I want to upgrade from snow leopard to Mavericks, but only Yosemite is available!!

How do I upgrade snow leopard to Mavericks on one of my older macbooks? I note that Mavericks is no longer available via the App store, only Yosemite, and I do not want the latter. My latest macbooks all have Mavericks pre-installed, and I want parity on all.

OS X 10.9 Mavericks is no longer an available, downloadable OS version.
You can choose to decide and download the free OS X 10.10 Yosemite OR pay to download either OS X 10.7 Lion  or OS X 10.8 Mountain Lion.
Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.
OS X 10.7 Lion system requirements
Purchased emailed download code here.
http://store.apple.com/us/product/D6106Z/A/os-x-lion
To use OS X 10.7 Lion, make sure your computer has the following:
An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended)
7 GB of available disk space
2 GB of RAM
To install OS X  10.8 Mountain Lion, 10.9 Mavericks (free upgrade, but currently unavailable) or OS X 10.10 Yosemite (currently available free upgrade) you need one of these Macs:
OS X 10.8 Mountain Lion purchased emailed download code here.
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)
8 GB or more of available space
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe  could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty  here.

If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall these apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest versions of OS X by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password and if you purchased a download code, input that code.
You can then begin the download and installation process of installing the newer versions of OS X from the Mac App Store.
Good Luck!

  • I am new to mac's and have upgrade from Snow Leopard to Lion but......

    I am new to mac's and have upgrade from Snow Leopard to Lion but not all my application will work. Is it save to reinstall using original snow leopard dvd and does it wipe all my other application like apature? I am in a panic over this, any help!!
    I came across this online and i want to know is it safe to do this:
    Backup your User folders to an external drive. This should preserve your documents, photos, music, etc. If you store those things in locations not in the User folder, make sure to copy those over too.
    Insert the Snow Leopard disc. Restart your Mac and hold down C to boot to your DVD drive.
    Go to Utilities in the menu bar once the installer pops up and select “Disk Utility.”
    Find the drive in the sidebar where Lion is installed, select it and navigate to the Partition tab.
    Click on the drop down menu under Partition Layout and select “1 Partition.” Hit Apply.
    Now navigate to the Erase tab and make sure “Mac OS Extended (Journaled)” is selected, then hit Erase to delete all data on the drive.
    Quit Disk Utility to get back to the Snow Leopard installer and proceed with the install.
    Restore your User folder and documents from your backup.
    Run Software Update to get everything current, install your apps from your original install media and update those as well.
    if any one can help me that would be great, thanks Mike

    Before you do that why not do this first:
    Repair the Hard Drive and Permissions
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    To boot from the Recovery HD restart the computer. After the chime hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    If this doesn't help, then you can proceed to reinstall Snow Leopard as follows:
    Downgrade Lion to Snow Leopard
    1.  Boot from your Snow Leopard 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Quit DU and return to the installer. Install Snow Leopard.
    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
    This will erase the drive so be sure to backup your files before doing this.

  • Can I still upgrade from Snow Leopard to Mavericks, with Yosemite out?

    Hi there,
    my girlfriend is running Snow Leopard (10.6.8 I believe) on a MacBook 2009. Now she finally wanted an upgrade to a newer OS. However, I've read in several reviews that Yosemite is not running very smoothly on some older Macs. So I thought upgrading to Mavericks might be a better deal.
    So my question is:
    How can I upgrade from Snow Leopard to Mavericks? Apparently you can't do it over the AppStore, since you can now only download Yosemite. Is there another way?
    Thanks!

    Nope. Mavericks is no longer available for download unless you had downloaded it in the past. If Yosemite doesn't do well on an older Mac, then neither will Mavericks. Consider rolling back to Snow Leopard.
    You may try calling Customer Service: Contacting Apple for support and service - this includes international calling numbers. They may be able to help you with getting Mavericks for now.

  • I upgraded from snow leopard to mavericks only to find that my backup files of all my CS3 indesign, illustrator, photoshop wo't run, how do I uninstall mavericks and get my old system back

    I upgraded from snow leopard to mavericks only to find that my backup files of all my CS3 indesign, illustrator, photoshop wo't run, how do I uninstall mavericks and get my old system back.  I retired from graphics a few years back but still have old clients I do work for and maintain files for.  Would not have upgraded if I had known of the incompatability.

    You did not due any due dilligence to investigate if your legacy apps would run, you should upgrade your apps. However if you feel you have to downgrade back to SL then click

  • Mail folders missing after upgrading from snow leopard to mavericks.

