GUID Partition Scheme - Need clean install: can I restore files from TM?

So, here's my problem. I have an Intel PowerMac (first series after the G5) and when I try to install SL I get the following error message: "Can't Install Snow Leopard Since Disk Does Not Use GUID Partition Scheme". I guess it's something related to the fact thet I previously upgraded from an old iMac with a PPC processor (Apple partition vs. GUID partition).
Anyway, accoding to my understanding, the only solution for me is to do a clean install by wiping the HD and re-partitioning it.
Now, my question is: can I use my current TM backup to later restore apps/prefs onto the new SL system? I believe that TM now has an Apple partition scheme that reflects the one I have on Leopard 10.5. Is that right? Will I encounter any problem because of the different partition type of TM?

"Anyway, accoding to my understanding, the only solution for me is to do a clean install by wiping the HD and re-partitioning it."
Right, except that your drive will automatically be erased when you set up the GUID partitiion.

Your TM backup should work. But, there are not many guarantees in life. You could tranfer you TM backup temporarily to your internal and then make a bootable clone of your internal on your external. Afterwards, you could transfer the TM backup back. Then, you'd have two sources from which you could restore items.

  • Reinstalled maverick on Mac mini 2010 now can't restore files from previous backups

    Reinstalled maverick on Mac mini 2010 now can't restore files from previous backups can't even roll back to previous setup

    This is typical Mavericks.
    Was the old backup taken from Mavericks install?
    Did you already start TM from the new install and thus totally foul up and corrupt your old backup?
    You will need to try migrate assistant.. and if that fails you will need to manually pull your files from the old backup if you can still access them.

    Can I restore files from a Snow Leopard Time Machine backup onto Lion?

    Yes, via #16 in Time Machine - Frequently Asked Questions.  But the permissions from Computer A will be restored, too, so the user account you restore them to on computer B may or may not have permission to see or change them.

  • How can I restore files from a time machine back-up of my iMac to an EXTERNAL hard drive connected to MacBook Pro. Using Migrat

    I would like to restore files from a time machine back-up of my iMac to an EXTERNAL hard drive connected to MacBook Pro. When I tried using Migration Assistant it only gives me my internal hard drive as an option to restore to. The internal hard drive on my macbook isnt large enough to store the files.

    Welcome to Apple Support Communities
    OS X can only restore data to the drive where Time Machine backed up files from.
    If you want to restore files from the Time Machine backup onto an external drive, your only option is to access to the Time Machine drive manually (open a Finder window and choose your Time Machine drive in the Finder sidebar), navigate through its folders and copy the files you want to the external drive

  • Unable to change to GUID partition scheme so Snow Leopard can be installed

    Upgrading from OS 10.5.8 to Snow Leopard 10.6.3 on Macbook 4.1 with Intel Core 2 Duo, 2GB RAM. Instructions state "Macintosh HD" can't be used because it does not use the GUID partition Table Scheme. Use Disk Utility to change the partition scheme. Select the disk, use the Partition Tab, select the Volume Scheme, and then select Options.
    Problem: The Options button is grayed out. The Partition Map Scheme is Apple Partition Map.
    Note: Macbook purchased in 2008, but the hard drive was replaced in April 2011. Hard drive Information:
    Name :
    TOSHIBA MK1655GSXF Media
    Type :
    Disk
    Partition Map Scheme :
    Apple Partition Map
    Disk Identifier :
    disk0
    Media Name :
    TOSHIBA MK1655GSXF Media
    Media Type :
    Generic
    Connection Bus :
    Serial ATA 2
    How do I change the partition scheme to GUID?

    This requires that you repartition the entire drive as follows:
    Drive Preparation
    1. Boot from your OS X 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. At this point you can quit DU and return to the installer and install Snow Leopard.
    If you have data you wish to save then you need to backup before doing the above.

