I have tried to upgrade to the free Yosemite but it is impossible without giving credit card information. I have had about 20 e-mails with Apple most of which tell me I can download without giving credit card details but all prove to be false. One e-mail told me I could create a fake I/D but Apple would let me do that without me giving my name and address and telephone number which doesn't help because Apple does not recognise the country in which I live. I was even directed to Spanish speaking Mexico and Portuguese speaking Brazil for help but since I speak neither of those languages, it wasn't much help. I was told to speak to the U.S. which I have to do on an international call. After several minutes of 'jumping through hoops', I was told I would have to wait five minutes for an adviser. I put the 'phone down. If Yosemite is free then I ought to be able to click on a download, no questions asked. I paid cash for my last upgrade in an Apple store, no one asked me for anything. What has happened to Apple's legendary service? Gone the way of Microsoft.
