I have a macbook air 2,1, can i upgrade this to lion

I have a macbookair 2,1 and I'd like to know if i can upgrade this to lion or not?

Lion or Mountain Lion?
You should be able to. This is for Mountain Lion. Lion link below.
iMac (Mid 2007 or newer) model number 7,1 or higher
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
MacBook Air (Late 2008 or newer) model number 2,1 or higher
Mac mini (Early 2009 or newer) model number 3,1 or higher
Mac Pro (Early 2008 or newer) model number 3,1 or higher
Xserve (Early 2009) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported.       
Application Compatibility
You can also check by going to the  menu, select About this Mac, click on More info…, then click System Report and select Software/Applications.
If you have applications that you want to use that aren’t compatible, you can retain Snow Leopard and create a new partition to install Mountain Lion on or you can run Snow Leopard  server in a virtual mode.
If your computer isn't compatible, you might be able to upgrade to Lion.      
Computer Compatibility - Lion
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again.  You can make a bootable DVD/USB stick to install using this free program.

    Great tip Stephen!!
    I was so frustated from this issue that I used to use Windows iTunes for mass editing info, adding Lyrics etc and then transfering songs to Mac. This tip has alleviated my pain!!
    Thanks for the tip. This question should be tagged as answered.

    Whatever you read was incorrect. You can upgrade directly to Mavericks. It is in the App Store and is free.
    Snow Leopard predates the operating system you already have. That's the reason it will not install on your MacBook Air. You spent $20 needlessly for it, but it's yours to resell if you wish.

  • I have a macbook air.. Can someone hack my keychain access through an email download attachment link?

    I own a Macbook air.. I have just recently went into my gmail account and opened an email from a person that was interested in buying an item that I was selling from craigslist. The email sounded legit, not like a scam.. I usually can spot those out. So then I happen to notice an attachment download link at the bottom, like it was a picture or something. So I opened it, and all of a sudden this "set of keys icon" popped up and starting showing all of my passwords, and certficates, and files from my computer... i went and googled what the keys meant, and it is my computer keychain access.. Which stores and backs up all of my login in passwords and informtion, and administrative options for the computer.. What I am wondering is why would this have opened up as soon as I opened a random email? Am I being hacked for all of my login information, and passwords? Can he access all of what this "Keychain access" is showing me? I am kind of scared and nervous now, because I have never since I have owned this laptop, seen this kind of thing before, expecially opening it up in an email. Please someone, can you give me answers to my concerns. Thank You. Julia.

    That was an S/MIME cryptographic signature. The Keychain Access application opened so you could add the sender's public key to your keychain. It's not hacking.

  • Hi, i have a macbook air, but i want to upgrade to the new model. I want to sell my existing air, but can i wipe the memory clean of all existing content to sell it, but still update my new pc when it arrives?

    Hi, i have an Air but want to upgrade to the new model. How do i wipe the memory clean of my existing Air so i can sell it, and ensure when i get my new PC it automatically assumes the existing settings? Any help appreciated...

    First of all, as a rule you should have two backups before you do anything else. (most don't, and it's up to you).
    I would have one backup done as a Time Machine backup on an external disk, which you will use to import all settings, data and apps to your new MBA via Setup Assistant on your very first boot of the new machine.
    Second, I would have prepared, a bootable backup done via Carbon Copy Cloner or Super Duper on a second external disk. This you can use for unforseen problems that might be evident on the Time Machine backup (hey it happens).
    After you have these two items in preparation, then use the original system disk or flash drive to reformat and reinstall the original operating system to the old machine, cleanly. After that, it is ready for sale. If the unit is not an SSD equipped MBA, you can perform a secure wiping of the disk when you perform the reformatting.
    To reiterate.... You need a good Time Machine Backup as a source for you setting up the new Mac with Setup Assistant.

  • Deleted emails keep returning to my inbox on my new macbook air! How can I stop this?

    I recently upgraded from a Macbook to a Macbook Air and now some emails that I delete return to my inbox almost immediately. I've never experienced this issue before and it's kind of frustrating. How can I fix this?

    Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore is not, in itself, a solution.
    First, empty the Trash, if possible.
    Triple-click anywhere in the line below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
    find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 \) 2>&- | wc -l | pbcopy
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window by pressing command-V. The command may take a noticeable amount of time to run.
    Wait for a new line ending in a dollar sign ($) to appear.
    The output of the command will be a number. It's automatically copied to the Clipboard. Please paste it into a reply.
    The Terminal window doesn't show the output. Please don't copy anything from there.

