FranticJohny Posted February 3, 2017 Share Posted February 3, 2017 Hello dear community, I have a problem with my media machine. The first cpu core is always at 70% load from kernel_task and I cannot find the reason why. The OS is installed recently (10.12.3), everything is working fine (USB ports, sleep/wake, nvram, wifi, bluetooth). Here is the config: CPU: i3-4030U Graphics: HD4400 1st drive: 120GB SATA3 SSD 2nd drive: 500gb SATA2 HDD RAM: 4gb DDR3 1600mhz in first bank WIFI/BT: BCM94352HMB BIOS: CSM disabled, all CPU features enabled, Graphics Memory 32mb, AHCI enabled, unfortunetly there are no USB options in BIOS Clover: UEFI with AptioFix2Drv SMBIOS: MacMini7,1 I did modify the DSDT but even with stock DSDT/SSDT and without the BCM94352HMB the CPU load is still there. I tried to disable graphics injection and boot without display (vnc connection), but still the same issue. acpi_dump_origin.zip acpi_dump_origin_disassambled.zip CLOVER.zip DarwinDumper_3.0.2_02.02_22.27.56_Macmini7,1_AMI_X64_3978_Sierra_16D32_jens.zip Link to comment Share on other sites More sharing options...

FranticJohny Posted April 24, 2017 Author Share Posted April 24, 2017 Check CLOVER.zip What ur audio codec? I'll try this later at home, but I already tried to disable audio in BIOS and didn't inject any kexts/properties... the cpu load was still there. So I doubt it will work, but I'll try, thank you. The audio chip is ALC270 EDIT: The kernel_task CPU load is still there. 1 Link to comment Share on other sites More sharing options...

Have no clue what's the root of this issue. Maybe, ACPI related. Some info here: Edited October 25, 2023 by mrmacdi2 Link to comment Share on other sites More sharing options...
