How do I upgrade my OSX Snow Leopard to Lion?

I have Snow Leopard on my MacBook (bought 2009). I have been unable to get it onto Lion as I could not access the app store (software error, now fixed).
I believe I have to from Snow Leopard to Lion to get to Mountain Lion. Thing is I cannot find Lion on the app store, and think it has been taken off.
So how on earth can I get to Lion?
Help please.

If you have Snow Leopard 10.6.8 installed you don't need Lion.
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.

Upgraded from osx snow leopard to lion and still no iCloud

Upgraded from osx snow leopard to lion and still no iCloud settings in System Preferences, why?

I have the exact same issue, and no Profiles for me under System. My system was upgraded from 10.6 as soon as Lion came out and I've never had the icon.
I have had iCloud set up by creating an account within Mail, Contacts & Calendars - but in this setup my Mobile Documents folder, my iCloud "Documents and Data", never synchronized with my other devices. That is why I began wondering why I don't have the iCon as I have seen other Macs that came with 10.7 installed factory.

I don't believe ML will upgrade on top of anything earlier then SL. You might have to do a clean install.

You need to *call* Apple at 1-800-MY-APPLE, as Ralph already said.
But "since one week" sounds like a direct translation of French "il y a". You should call your local country's Apple suuport and ask.

Upgrade to osx snow leopard from 10.4.11

I have heard that upgrading from 10.4.11 to snow leopard can be done, without the purchasing the useless 'box set', but my question is if i upgrade my os will i lose or keep all my programs, applications, documents and- most important- my music ??? also could someone please confirm that all i need to upgrade is the £25 osx snow leopard disk from apple ... cheers now ryan.

Welcome to Apple Discussions, Ryan.
Yes, you are correct about the the £25 upgrade DVD.
No, you should not lose anything. But a good backup is always recommended, I prefer SuperDuper or CarbonCopy Cloner.
EDIT: If you want to check compatibility of your apps...

How can I share files from Snow Leopard to Lion?

I have an iMac running 10.6.8 with file sharing turned on. (I've tried AFP and SMB).
I am trying to connect to the iMac on my LAN using a Macbook Pro with 10.7.5.
I am immediately prompted to authenticate – so I am confident a connection is being made (I am also able to ping) – but when I enter my user credentials from the iMac, I get the spinner (not the beach ball) basically forever. I've let it go for several minutes and nothing ever happens.
This article seems related, but following the procedure in it did not help:

Has anybody been able to file share from Snow Leopard to Lion or Mountain Lion?

The firewall is off on both computers.
How can I werify the shared user is enabled on the iMac with the correct authorization and permission? It does not seem like sharing is configured per user. The user is my normal user account which I use when logged into that machine for everything. I am using those credentials when trying to connect from the Macbook Pro. In the past I did this frequently without trouble. I am not sure when the problem started but the only thing that has changed was I got a newer Macbook Pro last year with Lion.
If you grow weary of this, you might just bring the Macbook Pro over to the iMac and use Target Disk Mode to mount that iMac on your Macbook Pro as a desktop disk. Then drag and drop. No a long term solution.
This is not practical for me as I frquently have need to work from another room using the Macbook Pro and with files that typically live on the iMac (and get backed up from that location). I am making due with Dropbox for now, but the reason I have been driven to post here is that I am looking for the long term solution.
Thanks for feedback. Let me know if you have any additional thoughts.

How do I import mail from Snow Leopard to Lion Mail?

Tried dragging ~/Library/Mail files and folders across.
But Mail insisted on my setting up an accounr (I have several) and put everything into that one account.
Anyone know of a foolproof doc./url or checklist, please, which explains how to get everything that was in Snow Leopard Mail into Lion Mail?
Thanks!

similar "solution" for how to import ical from snow leopard to lion:
1) copy the following files (e.g. from a snow leopard backup) prior to first opening ical:
1a) ~/Library/Keychains/ (folder "Keychains")
1b) ~/Library/Calendars (folders "Calendars")
1c) ~/Library/Preferences/com.apple.iCal.* (ical preferences files, "com.apple.iCal.helper.plist", "com.apple.iCal.plist")
1d) ~/Library/Preferences/iCalExternalSync.plist
2) then open ical in lion ... import/update will follow
if you have opened ical prior to the above steps these files (1b, 1c and 1d ) have already been created, so you have to replace them with your backups from snow leopard described above
if you have set up calendar accounts in system preferences "Mail, Contacts & Calendars" you might have to delete them before applying the above steps
ps:
not quite sure if the following steps are necessary (or did help) for mail/ical import, because mobileme sync works now different in lion (no option for syncing calendars anymore within system preferences—>mobileme) ...
i did a mobileme sync in snow leopard prior to the clean install of lion with:
Calendars
Mail Accounts
Mail rules, Signatures, and Smart Mailboxes

How do you install mac osx snow leopard 10.6.3

when installing on my pc it says i need intel what do i do to install the snow leopard 10.6.3

To clarify, Mac, Macintosh, are names for machines made by Apple Inc, as well as the operating system that will run on those machines.. If you don't see on the machine either the Apple logo, which has the icon of an Apple with a leaf out its top, and a crescent bite taken out of it, or the name MacBook followed by Air, Pro, or nothing it won't install Snow Leopard. iBook, Powerbook, PowerMac are all older models that don't support Snow Leopard. Machines by Compaq, Dell, HP, Toshiba, Gateway do not support any Mac OS. It would help to know what you are running. If you are running a Compaq, Dell, HP, Toshiba, or Gateway, you can get a new Mac Mini for as little as $600, and used or refurbished one for less. If you need help finding a used or refurbished Mac, we can give you resources for what will run Snow Leopard.

