Can i install snow leopard on Macbook without using Time Machine?

Hi, I've backed up my files using SuperDuper and made 2 copies of my data on 2 usb sticks. Do I also need to use Time Machine to back up my files aswell, in order to update osx and install snow leopard?? If I've already got my 2 copies of my files on usb sticks, isn't that enough backing up? Any suggestions will be appreciated thanks!

Thanks for answering, so did you manage to upgrade your mac with snow leopard without using time machine? I'd just like to make sure I'm doing the right thing.
To clear up some possible confusion, you don't need any backups (Time Machine or otherwise) to upgrade a Mac from an earlier OS version to Snow Leopard. To do that, just follow Apple's instructions to launch the "Install OS X" app on the Snow Leopard DVD, which upgrades the OS to Snow Leopard without changing your user settings, erasing or changing your user files, & so on. It is an easy process & generally works quite well.
The backup(s) are in case something goes wrong, which is unlikely but not impossible. You should regularly be backing up at least your important user files to an external device whether or not you upgrade ("important" meaning anything you can't afford to lose) since hard drives can fail without warning or other calamities might destroy some or all of the data on them.
At upgrade time, bootable clones like SuperDuper! makes are especially good insurance against any unforeseen upgrade problems: if something goes wrong you can just clone back to the internal drive & return to the pre-upgrade state, without having to hassle with installing anything.

  • Can't install Snow Leopard on Macbook Pro MC700 - 3 beeps after installer starts.

    can't install Snow Leopard on Macbook Pro MC700 - 3 beeps after installer starts (10.6.3 retail). Lion installer starts normally. What's a problem?

    I have the same trouble, I try installing rEFI but when I try start my Pro from DVD doesn't recognize.
    Can I start from USB Memory? with files from SL DVD? or have some thing else?
    I have original DVD of SL 10.6.3, if I buy the latest stable version, can I install? or the EFI firmware with Lion change again?
    I try to use Lion, more than one week but I can't, and some app that I use for my profession, doesn't work, I really need downgrade to SL.
    Really Thanks for any help.

  • Can i revert to snow leopard from lion without a time machine backup?

    can I revert to snow leopard from lion without a time machine backup?

    You can with a Snow Leopard DVD, but if you don't have that or a Time Machine backup there's no way.

  • Can I install Snow Leopard on MacBook Pro 2013

    Can I install Snow Leopard on my new MacBook Pro 2013. I'm so tired of the UGLY grey icons. I keep thinking that the mail or iPhoto window is not the active one because everything is grey.  I use Snow Leopard on my 27inch iMac and love it. Nice RED delete button for mail, etc. Thanks

    Firmware restrictions prevent directly loading any OSX earlier than what came with the system.
    The *only* way around is to load SnowLeopard *Server* (not Client) into a virtual machine (Parallels, VMWare Fusion, VirtualBox).  But that costs $20+shipping/tax for the disk and is a learning curve into SL Server.  And you *still* need your host OSX to run it, and the VM will not most efficiently use the hardware resources.

  • Can't install Snow Leopard on MacBook Pro - DVD won't mount

    I am unable to install Snow Leopard on my MacBook Pro as the DVD won't mount.  This is an early 2008 vintage MacBook Pro, intel core duo...
    I'm using a OS X Snow Leopard install DVD (family licensed).  This DVD has been used to install 3 other Macs in my house without a problem (about a year ago), but cannot be used to upgrade my MBP.  Actually, this disk mounted on the MBP exactly once - inserted with system up, the disk mounted.  Upon running the installed (a year ago), the computer restarted but hung in boot.  After getting the disk ejected and the computer restarted, the disk would never mount again.  I've defered upgrade for a year but at this point need to upgrade my MBP at least to Snow Leopard and possibly Lion.
    The problem doesn't seem to be with the DVD, since it continues to mount fine in other computers, and in fact a borrowed Snow Leopard DVD also will not mount on the MBP.
    BUT ... the problem also does not seem to be with the optical drive in my computer, as it can read & mount the install/restore disks that came with the computer as well as other CDs and DVD ROMs.  Only the Snow Leopard install DVDs fail to mount.
    I've also tried mounting the 10.6 install DVD on my Mac Pro desktop, making it available over the network (ethernet) with DVD/CD sharing.  I can mount the remote disk from my MBP that way, but when I launch the installer, the application launches (its own menus are displayed, I can quit from menu, for example) but does nothing -- no windows open, nothing.
    I've also tried "Remote Install" (again with the DVD made available with the Remote Install MacOS X application on my desktop), but when I boot the MBP with option held down, the remote disk is not available as a startup disk.
    Zapping the PRAM did not help.
    Am off to the store to get an optical drive cleaning kit and a blank DVD big enough to burn a new disk image, but would appreciate any further ideas at this point....

