absolutely  ok to run LIon.
Double of the needed Ram you have already and CPU is what Lion needs.
MacAppstore will also tell you if your machine is not supported, prior to purchase.. it tries to block you from purchasing it, if so.

    I have updated from Snow Leopard to Lion with Safari Version 5.0.5. Now I can not update to Safari 5.1. There is no update in the Software Updater, and on the apple-download page, I only found a Safari 5.1 for Snow Leopard. When executing it, there is an error message, that it is for 10.6 only.
    It seems that I should have first updated Safari, and then only to Lion, which I didn't. Any idea how I can fix this now without having to rollback to Snow Leopard, update Safari and then go back to Lion?

    Try this Safari5.1 from the installer package

    The download worked better with Firefox not sure why. At the bottom of the page after the captcha>> slow down load is the Free link,  it took about 4 minutes to download on my test.

  • Will I need to buy Lion on a Lion preinstalled macbook air after transferring a snow leopard system from an old macbook pro

    So will I need to buy Lion from the app store to upgrade, after I transfer my old snow leopard system to a new macbook air, that came with Lion?
    Thanks!

    Use Setup Assistant when your new Mac first starts up to transfer your stuff from the old Mac or it's backups.
    If it comes with Lion, see Using Setup Assistant on Lion
    If it comes with Snow Leopard, see the slightly-different Using Setup Assistant on Snow Leopard or Leopard, then upgrade to Lion.

  • Is Snow Leopard now pre-installed onto MacBook Pros?

    I'm going to buy a MacBook Pro, but I'm wondering about the installation of Lion. If I buy a MacBook Pro now, will I have to download Snow Leopard AND Lion?

    It will only have Snow Leopard installed. But you will be able to get Lion for free when it is released. See:
    The Mac OS X Lion Up-To-Date upgrade is available at no additional charge via the Mac App Store to all customers who purchased a qualifying new Mac system from Apple or an Apple Authorized Reseller on or after June 6, 2011. Users must request their Up-To-Date upgrade within 30 days of purchase of their Mac computer. Customers who purchase a qualifying Mac between June 6, 2011 and the date when Lion is available in the Mac App Store will have 30 days from Lion’s official release date to make a request.

  • Problem with Snow Leopard and LED Cinema Display + MacBook pro

    I just upgraded to Snow Leopard. When I work on my MacBook Pro everything works fine. But when I use through the LED Cinema Display then the machine hangs on several programs, like iTunes, Time Machine, even Finder. Before the upgrade everything worked fine. Anyone having the same problem?

    I've had similar problems when using my cinema display. I am currently using it with my usb backup drive disconnected and , so far, have not had the problems. Here's hoping, although it is not a good permanent solution, it means I do not have Time Machine running or access to my other backup files. I suspect that it may be a problem (as reported by others on this forum) with SL mounting a sleeping drive. Time will tell.

  • How to downgrade from OSX 10.8.5 to Snow Leopard, on an Early 2011 MacBook Pro, without the original installer disk?

    Hello! So here are the specs.
    I have an Early 2011 MacBook Pro, which came with OSX 10.6.6 by default.
    I've lost my installer disk so I though I'd buy a retail one from the online Apple Store, and version 10.6.3 is what they sent me.
    Simply running the install OSX app won't work, I get a msg saying:
    -- You can't use this version of the application "Install Mac OS X" with this version of OS X. You have "Install Mac OS X" 23.1.1. --
    So, I've tried booting from the new disk hoping to erase my current drive and install Snow Leopard, but no can do, I get 3 beeps and have to force shutdown (not RAM related, see below). Laptop works fine when I spare it this maneuver.
    After some research I understand 2 things:
    1. Only the original installer disk will let me restore factory settings (and I don't have it).
    2. I can only install the default OSX (10.6.6) or a later version (that 10.6.3 DVD may not have the correct drivers for my system).
    Are these conclusions right? If so, would the Apple Store replace my disk for an updated 10.6.6. one? If not, then what are my options?
    Thank you!

  • HT201250 I use Snow Leopard and tried restore my Macbook pro using Time Machine.

    After waiting a considerable time for Time Machine to restore my whole system, applications and files I had problems in that my Macbook Pro would not restart. The Apple logo appeared but then the screen scrolled down and a lot of letters, numbers and symbols appeared - not making any sense, and a box appeared telling me to restart holding down the on button. This I did. However it kept on repeating. In the end I had to reinstall the whole lot. Fortunately I had backed up all my files. I cannot use some of the programs I have because I cannot retrieve them. I do not have a disk with them on to reload because I downloaded them from the net and they are old progs and still did what I wanted. A lot of files I have saved do not open now without the old system and apps.Can anyone come up with an idea?

