How to find which version of macOS (OS X) you are using?

Before you purchase and install a Kaspersky Lab application, make sure your Mac meets system requirements.

For correct installation and performance, your Mac must be running OS X 10.6 or later.

To find the version number, in the OS X menu, click  and select About this Mac (or About this Computer in OS X 10.6).

The information about the version will be available in the window that opens.