    Solution that worked: Copy the Install DVD to a USB flash drive and boot from that.

  • Can't Install Snow Leopard on MacBook Pro 2010 15"

    Recently my computer has stopped working for one reason or another (i had windows in bootcamp and i removed it, then my Mac OSX lion began playing up). I wiped my disk hoping to install Mac OSX Snow Leopard from the origional disk, and then later windows. I partitioned the disk, installed windows (without the drivers) and then attempted to install Snow Leopard. However, partway through the install (not very far) it just stops and says it cannot instal. A time machine backup with previously worked now does no work and prodices a huge error report. My goal is just to completely wipe my computer and start a fresh with Snow Leopard. Can anyone help?

    I've done that, ive reformatted the disk lots of times, but every time it fails on the install.

  • Clean install Snow Leopard and transfer files from Time Machine?

    Hello,
    I have a computer that is getting s fresh clean install of Snow Leopard. I know how to go about doing this. However, I want to be able to transfer the files back using Time Machine. The Time Capsule has backups from 3 computers. How do I select the right computer files from the backup? The Mac Pro also has a second hard drive intsalled. Is it best to wipe it clean and then load the data from the Time Machine?
    Thanks!

    If you have a second HD with nothing on it, why not do the fresh install on that, then use Setup Assistant to bring over all the files from the HD you've been backing up to TM rather than  TM itself? That way, you have the most direct transfer and a backup of the original too.

  • I can't install Snow Leopard on MacBook after Tiger

    hi everyone,
    i apologise if i created this topic on wrong discussion forum;
    i have a major problem -- there was 10.4.9 Tiger system on my MacBook. so i erased it to install new clean 10.6; i restarted my computer and during the installation there was a message:
    "Mac OS X can't be installed on this computer. This disc requires that Mac OS X 10.5 or later already be installed".
    what to do? i don't have 10.5 and just want to install 10.6;

    Make sure 10.6 you have looks like * Any other Snow Leopard will not install on a Mac that has 10.4.9 installed. It might work better, if you upgrade to 10.4.11 combo Intel first.
    - * Links to my pages may give me compensation.

  • Can't install Snow-Leopard on Macbook pro (Midd 2010)

    Hi there,
    i have i big problem, i can't install a retail-version from snow-leopard (Version 10.6) on my Macbook pro.
    Follow Situation: yesterday i get the Developer-Preview from Lion and install it onto my productiv-system. Not a good idea, i know, but i have a backup and will back to Snow Leopard. So, i try to start the Retail-Version DVD and she start, but only to the gray Apple-Symbol. Then they stop and don't go away.
    I try to reset the PRAM, the SMC, no result. I try to start the installation from a USB-Image, same result. I try to start the installation from another harddisk/partition, the same result.
    When i press cmd-v at the start i can read, that they stop after the load from the extensions.kext.
    I have a Problem, a big Problem, i know. But what can i do?

    You will need to use the system disk that shipped with your unit, the build is most likely different then the one on the retail version
    Then after it is installed- you can use the migration assistant to import your data from your backup.

  • Can I Install Snow Leopard over Tiger, without the Mac Box Set?

