I have an iMac which I have had for about 4 years. I am not technical and didn't realise how important it is to update the operating system...
I need to update and I never have! Its currently OS X version 10.5.8
What do I need to buy to update to the newest one? Do I have to go through all the updates or can I just put in the new OS if I buy it? I'm quite confused. Please help!
