(Note: Snow Leopard will not install on some newer Macs made after mid-2011, but some of these Macs will run Snow Leopard although Snow Leopard will not install - there are ways (by using older Macs) to get Snow Leopard running on some newer Macs without installing. Make certain that your Mac is compatible with whichever OS you plan to upgrade to.

For Lion (OS 10.7) or Mountain Lion (OS 10.8), you need to go to the online Apple Store to purchase and get info on how to download. From there you should be able to download and upgrade to the most current OS (currently OS 10.9 – Mavericks). Go to the Applications folder and open “App Store”. If you wish to upgrade FROM Snow Leopard, make sure you are running OS 10.6.8. This maximizes performance, but for notebooks, it may run down the battery faster. If it is not set to 'Highest', set it to that right away. Afterwards you can start up from your old OS or Snow Leopard by pressing OPTION key during startup. Go to Preferences, Energy Saver, Options and look at the drop box down near the bottom called Processor Performance.

Alternatively, install Snow Leopard to a empty partition that has been formatted as Mac OS Extended (Journaled) with the GUID option. It seems that Snow Leopard is using more wired.
however, I recommend making a complete bootable backup before doing so in case something goes wrong during installation, such as power outage. 1 My installation of Snow Leopard is reporting that I have 1.75GB of memory under the pie chart representation in Activity Monitor. Many people simply upgrade directly over the old OS installation. Quitting Safari releases a big chunk of memory to free memory. (This model is limited to 2GB of physical RAM.) In turn, the growth of wired memory use appears to be related to Safari. After installing, do Software Update (under the Apple Menu) to bring Snow Leopard up to OS 10.6.8. The problem seems to be related to gradual growth in the size of wired memory, which starts out at about 1/2 GB and grows to 1.5 GB or more. If your Mac does not have an optical drive, the DVD has instructions on doing a remote install from another Mac on the same network. Then purchase the Snow Leopard install DVD from the Apple Store. (If the word “Intel” appears anywhere beside “Processor” you have an Intel-based Mac.) To find out go to Apple Menu and select “About This Mac”. Noticing a wild goat grazing below, the feline creeps across the ledge on her silent, furry footpads.
The animal’s spotted beige fur allows her to blend in almost completely with the rocks, making the cat a nearly invisible hunter. If you wish to upgrade TO Snow Leopard (OS 10.6), make sure you have an Intel-based Mac (Snow Leopard will not run on a PowerPC processor) with at least 1GB of memory and has Mac OS 10.5 or earlier.
