I have successfuly installed OSX Catalina on my Ryzen 7 2700x system and everything seems to be working fine out of the box. The only issue I am having is with these consistant temperture spikes that happen. I have a AIO water cooler hooked up to my CPU and consitantly the idle temperature is 39 C to 40 C both on linux and windows. On this mac installation I the temperature starts reaching low 40 degrees and all of a sudden one of my cores spike in usage while the others are at a lower state. This casuses both my temperature and power usage to go up. I have attached two screenshots demonstrating this issue. This is with no programs started up and on idle. I have attached my EFI folder excluding my config.plist. Maybe someone might have an idea. The hardware I am running are: CPU: Ryzen 7 2700x MOBO: Gigabyte B450M DS3H 16GB RAM @ 3000 Mhz and installed on a 250GB Kingston SSD.
