13 inch mid 2012 2.9ghz i7 16gb 1600 Mhz DDr3 intel graphics 4000 1536 High sierra 10.13.5 Im using 2.7.1 mix emergency, i know its old but it works fine with me. well it used to until this. Ok, the problem I'm having is, every time i start using video on mixemergency or serato dj video, the computer meters jumps to redline in the serato dj computer meter... I've optimized video resolution, latency etc.... and it keeps jumping to redline on the serato dj computer meter. When i switched to mp3s only, the computer meter goes way down... I use a 2gb wd external hd also. Help, thanks nick
