Galaxy S4 GT-i9500 Issue

[AC Question]

Hello, I have a Galaxy S4 GT-i9500. Before i used to sync my phone with the USB cable with my mac and it would work. And today I tried syncing it, it didn't work. Normally when the S4 is connected to a computer, there is a notification connected media device ... (where you can press and choose MTP and Camera preference). Well I have none of this. I downloaded Kies and Android File Transfer, it won't recognize it. Please help me solve this issue.
Thanks

I would try downloading and installing updated drivers on your PC.
