I have a soft-bricked factory reset Samsung Core Prime. I use a Mac. What do I do?

So i recently tried installing Chainfire, and boom, instant soft-brick. So, when i went to factory reset, thinking that would fix my phone, i found it factory reset, but, it still is soft-bricked. Not boot-looping, but its stuck on the boot screen. It is rooted.. How do i go about fixing it? I use a mac, so windows software is of no use to me...
