Can't import Raw file to Lightroom CC

I've struggled with it a long time and read multiple topics but still can't find the solution.

When i took picture i took both JPEG and Raw format. I imported them to iPhoto on my MacBook Pro and i can see there is a little "J" label on my pictures so i know the MacBook has stacked my Raw file and JPEG file. Now when i tried to import the picture to the light room, it will only import the JPEG format. It won't import the Raw format.

I tried clicking the 'preference' in lightroom, hopping to find import preference, where i can check the box for "treat Raw file and JPEG file as separate file". But when i click the "preference", there is no such option at all. What i can see is (on the left), Account, Local storage, General and Interface. I went to all 4 selections and i can't find the option for "treat Raw file and JPEG file as separate file". Under the General, the option i have is only "prevent system to sleep during sync while connect to power", "Use Graphics Processor", and Import "Add copy right to imported images". Why i can't find the option to "treat Raw file and JPEG file as separate file"??

Btw, when i import the photo to light room, i don't go to a folder find the pictures since they are loaded to iPhoto. The only place i can find my imported photo is under Media, under Photo, and iPhoto library.

Can somebody help please. I am so confused.
