Figures from each repo's GitHub metadata at analysis time.
The app is not digitally signed by Apple, so you must adjust your Mac security settings to allow it to run, and admin privileges are required each time you toggle Turbo Boost.
Turbo Boost Switcher is a Mac utility that lets you turn Turbo Boost, a feature that makes your CPU run faster but hotter, on or off with a single click from your menu bar. The main reason people use it is to significantly reduce their Mac's temperature: the developer reports up to 20°C lower CPU temperatures with Turbo Boost disabled. Turbo Boost is a processor feature that automatically speeds up individual CPU cores when needed. The catch is that it pushes temperatures close to 100°C, which can spike fan speeds and potentially shorten your hardware's lifespan. The app works by installing a system-level extension that toggles this feature on or off, which is why it asks for your administrator password when you use it. This tool is aimed at Mac users who regularly run demanding tasks like video transcoding, photo editing in Photoshop, or casual gaming, activities that tend to send fans into overdrive and CPU temperatures into the 90s. If your Mac frequently sounds like it's about to take off during these workloads, this app offers a way to trade some raw speed for noticeably cooler, quieter operation. It also shows CPU temperature and fan speed in real time, and can automatically disable Turbo Boost when the app launches and re-enable it when you quit. One notable tradeoff: because the app modifies low-level system settings, macOS requires admin privileges each time you toggle the feature. A paid "PRO" version sidesteps this by running a background service, but the free version works fine if you don't mind entering your password. The app also isn't digitally signed by Apple, so you'll need to adjust your Mac's security settings to allow it to run.
A Mac menu bar app that lets you turn Turbo Boost on or off with one click, lowering CPU temperature by up to 20°C at the cost of some performance. It shows real-time temp and fan speed and can auto-disable Turbo Boost on launch.
