    Upgrading to Yosemite
    You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
    Upgrading to Yosemite
    To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

    Upgrading to Lion
    If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
    You can purchase Lion at the Online Apple Store. 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.

Second: I have a large music collection in my old Imac computer how do I transfer this information to my new computer? Also how can I share this information with other computers at home?

    I think you may find helpful information here:
    A Basic Guide for Migrating to Intel-Macs
    The Knowledgebase article Intel-based Mac: Some migrated applications may need to be updated refers to methods of dealing with migrating from PowerPC chips to Intel with the Migration Assistant safely. The authors of this tip have not had a chance to verify this works in all instances, or that it avoids the 10.6.1 and earlier Guest Account bug that caused account information to get deleted upon use of the Migration/Setup Assistant. However, a well backed up source that includes at least two backups of all the data that are not connected to your machine will help you avoid potential issues, should they arise. In event it does not work, follow the steps below.
    If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate.  Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
    Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
    Classic Environment, and subsequently any Mac OS 9 or earlier applications
    Screensavers written for the PowerPC System Preference add-ons
    All Unsanity Haxies Browser and other plug-ins
    Contextual Menu Items
    Applications which specifically require the PowerPC G5 Kernel extensions
    Java applications with JNI (PowerPC) libraries
    See also What Can Be Translated by Rosetta.
    In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
    If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
    If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
    The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
    Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior, TechTool Pro , SuperDuper , and Drive Genius  work properly on Intel-Macs with Leopard.  The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.  Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
    Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.
    Additional links that will be helpful to new Intel-Mac users:

    Transferring data with Setup Assistant - Migration Assistant FAQ
    Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs.  The initial section below discusses Target Disk Mode.  It is then followed by a section which discusses networking with Macs that lack Firewire.
    If both computers support the use of Firewire then you can use the following instructions:
    1. Repair the hard drive and permissions using Disk Utility.
    2. Backup your data.  This is vitally important in case you make a mistake or there's some other problem.
    3. Connect a Firewire cable between your old Mac and your new Intel Mac.
    4. Startup your old Mac in Transferring files between two computers using FireWire.
    5. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
    If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
    1. Set up a local home network: Creating a small Ethernet Network.
    2. If you have a MacBook Air or Late 2008 MacBook see the following:
    MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch, Late 2008)- What to do if migration is unsuccessful;
    MacBook Air- Migration Tips and Tricks;
    MacBook Air- Remote Disc, Migration, or Remote Install Mac OS X and wireless 802.11n networks.
    Copy the following items from your old Mac to the new Mac:
    In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
    In your /Home/Library/ folder:
    /Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)
    Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
    /Home/Library/Keychains (copy the whole folder) /Home/Library/Mail (copy the whole folder) /Home/Library/Preferences/ (copy the whole folder) /Home /Library/Calendars (copy the whole folder) /Home /Library/iTunes (copy the whole folder) /Home /Library/Safari (copy the whole folder)
    If you want cookies:
    /Home/Library/Cookies/Cookies.plist /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
    For Entourage users:
    Entourage is in /Home/Documents/Microsoft User Data Also in /Home/Library/Preferences/Microsoft.
    Credit goes to Macjack for this information.
    If you need to transfer data for other applications please ask the vendor or ask in the  Discussions where specific applications store their data.
    5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

    Be sure to start your iMac using its original grey System Install DVD: Insert that disc and start your Mac while holding the d key. At the Mac OS X Utilities screen select Disk Utility and format the hard disk. Select "Mac OS X Extended (Journaled)".
    Then, install OS X.

    Hi there, I have a 2009 Macbook - running on OS X V.10.6.8... but I'm looking at upgrading the Operating System to V.10.10.

    Thanks, Seamus

    Hey, problem solved. One of the drives was faulty. I erased the 2nd drive (which was showing up as the degraded raid slice), deleted the RAID set and restored the 2nd drive from a back-up disk image. After that, when I booted using 'option' I was presented with two boot disks but only one that worked. And when it did boot  up only the reformatted disk was showing in Diskutil so I'm guessing the second one is knackered. With it still in place the server still wouldn't boot up from a full shutdown, but the moment it was removed it booted up no probs. Wakes up from sleep as well so it seems sorted.
    So now just need to decide whether I'll bother with replacing the second drive or just use an external back-up. I have just bought a 1TB drive to back up to so will probably just go with that.
    Btw, is there anyway I can test the drive I removed to see if can be saved?
    Thanks for all your help. Your siamese twin comment was the push I need to erase the drive, I'd be holding off before that.

