can edit it?

    What version of iMovie were you using on you old machine?
    What versions of iMovie do you have on your new machine?
    Do you still have access to your old machine?
    Assuming you were using iMovie 9 you need to copy over two folders called "iMovie Projects" and "iMovie Events" and put them at the root level of an external hard disk or in <user name> / Movies.  However you need to open these in iMovie 9.

  • Would Super Duper!/Time Machine function w/ Littlle disk - MacBook 2.0

    RE: Would Super Duper!/Time Machine function w/ Littlle disk - MacBook 2.0
    Thanks to all who read on...
    The situation at hand is this...
    I have 2 Lacie Little Disk Drives 120 & 250 GB, that I once used to make FW clones from iBook G4 to backup my information , applications etc.
    1.0_How would I translate such operations with a substituted Macbook 2.0 Aluminum?
    1.1_It seems the Macbook doesnt have any FW ports, nor is their any reliable source stating a T-100-to-Firewire adapter would work with OS 10.5.6...?
    THAT being said, the USB ports do recognize the built in Lacie Hi-Speed 2.0 extractable USB Connector. (See Topic: Little disk on a hub with Macbook?)
    I have given Super duper a try to make a Leopard (10.5.6) over this Hi-speed USB 2.0 and it seems to have made the backup, although I haven't as of yet actually used this clone -yet.
    2.0_How can I take advantage of Leopards Time Machine instead of Super Duper!?
    2.1_Whilst still possibly incorporating the usb/firewire Lacie Little disks? (As once sod on THIS very site)

    I'll agree with the previous two posts. With TimeMachine, you always have your most current and previous versions of data backed up. With SuperDuper (or CarbonCopyCloner), your data is only as current as the last time you ran a backup. The major benefit of SuperDuper (or CCC) is that you can create a bootable backup. If you need to restore your system from a TimeMachine backup, you'll need to start your system from your install DVD which will allow you to restore your system from your TimeMachine backup. I think the biggest benefit to having an external clone is in case your internal drive fails. Since you can't boot from a TimeMachine backup, if you have a hard drive failure, you're out of luck until you get that drive replaced. If you have an external clone, you can simply boot up from that which will allow you to continue working until you can get your internal drive replaced. As has been mentioned, both have their benefits and using both to compliment each other is your best option. Since TimeMachine is part of OS X and both SuperDuper and CarbonCopyCloner are free for full clones (actually, CCC is completely free for all functionality now), there's really no reason not to use both.

  • Time Machine can no longer write to drive

    I have been using Time Machine to back up my iMac G5 for over a year. About two weeks ago the computer started acting really strange so I actually restored the entire system from my Time Machine backup. Everything was working great until today. The external hard drive that I've been using all this time is suddenly "read only". How do I change it back to "read/write" so Time Machine can access the hard drive properly?

    It's very important to know exactly what you or the computer was doing just before this happened. Usually, things do not happen on their own.
    How do I change it back to "read/write" so Time Machine can access the hard drive properly?
    Changing it back when it's not clear why it changed in the first place is not always a good thing to do for several obvious reasons.
    Right-click on the TM drive icon and select "Get Info"
    Under Sharing & Permissions, you should see:
    Your name (Me) Read & Write
    (unknown) Read & Write
    everyone Read only
    Post back what you see and we can attempt to proceed.
