Could you clarify if the issue involves a fan speed adjustment or something else? I’ll help you determine if it’s fixable.
Macs Fan Control functions flawlessly here. It mainly impacts the HDD fan, though it rarely reaches full speed. Adjustments can be made using Macs Fan Control at no cost. The fan operates entirely through software—no physical sensor needed. Using a replacement sensor is mostly just a formality.
I'm having trouble getting this software to install on my Mac. I've tried all possible methods and haven't managed to get another Mac running before Catalina. Every attempt using transmac to make a bootable USB failed. In the boot menu, the USB drive isn't showing up. Could this be a damaged disk? I checked the Sierra and el Capitan dmg files directly from Apple's site, but there was no success.