Can't upgrade to from Snow Leopard to Lion or Mountain Lion though I have paid for both.

Hi again!
I lost all sound when upgrading to Mountain Lion from Lion and was told by Apple that the cause was likely to be a bad install of ML. I am using a Prism Sound Orpheus Sound Card which worked fine with Lion.
Since then I have put in a new internal System drive and installed the latest version of Snow Leopard firstly with the DVD'S and the using software update.
When going to the apps store I cannot download ML or Lion as I believe (maybe)? that the Apps store thinks that I already have it as it was downloaded into the corrupted system of my old system drive? . I note that all the apps that I have are not listed on the new drive i.e.Pages etc How do I get around this and download Lion and Mountain Lion so that I can rebuild and test my system?

You will need to remove the drive that has Lion/Mountain Lion installed, then boot from the Snow Leopard drive in order to redownload Lion or Mountain Lion. App Store detects any extant Lion/Mountain Lion system thus blocking you from re-downloading.
This time save the download so you won't have to do it again by copying it to your Downloads folder. You can then make your own installer:
Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
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.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.
As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process.

How do I move back to Snow Leopard from Lion if Lion came on the computer?

I have a 27" iMac that came with Lion on it. I want to go back to Snow Leopard so that some of the old software that I liked can be used again. I do not use apps, do not have an iphone or ipad, would never put information in to a Cloud, so Lion aor Mountain Lion are not for me. Is there a way to go back to Snow Leopard and still have the ability to upgrade should I change my mind?

How can I go back to Snow Leopard from lion without loosing files, etc.?

I recently downloaded Mac OS X Lion, but I can't stand it. I've heard you can't get a refund from the app store but I'm not sure how that works and I'd realy like my money back. Also, if I do downgrade, I'm not sure how to back up my files. I have music, documents, and pictures I don't want to lose. I don't have time machine. I have a usb but I'm not sure if it is capable of holding music from itunes? Other than that I'm not sure how else to back up things. I realize I have a lot of questions and I'm not exactly well informed with this stuff so any help would be greatly appreciated (:

Dreamweaver CS4 Crashes on Startup [ OSX Snow Leopard]

I would greatly appreciate any feedback regarding the problem I am finding below.
For some strange reason all of a sudden Dreamweaver crashes everytime I open the application. I have recently upgraded to OSX Snow Leopard but have been using Dreamweaver without any problems since upgrading. I have tried uninstalling the full Adobe CS4 suite and have reinstalled from scratch but this hasn't made any difference. I have also removed the preference files, to no avail. I am not sure if this is a Apple problem or a Adobe application problem. All the other CS4 applications open without a problem.

How do you switch back to snow leopard, lion is crap?

How do tou switch back to snow leopard? Lion is crap, so dissapointed.

Keep the inflamatory comments down or the thread will disappear, as long as your questions are supported related it's fine.
Here's how to go back to Snow.
How can I uninstall OS X Lion and go back to Snow Leopard?
1: Copy your user file folders (Documents, Pictures, Movies, Music, not Library) to a external blank Disk Utility formatted HFS drive (not TimeMachine) and disconnect all drives. Make a note of your username and hard drive name. Write down any essential information like passwords stored in keychains and product serial keys.
2: Stick the 10.6 installer disk into the machine and reboot holding the c key down. Second screen in choose Disk Utility from the Utilities menu.
3: On the left select the hard drive makers name of your internal boot drive (important) then click Erase and Erase... button (if you want to wipe the drive of all lingering data then choose Security Option>Zero all data) when choosing a name for the drive, use the same drive name as before.
4: Quit and install 10.6, then go through setup, reboot and use the same user name as before. Software Update, install programs from fresh sources (enter any serial keys) Hold Option and click on Purchases in AppStore to redownload (not Lion of course) and then finally return user files to their respective folders on the Snow Leopard drive.
5: If you have issues with iPhoto, you can right click on the iPhoto Library and "Show Package contents" and in there is a folder with all your originals. Copy them out and delete the iPhoto Library and reboot, restart iPhoto and it should be recreated, which you can then import your copied originals again.
Note: using the same drive and user name as before, returning files exactly into their respective Music, Documents and Pictures folders like before matches any pathnames some files like iTunes has to the location of your files. If not done, then exclamation points will occur in iTunes when you click on a song. The iTunes Library will have to be opened in Text Edit and all the partial pathnames "find and replace" corrected to repair.
Optional, but recommended.
Ideally it's best to first Carbon Copy Cloner the 10.7 internal to another blank external HFS drive before doing the above steps 1-5 as that way you have a copy of everything in case you missed something or you need to hold option boot from the 10.7 clone. The clone can later be erased and used as a 10.6 clone. Or reversed cloned back onto the internal drive or as many external drives as needed. (don't boot a clone on a different Mac, you can access the files though)
Clones are hold option key bootable, TimeMachines drives are not.
Note: The above steps are ONLY for Mac's that didn't come with Lion preinstalled. For reverting a factory Lion to Snow Leopard requires other methods.

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.
