Can I upgrade to Snow Leopard, and then Mountain Lion, on my 2009 MacBook with OS X 10.5.8?

I want to upgrade to Snow Leopard so I have access to iCloud for all my devices. I bought my MacBook mid 2009 and am currently running OS X 10.5.8. Does anyone know if I am able to upgrade before I go and buy Snow Leopard?
Thanks.

You can upgrade from 10.5 to 10.6 with no problems. Any program that runs under 10.5 should run under10.6. See this list for compatibility with 10.6: http://snowleopard.wikidot.com/
You might have to upgrade some drivers for printers, etc.... And you will have to install Rosetta if you have any third party Power PC applications http://www.macobserver.com/tmo/article/snow_leopard_installing_rosetta/
You can order a Snow Leopard 10.6 install disk for $29 from the Apple Store as long as you have at least 1gb of RAM and 5gb of free space on your hard drive. http://store.apple.com/us/product/MC573Z/A?mco=MTY3ODQ5OTY
To upgrade your iLife and iWork. If you only want iPhoto or other single apps from iLife '11 you can get them from the App Store after you've upgraded to 10.6.6. iPhoto, iMovie or Garage Band for $15 each and Pages, Keynote or Numbers from iWork '09 for $20 each.
Once you are at 10.6.8 you can buy Lion for $29 from the App Store if you have at least a model 2,1 MacBook. Lion will require at least 2gb of RAM but really needs 4gb to run smoothly. As for third party programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

2006 a1150 MacBook Pro 10.5.8 leopard. Can I upgrade to Snow Leopard and then Mountain Lion?

My daughter has 2006 A1150 MacBook Pro with the following listed under "About this Mac" : Mac OS X 10.5.8 Leopard, Processor: 2 GHz intel core duo, Memory: 2 GB 667 MHz DDR2 SDRAM.
Can we upgrade to Mountain Lion, after Snow Leopard, with this model and op system? Thank You.

If this is your MacBook Pro, it has only a Core Duo processor, and the highest Mac OS X it can run is 10.6.8:

Complications migrating from Snow Leopard Server to Mountain Lion Server.

I'm migrating from Snow Leopard Server to Mountain Lion Server. The article "OS X Server: Upgrade and migration" (http://support.apple.com/kb/HT5381) says
"Make sure that any DNS or DHCP servers on which your server depends remain running during the upgrade"
This advice is reinforced by the details of the article "OS X Server: Steps to take before upgrading or migrating the Open Directory database" (http://support.apple.com/kb/HT5300).
As the server I'm migrating from provides these services it will need to be running during the migration process. This would seem to limit my options to doing the migration from a Time Machine backup (or, making a seperate clone of the server's drive and connecting it externally to the new box)
My main concern is the seemingly inevitable clash that is going to occur on the network as the new server takes on the roles of the old one - while it is still running.
What are my options here ?
This is my second attempt as on my first try I did the migration from the TM backup with the network down - and none of my local network users or their home directories were migrated, although the settings for the mount points were, but there were no actual directories where they pointed to!
Clear directions on how to procede would be VERY MUCH appreciated
Thank you.

Moving from Snow Leopard to Mountain Lion means first installing the client (non-Server) version of Mountain Lion and then install Server.app this means that for at least part of the process you will not be running DNS, DHCP or Open Directory.
If you are going to end up using the same DNS name and IP address after the change then an approach you could follow would be as follows.
Destroy any Open Directory replicas
Archive your Open Directory Master (to make a backup)
Note down your DNS records in case they get messed up
Export via Workgroup Manager your users, and groups (you might not need this but better safe than sorry), make sure you do not include the diradmin account
Keep a full back of the server (you should always have backups)
Note down your DHCP server settings in case they get messed up
Note down any other service settings
Install Mountain Lion
Install Server.app
Install Workgroup Manager (extra free download)
Run Server.app
Make sure settings for services are as much as possible the same as before
If your lucky that may be all you need to do, otherwise...
Restore Open Directory archive, if your lucky that will be all you need to do, otherwise...
Make new Open Directory Master
Run Workgroup Manager
Import users and groups you previously exported
You will then have to set passwords for each user as these are not preserved via Workgroup Manager export
When I did this, I was also being forced to change all my IP addresses so I had no choice but to use Workgroup Manager to export and import accounts.

Cannot upgrade from Snow Leopard to Yosemite

I have a MacBook from late 2009 with 4 GB memory and plenty of hard disk space. When I attempt to upgrade to Yosemite via the App store it says "This version of OS X 10.10 cannot be installed on this computer". Even though the computer was purchased new at the end of 2009, is it possible it does not meet the hardware specs somehow? Am I doing something wrong? Thanks in advance.

