Q: How can I verify if I meet the requirements to use ICloud?

You must be using 10.7.2 or later for iCloud. You have 10.5.8.

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.

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 Mavericks 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 iCloud services; fees and

           terms apply.

Upgrading from Snow Leopard to Lion or Mavericks

To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. 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.

     OS X Mavericks- System Requirements

       Macs that can be upgraded to OS X Mavericks

         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.

Are my applications compatible?

         See App Compatibility Table — RoaringApps.

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.

     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.

To use iCloud directly from your MacBook Pro, you must have at least Mac OS X 10.7.5, Lion, or higher versions of Mac OS X.

10.5.8 cannot do things like sync or use PhotoStream directly with iCloud.

Hi Kappy,

10.7.2 was when we first got access to native iCloud, but all you can get now from Apple is 10.7.5, so...

True, but someone still using 10.7.2 need not upgrade. I'd rather not confuse the issue. I stated 10.7.2 or later, Ralph.

Yes, but I wanted to poke you for a change...so unusual to get the opportunity.
