Hello, Now it's like this that I upgraded my iMac to the Lion in the release. I find beach balls and many program crashes very often. I also feel that the internet connection is worse than before. I came in now that I have Adobe CS4, which I would like to install again and start editing photos as a component to Aperture. CS4 seems to only work on the Snow Leopard. I myself think that the old Exposé and the Finder is much better than what they are in Lion. So it speaks strongly to me to go back to the Snow Leopard.Is it worth to downgrade or do you let the Lions remain? I would like to have experience of you on the forum what you have to experience and if you intend to stay in Snow Leopard. As I understand it should icloud come even to the Snow Leopard and so usually developers to make software support for Leopard and Snow Leopard? It's so easy to be wise if I knew I'd neglected to upgrade to Lion. How can I most easily backup of everything? I am very very scared about my pictures even music. I think I managed to do a backup in Time Machine for the pictures in Aperture, but am not sure. How to remove backups that have been made in Lion in the safest and best way? Thanks for answer in advance.
