It could also turn on the fans to avoid thermal throttling issues, although these are less common on Apple Silicon Macs. While there are no details on exactly how high power mode works, we assume that it will force the CPU and GPU to perform at their maximum performance whether the Mac is connected to power or not. While the “low power mode” already exists and reduces the performance of Mac laptops to save battery power, the “high power mode” should do the opposite by allowing users to run applications at full performance even when the Mac is not running. This feature was never made available to users and all references have been removed from the beta of macOS Monterey – until now.ĩto5Mac has now found references to a new “high power mode” added to macOS Monterey beta 8, which was released to developers earlier today. The macOS internal code described this option as something to make apps run faster, while also warning of reduced battery life and increased fan noise. The first references to “Pro Mode” were found in macOS Catalina 10.15.3.
Now, the latest version of macOS Monterey beta suggests that Apple is still working on a similar feature, now called “High Power Mode”. Back in January 2020, 9to5Mac reported that Apple is working on a new “Pro Mode” to allow MacBook users to achieve maximum performance by ignoring certain power saving restrictions.
