I can't play sims 4

[Destinyaqua2005]

Even though I've downloaded the game it won't let me play. It won't let me sign into origin either. I can easily sign into my EA account but when it comes to origin it won't work. It keeps showing the following message: 

"Sign in failure 

Sign in is currently unavailable. Please try again later."

For the past 24 hours, it has been showing this message. I can't sign in on my iMac but when I signed in on the Windows computer it worked just fine. Going back to the problem of not letting me play the game, on both the Windows and the iMac they both say the same error message.

"TS4_x64.exe - Application Error

The application was unable to start correctly (0xc000007b). Click OK to close the application."

I want to be able to play the game since I've seen so many gameplays on it and have been wanting to play this myself. It disappoints me greatly to see that my game won't work.
