To see what is posible...

At the Apple Icon at top left>About this Mac.

Then click on More Info>Hardware and report this upto but not including the Serial#...

If yours is a PPC iMac you cannot upgrade any further. If it is an Intel iMac:

Start by checking if you can run Snow Leopard:

Requirements for OS X 10.6 'Snow Leopard'

http://support.apple.com/kb/SP575

(NB: PowerPC applications can still be run in Snow Leopard using Rosetta, but they will not work in later versions of OS X. For detailed information see this user tip: https://discussions.apple.com/docs/DOC-6271 )

The OS 10.6 Snow Leopard install DVD is still available for $19.99 from the Apple Store:

and in the UK:

but like Leopard, Snow Leopard is no longer supported by Apple in terms of security updates.

When you have installed it, run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8, or download the combo update from here:

http://support.apple.com/kb/DL1399

Check via Software Update whether any further updates are required, particularly to iTunes (you will need the latest version in order to synch with mobile devices).

You should now see the App Store icon in iTunes, and you now need to set up your account:

You can now upgrade to Mavericks OS 10.9 for free IF you have one of the following Macs, with not less than 2GB of RAM, and at least 8GB of available space on your hard drive:

iMac (Mid-2007 or later)

MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)

MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)

MacBook Air (Late 2008 or later)

Mac Mini (Early 2009 or later)

Mac Pro (Early 2008 or later)

Xserve (Early 2009)

iCloud system requirements:

If you cannot run Mavericks you can purchase the code to use to download Lion from the App Store (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard):

or Mountain Lion:

Rosetta is an "optional" install to be checked when installing Snow Leopard (and IMHO, QuickTime 7, too!).

There is active debate on whether or not Apple is "no longer supported by Apple in terms of security updates."

This speculation began in February, when Apple released a security update that did not include an update for Snow Leopard. Subsequent discussion resulted in the information that the problem to be solved in that security update was not present in Snow Leopard and hence, no need to patch Snow Leopard with that security update.

Since then, Apple has updated FaceTime for Snow Leopard:
