II can't find icloud icon in systems preferences (to make an upgrade)
I run 10.6.8
MacBook Pro, Mac OS X (10.6.8)
Open the Mac App Store and try purchasing Mountain Lion 10.8. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Core 2 Duo(not Core Duo) or better CPU with at least 2GB of RAM, and if it does, phone the online Apple Store and order a download code for Lion 10.7.
