An Update is a free change to add to the base code or as a bug fix within an existing Operating System. Such as the .8 added to 10.5.
An Upgrade is a complete new Operating System that must be purchased. Such as 10.5 Leopard to 10.6 Snow Leopard.
10.5 Leopard was written for Power PC Macs with code added to force it to run on Intel processors.
10.6 Snow Leopard has completely rewritten code and only runs on Intel Macs.
10.7 Lion used some 32 bit which allows it to run on Late 2006 through Early 2008 MacBooks and a lot of 64 bit code.You have to upgrade to 10.6.8 to be able to download iTunes 11. The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard After you’ve installed that then download the 10.6.8 combo updater to finish it off. http://support.apple.com/kb/DL1399
System Requirements for 10.6:
- Mac computer with an Intel processor
- 1GB of memory
- 5GB of available disk space
- DVD drive for installation
- Some features require a compatible internet service provider: fees may apply.
