Where can I download just Lion 10.7X. Computer not compatible with mountain Lion but still need to upgrade.

Note: I'm on Snow Lepard... I Just tried upgrading to Mountain Lion but it states that it's uncompadable with my computer. So I want to upgrade to just Lion )SX 10.7 YET i can not find anywhere to buy this. It's not in the app store. I can't find any link to older versions of the OS. Can someone please help?

UPDATE: I am going on day 3 and have yet to receive my code! Seriosuly... a NUMBER that they send via email. DAY 3??? Because it take this long to "process"??? You have got to be "F'ING" Kindding me! Customer service is key and Apple USE...USE!.. to be king. I actually waited on the phone for 25 minute just to be told I had to wait for GOD KNOWS WHEN (ie. maybe 3 days) for the order to be processed.

HT201364 why is my computer not compatible with OS X Mountain Lion

I Have a MAC Pro late 2007 with 13GB Memory & 2TB I purchased OS X Mountain Lion as an upgrade to Lion, now I'm told the this is not compatible, why?

Hardware is the reason you can't upgrade. Older CPUs and other parts and pieces can't handle the load.
Upgrade to Mountain Lion/Mavericks.
Check that your computer is compatible with Mountain Lion/Mavericks.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
Mac Pro (Early 2008 or newer) 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 - 4 GB minimum seems to be the consensus)
8 GB or more of available space
If your computer isn’t compatible, you might be able to upgrade to Lion. Based on my experience, I recommend staying with Snow Leopard. You could partition your hard drive and 'test drive' Lion.
Computer Compatibility - Lion                       Lion
Check to make sure your applications are compatible. PowerPC applications are no longer supported beyond 10.7.

How can I find Lion to download it to my Mac Boook/ It is the white plastic model and is now running Snow Leopard. It has 4 GB of Ram but this computer is not compatible with MOuntain Lion. I cannot find Lion anywhere.

How can I find Lion to download it to my Mac Book? It has Snow Leopard and 4GB RAM but it the white plastic model and is not compatible with Mountain Lion. I have been told by the Genius Bar that it will handle Lion.

That underpowered model is better left on 10.6.8 for performance reasons, also the fact that it's dated and 10.7 will likely require you to buy alll new software to replace the PPC based software your currently using.
If you insist, then call Apple via phone and they will sell you 10.7 Lion and provide a link to download it.
My 2¢ is to save up for a new machine, as that one is about to kick the bucket, they only last about 4.5 years or so depending upon use/enviroment.
If your having problems with 10.6.8, perhaps some of the links here can assist, 10.6 is faster than 10.7 in fresh install tests.

Hello royalaqua,
I do think you should ask yourself if upgrading to Lion is the right course to take.
Snow Leopard is an excellent OS and Lion has literally been frozen out after barely a year. Remember too that some of your apps may not work with Lion (those that have Rosetta, for example) so that could mean more new purchases. Plus you may need to uprate your RAM too.

Why is my iMac (G5) not compatible with mountain lion?

Why is my iMac (G5) not compatible with mountain lion? I have 4 GB ram (667) and around 90GB hard drive space.

iMac G5 can only be upgraded to 10.5.8.
If you have continuing use, you are among the lucky ones. I purchased many of these used from a company that shut down its American office. Many of these eventually suffered from the "bad capacitor" problem and required a motherboard replacement from Apple. I was lucky in that my local Genius bar approved these for no charge, even though Apple's extended warranty had expired.
My last one was my desktop Mac. It's power supply failed in 2010 and I paid for a replacement. In Summer 2011 when its HD failed, I decided it was time to move on and purchaed a Mac Mini, which I continue to run on Lion.

Express 802.11n model A1264 not compatible with Mountain Lion?

I have an airport Express 802.11n model A1264. I have been using it with Mountain Lion for a couple of months. Some problems but it worked. Last nite it stopped. - flashing orange light. I am using Airport Utility version 6.1. The helpful? lady at apple support said that model of Airport Express (Gen 1 ) was not compatable with Mountain Lion and I need to get a Generation 2 Airport Express. Is there any other solution?

Hardware failure is a possibility but your Express is most certainly compatible with your version of Mac OS X.

... I had pushed in the reset button on the AU Express -
To properly reset it to factory defaults requires that you depress its reset button continuously for about five seconds - long enough for the LED to flash rapidly, then release it.
After this the Express will create an open wireless network called "Apple Network nnnnnn" where nnnnnn = a set of characters unique to your Express.
Connect to that network by selecting it in the menu.
Launch AirPort Utility. It should find the Express.
If you are still having trouble unplug the Express and plug in to an electrical outlet near your iMac. Not only does this make it easier to perform another "hard reset" should you need to, it minimizes the potential for wireless interference to prevent communication. There is no need to have it connected to your modem as you configure it.
Only after doing all this should you begin to suspect the Express has simply failed. In that case bring it back to Apple for a final determination.
Don't let them tell you it is not compatible with Mountain Lion because I use the exact same one all the time. Even its preceding model is compatible.