    I seem to have lost my mail folders after the upgrade from Snow Leopard to Mavericks.
    Are they hidden? if not is there any way to recover them from TimeMachine?
    thanks

    sorry, I found them: by clicking "On my Mac" - show.

  • HT6065 I upgraded from Snow Leopard to Mavericks OS X, and lost all of my "on my mac" mail boxes.  How do I restore them?

    I upgraded from Snow Leopard to Mavericks OS X, and lost all of my "on my mac" mail boxes.  How do I restore them?

    The answer was more complicated.  I had to have an Apple Care tech help me onscreen.  Had to go to Time Machine to restore (which I had tried, but couldn't find the right files to import.  The Mail icon was barred).  They helped me find them.  It was very complicated, with many steps involved.  I never could have figured it out on my own.  Even the tech was not sure how, or if it would work. And it took about 1/2 hour for the stuff to download. But, the problem was solved eventually
    .  Thanks again for your help!

  • I need rosetta and don't want iCloud on my MacPro. Why should I consider upgrading from Snow Leopard to Mavericks?

    I understand that the newest OS X is Mavericks. I have refused to upgrade from Snow Leopard because I need Rosetta for some older applications I still use. In addition, I absolutely refuse to use iCloud (or anyother cloud service that uses servers resident in the USA). Can anyone give me a good reason to upgrade to Mavericks?

    Your other option is to run a virtual machine using Snow Leopard server.
    Parallels
    VirtualBox
    VM Fusion
    Snow Leopard server for use with the above. Call 1-800-692-7753 and order part number MC588Z/A. Cost is $19.99 + sales tax and shipping.

    If you have not previously purchased Mavericks from the Mac app store, then no. It is no longer available. Yosemite has the same system requirements as Mavericks and is a free upgrade from the app store.

  • I want to upgrade from snow leopard to Yosemite all at one time.  is this a good idea on my imac 8.1 using OS X 10.6.8?

    I am using snow leopard on a mac 8.1  can I up grade in one step to Yosemite or should I up grade to an earlier OS first?

    Yes, you can jump to Yosemite directly. Before you do be sure your computer is compatible:
    Upgrading to Yosemite
    You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
    Upgrading to Yosemite
    To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

    I would also suggest you do the following before installing the upgrade:
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard 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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

  • Upgrade from Snow Leopard to Mavericks: Volume cannot be used as a start volume

    Hi there!
    I'm having a triple boot Mac-Linux-Win on a 2010 iMac. Each is on a partition. From Snow Leopard, I'm trying to install OS X Mavericks via App Store. The install Mavericks button has been added to my dock after the download completed.
    However, when choosing a target volume, it says that my current Mac volume may not be used as a start volume. File system is Mac OS Extended (Journaled) and I'm having 168 GB free space on it. Partition table is GUID.
    What's wrong?
    Cheers,
    Kalsan

    You are never going to have the option to repair a disk if you are booted from the same disk.
    I think the place to start is boot off your Snow Leopard DVD install disk by holding down the C key on boot up.
    Under Utilities drop down menu  you will have access to Disk Utility.
    From  here you will have the option to repair Disk (ie not grayed out.)
    option: Either insert and wait for the Mac OS X Install DVD window and double-click the Install icon;  or power down, then start up while holding down the "C" key.  Either way, that takes a few minutes.

  • Want to upgrade from snow leopard to lion, need to purchase an external harddrive to b/u my stuff.  will formating for snow leopard be ok when uploading to the new system (lion)?

    oh sorry, I thought that was where we put the question   I am on an extremely tight budget, but since I do shift work, I wanted to use the iCloud funciton to keep my calendars uptodate on my pc/mac mini/and iphone. Wish there were a way to do it for free on my snow and snow leopard OS, but sinc e I cannot, I am wondering about formatting the external harddrive (which I have to purchase). If I format for the snow leopard, will there be a problem re installing the information into the new snow leopard OS machine?  Also, I am wondering about the older Mac Pro I have that is the OS before snow leopard (Snow, I believe) will I be able to use this same HD for backing it up to upgrade it (at a later date)?
    Thank you for your help.
    Deb

    so sorry, I mean uploading information from the back up (ex HD) onto the new Snow Lion OS.  (and later doing the same with the Mac Pro which is the system before snow leopard.)  TY

  • Upgrade from Snow Leopard to Mavericks failed - disk is damaged and can't be repaired.