    I've just spoken to an Apple advisor in Canada and he told me that I could buy the Snow Leopard CD and install it on my MacBook that has Tiger, and I wouldn't need to buy the Mac Box Set.  He said that since the Mac Box Set isn't available anymore Apple put the full software on the CD instead of just the upgrade.
    However I get a contradictory information on the Apple website.
    What is true?

    And we will all await your reply and your indicating which of us is "Correct" and "Helpful" as you suggest.
    While you are awaiting shipment, you might enjoy reading the following that were published soon after SL arrived on the scene:

  • How can I install Snow Leopard on my 15" MacBook Pro without using its DVD drive?

    How can I install Snow Leopard on my 15" MacBook Pro without using its DVD drive?

    I'm assuming your dvd drive is broken? if you have a thumb drive large enough (8GB or better), you can use another computer to make a bootable image from the install dvd to the thumb drive. then you can install from the the thumb drive.

  • Can't install Snow Leopard on a MacBook

    Hi guys...
    A friend of mine brought me his Macbook to fix it because the hard drive was making sounds and now won't boot.
    The drive in fact is bad, it barely mount, makes noises, etc.
    I've replaced the internal hard drive for a Toshiba 320gb SATA 3.
    The thing is that apparently the DVD doesn't recognize my drive and of course, i can't install Snow Leopard.
    My question is, is this a problem with the new drive?. I believe that being a SATA3 could be causing the problem.
    Second question... Can i install Snow Leopard (somehow) using my Mac mini?
    Thanks so much and i hope you can help me.
    Regards.
    Francisco.

    Hi!!
    >I've used another internal hard drive and installs correctly<
    Using the DVD installer?
    Yes
    So it boots with another hard drive in there but ejects when you put the Toshiba in there?
    Yes but it only make sense if the DVD would create a temporary partition or something in order to install the OS.
    >Could it be that the drive is SATA3? <
    Even so it would be downwards compatible.
    I though so too
    >or maybe the hd is bad?<
    That would make more sense.
    I'm going to clone the installation that went OK in order to see if it's actually my internal drive the problem.
    Could it be the manufacturer?
    Thanks so much and i'll let you know.
    Regards.
    Francisco.

    Best regards and merry christmas

    Apple figures that having supported PowerPC code for the last 6 years is enough so they dropped it.
    Why should they have to support some that old forever? It doesn't make good business sense to support some that so few will use.
    If you must play those games, my suggestion is to get an older Mac that will support PowerPC. It is going to be a difficult task to get Snow Leopard to run on a new Mac.

  • I have a new time capsule, want to use it in conjunction with iMac G5 and MacBook; laptop runs Snow Leopard  but G5 can't install Snow Leopard, is stuck at OS 10.4.11.  Am I doomed?  Can anyone advise me?  Thanks..

    I have a new Time Capsule, want to  use it in conjunction with an iMac G5 and a MacBook.  MacBook runs Snow Leopard, but G5 (lacking Intel processor) can't install Snow Leopard, is stuck at OS 10.4.11.  Am I doomed?  Will appreciate any advice.  Thanks.

    you should still be able to get a copy of Mac OS X 10.5 (Leopard), which should run on your G5.

  • Cannot install snow leopard in macbook pro early 2011. disk is rejected. what do I do?

    Unable to install snow leopard in macbook pro early 2011. When I put in the disk, the computer does not accept it. What can I do?

    lord1908,
    some Early 2011 MacBook Pros originally came with Snow Leopard installed, and some originally came with Lion installed. If yours originally came with Snow Leopard installed, then you should be able to install Snow Leopard from its model-specific grey Mac OS X Install DVD. (The white retail Snow Leopard DVD can’t be used with it; it was made for use with earlier models, which originally came with either Tiger or Leopard installed.) If yours originally came with Lion installed, then it won’t accept any Snow Leopard DVD; instead, you’d be able to use OS X Internet Recovery to download and install its original version of Lion from Apple’s servers.