Why does snaps pro not work with mountain lion?

I spent a lot money purchasing the pro addition only to be told that it won't work with mountain lion due to Apple's written something into the code that does not permit me to make videos with it. I even tried ot make a video of Indesign acting up so i could send it to Adobe support and it wouldn't allow me to. Is this the resaon it suddenly doesn't work anymore? Are there plans to fix mountian lion to allow me to use my software? Alternatively,, does Apple have something that does screen captures of videos?

this is the repsonse form Ambrosia: (Not sure I understand it)
As far as Snapz Pro X 2 functionality, some major backend Digital Rights Management changes enacted by Apple may be what is preventing you from recording movies you were previously able to record using our software. Basically, our program can no longer access videos before the DRM protections are enabled, unfortunately we have no control over these changes. Please see the following FAQ:http://www.ambrosiasw.com/support/faqs/products/snapz-pro-x /Why-does-the-content-of-my-capture-display-as-a-checkerboard
BTW I am current on the latgest version.
Does anybody know how to work around my problem? I need to be able to record videos on my computer.

Why is my macbook air not compatible with mountain lion?

When i want to buy montain lion in the app store i get the message that my machine (Macbook air) is not compatible. Why is that and can i do something to solve that problem?

Because your model is old and does not support the 64-bit EFI ROM requirement to install Mountain Lion. If you meet the 2 GB RAM requirements you could install Lion:
Upgrading to Snow Leopard, 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. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
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
       5. Some features require an Apple ID; terms apply.
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)
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
         3. MacBook Pro (Mid/Late 2007 or newer)
         4. MacBook Air (Late 2008 or newer)
         5. Mac mini (Early 2009 or newer)
         6. Mac Pro (Early 2008 or newer)
         7. Xserve (Early 2009)
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
     Am I eligible for the free upgrade?
         See Apple - Free OS X Mountain Lion upgrade Program.
     For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.

HT4814 Server App not compatible with Mountain Lion

I have just upgraded my station to Mountain Lion and previously copied SERVER App is not compatible. I am not going to upgrade my server to Mountain Lion as yet, therefore I cannot administer my server through 2. from above. Sollutions?
Station: ML on MacMini. Server MacMiniServer Lion Server

Right, yes I understood your plan. The worry I have is that even once you copy Server v2 to your workstation, on first launch it will try to install the ML Server components. So....I fired up my virtual machine of ML client to see once again what's that like again. One first launch Server prompts to configure/install the server software. However the menu and menu items are live, e.g. the "Manage" entry is live. So I suspect you could connect from the workstation to the server and manage it. I just don't know if that "setup" screen will thereby go away, if I'm only using it to manage the server from the workstation. I'm away from my Server, so I cannot at the moment verify what happens.
I went ahead and bought ML + Server v2. I installed it in a VM to take a look at the changes and to see if services I use functioned o.k. in testing. I took forever to setup my MacMini with Lion Server because I was new to OS X Server, but I've been using Macs for ages and OS X from the very start. So I installed, messed up, reinstalled Lion Server many times before I figured it out. Right when it was pretty much good to go, ML came out. Since my MacMini with Lion Server never got used for anything more than testing, it was a big deal for me to go ahead with ML + Server v2. I'm just using it as a home server, and pretty limited at that: OD, File Sharing, Network Homes, and Profile Manager. ML gives me one share and an easy way to turn on FTP (compared to Lion), so I'm going to use that service too; I have a scanner than doesn't work with Lion and ML's SMB but functions with FTP.
Some things are missing in ML, DCHP for instance is but isn't there. You might take a look at to get an idea:
http://arstechnica.com/apple/2012/07/the-server-simplified-a-power-users-guide-t o-os-x-server/
I always take caution with early releases, I usually test clones made with SuperDuper! or Carbon Copy Cloner. With Mt Lion Server, it was easier, again since I didn't have a "live" Lion server, to make a virtual machines.

Apgoee Duet not compatible with Mountain Lion?

When trying to run Logic after having downloaded Mountain Lion it says that Apogee Duet isn't compatible with it!
Is anyone expierencing the same problems?
If so, is there a way to remove mountain lion again?

Hi Stefaan,
I was wondering the same thing. This is from the Apogee website:
"All current Apogee products are fully supported with Mac OS X Mountain Lion (10.8). For a full list of compatible products and more info, please see the Apogee Compatibility chart"
You can check out their product compatability chart at:

Hope this helps.
