Lion won't operate my app and snow leopard came with my MacBook Pro

I installed Lion without checking to see if it supported my "can't do without" app.  Now I'm in a panic.  One remedy is to reinstall Snow Leopard, but it came with my new laptop and I don't have any disks.  Is there a solution to that problem?  Is Lion just out of the question, never to be used?  Help! 
Thanks to all.

Your new computer came with Snow Leopard installer discs. If you've lost them you can purchase replacements at Apple Store Customer Service at 1-800-676-2775. Or you can purchase a copy of Snow Leopard at any Apple Store for $29.00.
To reinstall Snow Leopard you will have to first erase the hard drive. I hope that you have backups of your files. If not then be sure to make one before reinstalling Snow Leopard.

  • Running Lion and Snow Leopard on the same MacBook Pro

    So here's the thing .....apparently Lion won't run Photoshop and Illustrator CS2 (which I'm quite happy with and not about to shell out silly amounts of money to Adobe for even CS3) and apparently there may be (and I stress may be) problems with Word 2008 (likewise money to Microsoft for Word 2011).
    I think, and probably won't know till I've installed it, that I'd like to try Lion on my Macbook Pro but keep Snow Leopard as a separate OS to run Photoshop, Illustrator and if necessary Word until I can afford to pay Adobe (& possibly Microsoft though I can't really see what improvements they can make to Word 2008) the large amounts of money they seem to think they deserve for an upgrade.
    Does anybody out there know if it is possible to run both Lion and Snow Leopard on the same machine and if it is how do I do it?
    Thanks for taking the time to read this.

  • Can I run Tiger and Snow leopard on a new macbook pro 15"

    I have a Macbook running Tiger, soon to be replaced (I hope) by a
    15" Macbook Pro Sno Leopard. Can I partition the drive on the MBP to run
    Tiger also, as I have Adobe Creative Suite 2 and can't afford to upgrade that too. And I really don't want to run to computers.

    Welcome to Apple Discussions!
    Snow Leopard will run CS2 with some limitations.
    Either find a Mac older than October 26, 2007 you can use until you can bring all your software to Snow Leopard compatibility from these sites*:
    Or find an alternative application for the functions you need from the first link that is Snow Leopard compatible if you can use that.

    The Early 2008 MacBook can only go up to Lion...the compatibility requirements for Mountain Lion and Mavericks are the same which says Late 2008 MacBook.

    I replaced my hard drive and lost iPhoto. Is there a way to retrieve?  I can not find the starter discs that came with my Macbook Pro.

    Customer Service: Contacting Apple for support and service - this includes international calling numbers. You can purchase replacement discs from Apple.
    Or, you can upgrade to Lion or Mountain Lion:
    Upgrading from Snow Leopard to Lion or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99.
    If you sign into the App Store and try to purchase Mountain Lion but the App Store says your computer is not compatible then you may still be able to upgrade to Lion per the following information.
    A. Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
             7. Xserve (Early 2009) - Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.

             See App Compatibility Table - RoaringApps.
         For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.
    B. Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space

  • 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.
    that's a step by step walkthrough.

  • How can I install Mountain Lion in a VMware fusion, if it came with my macbook pro, and not purchased through the app store?

    I have Mountain Lion on my Macbook Pro with Retina but I want to install Mountain Lion in a VM for application testing. I try to install it from the recovery partition but it states that when I put in my apple ID, it states that it was not purchased through the App Store. My OS came with my Macbook. Is there anything that I can do to get it to install in a VM?

    Not really. The license that comes with pre-installed OS is only for that Mac.
    A. Preinstalled and Single-Copy Apple Software License. Subject to the terms and conditions of this License, unless you obtained the Apple Software from the Mac App Store or under a volume license, maintenance or other written agreement from Apple, you are granted a limited, non- exclusive license to install, use and run one (1) copy of the Apple Software on a single Apple- branded computer at any one time.

  • Can i install snow leopard on my new macbook pro

    I'm looking at a new laptop but I understand Adobe CS4 won't work on Lion, so I'd rather install Snow Leopard on the new macbook. Is this possible?

    Difficult, and even reported "success" is likely not consistent enough for your *need* for Adobe CS4.
    You can try for a unit off the refurbished list ( > Store, bottom of the left hand margin is the link).  Units from pre-July and last year can be found, and come with warranties just like brand new.

  • Snow Leopard on new 2011 MacBook Pro?

    I need to buy a new MacBook pro, as my early 2008 model just died on a road gig (4 months out of warranty) but most of my drafting software has been found to be incompatible with lion, is it possible/simple to put snow leopard on a brand new MBP 15"?