  • Clean Install Mavericks and Restoring files

    Good afternoon everyone, I want to do a clean install of Mavericks on my iMac so I have a fresh system to work with.  Having read all the blogs I think I understand how to actually do the clean install via a USB stick but there appears to be a wide range of issues when either trying to restore or transfer files backed up to time machine.  Indeed many blogs cite significant problems even accessing Time machine following the clean install.  Surely this should be simple...but appears not..!
    I'm primarily worried about restoring my email (googlemail), My 500gb itunes library and my significant library of photographs in Aperture. 
    Can anyone advise on the best way to restore files following the clean install using time machine ?  My preference would be to re-install the Itunes and Aperture software from fresh and just transfer or re-import the itunes library and photograps (not easy in Aperture I know) as files...if you know what I mean !...  I'm sure I can manage transfer of all other types of files providing I can get into the back up...
    Any advice or guidance would be really appreciated..
    Cheers

    there appears to be a wide range of issues when either trying to restore or transfer files backed up to time machine
    TimeMachine doesn't have a clean install option. It's why I don't use it and prefer bootable clones instead as they are direct accessible in case I do just want grab files and change permissions to the new account, dumping the rest.
    With timed clones on seperate hardware, makes it easier to revert from a previous OS X version or optimize and defragment your boot hard drive for better performance using a clone, booting from it and reverse cloning.

    To fresh install, you need to backup files manually to external drive (not timemachine), then wipe everything and set the machine up like brand new, with new user accounts, preferably with the same drive name (MacintoshHD) user account names, then return files to each account and do a #6 Repair Users Permissions on the files.
    ..Step by Step to fix your Mac
    iTunes shouldn't be much of a problem, provided you tag the songs in the playlist with the playlist names (attaches to the song files themselves) and use the same drive name and user account name on the fresh install so the pathnames in the itunes database matches where your files are at.
    Aperture shouldn't be much of a problem for the same reason, as long as you copy the contents of your home folders direclty back into the new account folders of the same name, again to match the pathames where your files are at.
    Gmail has a online website, so your emails are there, make sure you have the password. They should redownload to your machine once you set up mail in the new account (with the same name)
    Local email files on the existing system will be erased with the fresh install method because they are likely seure and hidden in the invisible User/Library folder, which doesn't get restored with the fresh install method. (but will with TimeMachine restores as it copies everything)
    Follow the A2 method here for a fresh install of OS X, your just targeting the existing MacintoshHD partition, a full drive wipe isn't necessary.
    Reset your Mac
    You also might want to read this also, it can be used for the fresh install method.

  • Clean install- how to restore files

    After originally upgrading to Mavericks, I realized that I had many old files still in the System/Library from prior operating systems.  I decided to do a clean install to clean things up and remove potentially problematic old software.  I made an bootable USB drive, wiped my hard drive and did a clean install of Mavericks.  I then used my Time Machine backup and Migration Assistant to restore Documents and what I think was labeled as something like Settings.  I manually installed the applications.  I think this may have been a waste of time.  When I look in the home Library folder, it has all the application files and preferences from apps that I did not re-install.  So I don't think I actually ended up doing any cleaning at all.  This is frustrating and I don't understand what happened.  Was it the Settings choice that brought all that stuff back? 
    PS- The clean install did not install the three iWorks applications that I thought were a free part of Mavericks.  Why not?

    I checked and this is even stranger.  There is a second account, and that one has all my old applications (including ones not installed with Mavericks), but not the restored documents from Time Machine.  How did those apps get there?  I specifically told Migration Assistant not to install applications. 

  • How can I restore files from /User/ohthatchris/Library ?

    I've been having a bit of a saga with Time Machine, and I think I'm almost there but I need a tip or two.
    I run TM on a Time Capsule, and have for some time.
    I wanted to do some renovation when I updated my air to Mountain Lion, as follows:
    Final BU with TM.
    Copy of known important files to BU disk (Documents, Applications, etc)
    Wipe HD and clean install of Mountain Lion.
    Renamed computer (had the messy defaunt name Christophers-MacBook_Air...) and created (the only) user account with different name. These changes were for greater compatibility with my employer's network.
    I then restored my important files and applications, and I was pleased that I've free'd up lots of space and I'm running well.
    Restarted TM, and noticed that the sparsebundle was renamed with the new computer name, and the other name was not visible.
    After a little while I noticed that I needed a few files from my old system, specifically my Chrome bookmarks and some recent notes from Notational Velocity. I knew these were in the old TM files, so I proceeded as follows:
    created an account with the same name as my old, pre-Mountain Lion account.
    In System Preferences > sharing I renamed the computer as before (Christophers-MacBook...).
    Entered TM and there were my old backups! This looked great and I felt like I was home free, but no...
    The files I need are in the /User/othatchris/Library/Application Support/.. directories. I can see the new ones in the terminal, but my backups in the TM finder-like window don't include the Library directory. Can I force it to be displayed? Is there some way to interact with the TM backups through the terminal?
    Thanks in advance for any help,
    Chris

  • Can't restore files from Time machine backup?

