10.6.8 Combo Updater
Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
- MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
- MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
Your Mac needs:
- OS X v10.6.8 or OS X Lion already installed
- 2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
- 8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.

Do a backup before installing.
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again. You can make a bootable USB stick to install using this free program.

The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a machine supposedly limited to 4 GB.
