Hello @roon-user-tin,
Thank you so much for raising awareness about the high CPU usage. I’m so sorry it took us this long to get back to you - we would have hoped it was going to be much sooner 
I was wondering if this is still the case. It looks like you’ve seen the thread where Mac High CPU usage is discussed (this one) and you are aware of the last update. I wish it was more than we are investigating. We are. Actively, but I’m afraid I don’t have any more information to share.
Would you like me to move this thread in our technical team’s queue, so they can take a closer look at your case?