    I kinda successfully restored my files from Time Machine after a clean re-install of Snow Leopard (Time Machine thought they were new files, though, so backed up the 26 GB... waste of space), but now I'm trying to restore the files of the other user on the computer. In her pictures folder, I can't copy the iPhoto Library because I don't have permission to access it! The same problem occurred on my account too, but I was able to go to my Time Machine drive and manually change the permissions for the files I wanted, which doesn't work on her account.
    I have made a Youtube video of the error:

    Can anyone assist me in restoring the files? That's all I need help in. Thanks

    But if I transfer everything with the Setup Assistant, won't I once again be experiencing the problems I had?
    If the problems were caused by your data. But that's extremely unlikely. It may have been an app, or, much more likely from your description, something corrupted in the Leopard OS. That's one of the problems with upgrading a sick system without knowing what or where the causes are. It's a bit like a brain surgeon operating on himself: if he isn't in tip-top shape to start with, his condition is likely to change, and not for the better.
    Most of us would have recommended first simply doing a +*Repair Disk+* on your internal HD; if that didn't help, installing the "combo" Leopard update; if that didn't work, doing an +Archive and Install+ and re-installing the "combo."
    After a clean re-install of Snow Leopard, my Mac worked fine again (except for the TM trouble). So it probably had something to do with my old files.
    Probably not. Much more likely OSX was somehow damaged. And you got a whole new one.
    How come I could read the files on my external HD and yet not be able to copy the files?
    Time Machine uses special "deny everybody everything" permissions on it's backups, among other things, in an attempt to keep us mere mortals from moving, changing, or deleting things and corrupting them.

  • How can I restore files from empty trash?

    Please someone help me! I deleted my IPHOTO LIBRARY by mistake, and then I pressed " empty trash". Is it even possible for me to recover deleted itens from the trash? I live in Brazil and the closest Apple Store is 5 hours from home. I am not that comfortable with any support companies trying to fix my computer and I can't set up Time Machine alone.
    Any tips?

    I have heard of it, I know nothig about it, Data Rescue is the one I see recommended the most. I had to use Data Rescue once many years ago on a family members machine and recovered quite a bit, but it was a purchased version.
    Try the Wondershare and see if it finds anything (what have you got to lose? as of now you have already lost data) I would try the trial version and see if it recovers anything before thinking about buying the full package.If it does not recover anything then I would not buy it. Maybe then you might try the Data Rescue 3 trial and seee if that recovers anything.
    As for Time Machine back up, you REALLY want to have that on an external drive.You can partition your internal drive for a Time Machine back up, but what happens if the internal drive crashes,? Then you have nothing. With an external Time Machine drive you can replace the broken drive and then restore the data.
    I have 2 back ups 1 Time Machine, and 1 Carbon Copy Clone (the CCC can be booted from, so if my internal drive goes down, I can still start up from the clone. Drives are fairly inexpensive these days, data can be pricless.
    It is not a question of if my drive will crash, it is a question of when, all drives will fail at some point.
    By the way, your english is quite good.
    I hope this helps and you get your photos back, I would be very sad if I lost all of mine.
    Best of luck

    Welcome to the Apple community.
    Rebooting your device is not the same as restoring it, to restore a device go to settings > general > reset > erase all contents and settings. Once you do this you will then be given the option to restore it from a backup or as a new iPod.

  • My hard drive failed...Can you restore files from i-pod

    My hard drive failed. Most stuff was backed up, but not one large folder of MP3 files. All of the songs in question are on my i-pod, but I cannot for the life of me find a way to get the i-pod to transfer the files on to the new hard drive.
    Does anyone know of a way to do this?
    The music was purchased from a site other than the i-store BTW, and re-downloading it all in very manual if I get stuck having to do that. It seems like it should be possible to just send it all back over from the i-pod. I'm baffled.