    If you look at the User Tips tab, you will find a write up on just this subject:
    https://discussions.apple.com/docs/DOC-4053
    The subject of buying/selling a Mac is quite complicated.  Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
    SELLING A MAC A
    Internet Recovery, and Transferability of OS & iLife Apps
    Selling an Old Mac:
    • When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
    • Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
    Internet Recovery:
    • In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
    • Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
    iLife Apps:
    • When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
    • Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
    • It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
    SELLING A MAC B
    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
    A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
    B. Clone to an external drive using using Carbon Copy Cloner.
    1. Open Carbon Copy Cloner.
    2. Select the Source volume from the Select a source drop down menu on the left side.
    3. Select the Destination volume from the Select a destination drop down menu on the right
    side.
    4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
    sure to opt for that.
    Destination means a freshly erased external backup drive. Source means the internal
    startup drive. 
    Step Two - Prepare the machine for the new buyer:
    1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
    2, Remove any Open Firmware passwords or Firmware passwords.
    3. Turn the brightness full up and volume nearly so.
    4. Turn off File Vault, if enabled.
    5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
    Step Three - Install a fresh OS:
    A. Snow Leopard and earlier versions of OS X
    1. Insert the original OS X install CD/DVD that came with your computer.
    2. Restart the computer while holding down the C key to boot from the CD/DVD.
    3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
    Optionally, click on the Security button and set the Zero Data option to one-pass.
    4. Install OS X.
    5. Upon completion DO NOT restart the computer.
    6. Shutdown the computer.
    B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because
    it is three times faster than wireless.
    1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
    Utilities window appears.
    2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button. 
    3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
    on the Erase tab in the DU main window.
    4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
    and set the Zero Data option to one-pass.
    5. Click on the Erase button and wait until the process has completed.
    6. Quit DU and return to the Mac OS X Utilities window.
    7. Select Reinstall Lion/Mountain Lion and click on the Install button.
    8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

    I'm selling my computer. Everything has been erased. Now the operating system, Lion, needs to be installed. I believe the computer did not come with a cd so reinstalling is done through wifi.

    We bought it in January 2010. I'm not sure what OS it came with but when I look at the dates of each OS on wikipedia it looks like it came with Snow Leopard. The only disk I happen to have is Leopard.
    Let's drop back a minute and go through what you can and cannot do with this machine.
    1.  If the machine came with Leopard, you can install Leopard and then go to Snow Leopard and up the line of the on-line Mac OS X versions, that is, Lion, and Mountain Lion and Mavericks as compatible.  If the disk for Leopard that you have is a grey face disk, that is a machine-specific disk and will only work if it is the disk that came with your MacBook Pro.  If it is a panted face (black) with a large silver X it is a retail version and will install IF your machine came with Leopard.
    2.  If your MacBook Pro came with Snow Leopard, it will not install Leopard.  If it came with Snow Leopard and is a 2010 machine, it will not install the retail version of Snow Leopard since that is 10.6.3 and the 2010 and later machines came with 10.6.6 preinstalled.  You must call Apple Customer Support and have them send you the machine-specific install disk for that machine.  There is a fee of something like $20 in the US for doing that.
    3.  If your machine came with Snow Leopard, you need to reinstall Snow Leopard and then move to the on-line Mac OS X versions, you cannot download a version with your Apple ID associated with the version currently on the machine.  The starting point HAS to be Snow Leopard for the new owner to do an on-line Mac OS X download.
    4.  With Snow Leopard installed and on-line software updated to 10.6.8, the new owner can then move up to Lion or above depending on the compatibility of the hardware.  To move to Lion or above the machine must have an Intel Core 2 Duo processor.  To move to Mountain Lion or Mavericks the machine must meet the requirements in http://support.apple.com/kb/HT5842. 
    At any rate, the new owner must install Snow Leopard on that machine before any move to one of the Mac App Store versions of Mac OS X.