    Hello,
      I'm afraid the answer is exactly what I don't want.  But here is my situation.
      I've been trying to download and install Mavericks - I was running Snow Leopard.  My system was working fine - I wanted to upgrade so that I could run a game on it - but it required Mavericks. 
      Finally, it looked like Mavericks was installing.  Once I restarted my computer, I got the following message:
    "Install Failed. OS X could not be installed on your computer (there's a big scary yellow triangle with an exclaimation point in it below this). The OS X upgrade couldn't be started because the disk Macintosh HD is damaged and can't be repaired. After your computer restarts, back up your data, erase your disk, and try installing again. Click Restart to restart your computer and try installing again."
    Every time I restart, I get the same message, I can't back up my data and erase my disk like it wants me to; it won't let me. I can't get back to my normal computer. I've tried restarting in Safe Mode, but it doesn't work - it just keeps restarting over and over again. If my computer is really this determined to not let me have Mavericks, fine, but I at least want my old computer back. As it is now, I can't do anything on it besides restart it.
    If I could just get to Finder, I could save some files and just reformat it - if the hard disk can be repaired.  Even if it can't, I just need my documents.  Here is the Installer Log:

    Thank you for any help you can give me.

    You are never going to have the option to repair a disk if you are booted from the same disk.
    I think the place to start is boot off your Snow Leopard DVD install disk by holding down the C key on boot up.
    Under Utilities drop down menu  you will have access to Disk Utility.
    From  here you will have the option to repair Disk (ie not grayed out.)
    option: Either insert and wait for the Mac OS X Install DVD window and double-click the Install icon;  or power down, then start up while holding down the "C" key.  Either way, that takes a few minutes.

  • I have a older MacBook I upgraded memory two 3 gb from its original two but it still will not let me update from snow leopard to maverick I have plenty of available ram does anyone know why

    I believe it is running an older version of maverick it is 10.6.8 but it will not let me update any further . I added 3gb of ram to upgrade from the original 2gb it came with but still no updates are being allowed Does anyone have any idea why this is ? I am sure the criteria for the upgrade is available so I don't know why I can not up date it?

    10.6.8 is Snow Leopard.
    Run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8, or download the combo update from here:
    http://support.apple.com/kb/DL1399
    Check via Software Update whether any further updates are required, particularly to iTunes (you will need the latest version in order to synch with mobile devices).
    You should now see the App Store icon in iTunes, and you now need to set up your account:
    http://support.apple.com/kb/HT4479
    You can now upgrade to Mavericks OS 10.9 for free IF you have one of the following Macs, with not less than 2GB of RAM, and at least 8GB of available space on your hard drive:
    iMac (Mid-2007 or later)
    MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
    MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)
    MacBook Air (Late 2008 or later)
    Mac Mini (Early 2009 or later)
    Mac Pro (Early 2008 or later)
    Xserve (Early 2009)
    iCloud system requirements:
    http://support.apple.com/kb/ht4759
    If you cannot run Mavericks you can purchase the code to use to download Lion from the App Store (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard):
    http://store.apple.com/us/product/D6106Z/A/os-x-lion
    or Mountain Lion:
    http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion

  • Drawbacks to upgrading from Snow Leopard to Maverick

    I have a 2008 IiMac running 10.6.8 (Snow Leopard).  I have 4 GB of Ram.  I recently bought the machine used from a friend, had it wiped and the OS reloaded by an authorized Mac store.
    This is my very first Mac and I am a Plumber, not an IT guy, so please excuse my blatant ignorance.
    I have no added software yet, but I would like to add Keynote and some better video and audio software than iMovie and Garageband.  I really bought teh machine for video and audio.
    My questions are: 
    1-Will I experience a noticable drop in performance due to the demands of Maverick?
    2- What other drawbacks might there be to me upgrading to Maverick?
    Thanks for your advice.

    Since it is an older machine with a (comparatively) slower processor, any video work will be slower and that has nothing to do with Snow Leopard vs. Mavericks. For video editing/rendering/burning, the fastest, bestest processor as well as lots of RAM will speed things up. I had a 2006 iMac and it did my video work ok - I just got used to walking away and not using it while it was rendering or processing. I now have a top of the line 2010 and lots more RAM - video work is much faster, but it still takes time - that is the nature of the beast so to speak.
    As for SL vs. Mavericks: if you don't need the bells and whistles of the latest OS including iCloud integration, etc., Snow Leopard will be fine. 4 GB RAM are great for SL; for Mavericks, it is considered the minimum (8 - 12 or more would be better for video work). The latest iMovie version 10  appears to be less user editable and more for fast processing and cloud integration - lots of choices to send to Youtube, Facebook, etc, etc, but not enough options to export so the movie can be burned to a DVD or imported into Final Cut or iDVD. I've tried it twice and will do so again, but will stick with the older version for now.