I'm having a similar (related?) problem with a 2009 MacBook. The upgrade from Snow Leopard to Yosemite started off normally, but the installation is not working - progress bar gets about halfway and then stops...for days.
A guy at the Genius Bar told me that happens sometimes if there's a blip in the internet connection during the process. Apparently, the resolution is to wipe the drive and reinstall. Unfortunately, I didn't back up the drive prior to the installation thinking this was just one of those upgrades that the OS or various apps (e.g. iTunes, iPhoto, etc.) always want me to install, which I do, never having had a problem.
Although, the Genius tested the drive and found it to be in perfect condition, I was told that I need to go to an external company to have the data recovered because Apple doesn't do data recovery.
Is it true that I have to wipe the disc and start fresh? I have the original Snow Leopard disc, so can I simply reinstall Snow Leopard? When I hold down the option key on power up, it shows me two images - Macintosh HD and Recovery- 10.10. Should I try Recovery- 10.10?
I would appreciate any thoughts, suggestions, ideas, alternatives, etc.

Cannot upgrade to snow leopard

I have a late 2007 iMac (2GHz core 2 Duo). Since I purchased it, it has run Tiger, then Leopard flawlessly. I recently bought a Magic Trackpad which required me to upgrade to Snow Leopard. Unfortunately, 10.6 seems to kernel panic almost as soon as it boots up. If I downgrade back to 10.5, all works fine again. I have tried the following:
1. Clean install of 10.6 = kernel panic once the OS boots
2. Clean install using another 10.6 installation disk = kernel panic once the OS boots
3. Swap out RAM = kernel panic once the OS boots
4. Boot from an external 10.6 disk = kernel panic once the OS boots
More often than not, I can boot into safe mode with Airport disabled although sometimes (seemingly random) that also kernel panics. I am completely stumped here and would appreciate any help please. I don't want to be stuck in Leopard for all eternity! BTW I did take it into the Apple Store, and the "geniuses" claimed it was fixed - took it home and it wasn't. Below is the output from the kernel panic log:

Are you trying to boot off a 10.6.5 updated system, or a 10.6.5 installer DVD from another Mac? According to;
http://en.wikipedia.org/wiki/MacOS_X10.6
The build and Darwin version belong exclusively to 10.6.5.
Your Mac can only boot off 10.6 and 10.6.3 retail to install 10.6, as well as systems upgraded from those 10.6 installations on your specific model and vintage iMac. But it can't boot off another Mac's installer. The 10.6 installer DVD must look like *
and not say Upgrade, Dropin, or OEM.

Cannot buy osx mountain lion as the app store rejects my password

Help how can i get the osx mountain lion?

Also keep in mind, that with the recent (or maybe not so recent) password update, the Apple ID password must include:
At least 1 letter
At least 1 capital letter
Must not contain multiple identical consecutive characters (eg: ffffff)
Must nor be the same as the account name
Be at least 8 characters total
and must not be a common password (im not going to lie, i have no idea what that means)
So if this helps narrow your search down, I'm glad!
Good luck!

Error configuring services from Snow Leopard Server to Mountain Lion Server

I am trying to upgrade a Snow Leopard Server Mac Mini to Mountain Lion Server.
We have two Mac Mini servers at our office (production and backup) so I migrated the everything from our production server to the backup using the migration assistant when setting up the backup computer.
I now have the backup at home trying to upgrade it to Mountain Lion Server. I have downloaded and installed Mountain Lion as well as the Server App version 2.2. I basically followed the simple directions found in the Apple documentation.
I started the server app and it got to the part where it said "Upgrading services". After running for a few minutes, I get a window that states "An error occurred while configuring your server." It also sayd "The following actions failed or were not attempted:" with a red dot next to "Upgrading services". The other three items: "Authenticating to local directory", "Reading directory configuration" and "Authenticating to local directory services" have gray dots so I'm sure they were not even attempted.
Our Snow Leopard server is setup for SMB file sharing, LDAP services, FTP, Web, DNS, DHCP.
Can someone point me to where I can figure out what exactly is failing? Are there specific log files I need to look into?
Thanks

Have EXACTLY the same issue - also tried reinstalling mountain lion server fresh and still had the same problem...

How do I restore my operating system from Snow Leopard back to Mountain Lion on line after erasing my hard drive?

I had to erase my hard drive. I loaded Snow Leopard with the disk I got with my computer, but I purchased Mountain Lion several months ago and don't have support any longer. How do I get back to the Mountain Lion operating system, on line?

Upgrading to Snow Leopard
You can 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.

If you have no need for the new features of Mountain Lion and you have important software that will not work with Mountain Lion, then there is no reason to upgrade at this time.
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.

Worried upgrading OSX Mountain Lion 10.8 because of...

Hi to All!
I'm already a MBP user for 1 year and since then I didn't upgrade my OSX. I'am worried because the time I bought my MBP one of my friend upgrade the OSX to 10.8 by using his usb thumb drive I didn't have the chance to asked hm if that is pirated or good because of excitement , I want to ask him these days but unfortunately he is unable to contact.
So my question is... is it safe to update my OSX 10.8 to 10.8.4 (latest version) thru App Store by clicking the update button? because I am just thinking if my friend update my OSX using pirated or not good stuff I'am worried that Apple might block my MBP or something and if that so I might stay on this version for good, I would like to buy the 10.8 before if I it is required in order to stay legal.
Please help!
Advance Thanks!

Yes, it's safe. Do this:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears.

When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

How do I upgrade Snow Leopard Server to Mountain Lion (client)?

I have a Mac Mini Server edition (2010) with Snow Leopard Server (10.6.8) pre-installed. I don't like the interface of Server edition because 1) I don't need the server functions and 2) I prefer client OS's easier (less powerful I know) interface to do sharing, logging in, configuring.... etc.
(I know I should've bought the non-server version with a DVD drive but I can't take it back now.)
My question is, what's the easiest way of changing it to a 'client OS', preferably to the latest Mountain Lion? From forum posts it seems downgrading from 'server' to 'client' will definitely require a fresh install. That's fine. I can move all my personal files to the second HDD in the Mini and do a fresh install of OS on the first HDD.
I can see 'Mountain Lion' upgrade in the App Store, but it doesn't say if it's server or client. I am assuming it's a server upgrade?? What will happen if I purchase it for £13.99 in App Store? Or is there an alternative way?
I have a USB Apple optical drive. I have a USB thumbdrive too for storing the OS image if required. Thank you. Any tips will be appreciated.

I went to the AppStore and as I was running Snow Leopard Server it prompted me to purchase Lion Server which I didn't want.
Luckily, I wasn't asked to purchase the 'Server' when I upgraded from SLS to Mountain Lion via the AppStore. I think your particular problem was mentioned in some other posts where the upgrade path to Lion became an infinite loop (hmmm... ). But that's all in the past now. Glad it all worked.

Can I upgrade my MacBook Pro from Snow Leopard straight to Mountain Lion, or would it be wise to get Lion as well?

I am currently in the process of upgrading the operating system on my girlfriend's MacBook Pro (Model Identifier: MacBookPro5,1). I have purchased and installed Snow Leopard successfully, however I would like to upgrade to the latest operating system, which to date is Moutain Lion.
Am I able to do this?
Is it wise to perform such an upgrade on this model of MacBook Pro (can it handle it)?
I have heard that I can upgrade straight from Snow Leopard to Mountain Lion. What are the advantages and disadvantages of doing this? Will I lose anything at all by not installing Lion before Mountain Lion?
Thanks for the help everyone. Hopefully I can get these questions answered soon.

And the only way to figure that out would be verifying my disk using the Disk Utility?
Thank you for that. If I am not missing out on anything by skipping Lion then that will be my option. A few extra dollars in my pocket is always a good thing.

Upgrading U.S. Snow Leopard using DE Mountain Lion??

Hi all,
I'm currently using OS X 10.6.8 on a MacBook Pro (capable of running Mountain Lion) and I want to upgrade as soon as Mountain Lion is released.
But my concern is that I have a copy of Snow Leopard (my current system) which I bought in the U.S. and I want to use the German Mac App Store to buy Mountain Lion (for payment reasons) and then upgrade the (U.S.) Snow Leopard.
Is this possible? I'm asking because I'm not familiar with Licenses involved in the Upgrade. Also, can I use a different Apple ID for Mountain Lion (during the setup process) than the one I used to buy it in the Mac App Store???
And last, will the Mountain Lion Upgrade Installer create that mystical "Recovery Partition"?
If so, is there any way to disable that because it will mess up my partition setup (I'm using Ubuntu beside Mac OS X using one of those freaky hybrid MBR setups)?
Thanks in advance

Thanks for the suggestion.
I'll see if I can install it when it comes out (if there is a license issue, I probably won't even get past buying it in the App Store...)
One Apple Support document mentioned resizing Macintosh HD (making it 128 MB smaller leaving unallocated space) if someone had multiple partitions.
I just wanted to know if the Mountain Lion installer resizes Macintosh HD by a certain amount to free space for the recovery partition, or if the installer just puts the partition at the end of the disk, ignoring other partitions completely (which is unlikely).
