I reinstalled macOS and restored my data using Time Machine. After using the restored OS for a while, I discovered that
kernel_task's CPU usage is really high. I mainly use my Mac for music production, using Ableton as a DAW, and this prevented me from being able to open my simplest projects.
What I've tried so far:
- Searched the web and found out that there is a bug with Intel's Turbo Boost so I downloaded and installed Turbo Boost Switcher.
- Checked my hardware using the Mac tools and also scanned my disk partition.
- Reset SMC.
- Installed many versions of Ableton.
- Installed Fans and gfxcardstatus.
None of the above helped.
I'm using a MacBook Pro (Retina, 15", mid-2015) with a 2.5 GHz Intel Core i7 and 16 GB RAM with High Sierra 10.13.16.
Is there a way to troubleshoot the problem in a better way? I don't think that there is hardware damage involved. How can I solve this issue?
