Hey entresoft

I am also facing same issue. Constant high CPU usage by the system (ranges between 68-80%). Activity monitor says that kernel_task is hogging the max CPU (mostly greater then 200%)

Steps tried so far

1. Deleted temp and cache

2. Uninstalled flash

3. Created a new admin user account (The issue continued with the new account as well)

4. deleted mediaanalysisd.plist file - by doing this the issue resolved for few hours and then the issue resurfaced.

Please find below the entrechek result:
