You will not be able to run SpiderOak ONE, Groups, or Enterprise on Mac 10.8 Mountain Lion or older. SpiderOak's backup products requires at least Mac 10.9 Mavericks. If you are still running an older version of macOS, you will need to upgrade your operating system before you can use SpiderOak backup products. This is a free upgrade available from Apple's App Store.
