If you have purchased your system in 2007 or later, then you should be good to go for upgrading to OS X Lion; however, you can check for the processor type on your system by going to the Apple menu, selecting 'About This Mac,' and then looking at the Processor section. If you see Core 2 Duo, Core i3, Core i5, Core i7, or Xeon in the processor name, then you should be good to go. If you only see Core Duo (without the number 2 in it), Core Solo, or any form of PowerPC, then you will not be able to run Lion. Beyond the CPU requirements for Lion, you may also consider upgrading your RAM to at least 2GB, but preferably 4GB if possible.
Macs in around 2007 to 2008 shipped with between 512MB and 2GB RAM, and Lion will require at least 2GB of memory to run adequately. You can see how much RAM is installed by going to the same About This Mac window, but consult your Mac's manual to see how much RAM you can install; some models can only upgrade to a maximum of 2GB of RAM. Upgrading current installations If you have a current OS X installation, unlike previous releases of OS X, Lion will not be able to upgrade from all of them; its requirement for the latest version of the Apple Store application will require you to have the latest OS X 10.6.8 version installed. This means that if you are running any version of Tiger or Leopard on an Intel Mac and wish to upgrade, then you must first purchase and install Snow Leopard, and then upgrade it.
