Turbo-Boost-Switcher

It's not fixed though, it simply cripples the CPU in order to keep it cooler. This was already achievable by disabling Turbo Boost [0]. I can't tell which solution works better but before switching to an M1 Air I was running TBS on my 16" and it made things more acceptable. [0] https://github.com/rugarciap/Turbo-Boost-Switcher

I use a 15" 2018 MacBook Pro with the six-core i9 at work and Turbo Boost Switcher[1] has been my favourite discovery. It lets you disable the turbo boost function of the processor which means the fans never spin up and the battery lasts longer. I pretty much always leave it disabled unless I am going to be transcoding video or compiling something and can't notice a performance hit even with a couple of VMs running. The only bad thing is that it requires a kernel extension so will stop working when they are deprecated in 10.16. Hopefully Apple introduces a similar feature as there were rumours of a "Pro" mode coming which would ramp up the fans and clock, my hope is they add a complementary "quiet" mode or similar to disable turbo boost.

I know it's not protocol to talk down Show HN submissions. But this is just a shell script loading a core component of TBS [0] during login without password prompts: by saving your password in a plain text file. I can agree that password prompts at login are not the best user experience but security is there for a reason. Maybe TBS should implement this using the privileged helper pattern [1] which allow a small daemon with root permissions to perform actions for a userland application through a secure RPC channel.

If you're on a Mac and using OSX, I highly suggest checking out Turbo Boost switcher https://github.com/rugarciap/Turbo-Boost-Switcher It's given me at least an hour more of battery life on my aging Macbook Pro 13 (2011). Another handy tool on OSX is CoconutBattery which is basically the closest I've found to PowerTop for monitoring power usage (I know ActivityMonitor somewhat shows power usage BUT it makes my fans & CPU spin like crazy when it's gathering info!)