  • I have a Mac mini 3.1, can I upgrade to mountain lion ?

    hi, can I upgrade my Mac mini 3.1 to run OSS mountain lion ?

    Yes, you can upgrade to 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

    Thanks very much for the reply.  I sent a message via the link you pointed out and it came back with "no refund on this product"  I guess my lack of knowledge has cost me here which is a bit sad.  I shall keep trying but guess I will need to buy the product again.  I wonder who benefits from this?  Not me ;-(  But thanks anyway, if anyone has had this issue and found a way out i would love to know....

  • I have logic express 9.1.7, can i upgrade to logic pro

    I have Logoc Express 9.1.7, can I upgrade this to the latest Logic Pro app? If not, will all my plug ins, instruments etc work if I am forced to purchase the new app?

    I think you'll be able to run okay in the new version. The other features you'll get are: Better mastering tools, a new synthesizer (sculpture) and the Space designer reverb. I think they are all
    Best wishes

    sorry to drag this on, your answers were great i kinda forgot to clicked the "this solved my question" thing.. but is there a limit on the number of computers i can download it for free to?
    Not to muddy the waters but according to the license agreement here: http://images.apple.com/legal/sla/docs/OSX108.pdf, Apple distinguishes between a "Preinstalled and Single-Copy Apple Software License" and a "Mac App Store License." The Preinstalled license limits use of the installer to one copy on one Apple-branded computer. The Mac App Store License allows the installation of "one (1) copy of the Apple Software directly on each Apple-branded computer running OS X Lion or OS X Snow Leopard (“Mac Computer”) that you own or control." Since in either case, the free upgrade is going to be coming from the Mac App Store it would seem that the Mac App Store License applies. But since the intent of the free upgrade is to serve as an inducement to buy a computer with a soon to be replaced OS by offering a free upgrade of the OS preinstalled on the purchased computer, perhaps it is covered by the Preinstalled wording. The Terms and Conditions of the upgrade program are unclear on that but maybe it becomes a matter of how the content code that's issued works. If the content code can be used more than once with your Mac App Store account or if the Mountain Lion installer appears as available for installation when you log into your Mac App Store account on a Mac different from the one that qualified you for the upgrade, then it would seem that the Mac App Store License is what applies here. Of course I'm no lawyer; if I was, I'm sure it would be even more complicated.

  • Can I upgrade to Mountain Lion on my MacPro?

    I've upgraded to Mac OS X 10.9.5 on my MacBook Air and assumed I could upgrade to Mountain Lion on my MacPro.
    I don't know where to find its date of birth, which apparently affects compatibility. The Hardware Overview shows:
    Model Identifier: MacPro1.1
    Processor Name: dual-Core Intel Xeon
    Process Speed 3 GHz
    No. of Processors: 2
    No. of Cores: 4
    L2 Cash (per processor) 4MB
    Memory 9GB
    Bus Speed 1.33 GHz
    Boot ROM Version: MP11.005C.B08
    Advice welcome.

    The Apple "company line" is that the Mac Pro 1,1 and 2,1 do not contain the 64-bit firmware needed to support booting the 64-bit only kernel used in 10.8 and beyond.
    The hatter has given you links for advanced users who may wish to make unsupported modifications to their Mac Pros to install and run 10.8 and later  unsupported.
    Unless you are a developer, or think like one, you may be better served by getting a more modern Mac Pro (not necessarily the latest and greatest, just a newer one). The 2009 model and later offer substantial architecture changes that make them quite a bit faster than previous models, even with the same number of processors.

  • I have a macbook air bought in 2010 wit liquid damage that might has affected the SSD card. I need to get my data but apple won't help. Authorized dealers never seem to have the same model to try whether the SSD card works. How can I get my data quickly?

    Hi
    I have a macbook air bought in 2010. It has liquid damage that might or might not affected the SSD card. I need the data on my SSD card for work and I need it urgently. Apparently Apple won't get the data out, even if I have apple care... Licensed apple dealers need to have the same macbook air model so they can insert the SSD card and check whether the data is there, and they never seem to have one...
    I'm really disappointed with apple. It's been two weeks and I haven't been able to find out whether the SSD card is holding my data. It can't take that long to do it in store... How can they sell a product and then wash their hands on the matter?
    Anyway, enough with the apple rant. I need to get this data urgently so I need to find out how I can get it out of the card. The SSD card and data might be fine so I don't want to take it to a data recovery centre and get charged loads.
    Thanks for your help.