    Ah that's good to hear, does this still work if TimeMachine updates to reflect the 10.7 drive?
    There is no special update.  After installing Lion, Time Machine will do a normal "incremental" backup, of the stuff that's new or changed.  That will be relatively large and lengthy, of course, since OSX and the default Apple apps will all be backed-up.
    But there's nothing else different about the TM drive. It stil contains all the past backups, including older versions of OSX.
    In other words if a user upgrades to 10.7 and doesn't like it after a few days/weeks, has TM connected and it updated to relfect 10.7, can the user c boot off the 10.6 disk erase and restore 10.6 from the TM drive?
    Yes, except you don't have to erase. 
    You just boot from the Snow Leopard Install disc and do a full system restore.  That includes erasing the destination, so it doesn't matter what's on it.  Then everything on the backup is restored, including OSX, apps, users, data, settings, etc., just as it was at the time of the backup selected.
    See Time Machine - Frequently Asked Question #14, especially step (g).  The sample is a bit fuzzy -- it's a photo, since you can't screenprint there, but note that the last two backups were made on Snow Leopard:
    Once that's done, and the system restarts, you can use the "Star Wars" display to restore selected items from later (ie, Lion) backups, but of course in some cases (Mail for one), the Snow Leopard apps won't work with the Lion-formatted files.

  • Cannot Install Snow Leopard 10.6 disc on Macbook Pro (will not boot disc)

    Hi there,
    I have a MacBook Pro 2.4 GHz Intel Core 2 Duo with 4GB of DDR2 SDRAM. It is currently running Mac osX 10.4.11.
    I am trying to install a snow leopard disc 10.6 but when I click on the disc and hit install, it restarts the computer and tries to start it up with the install disc. This is where I get an apple logo with a spinning progress wheel that doesn't go away until I force the laptop to power down.
    Can anyone tell me how I can resolve this issue?
    Thank,
    Caleb

    Double check to make sure your computer meets all the qualifications for the Snow Leopard upgrade. Especially check out the "Upgrading from Mac OS X v10.4 Tiger" section in the right column - http://www.apple.com/macosx/specs.html
    Your disc may be damaged. You can always take your computer and the disc back to the Apple Store. See if they can boot.

  • Can i install OS X Snow Leopard on my Early 2011 MacBook Pro 13' ?

    Hi guys , just wondering can i install on my Early 2011 MacBook Pro 13'' OS X Snow Leopard ? i dont like Lion at all .   Many Thanks .

    You may be able to install SL 10.6.8 (assuming there was no firmware update) if you follow these directions. Check with MacTracker http://mactracker.ca/ and download their free app detailing more info you ever thought you needed to know about Apple products.
    - you can re partition partition the mac drive so that  you can retain the pre-installed lion install
    - or use an external drive
    - attach your computer via firewire 800 to a Mac computer (capable of running 10.6.8 )
    - boot the your computer holding down the T key to get it into target disk mode, it will appear on desktop as an external drive.
    - install SLS v 10.6.3  Retail version from the DVD onto the new partition or external drive where you want Sl installed.
    - install the 10.6.8 combo update.

  • Should i upgrade from Snow Leopard to Lion on my Macbook Air1,1 ?

    Hi,  I just found out the Macbook Air i bought from my friend recently isn't compatible to upgrade to Mountain Lion.
    I'm very dissapointed, but thought i would upgrade to OS X Lion instead, so at least i would be able to use iCloud.
    Two problems:
    This is my first Mac, i know very little about them; i have no idea if an upgrade could make my Mac slower or cause other problems.
    And I can't find OS X Lion in the App Store.
    I verified my disk (found no problems) and have back-ups using Time Machine.
    I'm running Snow Leopard 10.6.8
    Model Name:          MacBook Air

    You can install it if you want. If you see that the system is unstable, press Command and R keys when your Mac starts, open Disk Utility, erase the disk and install OS X. See if your applications are supported > http://www.roaringapps.com

    DO NOT use Tech Tool Pro on your Intel Mac. It is only a PPC version. TTP has not released an Intel version yet.
    TechTool Pro hasn't been, but the Intel version of TechTool Deluxe was released sometime in the last few days. I couldn't say if that's the version Nancy is using, of course, but it is finally available for download (with instructions to create a bootable CD) for those who have enrolled an AppleCare Protection Plan.
