Is there any course or complete tutorial to learn how to DJ using this combo (djaypro + Pioneer DDJ FLX-4)???

Over the past year, I've learned a lot about mixing with djaypro. I got the annual membership, and it's been great. However, I feel like I haven't been able to get the most out of the DDJ-FLX4 because I haven't found it very optimized for macOS software. Should I switch to rekordbox? Even though I'm already used to the versatility and the number of platforms djaypro supports.
