The iTunes "buy" button doesn't seem to be working. I click it and nothing happens. Anyone know why? Thanks.

Apple made some sort of programming change on 12.26.12 to their iTunes system that suddenly made the Buy button non-functional specifically in the directly-out-of-the-box Snow Leopard (10.6.3). [I had Leopard, same as you, 10.5.8, and that was still working then. I installed Snow Leopard a couple of days ago to my MacBook, and discovered the Buy Button didn't work.

First step: Pull down "Software Update" from the Apple menu (that annoying thing we always ignore.) If you're using Snow Leopard 10.6.3, it'll upgrade you for free to 10.6.8, and that should solve your iTunes problem. (I don't know if there are any upgrades for 10.5.8, but unlike the other ungodly system upgrades, Snow Leopard is only $20. Because Apple is growing increasingly stupid, you can't buy it online--you have to call customer care.)

Hope this helps. Let me know if it does.

You can buy Snow Leopard from the apple store and they will send out the cd

I don't have Snow Leopard, but I just clicked software update and it worked. I installed the updates and restarted my computer and the buy button now works. Thank you so much!!!
