I want something like FL Studio.
...and people in H E L L want ice water.. but that doesn't mean they will get it.... 🙂
Seriously though.. For what you want.. buy the PC version of FL Studio (as you don't want to run the Mac beta) and bootcamp your Mac to run Windows....
Mac Basics: Using Windows on your Mac with Boot Camp
or...
Invest in the Maschine hardware and Maschine software for the Mac....
or..
Buy an MPC.. either hardware version or get an iPad and use the app Pro version or the Fly30 version..

You could simply google Making beats in Logic Pro X and watch any of the myriad of videos there...