    Yes. You can create a second partition on which to install a copy of Snow Leopard.
    To resize the drive do the following:
    1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
    2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.

  • Snow Leopard 10.6 on MacBook Pro 2,1

    As the title suggests, I'm trying to install 10.6 on my MacBook Pro 2,1. I am getting into iPhone dev with a few of my colleagues, and one of the requirements is 10.6. However, when I previously tried installing the OS it told me it could not be installed on my computer due to my 32-bit EFI or something like that. I have read numerous accounts of people running Snow Leopard successfully on their MacBooks, an I am wondering what I am doing wrong.

  • Upgrading to Snow Leopard & replacing battery on MacBook Pro 06

    So I have a MacBook Pro, running Tiger, that I bought in November 2006. I have about 500$ to spend. I want to upgrade to Snow Leopard and the most recent version of iLife. I also need to replace the battery since it's dead (only lasts 20 minutes unplugged...).
    Any suggestions on what I should buy exactly and how to proceed with the installation (meaning what to install first, and if I should format my computer before doing so)? Thank you!!

    Purchase a new battery
    Disconnect all peripherals from your computer. Boot from your install disc & run _*Repair Disk*_ from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
    Select your language.
    Once on the desktop, select Utility in the menu bar.
    Select *Disk Utility.*
    Select the disk or volume in the list of disks and volumes, and then click *First Aid.*
    Click _*Repair Disk.*_
    Restart your computer when done.
    Repair permissions after you reach the desktop-
    *Upgrading from Mac OS X v10.4 Tiger.*
    +If your Intel-based Mac is running Mac OS X v10.4 Tiger, purchase the Mac Box Set, which is a single, affordable package that includes Mac OS X v10.6.3 Snow Leopard; iLife, with the latest versions of iPhoto, iMovie, GarageBand, iWeb, and iDVD; and iWork, Apple’s productivity suite for home and office including Pages, Numbers, and Keynote.+

  • Mail app and Snow Leopard, Mountain Lion and Mavericks

    I have, and use, 3 different Macs, an older MacMini running Snow Leopard, an older MacBook Pro running Mountain Lion and a new MacBook Pro running Mavericks.  My personal email account, setup using the, works fine on Snow Leopard and Mountain Lion.  On the MBP running Mavericks, I setup the using the same settings as on Snow Leopard and Mountain Lion.  It doesn't work.  Nothing but timeouts.
    I've read a lot about the problems with Mavericks and IMAP and updated Mavericks apps, including Mail.  Still no go.  I'm not so much asking for help as registering that the IMAP problems aren't fixed.
    But if anyone has some ideas, I'm listening.
    Thanks all!

    I'd check to see if the latest version of the plug-ins are Snow Leopard compatible or not, unless you have a really large number of plug-ins to deal with, where you could just see what's broke and what's not, post upgrade. But beware of retaining the old ones. For example, 10.6 Mail broke the GPG-Mail plug-in that works under 10.5.x. Search the Snow Leopard Mail forum using the search phrase "GPG Mail" OR GPGMail OR "GPG-Mail" or other mail plug-in names of interest to you.

  • Virtual Desktop Apps and Snow Leopard Upgrade

    I'm currently running most recent version of Parallels Desktop and I'm concerned that when I upgrade to Snow Leopard I will lose the use of PD until Parallels' updates their software. Unfortunately, I need to use Windows OS for school! Not much on Parallels' website yet.
    I'm just wondering if I should wait to upgrade until parallels folks catch up?

    According to
    Parallels Desktop 4:
    Parallels Desktop 4.0 is compatible with Snow Leopard and can be installed on Snow Leopard Host, please make sure you are using the latest available build 3844. You might, however, experience some minor issues. We will release fully compatible Parallels Desktop 4 build to be installed on Snow Leopard soon.
    We have following know issues with PD4 build 3844 and Mac OS X Snow Leopard:
    1. Host Snow Leopard.
    - QuickLook plugin crashes when trying to do preview on PVM bundle (crash invisible for user)
    - Updater download but fail to install PD4 updates (workaround – close autoupdater and run installer manually)
    - Mounter/Explorer fail to open PD4 disk images
    - iPhone client fail to connect
    - Taking snapshots very slow on host Snow Leopard
    - Opening a web link from Windows in Mac Safari using Shared Internet Applications feature results in appending garbage to the link
    - Snow Leopard 64bit host KP when connecting USB device
    Depending how important windows is to you it might be worth waiting.
