DJAY for imac

Hi I’m new to the djay app and have hopefully a simple question. On my iPhone when I press the sync button it automatically starts the song in sync both with bpm and volume level. I just slide the mixer over while recording and done.
My question is can this be done on the mac version?
All I’m looking to do is mix 2 songs by beat, volume level and transition time just like the iPhone version. Nothing else.

I’ve pressed that automix button and it’s grabbing songs at random. I want to be able to mix the 2 songs that I choose and record the mix.
Help
