Hi I have used ME Version 3.3.2 (3.3.2.03) and Serato 2.4.1 since purchasing my Mac Book in 2020. Everything has been running perfect with mix emergency. l am using the ddj Sx2 Pioneer controller and it hasn't skipped a beat, therefore the thought of updating both Mac and mix emergency scares me. l do gigs functions weekly and feel if l mess with anything l with have glitches issues etc and then can't work any of my gigs. To add to my dilemma l was given a ddj 1000srt as a gift and l feel l need to purchase another Mac to use with that controller incase I have issues when updating to that. Am l over reacting? Should l update everything? With both controllers work seamlessly with newer latest version of Mix emergency, the iOS Catalina 10.15.6 and Serato 2.4.1? How would benefit and am l missing out on much, not updating Version 3.3.2 (3.3.2.03)? If so what major benefits am l missing out on? l would love to hear your thought? Thanks in advance.
