Hello, This is my first post ever and I really need some advice about some software. I am clueless about some of the software, so please be kind. I have Mac OS X Version 10.5.8 with a Intel Core 2 Duo processor. I cannot get the Mac App Store on my dock, even though I've run an update and my computer says all my software is up to date. I would also like to get the OS X Lion, but I don't know where I would find information about my current operating system and if it's a Leopard or not. Could someone help me with figuring all this out? Thanks!
