My iMac version is 10.5.8. I need to update this version to a later one, so I can synch my new devices with iTunes.
What do I need to do do update the current version of my iMac?...
The first step in Upgrading... is to Snow Leopard = OS X 10.6.x
It is Not available as a download... It is a Paid Upgrade.
Do this first...
Check that your Mac meets the System Requirements for Snow Leopard...

If so... Purchase a Snow Leopard Install Disc...

After the Successful Install, run Software Update to get the latest updates for Snow Leopard and iTunes.
Be sure to make a Backup of your Current System Before Upgrading...
