Missing System Requirements Error 4.13

Greetings all,

When ever I try to install version 4.13 I get this alarming error message. Haven’t ever had the problem before. My computer is Yosemite OS X version 10. 10.2

Hello Van2015,

To use version 4.13 of UE4, you’ll need to update your OS X version to version 10.10.5 or higher. It may be able to launch, but there may be issues that you’ll run into that we have not accounted for. As we move forward, we will be dropping compatibility for older versions of operating systems as the newer versions become more commonplace. You can continue to reliably use 4.12 and any earlier versions if you do not wish to update.

You can find more about the minimum requirements on this page after selecting Mac OS at the top.
