Meta for versions of Mac OS X below 10.10
Meta only supports Mac OS X 10.10 and above (Yosemite, El Capitan). If you use an unsupported version of Mac OS X, you can either use the web version of Meta by visiting https://app.meta.sc/ in the browser or upgrade to the latest OS X to download the Meta Mac application.
For the best Meta experience, we definitely recommend using the Mac application. With the Mac application, you can sync files on your computer with Meta and open them in the applications you're familiar with (Word, Excel, Pages, Keynote, etc.) You'll also be able to open Meta right from the Dock (or with a keyboard shortcut!) instead of having to use Meta in the browser.
We've helped some other users upgrade to the latest version of Mac OS X so they could download the Meta Mac application, and we’re happy to help you too! Let us know if you’re interested - we want to help you take advantage of all Meta has to offer!
