using tascam portastudio 2488 to record vocals in ableton

i'm new to this site and pretty new to setting up midi keyboards and control surfaces and i honestly have no idea if i can use this to record vocals in ableton live. but if i can...how do i do it?

i'm able to set up my midi keyboard to my computer and use it in both ableton and reason but not this. i bought this a long time ago to record my band but never had to sync it to my computer. do i need to install any software so it'll connect with my mac?

any help would be greatly appreciated
